* ACPI: add dynamic_debug supportBjørn Mork2014-05-261-12/+52
| | | | | | | | | | | | | | | | | | | Commit 1a699476e258 ("ACPI / hotplug / PCI: Hotplug notifications from acpi_bus_notify()") added debug messages for a few common events. These debug messages are unconditionally enabled if CONFIG_DYNAMIC_DEBUG is defined, contrary to the documented meaning, making the ACPI system spew lots of unwanted noise on any kernel with dynamic debugging. The bug was introduced by commit fbfddae69657 ("ACPI: Add acpi_handle_<level>() interfaces"), which added the CONFIG_DYNAMIC_DEBUG dependency without respecting its meaning. Fix by adding real support for dynamic_debug. Fixes: fbfddae69657 ("ACPI: Add acpi_handle_<level>() interfaces") Signed-off-by: Bjørn Mork <bjorn@mork.no> Signed-off-by: Rafael J.

| * ACPI: introduce helper interfaces for _DSM methodJiang Liu2014-01-051-0/+97
| | | | | | | | | | | | | | | | | | | | | | | | | | There are several drivers making use of ACPI _DSM method to detect and invoke device specific methods. Currently every driver has implemented its private version to support ACPI _DSM method. So this patch introduces three helper functions to support ACPI _DSM method, which will be used to replace open-coded versions. It helps to simplify code and improve code readability.

* | ACPI: Clean up inclusions of ACPI header filesLv Zheng2013-12-071-2/+0
|/ | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Replace direct inclusions of <acpi/acpi.h>, <acpi/acpi_bus.h> and <acpi/acpi_drivers.h>, which are incorrect, with <linux/acpi.h> inclusions and remove some inclusions of those files that aren't necessary. First of all, <acpi/acpi.h>, <acpi/acpi_bus.h> and <acpi/acpi_drivers.h> should not be included directly from any files that are built for CONFIG_ACPI unset, because that generally leads to build warnings about undefined symbols in !CONFIG_ACPI builds. For CONFIG_ACPI set, <linux/acpi.h> includes those files and for CONFIG_ACPI unset it provides stub ACPI symbols to be used in that case. Second, there are ordering dependencies between those files that always have to be met. Namely, it is required that <acpi/acpi_bus.h> be included prior to <acpi/acpi_drivers.h> so that the acpi_pci_root declarations the latter depends on are always there. And <acpi/acpi.h> which provides basic ACPICA type declarations should always be included prior to any other ACPI headers in CONFIG_ACPI builds. That also is taken care of including <linux/acpi.h> as appropriate.

* ACPI: Add acpi_handle_<level>() interfacesToshi Kani2012-11-211-0/+38
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch introduces acpi_handle_<level>(), where <level> is a kernel message level such as err/warn/info, to support improved logging messages for ACPI, esp. hot-plug operations. acpi_handle_<level>() appends "ACPI" prefix and ACPI object path to the messages. This improves diagnosis of hotplug operations since an error message in a log file identifies an object that caused an issue. This interface acquires the global namespace mutex to obtain an object path. In interrupt context, it shows the object path as <n/a>. acpi_handle_<level>() takes acpi_handle as an argument, which is passed to ACPI hotplug notify handlers from the ACPICA. Therefore, it is always available unlike other kernel objects, such as device. For example: acpi_handle_err(handle, "Device don't exist, dropping EJECT\n"); logs an error message like this at KERN_ERR. ACPI: \_SB_.SCK4.CPU4: Device don't exist, dropping EJECT ACPI hot-plug drivers can use acpi_handle_<level>() when they need to identify a target ACPI object path in their messages, such as error cases. The usage model is similar to dev_<level>(). acpi_handle_<level>() can be used when a device is not created or is invalid during hot-plug operations. ACPI object path is also consistent on the platform, unlike device name that gets incremented over hotplug operations. ACPI drivers should use dev_<level>() when a device object is valid. Device name provides more user friendly information, and avoids acquiring the global ACPI namespace mutex. ACPI drivers also continue to use pr_<level>() when they do not need to specify device information, such as boot-up messages. Note: ACPI_[WARNING|INFO|ERROR]() are intended for the ACPICA and are not associated with the kernel message level.

* ACPI: Add an interface to evaluate _OSTToshi Kani2012-06-041-0/+42
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Added acpi_evaluate_hotplug_opt(). All ACPI hotplug handlers must call this function when evaluating _OST for hotplug operations. If the platform does not support _OST, this function returns AE_NOT_FOUND and has no effect on the platform. ACPI_HOTPLUG_OST is defined when all relevant ACPI hotplug operations, such as CPU, memory and container hotplug, are enabled. This assures consistent behavior among the hotplug operations with regarding the _OST support. When ACPI_HOTPLUG_OST is not defined, this function is a no-op. ACPI PCI hotplug is not enhanced to support _OST at this time since it is a legacy method being replaced by PCIe native hotplug. _OST support for ACPI PCI hotplug may be added in future if necessary. Some platforms may require the OS to support _OST in order to support ACPI hotplug operations. For example, if a platform has the management console where user can request a hotplug operation from, this _OST support would be required for the management console to show the result of the hotplug request to user. Added macro definitions of _OST source events and status codes. Also renamed OSC_SB_CPUHP_OST_SUPPORT to OSC_SB_HOTPLUG_OST_SUPPORT since this _OSC bit is not specific to CPU hotplug. This bit is defined in Table 6-147 of ACPI 5.0 as follows. Bits: 3 Field Name: Insertion / Ejection _OST Processing Support Definition: This bit is set if OSPM will evaluate the _OST object defined under a device when processing insertion and ejection source event codes.

* include cleanup: Update gfp.h and slab.h includes to prepare for breaking ↵Tejun Heo2010-03-301-0/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

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!
