-Jean Delvare <khali@linux-fr.org>

-
-This is a guide on how to convert I2C chip drivers from Linux 2.4 to
-Linux 2.6. I have been using existing drivers (lm75, lm78) as examples.
-Then I converted a driver myself (lm83) and updated this document.
-Note that this guide is strongly oriented towards hardware monitoring
-drivers. Many points are still valid for other type of drivers, but
-others may be irrelevant.
-
-There are two sets of points below. The first set concerns technical
-changes. The second set concerns coding policy. Both are mandatory.
-
-Although reading this guide will help you porting drivers, I suggest
-you keep an eye on an already ported driver while porting your own
-driver. This will help you a lot understanding what this guide
-exactly means. Choose the chip driver that is the more similar to
-yours for best results.
-
-Technical changes:
-
-* [Driver type] Any driver that was relying on i2c-isa has to be
- converted to a proper isa, platform or pci driver. This is not
- covered by this guide.
-
-* [Includes] Get rid of "version.h" and <linux/i2c-proc.h>.
- Includes typically look like that:
- #include <linux/module.h>
- #include <linux/init.h>
- #include <linux/slab.h>
- #include <linux/jiffies.h>
- #include <linux/i2c.h>
- #include <linux/hwmon.h> /* for hardware monitoring drivers */
- #include <linux/hwmon-sysfs.h>
- #include <linux/hwmon-vid.h> /* if you need VRM support */
- #include <linux/err.h> /* for class registration */
- Please respect this inclusion order. Some extra headers may be
- required for a given driver (e.g. "lm75.h").
-
-* [Addresses] SENSORS_I2C_END becomes I2C_CLIENT_END, ISA addresses
- are no more handled by the i2c core. Address ranges are no more
- supported either, define each individual address separately.
- SENSORS_INSMOD_<n> becomes I2C_CLIENT_INSMOD_<n>.
-
-* [Client data] Get rid of sysctl_id. Try using standard names for
- register values (for example, temp_os becomes temp_max). You're
- still relatively free here, but you *have* to follow the standard
- names for sysfs files (see the Sysctl section below).
-
-* [Function prototypes] The detect functions loses its flags
- parameter. Sysctl (e.g. lm75_temp) and miscellaneous functions
- are off the list of prototypes. This usually leaves five
- prototypes:
- static int lm75_attach_adapter(struct i2c_adapter *adapter);
- static int lm75_detect(struct i2c_adapter *adapter, int address,
- int kind);
- static void lm75_init_client(struct i2c_client *client);
- static int lm75_detach_client(struct i2c_client *client);
- static struct lm75_data lm75_update_device(struct device *dev);
-
-* [Sysctl] All sysctl stuff is of course gone (defines, ctl_table
- and functions). Instead, you have to define show and set functions for
- each sysfs file. Only define set for writable values. Take a look at an
- existing 2.6 driver for details (it87 for example). Don't forget
- to define the attributes for each file (this is that step that
- links callback functions). Use the file names specified in
- Documentation/hwmon/sysfs-interface for the individual files. Also
- convert the units these files read and write to the specified ones.
- If you need to add a new type of file, please discuss it on the
- sensors mailing list <lm-sensors@lm-sensors.org> by providing a
- patch to the Documentation/hwmon/sysfs-interface file.
-
-* [Attach] The attach function should make sure that the adapter's
- class has I2C_CLASS_HWMON (or whatever class is suitable for your
- driver), using the following construct:
- if (!(adapter->class & I2C_CLASS_HWMON))
- return 0;
- Call i2c_probe() instead of i2c_detect().
-
-* [Detect] As mentioned earlier, the flags parameter is gone.
- The type_name and client_name strings are replaced by a single
- name string, which will be filled with a lowercase, short string.
- The labels used for error paths are reduced to the number needed.
- It is advised that the labels are given descriptive names such as
- exit and exit_free. Don't forget to properly set err before
- jumping to error labels. By the way, labels should be left-aligned.
- Use kzalloc instead of kmalloc.
- Use i2c_set_clientdata to set the client data (as opposed to
- a direct access to client->data).
- Use strlcpy instead of strcpy or snprintf to copy the client name.
- Replace the sysctl directory registration by calls to
- device_create_file. Move the driver initialization before any
- sysfs file creation.
- Register the client with the hwmon class (using hwmon_device_register)
- if applicable.
- Drop client->id.
- Drop any 24RF08 corruption prevention you find, as this is now done
- at the i2c-core level, and doing it twice voids it.
- Don't add I2C_CLIENT_ALLOW_USE to client->flags, it's the default now.
-
-* [Init] Limits must not be set by the driver (can be done later in
- user-space). Chip should not be reset default (although a module
- parameter may be used to force it), and initialization should be
- limited to the strictly necessary steps.
-
-* [Detach] Remove the call to i2c_deregister_entry. Do not log an
- error message if i2c_detach_client fails, as i2c-core will now do
- it for you.
- Unregister from the hwmon class if applicable.
-
-* [Update] The function prototype changed, it is now
- passed a device structure, which you have to convert to a client
- using to_i2c_client(dev). The update function should return a
- pointer to the client data.
- Don't access client->data directly, use i2c_get_clientdata(client)
- instead.
- Use time_after() instead of direct jiffies comparison.
-
-* [Interface] Make sure there is a MODULE_LICENSE() line, at the bottom
- of the file (after MODULE_AUTHOR() and MODULE_DESCRIPTION(), in this
- order).
-
-* [Driver] The flags field of the i2c_driver structure is gone.
- I2C_DF_NOTIFY is now the default behavior.
- The i2c_driver structure has a driver member, which is itself a
- structure, those name member should be initialized to a driver name
- string. i2c_driver itself has no name member anymore.
-
-* [Driver model] Instead of shutdown or reboot notifiers, provide a
- shutdown() method in your driver.
-
-* [Power management] Use the driver model suspend() and resume()
- callbacks instead of the obsolete pm_register() calls.
-
-Coding policy:
-
-* [Copyright] Use (C), not (c), for copyright.
-
-* [Debug/log] Get rid of #ifdef DEBUG/#endif constructs whenever you
- can. Calls to printk for debugging purposes are replaced by calls to
- dev_dbg where possible, else to pr_debug. Here is an example of how
- to call it (taken from lm75_detect):
- dev_dbg(&client->dev, "Starting lm75 update\n");
- Replace other printk calls with the dev_info, dev_err or dev_warn
- function, as appropriate.
-
-* [Constants] Constants defines (registers, conversions) should be
- aligned. This greatly improves readability.
- Alignments are achieved by the means of tabs, not spaces. Remember
- that tabs are set to 8 in the Linux kernel code.
-
-* [Layout] Avoid extra empty lines between comments and what they
- comment. Respect the coding style (see Documentation/CodingStyle),
- in particular when it comes to placing curly braces.
-
-* [Comments] Make sure that no comment refers to a file that isn't
- part of the Linux source tree (typically doc/chips/<chip name>),
- and that remaining comments still match the code. Merging comment
- lines when possible is encouraged.

should match the module name (if the driver can be compiled as a module),
although you can use MODULE_ALIAS (passing "foo" in this example) to add
another name for the module. If the driver name doesn't match the module
name, the module won't be automatically loaded (hotplug/coldplug).

