Its only user, intel-gtt.c is now gone. Cc: Dave Airlie <airlied@gmail.com> Signed-off-by: Daniel Vetter <daniel.vetter@ffwll.ch> Signed-off-by: Chris Wilson <chris@chris-wilson.co.uk>
2010-11-23agp: kill agp_flush_chipset and corresponding ioctlDaniel Vetter
The intel drm calls the chipset functions now directly. Userspace never called the corresponding ioctl, hence it can be killed, too. Cc: Dave Airlie <airlied@gmail.com> Signed-off-by: Daniel Vetter <daniel.vetter@ffwll.ch> Signed-off-by: Chris Wilson <chris@chris-wilson.co.uk>
2010-06-15agp: drop vmalloc flag.Dave Airlie
Since the code that was too ugly to live is upstream, we can use it now, instead of rolling our own. Signed-off-by: Dave Airlie <airlied@redhat.com>

2009-08-03agp: Add generic support for graphics dma remappingZhenyu Wang
New driver hooks for support graphics memory dma remapping are introduced in this patch. It makes generic code can tell if current device needs dma remapping, then call driver provided interfaces for mapping and unmapping. Change has also been made to handle scratch_page in remapping case. Signed-off-by: Zhenyu Wang <zhenyu.z.wang@intel.com> Signed-off-by: David Woodhouse <David.Woodhouse@intel.com>
2009-06-19agp: switch AGP to use page array instead of unsigned long arrayDave Airlie
This switches AGP to use an array of pages for tracking the pages allocated to the GART. This should enable GEM on PAE to work a lot better as we can pass highmem pages to the PAT code and it will do the right thing with them. Signed-off-by: Dave Airlie <airlied@redhat.com>
2008-08-12intel/agp: rewrite GTT on resumeKeith Packard
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.

2008-02-05agp: add chipset flushing support to AGP interfaceDave Airlie
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 <airlied@redhat.com>
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.

2005-02-23[AGPGART] allow multiple backends to be initialized.Dave Jones
From: Michael Werner <werner@mrcoffee.engr.sgi.com> 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 <Brice.Goglin@ens-lyon.fr> 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 <werner@sgi.com> add bridge assignment missed in agp_allocate_memory From: Andi Kleen <ak@suse.de> Here's the correct fix. agp_bridge is defined in drivers/char/agp/agp.h.

2003-01-02[AGP] Move the VIA KT400 to its own driver.Dave Jones
Right now its the only VIA AGP 3.0 chipset. At some point in time it may become via-agp3.c, but until then its cleaner to seperate this from the VIA AGP 2.0 driver. The 2.0 driver will still work on a KT400 with a 2.0 compliant graphic card present. If the 2.0 driver finds the bridge in 3.0 mode, it aborts. Likewise, the 3.0 driver will abort if the bridge is in 2.0 mode. Confused yet?

2002-09-26[PATCH] Hammer aperture driver for 2.5.38Andi Kleen
Add an AGP driver for the AGP aperture in the northbridge of the AMD Hammer. The AGP driver works for both 32bit and 64bit kernels. It also adds some hooks to the AGP driver to allow the x86-64 GART based IOMMU code to share the aperture with AGP. The hooks are intentionally kept minimalistic. In addition it needs some Config.in hackery, because AGP cannot be modular in this case, because the IOMMU needs to control its startup and it runs early when PCI is initialized. The original AGP driver was done by Dave Jones, I added the IOMMU support.
