2009-06-19agp: add user mapping support to ATI AGP bridge.Dave Airlie1-4/+14
This should fix TTM/KMS on some of the original ATI IGP chipsets. (rs100/rs200) Signed-off-by: Dave Airlie <airlied@redhat.com>
2009-06-19drm/i915: enable GEM on PAE.Dave Airlie1-5/+0
In theory now that the AGP subsystem is using struct page, we should have on problems enabling GEM on PAE systems. Signed-off-by: Dave Airlie <airlied@redhat.com>
2009-06-19drm/radeon: fix unused variables warningDave Airlie1-2/+0
just remove i variable left over from previous code. Signed-off-by: Dave Airlie <airlied@redhat.com>
2009-06-19agp: switch AGP to use page array instead of unsigned long arrayDave Airlie21-146/+152
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>
2009-06-19agpgart: detected ALi M???? chipset with M1621Ondrej Zary1-1/+1

2009-06-19drm/radeon: command stream checker for r3xx-r5xx hardwareJerome Glisse7-65/+611
For security purpose we want to make sure the userspace process doesn't access memory beyond buffer it owns. To achieve this we need to check states the userspace program. For color buffer and zbuffer we check that the clipping register will discard access beyond buffers set as color or zbuffer. For vertex buffer we check that no vertex fetch will happen beyond buffer end. For texture we check various texture states (number of mipmap level, texture size, texture depth, ...) to compute the amount of memory the texture fetcher might access. The command stream checking impact the performances so far quick benchmark shows an average of 3% decrease in fps of various applications. It can be optimized a bit more by caching result of checking and thus avoid a full recheck if no states changed since last check. Note that this patch is still incomplete on checking side as it doesn't check 2d rendering states. Signed-off-by: Jerome Glisse <jglisse@redhat.com> Signed-off-by: Dave Airlie <airlied@redhat.com>

2009-06-19drm/radeon: Respect AGP cant_use_aperture flag.Michel Dänzer1-4/+4
Some AGP devices can't map the aperture, radeon needs to tell TTM this. Signed-off-by: Dave Airlie <airlied@redhat.com>

2009-06-19ttm: Return -ERESTART when a signal interrupts bo eviction.Thomas Hellstrom1-3/+6

2009-06-18drm: Remove memory debugging infrastructure.Eric Anholt41-884/+324
It hasn't been used in ages, and having the user tell your how much memory is being freed at free time is a recipe for disaster even if it was ever used. Signed-off-by: Eric Anholt <eric@anholt.net>
2009-06-18drm/i915: Clear fence register on tiling stride change.Chris Wilson3-17/+88
The fence register value also depends upon the stride of the object, so we need to clear the fence if that is changed as well. Signed-off-by: Chris Wilson <chris@chris-wilson.co.uk> [anholt: Added 8xx and 965 paths, and renamed the confusing i915_gem_object_tiling_ok function to i915_gem_object_fence_offset_ok] Signed-off-by: Eric Anholt <eric@anholt.net>
2009-06-18drm/i915: Install fence register for tiled scanout on i915Chris Wilson3-10/+21
With the work by Jesse Barnes to eliminate allocation of fences during execbuffer, it becomes possible to write to the scan-out buffer with it never acquiring a fence (simply by only ever writing to the object using tiled GPU commands and never writing to it via the GTT). So for pre-i965 chipsets which require fenced access for tiled scan-out buffers, we need to obtain a fence register.

2009-06-17drm/i915: detach/attach get/put pages symmetryChris Wilson1-0/+4
After performing an operation over the page list for a buffer retrieved by i915_gem_object_get_pages() the pages need to be returned with i915_gem_object_put_pages(). This was not being observed for the phys objects which were thus leaking references to their backing pages.

2009-06-17drm/i915: Warn when inteldrmfb fails to restore its framebuffer configBen Gamari1-1/+5
While sifting through the inteldrmfb code trying to solve #22040 I found that the fb restore path doesn't check the return value of drm_crtc_helper_set_config(), which seems to have all sorts of potential failure modes.

2009-06-17kmemleak: Only use GFP_KERNEL|GFP_ATOMIC for the internal allocationsCatalin Marinas1-2/+5
Kmemleak allocates memory for pointer tracking and it tries to avoid using GFP_ATOMIC if the caller doesn't require it. However other gfp flags may be passed by the caller which aren't required by kmemleak. This patch filters the gfp flags so that only GFP_KERNEL | GFP_ATOMIC are used.