Probing and attaching
=====================
The Linux I2C stack was originally written to support access to hardware
-monitoring chips on PC motherboards, and thus it embeds some assumptions
-that are more appropriate to SMBus (and PCs) than to I2C. One of these
-assumptions is that most adapters and devices drivers support the SMBUS_QUICK
-protocol to probe device presence. Another is that devices and their drivers
+monitoring chips on PC motherboards, and thus used to embed some assumptions
+that were more appropriate to SMBus (and PCs) than to I2C. One of these
+assumptions was that most adapters and devices drivers support the SMBUS_QUICK
+protocol to probe device presence. Another was that devices and their drivers
can be sufficiently configured using only such probe primitives.
As Linux and its I2C stack became more widely used in embedded systems
objects after SMBus style probing, while the Linux driver model expects
drivers to be given such device objects in their probe() routines.
+The legacy model is deprecated now and will soon be removed, so we no
+longer document it here.
+
Standard Driver Model Binding ("New Style")
-------------------------------------------
the driver knows which one in the table matched.
-Device Creation (Standard driver model)
----------------------------------------
+Device Creation
+---------------
If you know for a fact that an I2C device is connected to a given I2C bus,
you can instantiate that device by simply filling an i2c_board_info
reference for later use.
-Device Detection (Standard driver model)
-----------------------------------------
+Device Detection
+----------------
Sometimes you do not know in advance which I2C devices are connected to
a given I2C bus. This is for example the case of hardware monitoring
quickly.
-Device Deletion (Standard driver model)
----------------------------------------
+Device Deletion
+---------------
Each I2C device which has been created using i2c_new_device() or
i2c_new_probed_device() can be unregistered by calling
device can't survive its parent in the device driver model.
-Legacy Driver Binding Model
----------------------------
+Initializing the driver
+=======================
+
+When the kernel is booted, or when your foo driver module is inserted,
+you have to do some initializing. Fortunately, just registering the
+driver module is usually enough.
-Most i2c devices can be present on several i2c addresses; for some this
-is determined in hardware (by soldering some chip pins to Vcc or Ground),
-for others this can be changed in software (by writing to specific client
-registers). Some devices are usually on a specific address, but not always;
-and some are even more tricky. So you will probably need to scan several
-i2c addresses for your clients, and do some sort of detection to see
-whether it is actually a device supported by your driver.
+static int __init foo_init(void)
+{
+ return i2c_add_driver(&foo_driver);
+}
+
+static void __exit foo_cleanup(void)
+{
+ i2c_del_driver(&foo_driver);
+}
+
+/* Substitute your own name and email address */
+MODULE_AUTHOR("Frodo Looijaard <frodol@dds.nl>"
+MODULE_DESCRIPTION("Driver for Barf Inc. Foo I2C devices");
-To give the user a maximum of possibilities, some default module parameters
-are defined to help determine what addresses are scanned. Several macros
-are defined in i2c.h to help you support them, as well as a generic
-detection algorithm.
-
-You do not have to use this parameter interface; but don't try to use
-function i2c_probe() if you don't.
-
-
-Probing classes (Legacy model)
-------------------------------
-
-All parameters are given as lists of unsigned 16-bit integers. Lists are
-terminated by I2C_CLIENT_END.
-The following lists are used internally:
-
- normal_i2c: filled in by the module writer.
- A list of I2C addresses which should normally be examined.
- probe: insmod parameter.
- A list of pairs. The first value is a bus number (-1 for any I2C bus),
- the second is the address. These addresses are also probed, as if they
- were in the 'normal' list.
- ignore: insmod parameter.
- A list of pairs. The first value is a bus number (-1 for any I2C bus),
- the second is the I2C address. These addresses are never probed.
- This parameter overrules the 'normal_i2c' list only.
- force: insmod parameter.
- A list of pairs. The first value is a bus number (-1 for any I2C bus),
- the second is the I2C address. A device is blindly assumed to be on
- the given address, no probing is done.
-
-Additionally, kind-specific force lists may optionally be defined if
-the driver supports several chip kinds. They are grouped in a
-NULL-terminated list of pointers named forces, those first element if the
-generic force list mentioned above. Each additional list correspond to an
-insmod parameter of the form force_<kind>.
-
-Fortunately, as a module writer, you just have to define the `normal_i2c'
-parameter. The complete declaration could look like this:
-
- /* Scan 0x4c to 0x4f */
- static const unsigned short normal_i2c[] = { 0x4c, 0x4d, 0x4e, 0x4f,
- I2C_CLIENT_END };
-
- /* Magic definition of all other variables and things */
- I2C_CLIENT_INSMOD;
- /* Or, if your driver supports, say, 2 kind of devices: */
- I2C_CLIENT_INSMOD_2(foo, bar);
-
-If you use the multi-kind form, an enum will be defined for you:
- enum chips { any_chip, foo, bar, ... }
-You can then (and certainly should) use it in the driver code.
-
-Note that you *have* to call the defined variable `normal_i2c',
-without any prefix!
-
-
-Attaching to an adapter (Legacy model)
---------------------------------------
-
-Whenever a new adapter is inserted, or for all adapters if the driver is
-being registered, the callback attach_adapter() is called. Now is the
-time to determine what devices are present on the adapter, and to register
-a client for each of them.
-
-The attach_adapter callback is really easy: we just call the generic
-detection function. This function will scan the bus for us, using the
-information as defined in the lists explained above. If a device is
-detected at a specific address, another callback is called.
-
- int foo_attach_adapter(struct i2c_adapter *adapter)
- {
- return i2c_probe(adapter,&addr_data,&foo_detect_client);
- }
-
-Remember, structure `addr_data' is defined by the macros explained above,
-so you do not have to define it yourself.
-
-The i2c_probe function will call the foo_detect_client
-function only for those i2c addresses that actually have a device on
-them (unless a `force' parameter was used). In addition, addresses that
-are already in use (by some other registered client) are skipped.
-
-
-The detect client function (Legacy model)
------------------------------------------
-
-The detect client function is called by i2c_probe. The `kind' parameter
-contains -1 for a probed detection, 0 for a forced detection, or a positive
-number for a forced detection with a chip type forced.
-
-Returning an error different from -ENODEV in a detect function will cause
-the detection to stop: other addresses and adapters won't be scanned.
-This should only be done on fatal or internal errors, such as a memory
-shortage or i2c_attach_client failing.
-
-For now, you can ignore the `flags' parameter. It is there for future use.
-
- int foo_detect_client(struct i2c_adapter *adapter, int address,
- int kind)
- {
- int err = 0;

- devices. */

- mutex_init(&data->update_lock); /* Only if you use this field */

- /* Any other initializations in data must be done here too. */

- needed. */

- very code-efficient in this case. */

- ERROR0:
- return err;
- }
-
-
-Removing the client (Legacy model)
-==================================
-
-The detach_client call back function is called when a client should be
-removed. It may actually fail, but only when panicking. This code is
-much simpler than the attachment code, fortunately!
-
- int foo_detach_client(struct i2c_client *client)
- {
- int err;
-
- /* Try to detach the client from i2c space */
- if ((err = i2c_detach_client(client)))
- return err;
-
- kfree(i2c_get_clientdata(client));
- return 0;
- }
-
-
-Initializing the module or kernel

+ Using the Linux Kernel Tracepoints
+
+ Mathieu Desnoyers
+
+
+This document introduces Linux Kernel Tracepoints and their use. It provides
+examples of how to insert tracepoints in the kernel and connect probe functions
+to them and provides some examples of probe functions.
+
+
+* Purpose of tracepoints
+
+A tracepoint placed in code provides a hook to call a function (probe) that you
+can provide at runtime. A tracepoint can be "on" (a probe is connected to it) or
+"off" (no probe is attached). When a tracepoint is "off" it has no effect,
+except for adding a tiny time penalty (checking a condition for a branch) and
+space penalty (adding a few bytes for the function call at the end of the
+instrumented function and adds a data structure in a separate section). When a
+tracepoint is "on", the function you provide is called each time the tracepoint
+is executed, in the execution context of the caller. When the function provided
+ends its execution, it returns to the caller (continuing from the tracepoint
+site).
+
+You can put tracepoints at important locations in the code. They are
+lightweight hooks that can pass an arbitrary number of parameters,
+which prototypes are described in a tracepoint declaration placed in a header
+file.
+
+They can be used for tracing and performance accounting.
+
+
+* Usage
+
+Two elements are required for tracepoints :
+
+- A tracepoint definition, placed in a header file.
+- The tracepoint statement, in C code.
+
+In order to use tracepoints, you should include linux/tracepoint.h.
+
+In include/trace/subsys.h :
+
+#include <linux/tracepoint.h>
+
+DEFINE_TRACE(subsys_eventname,
+ TPPTOTO(int firstarg, struct task_struct *p),
+ TPARGS(firstarg, p));
+
+In subsys/file.c (where the tracing statement must be added) :
+
+#include <trace/subsys.h>
+
+void somefct(void)
+{
+ ...
+ trace_subsys_eventname(arg, task);
+ ...
+}
+
+Where :
+- subsys_eventname is an identifier unique to your event
+ - subsys is the name of your subsystem.
+ - eventname is the name of the event to trace.
+- TPPTOTO(int firstarg, struct task_struct *p) is the prototype of the function
+ called by this tracepoint.
+- TPARGS(firstarg, p) are the parameters names, same as found in the prototype.
+
+Connecting a function (probe) to a tracepoint is done by providing a probe
+(function to call) for the specific tracepoint through
+register_trace_subsys_eventname(). Removing a probe is done through
+unregister_trace_subsys_eventname(); it will remove the probe sure there is no
+caller left using the probe when it returns. Probe removal is preempt-safe
+because preemption is disabled around the probe call. See the "Probe example"
+section below for a sample probe module.
+
+The tracepoint mechanism supports inserting multiple instances of the same
+tracepoint, but a single definition must be made of a given tracepoint name over
+all the kernel to make sure no type conflict will occur. Name mangling of the
+tracepoints is done using the prototypes to make sure typing is correct.
+Verification of probe type correctness is done at the registration site by the
+compiler. Tracepoints can be put in inline functions, inlined static functions,
+and unrolled loops as well as regular functions.
+
+The naming scheme "subsys_event" is suggested here as a convention intended
+to limit collisions. Tracepoint names are global to the kernel: they are
+considered as being the same whether they are in the core kernel image or in
+modules.
+
+
+* Probe / tracepoint example
+
+See the example provided in samples/tracepoints/src
+
+Compile them with your kernel.
+
+Run, as root :
+modprobe tracepoint-example (insmod order is not important)
+modprobe tracepoint-probe-example
+cat /proc/tracepoint-example (returns an expected error)
+rmmod tracepoint-example tracepoint-probe-example
+dmesg
$ echo mmiotrace > /debug/tracing/current_tracer
$ cat /debug/tracing/trace_pipe > mydump.txt &
Start X or whatever.
-$ echo "X is up" > /debug/tracing/marker
+$ echo "X is up" > /debug/tracing/trace_marker
$ echo none > /debug/tracing/current_tracer
Check for lost events.
Load the driver you want to trace and use it. Mmiotrace will only catch MMIO
accesses to areas that are ioremapped while mmiotrace is active.
-[Unimplemented feature:]
During tracing you can place comments (markers) into the trace by
-$ echo "X is up" > /debug/tracing/marker
+$ echo "X is up" > /debug/tracing/trace_marker
This makes it easier to see which part of the (huge) trace corresponds to
which action. It is recommended to place descriptive markers about what you
do.

