intel/agp: rewrite GTT on resume

2008-08-12T00:13:38Z

On my Intel chipset (965GM), the GTT is entirely erased across suspend/resume. This patch simply re-plays the current mapping at resume time to restore the table.=20 I noticed this once I started relying on persistent GTT mappings across VT switch in our GEM work -- the old X server and DRM code carefully unbind all memory from the GTT on VT switch, but GEM does not bother. I placed the list management and rewrite code in the generic layer on the assumption that it will be needed on other hardware, but I did not add the rewrite call to anything other than the Intel resume function. Keep a list of current GATT mappings. At resume time, rewrite them into the GATT. This is needed on Intel (at least) as the entire GATT is cleared across suspend/resume.

agp: add chipset flushing support to AGP interface

2008-02-05T04:33:32Z

This bumps the AGP interface to 0.103. Certain Intel chipsets contains a global write buffer, and this can require flushing from the drm or X.org to make sure all data has hit RAM before initiating a GPU transfer, due to a lack of coherency with the integrated graphics device and this buffer. This just adds generic support to the AGP interfaces, a follow-on patch will add support to the Intel driver to use this interface. Signed-off-by: Dave Airlie

[AGPGART] Allow drm-populated agp memory types

2007-02-03T22:16:24Z

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.

[AGPGART] allow multiple backends to be initialized.

2005-02-23T13:12:13Z

From: Michael Werner This patch adds support for initializing and addressing multiple AGP bridges using the agpgart driver. In particular, it extends agp_acquire and agp_allocate_memory so that different bridges can be acquired and memory allocated within a specific AGP aperature. From: Brice Goglin It seems that memsetting the whole bridge structure to 0 (instead of juste the agp_in_use field) fixes Benoit's problem too. No idea which field was responsible for this. New patch attached. From: Mike Werner add bridge assignment missed in agp_allocate_memory From: Andi Kleen Here's the correct fix. agp_bridge is defined in drivers/char/agp/agp.h. It's a bit ugly though. Signed-off-by: Mike Werner Signed-off-by: Andi Kleen Signed-off-by: Andrew Morton Signed-off-by: Dave Jones
