2008-05-05kgdb: 1000 loops for the single step test in kgdbtsJason Wessel
The single step test is not terribly costly and it should be able to pass at 1000 loops successfully in under 1 second. A non-kgdb timing regression was found using this test, but it did not occur frequently because by default the test was only executed a single time. This patch changes the default for the single step test to 1000 iterations and allows for individual configuration of the single step test to further exercise the kgdb subsystem when needed.

2008-04-29ACPI: thinkpad-acpi: claim tpacpi as an official short handle (v1.1)Henrique de Moraes Holschuh
Unfortunately, a lot of stuff in the kernel has size limitations, so "thinkpad-acpi" ends up eating up too much real estate. We were using "tpacpi" in symbols already, but this shorthand was not visible to userland. Document that the driver will use tpacpi as a short hand where necessary, and use it to name the kernel thread for NVRAM polling (now named "ktpacpi_nvramd"). Also, register a module alias with the shorthand. One can refer to the module using the shorthand name.

2008-04-29ACPI: thinkpad-acpi: fix brightness dimming control bugHenrique de Moraes Holschuh
ibm-acpi and thinkpad-acpi did not know about bit 5 of the EC backlight level control register (EC 0x31), so it was always forced to zero on any writes. This would disable the BIOS option to *not* use a dimmer backlight level scale while on battery, and who knows what else (there are two other control bits of unknown function). Bit 5 controls the "reduce backlight levels when on battery" optional functionality (active low). Bits 6 and 7 are better left alone as well, instead of being forced to zero.

2008-04-29ACPI: thinkpad-acpi: rate-limit CMOS/EC unsynced error messagesHenrique de Moraes Holschuh
If userspace applications mess with the CMOS NVRAM, or something causes both the ACPI firmware and thinkpad-acpi to try to change the brightness at the same time, it is possible to have the CMOS and EC registers for the current brightness go out of sync. Should that happen, thinkpad-acpi could be really obnoxious when using a brightness_mode of 3 (both EC and CMOS). Instead of complaining a massive number of times, make sure to complain only once until EC and CMOS are back in sync.

2008-04-29ACPI: thinkpad-acpi: warn once about weird hotkey masksHenrique de Moraes Holschuh
thinkpad-acpi knows for a while now how to best program the hotkeys by default, and always enable them by default. Unfortunately, this information has not filtered down everywhere it needs to, yet. Notably, old ibm-acpi documentation and most "thinkpad setup guides" will have wrong information on this area. Warn the local admin once whenever any of the following patterns are met: 1. Attempts to set hotkey mask to 0xffff (artifact from docs and config for the old ibm-acpi driver and behaviour). This mask makes no real-world sense; 2. Attempts to set hotkey mask to 0xffffffff, which means the user is trying to just have "everything work" without even reading the documentation, or that we need to get a bug report, because there is a new thinkpad out there with new exciting hot keys :-) 3. Attempts to set hotkey mask to 0xffffff, which is almost never the correct way to set up volume and brightness event reporting (and with the current state-of-the-art, it is known to never be right way to do it). The driver will perform any and all requested operations, though, regardless of any warnings. I hope these warnings can be removed one or two years from now.

2008-04-29ACPI: thinkpad-acpi: BIOS backlight mode helper (v2.1)Henrique de Moraes Holschuh
Lenovo ThinkPads with generic ACPI backlight level control can be easily set to react to keyboard brightness key presses in a more predictable way than what they do when in "DOS / bootloader" mode after Linux brings up the ACPI interface. The switch to the ACPI backlight mode in the firmware is designed to be safe to use only as an one way trapdoor. One is not to force the firmware to switch back to "DOS/bootloader" mode except by rebooting. The mode switch itself is performed by calling any of the ACPI _BCL methods at least once. When in ACPI mode, the backlight firmware just issues (standard) events for the brightness up/down hot key presses along with the non-standard HKEY events which thinkpad-acpi traps, and doesn't touch the hardware. thinkpad-acpi will: 1. Place the ThinkPad firmware in ACPI backlight control mode if one is available 2. Suppress HKEY backlight change notifications by default to avoid double-reporting when ACPI video is loaded when the ThinkPad is in ACPI backlight control mode 3. Urge the user to load the ACPI video driver The user is free to use either the ACPI video driver to get the brightness key events, or to override the thinkpad-acpi default hotkey mask to get them from thinkpad-acpi as well (this will result in duplicate events if ACPI video is loaded, so let's hope distros won't screw this up). Provided userspace is sane, all should work (and *keep* working), which is more that can be said about the non-ACPI mode of the new Lenovo ThinkPad BIOSes when coupled to current userspace and X.org drivers. Full guidelines for backlight hot key reporting and use of the thinkpad-acpi backlight interface have been added to the documentation.