+
+ Introduction
+
+UWB is a wide-band communication protocol that is to serve also as the
+low-level protocol for others (much like TCP sits on IP). Currently
+these others are Wireless USB and TCP/IP, but seems Bluetooth and
+Firewire/1394 are coming along.
+
+UWB uses a band from roughly 3 to 10 GHz, transmitting at a max of
+~-41dB (or 0.074 uW/MHz--geography specific data is still being
+negotiated w/ regulators, so watch for changes). That band is divided in
+a bunch of ~1.5 GHz wide channels (or band groups) composed of three
+subbands/subchannels (528 MHz each). Each channel is independent of each
+other, so you could consider them different "busses". Initially this
+driver considers them all a single one.
+
+Radio time is divided in 65536 us long /superframes/, each one divided
+in 256 256us long /MASs/ (Media Allocation Slots), which are the basic
+time/media allocation units for transferring data. At the beginning of
+each superframe there is a Beacon Period (BP), where every device
+transmit its beacon on a single MAS. The length of the BP depends on how
+many devices are present and the length of their beacons.
+
+Devices have a MAC (fixed, 48 bit address) and a device (changeable, 16
+bit address) and send periodic beacons to advertise themselves and pass
+info on what they are and do. They advertise their capabilities and a
+bunch of other stuff.
+
+The different logical parts of this driver are:
+
+ *
+
+ *UWB*: the Ultra-Wide-Band stack -- manages the radio and
+ associated spectrum to allow for devices sharing it. Allows to
+ control bandwidth assingment, beaconing, scanning, etc
+
+ *
+
+ *WUSB*: the layer that sits on top of UWB to provide Wireless USB.
+ The Wireless USB spec defines means to control a UWB radio and to
+ do the actual WUSB.
+
+
+ HWA: Host Wire adapters, your Wireless USB dongle
+
+WUSB also defines a device called a Host Wire Adaptor (HWA), which in
+mere terms is a USB dongle that enables your PC to have UWB and Wireless
+USB. The Wireless USB Host Controller in a HWA looks to the host like a
+[Wireless] USB controller connected via USB (!)
+
+The HWA itself is broken in two or three main interfaces:
+
+ *
+
+ *RC*: Radio control -- this implements an interface to the
+ Ultra-Wide-Band radio controller. The driver for this implements a
+ USB-based UWB Radio Controller to the UWB stack.
+
+ *
+
+ *HC*: the wireless USB host controller. It looks like a USB host
+ whose root port is the radio and the WUSB devices connect to it.
+ To the system it looks like a separate USB host. The driver (will)
+ implement a USB host controller (similar to UHCI, OHCI or EHCI)
+ for which the root hub is the radio...To reiterate: it is a USB
+ controller that is connected via USB instead of PCI.
+
+ *
+
+ *WINET*: some HW provide a WiNET interface (IP over UWB). This
+ package provides a driver for it (it looks like a network
+ interface, winetX). The driver detects when there is a link up for
+ their type and kick into gear.
+
+
+ DWA: Device Wired Adaptor, a Wireless USB hub for wired devices
+
+These are the complement to HWAs. They are a USB host for connecting
+wired devices, but it is connected to your PC connected via Wireless
+USB. To the system it looks like yet another USB host. To the untrained
+eye, it looks like a hub that connects upstream wirelessly.
+
+We still offer no support for this; however, it should share a lot of
+code with the HWA-RC driver; there is a bunch of factorization work that
+has been done to support that in upcoming releases.
+
+
+ WHCI: Wireless Host Controller Interface, the PCI WUSB host adapter
+
+This is your usual PCI device that implements WHCI. Similar in concept
+to EHCI, it allows your wireless USB devices (including DWAs) to connect
+to your host via a PCI interface. As in the case of the HWA, it has a
+Radio Control interface and the WUSB Host Controller interface per se.
+
+There is still no driver support for this, but will be in upcoming
+releases.
+
+
+ The UWB stack
+
+The main mission of the UWB stack is to keep a tally of which devices
+are in radio proximity to allow drivers to connect to them. As well, it
+provides an API for controlling the local radio controllers (RCs from
+now on), such as to start/stop beaconing, scan, allocate bandwidth, etc.
+
+
+ Devices and hosts: the basic structure
+
+The main building block here is the UWB device (struct uwb_dev). For
+each device that pops up in radio presence (ie: the UWB host receives a
+beacon from it) you get a struct uwb_dev that will show up in
+/sys/class/uwb and in /sys/bus/uwb/devices.
+
+For each RC that is detected, a new struct uwb_rc is created. In turn, a
+RC is also a device, so they also show in /sys/class/uwb and
+/sys/bus/uwb/devices, but at the same time, only radio controllers show
+up in /sys/class/uwb_rc.
+
+ *
+
+ [*] The reason for RCs being also devices is that not only we can
+ see them while enumerating the system device tree, but also on the
+ radio (their beacons and stuff), so the handling has to be
+ likewise to that of a device.
+
+Each RC driver is implemented by a separate driver that plugs into the
+interface that the UWB stack provides through a struct uwb_rc_ops. The
+spec creators have been nice enough to make the message format the same
+for HWA and WHCI RCs, so the driver is really a very thin transport that
+moves the requests from the UWB API to the device [/uwb_rc_ops->cmd()/]
+and sends the replies and notifications back to the API
+[/uwb_rc_neh_grok()/]. Notifications are handled to the UWB daemon, that
+is chartered, among other things, to keep the tab of how the UWB radio
+neighborhood looks, creating and destroying devices as they show up or
+dissapear.
+
+Command execution is very simple: a command block is sent and a event
+block or reply is expected back. For sending/receiving command/events, a
+handle called /neh/ (Notification/Event Handle) is opened with
+/uwb_rc_neh_open()/.
+
+The HWA-RC (USB dongle) driver (drivers/uwb/hwa-rc.c) does this job for
+the USB connected HWA. Eventually, drivers/whci-rc.c will do the same
+for the PCI connected WHCI controller.
+
+
+ Host Controller life cycle
+
+So let's say we connect a dongle to the system: it is detected and
+firmware uploaded if needed [for Intel's i1480
+/drivers/uwb/ptc/usb.c:ptc_usb_probe()/] and then it is reenumerated.
+Now we have a real HWA device connected and
+/drivers/uwb/hwa-rc.c:hwarc_probe()/ picks it up, that will set up the
+Wire-Adaptor environment and then suck it into the UWB stack's vision of
+the world [/drivers/uwb/lc-rc.c:uwb_rc_add()/].
+
+ *
+
+ [*] The stack should put a new RC to scan for devices
+ [/uwb_rc_scan()/] so it finds what's available around and tries to
+ connect to them, but this is policy stuff and should be driven
+ from user space. As of now, the operator is expected to do it
+ manually; see the release notes for documentation on the procedure.
+
+When a dongle is disconnected, /drivers/uwb/hwa-rc.c:hwarc_disconnect()/
+takes time of tearing everything down safely (or not...).
+
+
+ On the air: beacons and enumerating the radio neighborhood
+
+So assuming we have devices and we have agreed for a channel to connect
+on (let's say 9), we put the new RC to beacon:
+
+ *
+
+ $ echo 9 0 > /sys/class/uwb_rc/uwb0/beacon
+
+Now it is visible. If there were other devices in the same radio channel
+and beacon group (that's what the zero is for), the dongle's radio
+control interface will send beacon notifications on its
+notification/event endpoint (NEEP). The beacon notifications are part of
+the event stream that is funneled into the API with
+/drivers/uwb/neh.c:uwb_rc_neh_grok()/ and delivered to the UWBD, the UWB
+daemon through a notification list.
+
+UWBD wakes up and scans the event list; finds a beacon and adds it to
+the BEACON CACHE (/uwb_beca/). If he receives a number of beacons from
