+Managing bug reports
+--------------------
+
+One of the best ways to put into practice your hacking skills is by fixing
+bugs reported by other people. Not only you will help to make the kernel
+more stable, you'll learn to fix real world problems and you will improve
+your skills, and other developers will be aware of your presence. Fixing
+bugs is one of the best ways to get merits among other developers, because
+not many people like wasting time fixing other people's bugs.
+
+To work in the already reported bug reports, go to http://bugzilla.kernel.org.
+If you want to be advised of the future bug reports, you can subscribe to the
+bugme-new mailing list (only new bug reports are mailed here) or to the
+bugme-janitor mailing list (every change in the bugzilla is mailed here)

-6. FAQ
+6. MSI quirks
+
+Several PCI chipsets or devices are known to not support MSI.
+The PCI stack provides 3 possible levels of MSI disabling:
+* on a single device
+* on all devices behind a specific bridge
+* globally
+
+6.1. Disabling MSI on a single device
+
+Under some circumstances, it might be required to disable MSI on a
+single device, It may be achived by either not calling pci_enable_msi()
+or all, or setting the pci_dev->no_msi flag before (most of the time
+in a quirk).
+
+6.2. Disabling MSI below a bridge
+
+The vast majority of MSI quirks are required by PCI bridges not
+being able to route MSI between busses. In this case, MSI have to be
+disabled on all devices behind this bridge. It is achieves by setting
+the PCI_BUS_FLAGS_NO_MSI flag in the pci_bus->bus_flags of the bridge
+subordinate bus. There is no need to set the same flag on bridges that
+are below the broken brigde. When pci_enable_msi() is called to enable
+MSI on a device, pci_msi_supported() takes care of checking the NO_MSI
+flag in all parent busses of the device.
+
+Some bridges actually support dynamic MSI support enabling/disabling
+by changing some bits in their PCI configuration space (especially
+the Hypertransport chipsets such as the nVidia nForce and Serverworks
+HT2000). It may then be required to update the NO_MSI flag on the
+corresponding devices in the sysfs hierarchy. To enable MSI support
+on device "0000:00:0e", do:
+
+ echo 1 > /sys/bus/pci/devices/0000:00:0e/msi_bus
+
+To disable MSI support, echo 0 instead of 1. Note that it should be
+used with caution since changing this value might break interrupts.
+
+6.3. Disabling MSI globally
+
+Some extreme cases may require to disable MSI globally on the system.
+For now, the only known case is a Serverworks PCI-X chipsets (MSI are
+not supported on several busses that are not all connected to the
+chipset in the Linux PCI hierarchy). In the vast majority of other
+cases, disabling only behind a specific bridge is enough.
+
+For debugging purpose, the user may also pass pci=nomsi on the kernel
+command-line to explicitly disable MSI globally. But, once the appro-
+priate quirks are added to the kernel, this option should not be
+required anymore.
+
+6.4. Finding why MSI cannot be enabled on a device
+
+Assuming that MSI are not enabled on a device, you should look at
+dmesg to find messages that quirks may output when disabling MSI
+on some devices, some bridges or even globally.
+Then, lspci -t gives the list of bridges above a device. Reading
+/sys/bus/pci/devices/0000:00:0e/msi_bus will tell you whether MSI
+are enabled (1) or disabled (0). In 0 is found in a single bridge
+msi_bus file above the device, MSI cannot be enabled.

Under each directory you would find an "online" file which is the control
file to logically online/offline a processor.
Q: Does hot-add/hot-remove refer to physical add/remove of cpus?
A: The usage of hot-add/remove may not be very consistently used in the code.
-CONFIG_CPU_HOTPLUG enables logical online/offline capability in the kernel.
+CONFIG_HOTPLUG_CPU enables logical online/offline capability in the kernel.
To support physical addition/removal, one would need some BIOS hooks and
the platform should have something like an attention button in PCI hotplug.
CONFIG_ACPI_HOTPLUG_CPU enables ACPI support for physical add/remove of CPUs.
Q: How do i logically offline a CPU?
A: Do the following.

Q: Why cant i remove CPU0 on some systems?
A: Some architectures may have some special dependency on a certain CPU.
departure, how to i arrange for proper notification?
A: This is what you would need in your kernel code to receive notifications.