* git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/driver-2.6: (36 commits) SCSI: convert struct class_device to struct device DRM: remove unused dev_class IB: rename "dev" to "srp_dev" in srp_host structure IB: convert struct class_device to struct device memstick: convert struct class_device to struct device driver core: replace remaining __FUNCTION__ occurrences sysfs: refill attribute buffer when reading from offset 0 PM: Remove destroy_suspended_device() Firmware: add iSCSI iBFT Support PM: Remove legacy PM (fix) Kobject: Replace list_for_each() with list_for_each_entry(). SYSFS: Explicitly include required header file slab.h. Driver core: make device_is_registered() work for class devices PM: Convert wakeup flag accessors to inline functions PM: Make wakeup flags available whenever CONFIG_PM is set PM: Fix misuse of wakeup flag accessors in serial core Driver core: Call device_pm_add() after bus_add_device() in device_add() PM: Handle device registrations during suspend/resume block: send disk "change" event for rescan_partitions() sysdev: detect multiple driver registrations ... Fixed trivial conflict in include/linux/memory.h due to semaphore header file change (made irrelevant by the change to mutex).

2008-04-17kgdb: allow static kgdbts boot configurationJason Wessel
This patch adds in the ability to compile the kgdb internal test string into the kernel so as to run the tests at boot without changing the kernel boot arguments. This patch also changes all the error paths to invoke WARN_ON(1) which will emit the line number of the file and dump the kernel stack when an error occurs. You can disable the tests in a kernel that is built this way using "kgdbts=" Signed-off-by: Jason Wessel <jason.wessel@windriver.com> Signed-off-by: Ingo Molnar <mingo@elte.hu>
2008-04-17kgdb: add kgdb internal test suiteJason Wessel
This patch adds regression tests for testing the kgdb core and arch specific implementation. The kgdb test suite is designed to be built into the kernel and not as a module because it uses a number of low level kernel and kgdb primitives which should not be exported externally. The kgdb test suite is designed as a KGDB I/O module which simulates the communications that a debugger would have with kgdb. The tests are broken up in to a line by line and referenced here as a "get" which is kgdb requesting input and "put" which is kgdb sending a response. The kgdb suite can be invoked from the kernel command line arguments system or executed dynamically at run time. The test suite uses the variable "kgdbts" to obtain the information about which tests to run and to configure the verbosity level. The following are the various characters you can use with the kgdbts= line: When using the "kgdbts=" you only choose one of the following core test types: A = Run all the core tests silently V1 = Run all the core tests with minimal output V2 = Run all the core tests in debug mode You can also specify optional tests: N## = Go to sleep with interrupts of for ## seconds to test the HW NMI watchdog F## = Break at do_fork for ## iterations S## = Break at sys_open for ## iterations NOTE: that the do_fork and sys_open tests are mutually exclusive. To invoke the kgdb test suite from boot you use a kernel start argument as follows: kgdbts=V1 kgdbwait Or if you wanted to perform the NMI test for 6 seconds and do_fork test for 100 forks, you could use: kgdbts=V1N6F100 kgdbwait The test suite can also be invoked at run time with: echo kgdbts=V1N6F100 > /sys/module/kgdbts/parameters/kgdbts Or as another example: echo kgdbts=V2 > /sys/module/kgdbts/parameters/kgdbts When developing a new kgdb arch specific implementation or using these tests for the purpose of regression testing, several invocations are required. 1) Boot with the test suite enabled by using the kernel arguments "kgdbts=V1F100 kgdbwait" ## If kgdb arch specific implementation has NMI use "kgdbts=V1N6F100 2) After the system boot run the basic test. echo kgdbts=V1 > /sys/module/kgdbts/parameters/kgdbts 3) Run the concurrency tests. It is best to use n+1 while loops where n is the number of cpus you have in your system. The example below uses only two loops. ## This tests break points on sys_open while [ 1 ] ; do find / > /dev/null 2>&1 ; done & while [ 1 ] ; do find / > /dev/null 2>&1 ; done & echo kgdbts=V1S10000 > /sys/module/kgdbts/parameters/kgdbts fg # and hit control-c fg # and hit control-c ## This tests break points on do_fork while [ 1 ] ; do date > /dev/null ; done & while [ 1 ] ; do date > /dev/null ; done & echo kgdbts=V1F1000 > /sys/module/kgdbts/parameters/kgdbts fg # and hit control-c Signed-off-by: Jason Wessel <jason.wessel@windriver.com> Signed-off-by: Ingo Molnar <mingo@elte.hu>