+the same device, he considers it to be 'onair' and creates a new device
+[/drivers/uwb/lc-dev.c:uwbd_dev_onair()/]. Similarly, when no beacons
+are received in some time, the device is considered gone and wiped out
+[uwbd calls periodically /uwb/beacon.c:uwb_beca_purge()/ that will purge
+the beacon cache of dead devices].
+
+
+ Device lists
+
+All UWB devices are kept in the list of the struct bus_type uwb_bus.
+
+
+ Bandwidth allocation
+
+The UWB stack maintains a local copy of DRP availability through
+processing of incoming *DRP Availability Change* notifications. This
+local copy is currently used to present the current bandwidth
+availability to the user through the sysfs file
+/sys/class/uwb_rc/uwbx/bw_avail. In the future the bandwidth
+availability information will be used by the bandwidth reservation
+routines.
+
+The bandwidth reservation routines are in progress and are thus not
+present in the current release. When completed they will enable a user
+to initiate DRP reservation requests through interaction with sysfs. DRP
+reservation requests from remote UWB devices will also be handled. The
+bandwidth management done by the UWB stack will include callbacks to the
+higher layers will enable the higher layers to use the reservations upon
+completion. [Note: The bandwidth reservation work is in progress and
+subject to change.]
+
+
+ Wireless USB Host Controller drivers
+
+*WARNING* This section needs a lot of work!
+
+As explained above, there are three different types of HCs in the WUSB
+world: HWA-HC, DWA-HC and WHCI-HC.
+
+HWA-HC and DWA-HC share that they are Wire-Adapters (USB or WUSB
+connected controllers), and their transfer management system is almost
+identical. So is their notification delivery system.
+
+HWA-HC and WHCI-HC share that they are both WUSB host controllers, so
+they have to deal with WUSB device life cycle and maintenance, wireless
+root-hub
+
+HWA exposes a Host Controller interface (HWA-HC 0xe0/02/02). This has
+three endpoints (Notifications, Data Transfer In and Data Transfer
+Out--known as NEP, DTI and DTO in the code).
+
+We reserve UWB bandwidth for our Wireless USB Cluster, create a Cluster
+ID and tell the HC to use all that. Then we start it. This means the HC
+starts sending MMCs.
+
+ *
+
+ The MMCs are blocks of data defined somewhere in the WUSB1.0 spec
+ that define a stream in the UWB channel time allocated for sending
+ WUSB IEs (host to device commands/notifications) and Device
+ Notifications (device initiated to host). Each host defines a
+ unique Wireless USB cluster through MMCs. Devices can connect to a
+ single cluster at the time. The IEs are Information Elements, and
+ among them are the bandwidth allocations that tell each device
+ when can they transmit or receive.
+
+Now it all depends on external stimuli.
+
+*New device connection*
+
+A new device pops up, it scans the radio looking for MMCs that give out
+the existence of Wireless USB channels. Once one (or more) are found,
+selects which one to connect to. Sends a /DN_Connect/ (device
+notification connect) during the DNTS (Device Notification Time
+Slot--announced in the MMCs
+
+HC picks the /DN_Connect/ out (nep module sends to notif.c for delivery
+into /devconnect/). This process starts the authentication process for
+the device. First we allocate a /fake port/ and assign an
+unauthenticated address (128 to 255--what we really do is
+0x80 | fake_port_idx). We fiddle with the fake port status and /khubd/
+sees a new connection, so he moves on to enable the fake port with a reset.
+
+So now we are in the reset path -- we know we have a non-yet enumerated
+device with an unauthorized address; we ask user space to authenticate
+(FIXME: not yet done, similar to bluetooth pairing), then we do the key
+exchange (FIXME: not yet done) and issue a /set address 0/ to bring the
+device to the default state. Device is authenticated.
+
+From here, the USB stack takes control through the usb_hcd ops. khubd
+has seen the port status changes, as we have been toggling them. It will
+start enumerating and doing transfers through usb_hcd->urb_enqueue() to
+read descriptors and move our data.
+
+*Device life cycle and keep alives*
+
+Everytime there is a succesful transfer to/from a device, we update a
+per-device activity timestamp. If not, every now and then we check and
+if the activity timestamp gets old, we ping the device by sending it a
+Keep Alive IE; it responds with a /DN_Alive/ pong during the DNTS (this
+arrives to us as a notification through
+devconnect.c:wusb_handle_dn_alive(). If a device times out, we
+disconnect it from the system (cleaning up internal information and
+toggling the bits in the fake hub port, which kicks khubd into removing
+the rest of the stuff).
+
+This is done through devconnect:__wusb_check_devs(), which will scan the
+device list looking for whom needs refreshing.
+
+If the device wants to disconnect, it will either die (ugly) or send a
+/DN_Disconnect/ that will prompt a disconnection from the system.
+
+*Sending and receiving data*
+
+Data is sent and received through /Remote Pipes/ (rpipes). An rpipe is
+/aimed/ at an endpoint in a WUSB device. This is the same for HWAs and
+DWAs.
+
+Each HC has a number of rpipes and buffers that can be assigned to them;
+when doing a data transfer (xfer), first the rpipe has to be aimed and
+prepared (buffers assigned), then we can start queueing requests for
+data in or out.
+
+Data buffers have to be segmented out before sending--so we send first a
+header (segment request) and then if there is any data, a data buffer
+immediately after to the DTI interface (yep, even the request). If our
+buffer is bigger than the max segment size, then we just do multiple
+requests.
+
+[This sucks, because doing USB scatter gatter in Linux is resource
+intensive, if any...not that the current approach is not. It just has to
+be cleaned up a lot :)].
+
+If reading, we don't send data buffers, just the segment headers saying
+we want to read segments.
+
+When the xfer is executed, we receive a notification that says data is
+ready in the DTI endpoint (handled through
+xfer.c:wa_handle_notif_xfer()). In there we read from the DTI endpoint a
+descriptor that gives us the status of the transfer, its identification
+(given when we issued it) and the segment number. If it was a data read,
+we issue another URB to read into the destination buffer the chunk of
+data coming out of the remote endpoint. Done, wait for the next guy. The
+callbacks for the URBs issued from here are the ones that will declare
+the xfer complete at some point and call it's callback.
+
+Seems simple, but the implementation is not trivial.
+
+ *
+
+ *WARNING* Old!!
+
+The main xfer descriptor, wa_xfer (equivalent to a URB) contains an
+array of segments, tallys on segments and buffers and callback
+information. Buried in there is a lot of URBs for executing the segments
+and buffer transfers.
+
+For OUT xfers, there is an array of segments, one URB for each, another
+one of buffer URB. When submitting, we submit URBs for segment request
+1, buffer 1, segment 2, buffer 2...etc. Then we wait on the DTI for xfer
+result data; when all the segments are complete, we call the callback to
+finalize the transfer.
+
+For IN xfers, we only issue URBs for the segments we want to read and
+then wait for the xfer result data.
+
+*URB mapping into xfers*
+
+This is done by hwahc_op_urb_[en|de]queue(). In enqueue() we aim an
+rpipe to the endpoint where we have to transmit, create a transfer
+context (wa_xfer) and submit it. When the xfer is done, our callback is
+called and we assign the status bits and release the xfer resources.
+
+In dequeue() we are basically cancelling/aborting the transfer. We issue
+a xfer abort request to the HC, cancell all the URBs we had submitted
+and not yet done and when all that is done, the xfer callback will be
+called--this will call the URB callback.

