* master.kernel.org:/pub/scm/linux/kernel/git/davej/agpgart: [AGPGART] Hand off AGP maintainence.
2007-07-11PCI: Change all drivers to use pci_device->revisionAuke Kok
Instead of all drivers reading pci config space to get the revision ID, they can now use the pci_device->revision member. This exposes some issues where drivers where reading a word or a dword for the revision number, and adding useless error-handling around the read. Some drivers even just read it for no purpose of all. In devices where the revision ID is being copied over and used in what appears to be the equivalent of hotpath, I have left the copy code and the cached copy as not to influence the driver's performance. Compile tested with make all{yes,mod}config on x86_64 and i386.

2007-07-09[AGPGART] Hand off AGP maintainence.Dave Jones
Most of the AGP changes recently have been done in lock-step with DRM updates, so it's probably easier to have airlied pushing AGP changes at the same time he does DRM updates. [Also remove my name from the boot messages. Cautionary tale to others: Never do this, when computers don't boot, people assume you're responsible even if 15 other subsystems initialised after yours. :-) ] Signed-off-by: Dave Jones <davej@redhat.com> Signed-off-by: Dave Airlie <airlied@linux.ie>
2007-06-21[AGPGART] intel_agp: don't load if no IGD and AGP portWang Zhenyu
After i915 chip, GMCH has no AGP port. Origin bridge driver in device table will try to access illegal regs like APBASE, APSIZE, etc. This may cause problem. So mark them as NULL in the table, we won't load if no IGD got detect and bridge has no AGP port. Signed-off-by: Wang Zhenyu <zhenyu.z.wang@intel.com> Signed-off-by: Dave Jones <davej@redhat.com>

2007-06-14[AGPGART] intel_agp: fix device probeWang Zhenyu
This patch trys to fix device probe in two cases. First we should correctly detect device if integrated graphics device is not enabled or exists, like an add-in card is plugged. Second on some type of intel GMCH, it might have multiple graphic chip models, like 945GME case, so we should be sure the detect works through the whole table.

2007-05-21Detach sched.h from mm.hAlexey Dobriyan
First thing mm.h does is including sched.h solely for can_do_mlock() inline function which has "current" dereference inside. By dealing with can_do_mlock() mm.h can be detached from sched.h which is good. See below, why. This patch a) removes unconditional inclusion of sched.h from mm.h b) makes can_do_mlock() normal function in mm/mlock.c c) exports can_do_mlock() to not break compilation d) adds sched.h inclusions back to files that were getting it indirectly. e) adds less bloated headers to some files (asm/signal.h, jiffies.h) that were getting them indirectly Net result is: a) mm.h users would get less code to open, read, preprocess, parse, ... if they don't need sched.h b) sched.h stops being dependency for significant number of files: on x86_64 allmodconfig touching sched.h results in recompile of 4083 files, after patch it's only 3744 (-8.3%). Cross-compile tested on all arm defconfigs, all mips defconfigs, all powerpc defconfigs, alpha alpha-up arm i386 i386-up i386-defconfig i386-allnoconfig ia64 ia64-up m68k mips parisc parisc-up powerpc powerpc-up s390 s390-up sparc sparc-up sparc64 sparc64-up um-x86_64 x86_64 x86_64-up x86_64-defconfig x86_64-allnoconfig as well as my two usual configs.

2007-04-26[AGPGART] prevent probe collision of sis-agp and amd64_agpOliver Neukum
For some vendor/id pairs the kernel will autoload both the sis-agp and the amd64_agp modules as the sis-agp module will load for all sis devices. This collision causes the bug reported in: http://bugzilla.novell.com/show_bug.cgi?id=248665 As currently sis_probe does its own matching, requesting the whole range gains nothing. The clean fix seems to me to leave the matching to the core and advertise only the devices actually supported. This patch does so.

2007-02-03[AGPGART] Allow drm-populated agp memory typesThomas Hellstrom
This patch allows drm to populate an agpgart structure with pages of its own. It's needed for the new drm memory manager which dynamically flips pages in and out of AGP. The patch modifies the generic functions as well as the intel agp driver. The intel drm driver is currently the only one supporting the new memory manager. Other agp drivers may need some minor fixing up once they have a corresponding memory manager enabled drm driver. AGP memory types >= AGP_USER_TYPES are not populated by the agpgart driver, but the drm is expected to do that, as well as taking care of cache- and tlb flushing when needed. It's not possible to request these types from user space using agpgart ioctls. The Intel driver also gets a new memory type for pages that can be bound cached to the intel GTT.

2006-12-22[AGPGART] fix detection of aperture size versus GTT size on G965Eric Anholt
On the G965, the GTT size may be larger than is required to cover the aperture. (In fact, on all hardware we've seen, the GTT is 512KB to the aperture's 256MB). A previous commit forced the aperture size to 512MB on G965 to match GTT, which would likely result in hangs at best if users tried to rely on agpgart's aperture size information. Instead, we use the resource length for the aperture size and the system's reported GTT size when available for the GTT size. Because the MSAC registers which had been read for aperture size detection on i9xx chips just cause a change in the resource size, we can use generic code for aperture detection on all i9xx.
