point out some special detail about the sign-off.
+13) When to use Acked-by:
-13) The canonical patch format
+The Signed-off-by: tag indicates that the signer was involved in the
+development of the patch, or that he/she was in the patch's delivery path.
+
+If a person was not directly involved in the preparation or handling of a
+patch but wishes to signify and record their approval of it then they can
+arrange to have an Acked-by: line added to the patch's changelog.
+
+Acked-by: is often used by the maintainer of the affected code when that
+maintainer neither contributed to nor forwarded the patch.
+
+Acked-by: is not as formal as Signed-off-by:. It is a record that the acker
+has at least reviewed the patch and has indicated acceptance. Hence patch
+mergers will sometimes manually convert an acker's "yep, looks good to me"
+into an Acked-by:.
+
+Acked-by: does not necessarily indicate acknowledgement of the entire patch.
+For example, if a patch affects multiple subsystems and has an Acked-by: from
+one subsystem maintainer then this usually indicates acknowledgement of just
+the part which affects that maintainer's code. Judgement should be used here.
+ When in doubt people should refer to the original discussion in the mailing
+list archives.
+
+
+14) The canonical patch format
The canonical patch subject line is:
void smp_mb__before_atomic_dec(void);
void smp_mb__after_atomic_dec(void);
void smp_mb__before_atomic_inc(void);
- void smp_mb__after_atomic_dec(void);
+ void smp_mb__after_atomic_inc(void);
For example, smp_mb__before_atomic_dec() can be used like so:
calls to clk_get(&pdev->dev, clock_name) return them as needed.
+Legacy Drivers: Device Probing
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+Some drivers are not fully converted to the driver model, because they take
+on a non-driver role: the driver registers its platform device, rather than
+leaving that for system infrastructure. Such drivers can't be hotplugged
+or coldplugged, since those mechanisms require device creation to be in a
+different system component than the driver.
+
+The only "good" reason for this is to handle older system designs which, like
+original IBM PCs, rely on error-prone "probe-the-hardware" models for hardware
+configuration. Newer systems have largely abandoned that model, in favor of
+bus-level support for dynamic configuration (PCI, USB), or device tables
+provided by the boot firmware (e.g. PNPACPI on x86). There are too many
+conflicting options about what might be where, and even educated guesses by
+an operating system will be wrong often enough to make trouble.
+
+This style of driver is discouraged. If you're updating such a driver,
+please try to move the device enumeration to a more appropriate location,
+outside the driver. This will usually be cleanup, since such drivers
+tend to already have "normal" modes, such as ones using device nodes that
+were created by PNP or by platform device setup.
+
+None the less, there are some APIs to support such legacy drivers. Avoid
+using these calls except with such hotplug-deficient drivers.
+
+ struct platform_device *platform_device_alloc(
+ char *name, unsigned id);
+
+You can use platform_device_alloc() to dynamically allocate a device, which
+you will then initialize with resources and platform_device_register().
+A better solution is usually:
+
+ struct platform_device *platform_device_register_simple(
+ char *name, unsigned id,
+ struct resource *res, unsigned nres);
+
+You can use platform_device_register_simple() as a one-step call to allocate
+and register a device.
+
+
Device Naming and Driver Binding
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
The platform_device.dev.bus_id is the canonical name for the devices.
What: remove EXPORT_SYMBOL(kernel_thread)
When: August 2006
Files: arch/*/kernel/*_ksyms.c
+Funcs: kernel_thread
Why: kernel_thread is a low-level implementation detail. Drivers should
use the <linux/kthread.h> API instead which shields them from
implementation details and provides a higherlevel interface that
Note that trying to mount a tmpfs with an mpol option will fail if the
running kernel does not support NUMA; and will fail if its nodelist
-specifies a node >= MAX_NUMNODES. If your system relies on that tmpfs
-being mounted, but from time to time runs a kernel built without NUMA
-capability (perhaps a safe recovery kernel), or configured to support
-fewer nodes, then it is advisable to omit the mpol option from automatic
+specifies a node which is not online. If your system relies on that
+tmpfs being mounted, but from time to time runs a kernel built without
+NUMA capability (perhaps a safe recovery kernel), or with fewer nodes
+online, then it is advisable to omit the mpol option from automatic
mount options. It can be added later, when the tmpfs is already mounted
on MountPoint, by 'mount -o remount,mpol=Policy:NodeList MountPoint'.