+
+ set-cc DEVICE
+
+ If we allow the device to connect, set a random new CDID and CK

- * interrupt, that is edge-triggered and unmasked by default. We
- * used to do this, but it caused problems on some systems because
- * of the NMI watchdog and sometimes IRQ0 of the 8254 timer using
- * the same ExtINT cascade interrupt to drive the local APIC of the

- * Region hash

- *
- * In addition to being present in the hash table a region _may_
- * be present on one of three lists.
- *
- * clean_regions: Regions on this list have no io pending to
- * them, they are in sync, we are no longer interested in them,
- * they are dull. rh_update_states() will remove them from the
- * hash table.
- *
- * quiesced_regions: These regions have been spun down, ready
- * for recovery. rh_recovery_start() will remove regions from
- * this list and hand them to kmirrord, which will schedule the
- * recovery io with kcopyd.
- *
- * recovered_regions: Regions that kcopyd has successfully
- * recovered. rh_update_states() will now schedule any delayed
- * io, up the recovery_count, and remove the region from the
- * hash.
- *
- * There are 2 locks:
- * A rw spin lock 'hash_lock' protects just the hash table,
- * this is never held in write mode from interrupt context,
- * which I believe means that we only have to disable irqs when
- * doing a write lock.
- *
- * An ordinary spin lock 'region_lock' that protects the three
- * lists in the region_hash, with the 'state', 'list' and
- * 'bhs_delayed' fields of the regions. This is used from irq
- * context, so all other uses will have to suspend local irqs.

+ * Region hash
+ *
+ * The mirror splits itself up into discrete regions. Each
+ * region can be in one of three states: clean, dirty,
+ * nosync. There is no need to put clean regions in the hash.
+ *
+ * In addition to being present in the hash table a region _may_
+ * be present on one of three lists.
+ *
+ * clean_regions: Regions on this list have no io pending to
+ * them, they are in sync, we are no longer interested in them,
+ * they are dull. dm_rh_update_states() will remove them from the
+ * hash table.
+ *
+ * quiesced_regions: These regions have been spun down, ready
+ * for recovery. rh_recovery_start() will remove regions from
+ * this list and hand them to kmirrord, which will schedule the
+ * recovery io with kcopyd.
+ *
+ * recovered_regions: Regions that kcopyd has successfully
+ * recovered. dm_rh_update_states() will now schedule any delayed
+ * io, up the recovery_count, and remove the region from the
+ * hash.
+ *
+ * There are 2 locks:
+ * A rw spin lock 'hash_lock' protects just the hash table,
+ * this is never held in write mode from interrupt context,
+ * which I believe means that we only have to disable irqs when
+ * doing a write lock.
+ *
+ * An ordinary spin lock 'region_lock' that protects the three
+ * lists in the region_hash, with the 'state', 'list' and
+ * 'delayed_bios' fields of the regions. This is used from irq
+ * context, so all other uses will have to suspend local irqs.

* pci_create_slot - create or increment refcount for physical PCI slot

* @name: user visible string presented in /sys/bus/pci/slots/<name>
+ * @hotplug: set if caller is hotplug driver, NULL otherwise
*
* PCI slots have first class attributes such as address, speed, width,
* and a &struct pci_slot is used to manage them. This interface will
* either return a new &struct pci_slot to the caller, or if the pci_slot
* already exists, its refcount will be incremented.
*
- * Slots are uniquely identified by a @pci_bus, @slot_nr, @name tuple.
+ * Slots are uniquely identified by a @pci_bus, @slot_nr tuple.
+ *
+ * There are known platforms with broken firmware that assign the same
+ * name to multiple slots. Workaround these broken platforms by renaming
+ * the slots on behalf of the caller. If firmware assigns name N to
+ * multiple slots:
+ *
+ * The first slot is assigned N
+ * The second slot is assigned N-1
+ * The third slot is assigned N-2
+ * etc.
*
* Placeholder slots:
* In most cases, @pci_bus, @slot_nr will be sufficient to uniquely identify
* the slot. In this scenario, the caller may pass -1 for @slot_nr.
*
* The following semantics are imposed when the caller passes @slot_nr ==
- * -1. First, the check for existing %struct pci_slot is skipped, as the
- * caller may know about several unpopulated slots on a given %struct
- * pci_bus, and each slot would have a @slot_nr of -1. Uniqueness for
- * these slots is then determined by the @name parameter. We expect
- * kobject_init_and_add() to warn us if the caller attempts to create
- * multiple slots with the same name. The other change in semantics is
+ * -1. First, we no longer check for an existing %struct pci_slot, as there
+ * may be many slots with @slot_nr of -1. The other change in semantics is
* user-visible, which is the 'address' parameter presented in sysfs will
* consist solely of a dddd:bb tuple, where dddd is the PCI domain of the
* %struct pci_bus and bb is the bus number. In other words, the devfn of
* the 'placeholder' slot will not be displayed.

- This is useful if you are developing a PnP driver or troubleshooting.

+ *
+ *
+ * WUSB devices have to be paired (associated in WUSB lingo) so
+ * that they can connect to the system.
+ *
+ * One way of pairing is using CBA-Cable Based Association. First
+ * time you plug the device with a cable, association is done between
+ * host and device and subsequent times, you can connect wirelessly
+ * without having to associate again. That's the idea.
+ *
+ * This driver does nothing Earth shattering. It just provides an
+ * interface to chat with the wire-connected device so we can get a
+ * CDID (device ID) that might have been previously associated to a
+ * CHID (host ID) and to set up a new <CHID,CDID,CK> triplet
+ * (connection context), with the CK being the secret, or connection
+ * key. This is the pairing data.
+ *
+ * When a device with the CBA capability connects, the probe routine
+ * just creates a bunch of sysfs files that a user space enumeration
+ * manager uses to allow it to connect wirelessly to the system or not.
+ *
+ * The process goes like this:
+ *
+ * 1. Device plugs, cbaf is loaded, notifications happen.
+ *
+ * 2. The connection manager (CM) sees a device with CBAF capability
+ * (the wusb_chid etc. files in /sys/devices/blah/OURDEVICE).
+ *
+ * 3. The CM writes the host name, supported band groups, and the CHID
+ * (host ID) into the wusb_host_name, wusb_host_band_groups and
+ * wusb_chid files. These get sent to the device and the CDID (if
+ * any) for this host is requested.
+ *
+ * 4. The CM can verify that the device's supported band groups
+ * (wusb_device_band_groups) are compatible with the host.
+ *
+ * 5. The CM reads the wusb_cdid file.
+ *
+ * 6. The CM looks up its database
+ *
+ * 6.1 If it has a matching CHID,CDID entry, the device has been
+ * authorized before (paired) and nothing further needs to be
+ * done.
+ *
+ * 6.2 If the CDID is zero (or the CM doesn't find a matching CDID in
+ * its database), the device is assumed to be not known. The CM
+ * may associate the host with device by: writing a randomly
+ * generated CDID to wusb_cdid and then a random CK to wusb_ck
+ * (this uploads the new CC to the device).
+ *
+ * CMD may choose to prompt the user before associating with a new
+ * device.
+ *
+ * 7. Device is unplugged.
+ *
+ * When the device tries to connect wirelessly, it will present its
+ * CDID to the WUSB host controller. The CM will query the
+ * database. If the CHID/CDID pair found, it will (with a 4-way
+ * handshake) challenge the device to demonstrate it has the CK secret
+ * key (from our database) without actually exchanging it. Once
+ * satisfied, crypto keys are derived from the CK, the device is
+ * connected and all communication is encrypted.

