| * [AGPGART] intel_agp: fix device probeWang Zhenyu2007-06-141-46/+51
| | | | | | | | | | | | | | | | | | | | | | 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.

| * [AGPGART] intel_agp: use table for device probeWang Zhenyu2007-06-061-202/+98
| | | | | | | | | | | | | | | | | | | | | | | | Fixed issues noted by Christoph Hellwig, and I changed device table scan a bit to allow the case that some models of graphics chips may have same host bridge type. This type of chip will be added in the future. This patch cleans up device probe function. Eric Anholt was the original author.

* | Detach sched.h from mm.hAlexey Dobriyan2007-05-212-0/+2
|/ | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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%).

* [AGPGART] Fix wrong ID in via-agp.cGabriel Mansi2007-05-131-3/+3
| | | | | | | | | | | | | | | there is a wrong id in drivers/char/agp/via-agp.c #define PCI_DEVICE_ID_VIA_CX700 0x8324 It must be 0x0324 Notice that PCI_DEVICE_ID_VIA_CX700 is also used in drivers/i2c/busses/i2c-viapro.c and drivers/ide/pci/via82cxxx.c So, I think that constant must be renamed to avoid conflicting.

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.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

* | [AGPGART] Remove unnecessary flushes when inserting and removing pages.Thomas Hellstrom2006-12-222-23/+50
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch is to speed up flipping of pages in and out of the AGP aperture as needed by the new drm memory manager. A number of global cache flushes are removed as well as some PCI posting flushes. The following guidelines have been used: 1) Memory that is only mapped uncached and that has been subject to a global cache flush after the mapping was changed to uncached does not need any more cache flushes. Neither before binding to the aperture nor after unbinding. 2) Only do one PCI posting flush after a sequence of writes modifying page entries in the GATT.
