2010-03-30include cleanup: Update gfp.h and slab.h includes to prepare for breaking ↵Tejun Heo64-3/+61
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.

2010-03-25drm/i915: Rename intel_output to intel_encoder.Eric Anholt11-663/+663
The intel_output naming is inherited from the UMS code, which had a structure of screen -> CRTC -> output. The DRM code has an additional notion of encoder/connector, so the structure is screen -> CRTC -> encoder -> connector. This is a useful structure for SDVO encoders which can support multiple connectors (each of which requires different programming in the one encoder and could be connected to different CRTCs), or for DVI-I, where multiple encoders feed into the connector for whether it's used for digital or analog. Most of our code is encoder-related, so transition it to talking about encoders before we start trying to distinguish connectors. This patch is produced by sed s/intel_output/intel_encoder/ over the driver. Signed-off-by: Eric Anholt <[email protected]>

2010-03-24PCI quirk: RS780/RS880: work around missing MSI initializationClemens Ladisch1-7/+1
AMD says in section 2.5.4 (GFX MSI Enable) of #43291 (AMD 780G Family Register Programming Requirements): The SBIOS must enable internal graphics MSI capability in GCCFG by setting the following: NBCFG.NB_CNTL.STRAP_MSI_ENABLE='1' Quite a few BIOS writers misinterpret this sentence and think that enabling MSI is an optional feature. However, clearing that bit just prevents delivery of MSI messages but does not remove the MSI PCI capabilities registers, and so leaves these devices unusable for any driver that attempts to use MSI. Setting that bit is not possible after the BIOS has locked down the configuration registers, so we have to manually disable MSI for the affected devices. This fixes the codec communication errors in the HDA driver when accessing the HDMI audio device, and allows us to get rid of the overcautious quirk in radeon_irq_kms.c.

I've been getting more and more quirk reports about this. It seems clear at this point that other OSes are not using this for determining whether the integrated panel should be turned on, and it is not reliable for doing so. Better to light up an unintended panel than to not light up the only usable output on the system. Signed-off-by: Eric Anholt <[email protected]> Acked-by: Jesse Barnes <[email protected]>
