* include cleanup: Update gfp.h and slab.h includes to prepare for breaking ↵Tejun Heo2010-03-30
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

* ALSA: hda - Fix Oops at reloading beep devicesTakashi Iwai2009-12-27
| | | | | | | | | | | The recent change for supporting dynamic beep device allocation caused a problem resulting in Oops at reloading the driver. Also, it ignores the error from input device registration. This patch fixes the wrong check in snd_hda_detach_beep_device(), and returns an error when the input device registration fails properly.

* ALSA: hda - Fix beep_mode option valueTakashi Iwai2009-11-16
| | | | | | | | | | The beep_mode option value was wrongly defined: it must be 0 = off and 1 = on. Also, evaluate the beep_mode value at snd_hda_attach_beep_device() properly so that no device is created when beep_mode=0 is given. Signed-off-by: Takashi Iwai <tiwai@suse.de>
* ALSA: hda - add beep_mode module parameterJaroslav Kysela2009-11-16
| | | | | | | | | | | | | | The beep_mode parameter for snd-hda-intel module allows to choose among different digital beep device registation to the input layer. 0 = do not register to the input layer 1 = register to the input layer all time 2 = use "Beep Switch" control exported to user space mixer applications Also, introduce CONFIG_SND_HDA_INPUT_BEEP_MODE for default value.

| | | | | | | | | | | The massive register/unregister calls for input device layer might be overkill. Delay unregister call by one HZ as workaround.

* ALSA: hda_intel: Digital PC Beep - change behaviour for input layerJaroslav Kysela2009-11-16
| | | | | | | | | | | | | | | | Original implementation was keeping registered input device for SND_BEEP and SND_TONE events all time. This patch changes this behaviour: If digital PC Beep is turned off using universal control switch, the input device is unregistered. Explanation: The kd_mksound() send SND_BEEP and SND_TONE only to last registered device acceping those events. It means that the HDA Intel audio driver blocks also the internal PC Speaker device (pcspkr.c driver) even if the HDA Beep is muted. The user can easy disable all beeps using 'setterm -blength 0' or 'xset b off' command. Signed-off-by: Jaroslav Kysela <perex@perex.cz> Signed-off-by: Takashi Iwai <tiwai@suse.de>

| | | | | | | | | | | | | | | | | | | | | | | | In the beep tone calculation for IDT/STAC codecs, lower numbers correspond to higher frequencies and vice versa. The current code has this backwards, resulting in beep frequencies which are way too high (and sound bad on tinny laptop speakers, resulting in complaints).

* ALSA: hda - Fix digital beep tone calculationTakashi Iwai2009-05-19
| | | | | | | | | | | | | | | | The digital beep tone is calculated in two different ways depending on the codec chip. The standard one is using a divider, and another one is a linear tone for IDT/STAC codecs. Currently, only the latter type is used for all codecs, which resulted in a wrong tone pitch. This patch adds the calculation of the standard HD-audio type. Also clean-up the fields in hda_beep struct.

* ALSA: hda - Use own workqueueTakashi Iwai2009-01-12
| | | | | | | | | | | | | | snd-hda-intel driver used schedule_work() fot the delayed DMA pointer updates, but this has several potential problems: - it may block other eventsd works longer - it may deadlock when probing fails and flush_scheduled_work() is called during probe callback (as probe callback itself could be invoked from eventd) This patch adds an own workq for each driver instance to solve these problems.

* ALSA: hda - Don't export symbols when built-in kernelTakashi Iwai2008-11-28
| | | | | | | | | | | | The global functions in hda_codec.c and other core parts are only for HD-audio codec and controller drivers. When the HD-audio driver is built in kernel, all stuff have to be statically linked, thus we don't need any exports. This patch introduces a conditional macro to do export only when needed.

* ALSA: hda - Modularize HD-audio driverTakashi Iwai2008-11-27
| | | | | | | | | | | | | | | | | | | | | | | | Split the monolithc HD-audio driver into several pieces: - snd-hda-intel HD-audio PCI controller driver; loaded via udev - snd-hda-codec HD-audio codec bus driver - snd-hda-codec-* Specific HD-audio codec drivers When built as modules, snd-hda-codec (that is invoked by snd-hda-intel) looks up the codec vendor ID and loads the corresponding codec module automatically via request_module(). When built in a kernel, each codec drivers are statically hooked up before probing the PCI. This patch adds appropriate EXPORT_SYMBOL_GPL()'s and the module information for each driver, and driver-linking codes between codec-bus and codec drivers.