+ * So, device scans the radio, finds MMCs and thus a host and checks
+ * when the next DNTS is. It sends a Device Notification Connect
+ * (DN_Connect); the host picks it up (through nep.c and notif.c, ends
+ * up in wusb_devconnect_ack(), which creates a wusb_dev structure in
+ * wusbhc->port[port_number].wusb_dev), assigns an unauth address
+ * to the device (this means from 0x80 to 0xfe) and sends, in the MMC
+ * a Connect Ack Information Element (ConnAck IE).
+ *
+ * So now the device now has a WUSB address. From now on, we use
+ * that to talk to it in the RPipes.
+ *
+ * ASSUMPTIONS:
+ *
+ * - We use the the as device address the port number where it is
+ * connected (port 0 doesn't exist). For unauth, it is 128 + that.
+ *
+ * ROADMAP:
+ *
+ * This file contains the logic for doing that--entry points:
+ *
+ * wusb_devconnect_ack() Ack a device until _acked() called.
+ * Called by notif.c:wusb_handle_dn_connect()
+ * when a DN_Connect is received.
+ *
+ * wusbhc_devconnect_auth() Called by rh.c:wusbhc_rh_port_reset() when
+ * doing the device connect sequence.
+ *
+ * wusb_devconnect_acked() Ack done, release resources.
+ *
+ * wusb_handle_dn_alive() Called by notif.c:wusb_handle_dn()
+ * for processing a DN_Alive pong from a device.
+ *
+ * wusb_handle_dn_disconnect()Called by notif.c:wusb_handle_dn() to
+ * process a disconenct request from a
+ * device.
+ *
+ * wusb_dev_reset() Called by rh.c:wusbhc_rh_port_reset() when
+ * resetting a device.
+ *
+ * __wusb_dev_disable() Called by rh.c:wusbhc_rh_clear_port_feat() when
+ * disabling a port.
+ *
+ * wusb_devconnect_create() Called when creating the host by
+ * lc.c:wusbhc_create().
+ *
+ * wusb_devconnect_destroy() Cleanup called removing the host. Called
+ * by lc.c:wusbhc_destroy().
+ *
+ * Each Wireless USB host maintains a list of DN_Connect requests
+ * (actually we maintain a list of pending Connect Acks, the
+ * wusbhc->ca_list).
+ *
+ * LIFE CYCLE OF port->wusb_dev
+ *
+ * Before the @wusbhc structure put()s the reference it owns for
+ * port->wusb_dev [and clean the wusb_dev pointer], it needs to
+ * lock @wusbhc->mutex.

+ *
+ *
+ * This driver implements a USB Host Controller (struct usb_hcd) for a
+ * Wireless USB Host Controller based on the Wireless USB 1.0
+ * Host-Wire-Adapter specification (in layman terms, a USB-dongle that
+ * implements a Wireless USB host).
+ *
+ * Check out the Design-overview.txt file in the source documentation
+ * for other details on the implementation.
+ *
+ * Main blocks:
+ *
+ * driver glue with the driver API, workqueue daemon
+ *
+ * lc RC instance life cycle management (create, destroy...)
+ *
+ * hcd glue with the USB API Host Controller Interface API.
+ *
+ * nep Notification EndPoint managent: collect notifications
+ * and queue them with the workqueue daemon.
+ *
+ * Handle notifications as coming from the NEP. Sends them
+ * off others to their respective modules (eg: connect,
+ * disconnect and reset go to devconnect).
+ *
+ * rpipe Remote Pipe management; rpipe is what we use to write
+ * to an endpoint on a WUSB device that is connected to a
+ * HWA RC.
+ *
+ * xfer Transfer managment -- this is all the code that gets a
+ * buffer and pushes it to a device (or viceversa). *
+ *
+ * Some day a lot of this code will be shared between this driver and
+ * the drivers for DWA (xfer, rpipe).
+ *
+ * All starts at driver.c:hwahc_probe(), when one of this guys is
+ * connected. hwahc_disconnect() stops it.
+ *
+ * During operation, the main driver is devices connecting or
+ * disconnecting. They cause the HWA RC to send notifications into
+ * nep.c:hwahc_nep_cb() that will dispatch them to
+ * notif.c:wa_notif_dispatch(). From there they will fan to cause
+ * device connects, disconnects, etc.
+ *
+ * Note much of the activity is difficult to follow. For example a
+ * device connect goes to devconnect, which will cause the "fake" root
+ * hub port to show a connect and stop there. Then khubd will notice
+ * and call into the rh.c:hwahc_rc_port_reset() code to authenticate
+ * the device (and this might require user intervention) and enable
+ * the port.
+ *
+ * We also have a timer workqueue going from devconnect.c that
+ * schedules in hwahc_devconnect_create().
+ *
+ * The rest of the traffic is in the usual entry points of a USB HCD,
+ * which are hooked up in driver.c:hwahc_rc_driver, and defined in
+ * hcd.c.

+ * So what we do is we have this buffer and read into it; when a

+ * How transfers work: get a buffer, break it up in segments (segment
+ * size is a multiple of the maxpacket size). For each segment issue a
+ * segment request (struct wa_xfer_*), then send the data buffer if
+ * out or nothing if in (all over the DTO endpoint).
+ *
+ * For each submitted segment request, a notification will come over
+ * the NEP endpoint and a transfer result (struct xfer_result) will
+ * arrive in the DTI URB. Read it, get the xfer ID, see if there is
+ * data coming (inbound transfer), schedule a read and handle it.
+ *
+ * Sounds simple, it is a pain to implement.
+ *
+ *
+ * ENTRY POINTS
+ *
+ * FIXME
+ *
+ * LIFE CYCLE / STATE DIAGRAM
+ *
+ * FIXME
+ *
+ * THIS CODE IS DISGUSTING
+ *
+ * Warned you are; it's my second try and still not happy with it.
+ *
+ * NOTES:
+ *
+ * - No iso
+ *
+ * - Supports DMA xfers, control, bulk and maybe interrupt
+ *
+ * - Does not recycle unused rpipes
+ *
+ * An rpipe is assigned to an endpoint the first time it is used,
+ * and then it's there, assigned, until the endpoint is disabled
+ * (destroyed [{h,d}wahc_op_ep_disable()]. The assignment of the
+ * rpipe to the endpoint is done under the wa->rpipe_sem semaphore
+ * (should be a mutex).
+ *
+ * Two methods it could be done:
+ *
+ * (a) set up a timer everytime an rpipe's use count drops to 1
+ * (which means unused) or when a transfer ends. Reset the
+ * timer when a xfer is queued. If the timer expires, release
+ * the rpipe [see rpipe_ep_disable()].
+ *
+ * (b) when looking for free rpipes to attach [rpipe_get_by_ep()],
+ * when none are found go over the list, check their endpoint
+ * and their activity record (if no last-xfer-done-ts in the
+ * last x seconds) take it
+ *
+ * However, due to the fact that we have a set of limited
+ * resources (max-segments-at-the-same-time per xfer,
+ * xfers-per-ripe, blocks-per-rpipe, rpipes-per-host), at the end
+ * we are going to have to rebuild all this based on an scheduler,
+ * to where we have a list of transactions to do and based on the
+ * availability of the different requried components (blocks,
+ * rpipes, segment slots, etc), we go scheduling them. Painful.

+ * WUSB Host Controller specifics
+ *
+ * All fields that are common to all Wireless USB controller types
+ * (HWA and WHCI) are grouped here. Host Controller
+ * functions/operations that only deal with general Wireless USB HC
+ * issues use this data type to refer to the host.
+ *
+ * @usb_hcd Instantiation of a USB host controller
+ * (initialized by upper layer [HWA=HC or WHCI].
+ *
+ * @dev Device that implements this; initialized by the
+ * upper layer (HWA-HC, WHCI...); this device should
+ * have a refcount.
+ *
+ * @trust_timeout After this time without hearing for device
+ * activity, we consider the device gone and we have to
+ * re-authenticate.
+ *
+ * Can be accessed w/o locking--however, read to a
+ * local variable then use.
+ *
+ * @chid WUSB Cluster Host ID: this is supposed to be a
+ * unique value that doesn't change across reboots (so
+ * that your devices do not require re-association).
+ *
+ * Read/Write protected by @mutex
+ *
+ * @dev_info This array has ports_max elements. It is used to
+ * give the HC information about the WUSB devices (see
+ * 'struct wusb_dev_info').
+ *
+ * For HWA we need to allocate it in heap; for WHCI it
+ * needs to be permanently mapped, so we keep it for
+ * both and make it easy. Call wusbhc->dev_info_set()
+ * to update an entry.
+ *
+ * @ports_max Number of simultaneous device connections (fake
+ * ports) this HC will take. Read-only.
+ *
+ * @port Array of port status for each fake root port. Guaranteed to
+ * always be the same lenght during device existence
+ * [this allows for some unlocked but referenced reading].
+ *
+ * @mmcies_max Max number of Information Elements this HC can send
+ * in its MMC. Read-only.
+ *
+ * @mmcie_add HC specific operation (WHCI or HWA) for adding an
+ * MMCIE.
+ *
+ * @mmcie_rm HC specific operation (WHCI or HWA) for removing an
+ * MMCIE.
+ *
+ * @enc_types Array which describes the encryptions methods
+ * supported by the host as described in WUSB1.0 --
+ * one entry per supported method. As of WUSB1.0 there
+ * is only four methods, we make space for eight just in
+ * case they decide to add some more (and pray they do
+ * it in sequential order). if 'enc_types[enc_method]
+ * != 0', then it is supported by the host. enc_method
+ * is USB_ENC_TYPE*.
+ *
+ * @set_ptk: Set the PTK and enable encryption for a device. Or, if
+ * the supplied key is NULL, disable encryption for that
+ * device.
+ *
+ * @set_gtk: Set the GTK to be used for all future broadcast packets
+ * (i.e., MMCs). With some hardware, setting the GTK may start
+ * MMC transmission.
+ *
+ * NOTE:
+ *
+ * - If wusb_dev->usb_dev is not NULL, then usb_dev is valid
+ * (wusb_dev has a refcount on it). Likewise, if usb_dev->wusb_dev
+ * is not NULL, usb_dev->wusb_dev is valid (usb_dev keeps a
+ * refcount on it).
+ *
+ * Most of the times when you need to use it, it will be non-NULL,
+ * so there is no real need to check for it (wusb_dev will
+ * dissapear before usb_dev).
+ *
+ * - The following fields need to be filled out before calling
+ * wusbhc_create(): ports_max, mmcies_max, mmcie_{add,rm}.
+ *
+ * - there is no wusbhc_init() method, we do everything in
+ * wusbhc_create().
+ *
+ * - Creation is done in two phases, wusbhc_create() and
+ * wusbhc_create_b(); b are the parts that need to be called after
+ * calling usb_hcd_add(&wusbhc->usb_hcd).

+ * i1480u's RX handling is simple. i1480u will send the received
+ * network packets broken up in fragments; 1 to N fragments make a
+ * packet, we assemble them together and deliver the packet with netif_rx().
+ *
+ * Beacuse each USB transfer is a *single* fragment (except when the
+ * transfer contains a first fragment), each URB called thus
+ * back contains one or two fragments. So we queue N URBs, each with its own
+ * fragment buffer. When a URB is done, we process it (adding to the
+ * current skb from the fragment buffer until complete). Once
+ * processed, we requeue the URB. There is always a bunch of URBs
+ * ready to take data, so the intergap should be minimal.
+ *
+ * An URB's transfer buffer is the data field of a socket buffer. This
+ * reduces copying as data can be passed directly to network layer. If a
+ * complete packet or 1st fragment is received the URB's transfer buffer is
+ * taken away from it and used to send data to the network layer. In this
+ * case a new transfer buffer is allocated to the URB before being requeued.
+ * If a "NEXT" or "LAST" fragment is received, the fragment contents is
+ * appended to the RX packet under construction and the transfer buffer
+ * is reused. To be able to use this buffer to assemble complete packets
+ * we set each buffer's size to that of the MAX ethernet packet that can
+ * be received. There is thus room for improvement in memory usage.
+ *
+ * When the max tx fragment size increases, we should be able to read
+ * data into the skbs directly with very simple code.
+ *
+ * ROADMAP:
+ *
+ * ENTRY POINTS:

+ *
+ *
+ * The RC interface of the Host Wire Adapter (USB dongle) or WHCI PCI
+ * card delivers a stream of notifications and events to the
+ * notification end event endpoint or area. This code takes care of
+ * getting a buffer with that data, breaking it up in separate
+ * notifications and events and then deliver those.
+ *
+ * Events are answers to commands and they carry a context ID that
+ * associates them to the command. Notifications are that,
+ * notifications, they come out of the blue and have a context ID of
+ * zero. Think of the context ID kind of like a handler. The
+ * uwb_rc_neh_* code deals with managing context IDs.
+ *
+ * This is why you require a handle to operate on a UWB host. When you
+ * open a handle a context ID is assigned to you.
+ *
+ * So, as it is done is:
+ *
+ * 1. Add an event handler [uwb_rc_neh_add()] (assigns a ctx id)
+ * 2. Issue command [rc->cmd(rc, ...)]
+ * 3. Arm the timeout timer [uwb_rc_neh_arm()]
+ * 4, Release the reference to the neh [uwb_rc_neh_put()]
+ * 5. Wait for the callback
+ * 6. Command result (RCEB) is passed to the callback
+ *
+ * If (2) fails, you should remove the handle [uwb_rc_neh_rm()]
+ * instead of arming the timer.
+ *
+ * Handles are for using in *serialized* code, single thread.
+ *
+ * When the notification/event comes, the IRQ handler/endpoint
+ * callback passes the data read to uwb_rc_neh_grok() which will break
+ * it up in a discrete series of events, look up who is listening for
+ * them and execute the pertinent callbacks.
+ *
+ * If the reader detects an error while reading the data stream, call
+ * uwb_rc_neh_error().
+ *
+ * CONSTRAINTS/ASSUMPTIONS:
+ *
+ * - Most notifications/events are small (less thank .5k), copying
+ * around is ok.
+ *
+ * - Notifications/events are ALWAYS smaller than PAGE_SIZE
+ *
+ * - Notifications/events always come in a single piece (ie: a buffer
+ * will always contain entire notifications/events).
+ *
+ * - we cannot know in advance how long each event is (because they
+ * lack a length field in their header--smart move by the standards
+ * body, btw). So we need a facility to get the event size given the
+ * header. This is what the EST code does (notif/Event Size
+ * Tables), check nest.c--as well, you can associate the size to
+ * the handle [w/ neh->extra_size()].
+ *
+ * - Most notifications/events are fixed size; only a few are variable
+ * size (NEST takes care of that).
+ *
+ * - Listeners of events expect them, so they usually provide a
+ * buffer, as they know the size. Listeners to notifications don't,
+ * so we allocate their buffers dynamically.

+ *
+ * This daemon takes care of maintaing information that describes the
+ * UWB neighborhood that the radios in this machine can see. It also
+ * keeps a tab of which devices are visible, makes sure each HC sits
+ * on a different channel to avoid interfering, etc.
+ *
+ * Different drivers (radio controller, device, any API in general)
+ * communicate with this daemon through an event queue. Daemon wakes
+ * up, takes a list of events and handles them one by one; handling
+ * function is extracted from a table based on the event's type and
+ * subtype. Events are freed only if the handling function says so.
+ *
+ * . Lock protecting the event list has to be an spinlock and locked
+ * with IRQSAVE because it might be called from an interrupt
+ * context (ie: when events arrive and the notification drops
+ * down from the ISR).
+ *
+ * . UWB radio controller drivers queue events to the daemon using
+ * uwbd_event_queue(). They just get the event, chew it to make it
+ * look like UWBD likes it and pass it in a buffer allocated with
+ * uwb_event_alloc().
+ *
+ * EVENTS
+ *
+ * Events have a type, a subtype, a lenght, some other stuff and the
+ * data blob, which depends on the event. The header is 'struct
+ * uwb_event'; for payloads, see 'struct uwbd_evt_*'.
+ *
+ * EVENT HANDLER TABLES
+ *
+ * To find a handling function for an event, the type is used to index
+ * a subtype-table in the type-table. The subtype-table is indexed
+ * with the subtype to get the function that handles the event. Start
+ * with the main type-table 'uwbd_evt_type_handler'.
+ *
+ * DEVICES
+ *
+ * Devices are created when a bunch of beacons have been received and
+ * it is stablished that the device has stable radio presence. CREATED
+ * only, not configured. Devices are ONLY configured when an
+ * Application-Specific IE Probe is receieved, in which the device
+ * declares which Protocol ID it groks. Then the device is CONFIGURED
+ * (and the driver->probe() stuff of the device model is invoked).
+ *
+ * Devices are considered disconnected when a certain number of
+ * beacons are not received in an amount of time.
+ *
+ * Handler functions are called normally uwbd_evt_handle_*().