+Firmware is required for this device: http://accessrunner.sourceforge.net/
+
+While it is capable of managing/maintaining the ADSL connection without the
+module loaded, the device will sometimes stop responding after unloading the
+driver and it is necessary to unplug/remove power to the device to fix this.
+
+Detected devices will appear as ATM devices named "cxacru". In /sys/class/atm/
+these are directories named cxacruN where N is the device number. A symlink
+named device points to the USB interface device's directory which contains
+several sysfs attribute files for retrieving device statistics:
+
+* adsl_controller_version
+
+* adsl_headend
+* adsl_headend_environment
+ Information about the remote headend.
+
+* downstream_attenuation (dB)
+* downstream_bits_per_frame
+* downstream_rate (kbps)
+* downstream_snr_margin (dB)
+ Downstream stats.
+
+* upstream_attenuation (dB)
+* upstream_bits_per_frame
+* upstream_rate (kbps)
+* upstream_snr_margin (dB)
+* transmitter_power (dBm/Hz)
+ Upstream stats.

+* downstream_hec_errors
+* upstream_crc_errors
+* upstream_fec_errors
+* upstream_hec_errors
+ Error counts.
+
+* line_startable
+ Indicates that ADSL support on the device
+ is/can be enabled, see adsl_start.
+
+* line_status
+ "initialising"
+ "down"
+ "attempting to activate"
+ "training"
+ "channel analysis"
+ "exchange"
+ "waiting"
+ "up"
+
+ Changes between "down" and "attempting to activate"
+ if there is no signal.

+
+* modulation
+ "ANSI T1.413"
+ "ITU-T G.992.1 (G.DMT)"
+ "ITU-T G.992.2 (G.LITE)"
+
+* startup_attempts
+ Count of total attempts to initialise ADSL.
+
+To enable/disable ADSL, the following can be written to the adsl_state file:
+ "start"
+ "stop
+ "restart" (stops, waits 1.5s, then starts)
+ "poll" (used to resume status polling if it was disabled due to failure)
+
+Changes in adsl/line state are reported via kernel log messages:
+ [4942145.150704] ATM dev 0: ADSL state: running
+ [4942243.663766] ATM dev 0: ADSL line: down

