2010-08-15ACPI: remove deprecated ACPI procfs I/FZhang Rui
Rmove deprecated ACPI procfs I/F, including /proc/acpi/debug_layer /proc/acpi/debug_level /proc/acpi/info /proc/acpi/dsdt /proc/acpi/fadt /proc/acpi/sleep because the sysfs I/F is already available and has been working well for years.

2010-08-14ACPI: introduce drivers/acpi/debugfs.cZhang Rui
Introduce drivers/acpi/debugfs.c. Code for ACPI debugfs I/F, i.e. /sys/kernel/debug/acpi/custom_method, is moved to this file. And make ACPI debugfs always built in, even if CONFIG_ACPI_DEBUG is cleared. BTW:this adds about 400bytes code to ACPI, when CONFIG_ACPI_DEBUG is cleared.

2010-03-30include cleanup: Update gfp.h and slab.h includes to prepare for breaking ↵Tejun Heo
implicit slab.h inclusion from percpu.h percpu.h is included by sched.h and module.h and thus ends up being included when building most .c files. percpu.h includes slab.h which in turn includes gfp.h making everything defined by the two files universally available and complicating inclusion dependencies. percpu.h -> slab.h dependency is about to be removed. Prepare for this change by updating users of gfp and slab facilities include those headers directly instead of assuming availability. As this conversion needs to touch large number of source files, the following script is used as the basis of conversion. http://userweb.kernel.org/~tj/misc/slabh-sweep.py The script does the followings. * Scan files for gfp and slab usages and update includes such that only the necessary includes are there. ie. if only gfp is used, gfp.h, if slab is used, slab.h. * When the script inserts a new include, it looks at the include blocks and try to put the new include such that its order conforms to its surrounding. It's put in the include block which contains core kernel includes, in the same order that the rest are ordered - alphabetical, Christmas tree, rev-Xmas-tree or at the end if there doesn't seem to be any matching order. * If the script can't find a place to put a new include (mostly because the file doesn't have fitting include block), it prints out an error message indicating which .h file needs to be added to the file. The conversion was done in the following steps. 1. The initial automatic conversion of all .c files updated slightly over 4000 files, deleting around 700 includes and adding ~480 gfp.h and ~3000 slab.h inclusions. The script emitted errors for ~400 files. 2. Each error was manually checked. Some didn't need the inclusion, some needed manual addition while adding it to implementation .h or embedding .c file was more appropriate for others. This step added inclusions to around 150 files. 3. The script was run again and the output was compared to the edits from #2 to make sure no file was left behind. 4. Several build tests were done and a couple of problems were fixed. e.g. lib/decompress_*.c used malloc/free() wrappers around slab APIs requiring slab.h to be added manually. 5. The script was run on all .h files but without automatically editing them as sprinkling gfp.h and slab.h inclusions around .h files could easily lead to inclusion dependency hell. Most gfp.h inclusion directives were ignored as stuff from gfp.h was usually wildly available and often used in preprocessor macros. Each slab.h inclusion directive was examined and added manually as necessary. 6. percpu.h was updated not to include slab.h. 7. Build test were done on the following configurations and failures were fixed. CONFIG_GCOV_KERNEL was turned off for all tests (as my distributed build env didn't work with gcov compiles) and a few more options had to be turned off depending on archs to make things build (like ipr on powerpc/64 which failed due to missing writeq). * x86 and x86_64 UP and SMP allmodconfig and a custom test config. * powerpc and powerpc64 SMP allmodconfig * sparc and sparc64 SMP allmodconfig * ia64 SMP allmodconfig * s390 SMP allmodconfig * alpha SMP allmodconfig * um on x86_64 SMP allmodconfig 8. percpu.h modifications were reverted so that it could be applied as a separate patch and serve as bisection point. Given the fact that I had only a couple of failures from tests on step 6, I'm fairly confident about the coverage of this conversion patch. If there is a breakage, it's likely to be something in one of the arch headers which should be easily discoverable easily on most builds of the specific arch.

2009-12-11ACPI: support customizing ACPI control methods at runtimeZhang Rui
Introduce a new debugfs I/F (/sys/kernel/debug/acpi/custom_method) for ACPI, which can be used to customize the ACPI control methods at runtime. We can use this to debug the AML code level bugs instead of overriding the whole DSDT table, without rebuilding/rebooting kernel any more. Detailed description about how to use this debugfs I/F is stated in Documentation/acpi/method-customizing.txt Signed-off-by: Zhang Rui <rui.zhang@intel.com> Signed-off-by: Len Brown <len.brown@intel.com>

2009-04-02ACPI: simplify module_param namespaceRusty Russell
Impact: cleanup Rather than overriding MODULE_PARAM_PREFIX, build via acpi.o so KBUILD_MODNAME is set to "acpi". This is the logical way to do it, even though acpi cannot be a module due to these config options being bool. Those parts of ACPI which can be modular are not built into the acpi "module".

2009-03-27ACPI: call acpi_debug_init() explicitly rather than as initcallBjorn Helgaas
This patch makes acpi_init() call acpi_debug_init() directly. Previously, both were subsys_initcalls. acpi_debug_init() must happen after acpi_init(), and it's better to call it explicitly rather than rely on link ordering.

2007-11-19ACPI: add control method tracing supportZhang Rui
Add debug tracing support during certain AML method execution. Four more module parameters are created under /sys/module/acpi/parameters/: trace_method_name: the AML method name that user wants to trace trace_debug_layer: the temporary debug_layer used when tracing the method. Using 0xffffffff by default if it is 0. trace_debug_level: the temporary debug_level used when tracing the method. Using 0x00ffffff by default if it is 0. trace_state: The status of the tracing feature. "enabled" means this feature is enabled and the AML method is traced every time it's executed. "1" means this feature is enabled and the AML method will only be traced during the next execution. "disabled" means this feature is disabled. Users can enable/disable this debug tracing feature by "echo string > /sys/module/acpi/parameters/trace_state". "string" should be one of "enable", "disable" and "1". http://bugzilla.kernel.org/show_bug.cgi?id=6629 Signed-off-by: Zhang Rui <rui.zhang@intel.com> Signed-off-by: Len Brown <len.brown@intel.com>

2007-01-28ACPI: add ACPI debug attribute in sysfsZhang Rui
Add ACPI debug attributes in sysfs. /proc/acpi/debug_layer && debug_level are deprecated by /sys/module/acpi/parameters/debug_layer && debug_level. NOTE: The operations to them are quite the same. E.g. if you want to enable ACPI_DB_INFO, ACPI_DB_WARN, ACPI_DB_ERROR and disable the others, #echo 0x13 >/sys/module/acpi/parameters/debug_level is OK, and a boot option "acpi.debug_level = 0x13" also works.

Initial git repository build. I'm not bothering with the full history, even though we have it. We can create a separate "historical" git archive of that later if we want to, and in the meantime it's about 3.2GB when imported into git - space that would just make the early git days unnecessarily complicated, when we don't have a lot of good infrastructure for it. Let it rip!