+ * We need to be able to map ethernet addresses to device addresses
+ * and back because there is not explicit relationship between the eth
+ * addresses used in the ETH frames and the device addresses (no, it
+ * would not have been simpler to force as ETH address the MBOA MAC
+ * address...no, not at all :).
+ *
+ * A device has one MBOA MAC address and one device address. It is possible
+ * for a device to have more than one virtual MAC address (although a
+ * virtual address can be the same as the MBOA MAC address). The device
+ * address is guaranteed to be unique among the devices in the extended
+ * beacon group (see ECMA 17.1.1). We thus use the device address as index
+ * to this cache. We do allow searching based on virtual address as this
+ * is how Ethernet frames will be addressed.
+ *
+ * We need to support virtual EUI-48. Although, right now the virtual
+ * EUI-48 will always be the same as the MAC SAP address. The EDA cache
+ * entry thus contains a MAC SAP address as well as the virtual address
+ * (used to map the network stack address to a neighbor). When we move
+ * to support more than one virtual MAC on a host then this organization
+ * will have to change. Perhaps a neighbor has a list of WSSs, each with a
+ * tag and virtual EUI-48.
+ *
+ * On data transmission
+ * it is used to determine if the neighbor is connected and what WSS it
+ * belongs to. With this we know what tag to add to the WLP frame. Storing
+ * the WSS in the EDA cache may be overkill because we only support one
+ * WSS. Hopefully we will support more than one WSS at some point.
+ * On data reception it is used to determine the WSS based on
+ * the tag and address of the transmitting neighbor.

+ *
+ * The network stack (WLP client) is attempting to transmit a frame. We can
+ * only transmit data if a local WSS is at least active (connection will be
+ * done here if this is a broadcast frame and neighbor also has the WSS
+ * active).
+ *
+ * The frame can be either broadcast or unicast. Broadcast in a WSS is
+ * supported via multicast, but we don't support multicast yet (until
+ * devices start to support MAB IEs). If a broadcast frame needs to be
+ * transmitted it is treated as a unicast frame to each neighbor. In this
+ * case the WLP takes over transmission of the skb and returns 1
+ * to the caller to indicate so. Also, in this case, if a neighbor has the
+ * same WSS activated but is not connected then the WSS connection will be
+ * done at this time. The neighbor's virtual address will be learned at
+ * this time.
+ *
+ * The destination address in a unicast frame is the virtual address of the
+ * neighbor. This address only becomes known when a WSS connection is
+ * established. We thus rely on a broadcast frame to trigger the setup of
+ * WSS connections to all neighbors before we are able to send unicast
+ * frames to them. This seems reasonable as IP would usually use ARP first
+ * before any unicast frames are sent.
+ *
+ * If we are already connected to the neighbor (neighbor's virtual address
+ * is known) we just prepare the WLP header and the caller will continue to
+ * send the frame.
+ *
+ * A failure in this function usually indicates something that cannot be
+ * fixed automatically. So, if this function fails (@return < 0) the calling
+ * function should not retry to send the frame as it will very likely keep
+ * failing.

+------------
+Various fixes to make delete of open files behavior more predictable
+(when delete of an open file fails we mark the file as "delete-on-close"
+in a way that more servers accept, but only if we can first rename the
+file to a temporary name). Add experimental support for more safely
+handling fcntl(F_SETLEASE).
+
Version 1.54
------------
Fix premature write failure on congested networks (we would give up
authentication (requires setting SecurityFlags to 0x30030 to enable
lanman and plain text though). Fix writes to be at correct offset when
file is open with O_APPEND and file is on a directio (forcediretio) mount.
+Fix bug in rewinding readdir directory searches. Add nodfs mount option.
Version 1.53
------------
with cifs style mandatory byte range locks (and most
cifs servers do not yet support requesting advisory
byte range locks).
+ nodfs Disable DFS (global name space support) even if the
+ server claims to support it. This can help work around
+ a problem with parsing of DFS paths with Samba 3.0.24 server.

shares mounted to the same server are unaffected.
+ locallease This option is rarely needed. Fcntl F_SETLEASE is
+ used by some applications such as Samba and NFSv4 server to
+ check to see whether a file is cacheable. CIFS has no way
+ to explicitly request a lease, but can check whether a file
+ is cacheable (oplocked). Unfortunately, even if a file
+ is not oplocked, it could still be cacheable (ie cifs client
+ could grant fcntl leases if no other local processes are using
+ the file) for cases for example such as when the server does not
+ support oplocks and the user is sure that the only updates to
+ the file will be from this client. Specifying this mount option
+ will allow the cifs client to check for leases (only) locally
+ for files which are not oplocked instead of denying leases
+ in that case. (EXPERIMENTAL)

none attempt to connection as a null user (no name)

+ * UMC (UWB Multi-interface Controller) capabilities (e.g., radio

+ *
+ * The radio controller is not strictly a UMC capability but it's

+ * References:
+ *
+ * [WHCI] Wireless Host Controller Interface Specification for
+ * Certified Wireless Universal Serial Bus, revision 0.95.
+ *
+ * How this works is kind of convoluted but simple. The whci.ko driver
+ * loads when WHCI devices are detected. These WHCI devices expose
+ * many devices in the same PCI function (they couldn't have reused
+ * functions, no), so for each PCI function that exposes these many
+ * devices, whci ceates a umc_dev [whci_probe() -> whci_add_cap()]
+ * with umc_device_create() and adds it to the bus with
+ * umc_device_register().
+ *
+ * umc_device_register() calls device_register() which will push the
+ * bus management code to load your UMC driver's somehting_probe()
+ * that you have registered for that capability code.
+ *
+ * Now when the WHCI device is removed, whci_remove() will go over
+ * each umc_dev assigned to each of the PCI function's capabilities
+ * and through whci_del_cap() call umc_device_unregister() each
+ * created umc_dev. Of course, if you are bound to the device, your
+ * driver's something_remove() will be called.

+ representation of the delays during initcalls - but the raw
+ /debug/tracing/trace text output is readable too.

+
+ This tracer works by hooking into every function call that the
+ kernel executes, and keeping a maximum stack depth value and
+ stack-trace saved. Because this logic has to execute in every
+ kernel function, all the time, this option can slow down the
+ kernel measurably and is generally intended for kernel

+# recordmcount.pl - makes a section called __mcount_loc that holds
+# all the offsets to the calls to mcount.
+#
+#
+# What we want to end up with is a section in vmlinux called
+# __mcount_loc that contains a list of pointers to all the
+# call sites in the kernel that call mcount. Later on boot up, the kernel
+# will read this list, save the locations and turn them into nops.
+# When tracing or profiling is later enabled, these locations will then
+# be converted back to pointers to some function.
+#
+# This is no easy feat. This script is called just after the original
+# object is compiled and before it is linked.
+#
+# The references to the call sites are offsets from the section of text
+# that the call site is in. Hence, all functions in a section that
+# has a call site to mcount, will have the offset from the beginning of
+# the section and not the beginning of the function.
+#
+# The trick is to find a way to record the beginning of the section.
+# The way we do this is to look at the first function in the section
+# which will also be the location of that section after final link.
+# e.g.
+#
+# .section ".text.sched"
+# .globl my_func
+# my_func:
+# [...]
+# call mcount (offset: 0x5)
+# [...]
+# ret
+# other_func:
+# [...]
+# call mcount (offset: 0x1b)
+# [...]
+#
+# Both relocation offsets for the mcounts in the above example will be
+# offset from .text.sched. If we make another file called tmp.s with:
+#
+# .section __mcount_loc
+# .quad my_func + 0x5
+# .quad my_func + 0x1b
+#
+# We can then compile this tmp.s into tmp.o, and link it to the original
+# object.
+#
+# But this gets hard if my_func is not globl (a static function).
+# In such a case we have:
+#
+# .section ".text.sched"
+# my_func:
+# [...]
+# call mcount (offset: 0x5)
+# [...]
+# ret
+# .globl my_func
+# other_func:
+# [...]
+# call mcount (offset: 0x1b)
+# [...]
+#
+# If we make the tmp.s the same as above, when we link together with
+# the original object, we will end up with two symbols for my_func:
+# one local, one global. After final compile, we will end up with
+# an undefined reference to my_func.
+#
+# Since local objects can reference local variables, we need to find
+# a way to make tmp.o reference the local objects of the original object
+# file after it is linked together. To do this, we convert the my_func
+# into a global symbol before linking tmp.o. Then after we link tmp.o
+# we will only have a single symbol for my_func that is global.
+# We can convert my_func back into a local symbol and we are done.
+#
+# Here are the steps we take:
+#
+# 1) Record all the local symbols by using 'nm'
+# 2) Use objdump to find all the call site offsets and sections for
+# mcount.
+# 3) Compile the list into its own object.
+# 4) Do we have to deal with local functions? If not, go to step 8.
+# 5) Make an object that converts these local functions to global symbols
+# with objcopy.
+# 6) Link together this new object with the list object.
+# 7) Convert the local functions back to local symbols and rename
+# the result as the original object.
+# End.
+# 8) Link the object with the list object.
+# 9) Move the result back to the original object.
+# End.