BT Commands:
- The blinding table (BT) contains a list of mac addresses that should be
- ignored by the firmware. It is primarily used for debugging and
- testing networks. It can be edited and inspected with the following
- commands:
+ The blinding table (BT) contains a list of mac addresses that will be,
+ by default, ignored by the firmware. It is also possible to invert this
+ behavior so that we will ignore all traffic except for the portion
+ coming from mac addresess in the list. It is primarily used for
+ debugging and testing networks. It can be edited and inspected with
+ the following commands:
iwpriv ethX bt_reset
iwpriv ethX bt_add <mac_address>
iwpriv ethX bt_del <mac_address>
iwpriv ethX bt_list <id>
+ iwpriv ethX bt_get_invert <n>
+ iwpriv ethX bt_set_invert <n>
FWT Commands:
The forwarding table (FWT) is a feature used to manage mesh network
This command is used to insert an entry into the FWT table. The list of
parameters must follow the following structure:
- iwpriv ethX fwt_add da ra [metric dir ssn dsn hopcount ttl expiration sleepmode snr]
+ iwpriv ethX fwt_add da ra [metric dir rate ssn dsn hopcount ttl expiration sleepmode snr]
The parameters between brackets are optional, but they must appear in
the order specified. For example, if you want to specify the metric,
preferred, default is 0)
dir -- direction (1 for direct, 0 for reverse,
default is 1)
+ rate -- data rate used for transmission to the RA,
+ as specified for the rateadapt command,
+ default is 3 (11Mbps)
ssn -- Source Sequence Number (time at the RA for
reverse routes. Default is 0)
dsn -- Destination Sequence Number (time at the DA
The output is a string of the following form:
- da ra metric dir ssn dsn hopcount ttl expiration sleepmode snr
+ da ra valid metric dir rate ssn dsn hopcount ttl expiration
+ sleepmode snr precursor
where the different fields are:-
da -- DA MAC address (in the form "00:11:22:33:44:55")
ra -- RA MAC address (in the form "00:11:22:33:44:55")
+ valid -- whether the route is valid (0 if not valid)
metric -- route metric (cost: smaller-metric routes are preferred)
dir -- direction (1 for direct, 0 for reverse)
+ rate -- data rate used for transmission to the RA,
+ as specified for the rateadapt command
ssn -- Source Sequence Number (time at the RA for reverse routes)
dsn -- Destination Sequence Number (time at the DA for direct routes)
hopcount -- hop count (currently unused)
expiration -- entry expiration (in ticks, where a tick is 1024us, or ~ 1ms. Use 0 for an indefinite entry)
sleepmode -- RA's sleep mode (currently unused)
snr -- SNR in the link to RA (currently unused)
+ precursor -- predecessor in direct routes
fwt_list_route
- This command is used to list a route from the FWT table. The only
- parameter is the route ID. If you want to list all the routes in a
- table, start with rid=0, and keep incrementing rid until you get a
- "(null)" string. This function is similar to fwt_list. The only
- difference is the output format. Also note that this command is meant
- for debugging. It is expected that users will use fwt_lookup and
- fwt_list. One important reason for this is that the route id may change
- as the route table is altered.
-
- iwpriv ethX fwt_list_route rid
-
- The output is a string of the following form:
-
- da metric dir nid ssn dsn hopcount ttl expiration
-
- where the different fields are:-
- da -- DA MAC address (in the form "00:11:22:33:44:55")
- metric -- route metric (cost: smaller-metric routes are preferred)
- dir -- direction (1 for direct, 0 for reverse)
- nid -- Next-hop (neighbor) host ID (nid)
- ssn -- Source Sequence Number (time at the RA for reverse routes)
- dsn -- Destination Sequence Number (time at the DA for direct routes)
- hopcount -- hop count (currently unused)
- ttl -- TTL count (only used in reverse entries)
- expiration -- entry expiration (in ticks, where a tick is 1024us, or ~ 1ms. Use 0 for an indefinite entry)
+ This command is equivalent to fwt_list.
fwt_list_neigh
This command is used to list a neighbor from the FWT table. The only

Userspace access to USB devices is granted by device-nodes exported
directly from the usbdev in sysfs. Old versions of the driver
core and udev needed additional class devices to export device nodes.
These additional devices are difficult to handle in userspace, if
- information about USB interfaces must be available. One device contains
- the device node, the other device contains the interface data. Both
- devices are at the same level in sysfs (siblings) and one can't access
- the other. The device node created directly by the usbdev is the parent
- device of the interface and therefore easily accessible from the interface
- event.
-
- This option provides backward compatibility if needed.

*
* Given a buffer of u8 data, print_hex_dump() prints a hex + ASCII dump
* to the kernel log at the specified kernel log level, with an optional
* leading prefix.
*
+ * print_hex_dump() works on one "line" of output at a time, i.e.,
+ * 16 or 32 bytes of input data converted to hex + ASCII output.
+ * print_hex_dump() iterates over the entire input @buf, breaking it into
+ * "line size" chunks to format and print.
+ *
* E.g.:
- * print_hex_dump(KERN_DEBUG, DUMP_PREFIX_ADDRESS, frame->data, frame->len);
+ * print_hex_dump(KERN_DEBUG, "raw data: ", DUMP_PREFIX_ADDRESS,
+ * 16, 1, frame->data, frame->len, 1);
*
- * Example output using %DUMP_PREFIX_OFFSET:
- * 0009ab42: 40414243 44454647 48494a4b 4c4d4e4f @ABCDEFGHIJKLMNO
- * Example output using %DUMP_PREFIX_ADDRESS:
