2010-11-23agp: kill agp_rebind_memoryDaniel Vetter1-1/+0
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 Vetter1-1/+0
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 Airlie1-1/+0
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>
2009-09-27const: mark struct vm_struct_operationsAlexey Dobriyan1-1/+1
* mark struct vm_area_struct::vm_ops as const * mark vm_ops in AGP code But leave TTM code alone, something is fishy there with global vm_ops being used. Signed-off-by: Alexey Dobriyan <adobriyan@gmail.com> Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>

2009-08-03agp: Add generic support for graphics dma remappingZhenyu Wang1-1/+5
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 Airlie1-1/+1
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 Packard1-0/+5
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 Airlie1-0/+1
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>
2007-02-04[AGPGART] Allow drm-populated agp memory typesThomas Hellstrom1-0/+5
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.

2005-04-17Linux-2.6.12-rc2Linus Torvalds1-0/+109
Initial git repository build. I'm not bothering with the full history, even though we have it. We can create a separate "historical" git archive of that later if we want to, and in the meantime it's about 3.2GB when imported into git - space that would just make the early git days unnecessarily complicated, when we don't have a lot of good infrastructure for it. Let it rip!