+ #include <linux/cpu.h>
+ static int __cpuinit foobar_cpu_callback(struct notifier_block *nfb,
unsigned long action, void *hcpu)
{
unsigned int cpu = (unsigned long)hcpu;
A: Yes, CPU notifiers are called only when new CPUs are on-lined or offlined.
If you need to perform some action for each cpu already in the system, then
- for_each_online_cpu(i) {
+ for_each_online_cpu(i) {

-0. Status
----------
+0. Notes
+--------
+
+Driver updated for kernel 2.6.17.11. (Based on a patch for 2.6.11.4.)
-For now, this driver has only been tested on just one Linux-Box.
-This one is running a 2.4.18 kernel with usb-uhci on an amd athlon 600.
+The number of buttons/axes reported varies based on 3 things:
+- if you are using a known controller
+- if you are using a known dance pad
+- if using an unknown device (one not listed below), what you set in the
+ module configuration for "Map D-PAD to buttons rather than axes for unknown
+ pads" (module option dpad_to_buttons)
-The jstest-program from joystick-1.2.15 (jstest-version 2.1.0) reports
-8 axes and 10 buttons.
+If you set dpad_to_buttons to 0 and you are using an unknown device (one
+not listed below), the driver will map the directional pad to axes (X/Y),
+if you said N it will map the d-pad to buttons, which is needed for dance
+style games to function correctly. The default is Y.
+
+dpad_to_buttons has no effect for known pads.
+
+0.1 Normal Controllers
+----------------------
+With a normal controller, the directional pad is mapped to its own X/Y axes.
+The jstest-program from joystick-1.2.15 (jstest-version 2.1.0) will report 8
+axes and 10 buttons.

is some limitation of jstest, since the input device setup should be fine. I
didn't have a look at jstest itself yet).
play first person shooters with a pad. Your mileage may vary.
+0.2 Xbox Dance Pads
+-------------------
+When using a known dance pad, jstest will report 6 axes and 14 buttons.
+
+For dance style pads (like the redoctane pad) several changes
+have been made. The old driver would map the d-pad to axes, resulting
+in the driver being unable to report when the user was pressing both
+left+right or up+down, making DDR style games unplayable.
+
+Known dance pads automatically map the d-pad to buttons and will work
+correctly out of the box.
+
+If your dance pad is recognized by the driver but is using axes instead
+of buttons, see section 0.3 - Unknown Controllers
+
+I've tested this with Stepmania, and it works quite well.
+
+
+0.3 Unkown Controllers
+----------------------
+If you have an unkown xbox controller, it should work just fine with
+the default settings.
+
+HOWEVER if you have an unknown dance pad not listed below, it will not
+work UNLESS you set "dpad_to_buttons" to 1 in the module configuration.
+
+PLEASE if you have an unkown controller, email Dom <binary1230@yahoo.com> with
+a dump from /proc/bus/usb and a description of the pad (manufacturer, country,
+whether it is a dance pad or normal controller) so that we can add your pad
+to the list of supported devices, ensuring that it will work out of the
+box in the future.

machine check when some devices' config space
is read. But various workarounds are disabled
and some IOMMU drivers will not work.
+ bfsort Sort PCI devices into breadth-first order.
+ This sorting is done to get a device
+ order compatible with older (<= 2.4) kernels.
+ nobfsort Don't sort PCI devices into breadth-first order.

+The ccw_device must not be locked prior to calling read_dev_chars().
The function may be called enabled or disabled.
Usage Notes :
-Prior to call ccw_device_start() the device driver must assure disabled state,
-i.e. the I/O mask value in the PSW must be disabled. This can be accomplished
-by calling local_save_flags( flags). The current PSW flags are preserved and
-can be restored by local_irq_restore( flags) at a later time.
-
-If the device driver violates this rule while running in a uni-processor
-environment an interrupt might be presented prior to the ccw_device_start()
-routine returning to the device driver main path. In this case we will end in a
-deadlock situation as the interrupt handler will try to obtain the irq
-lock the device driver still owns (see below) !
-
-The driver must assure to hold the device specific lock. This can be
-accomplished by
-
-(i) spin_lock(get_ccwdev_lock(cdev)), or
-(ii) spin_lock_irqsave(get_ccwdev_lock(cdev), flags)
-
-Option (i) should be used if the calling routine is running disabled for
-I/O interrupts (see above) already. Option (ii) obtains the device gate und
-puts the CPU into I/O disabled state by preserving the current PSW flags.

+ * msi-laptop.c - MSI S270 laptop support. This laptop is sold under
+ * various brands, including "Cytron/TCM/Medion/Tchibo MD96100".
+ *
+ * This driver exports a few files in /sys/devices/platform/msi-laptop-pf/:
+ *
+ * lcd_level - Screen brightness: contains a single integer in the
+ * range 0..8. (rw)
+ *
+ * auto_brightness - Enable automatic brightness control: contains
+ * either 0 or 1. If set to 1 the hardware adjusts the screen
+ * brightness automatically when the power cord is
+ * plugged/unplugged. (rw)
+ *
+ * wlan - WLAN subsystem enabled: contains either 0 or 1. (ro)
+ *
+ * bluetooth - Bluetooth subsystem enabled: contains either 0 or 1
+ * Please note that this file is constantly 0 if no Bluetooth
+ * hardware is available. (ro)
+ *
+ * In addition to these platform device attributes the driver
+ * registers itself in the Linux backlight control subsystem and is
+ * available to userspace under /sys/class/backlight/msi-laptop-bl/.
+ *
+ * This driver might work on other laptops produced by MSI. If you
+ * want to try it you can pass force=1 as argument to the module which
+ * will force it to load even when the DMI data doesn't identify the
