2010-10-26drm/radeon/kms/evergreen: set the clear state to the blit stateAlex Deucher
The hw stores a default clear state for registers in the context range that can be initialized when the CP is set up. Set the blit state as the default clear state and use the CLEAR_STATE packet to load the blit state rather than loading it from an IB. This reduces overhead when doing bo moves using the 3D engine.

The vram map in the radeon memory controller needs to be >= the pci aperture size. Fixes: https://bugs.freedesktop.org/show_bug.cgi?id=28402 The problematic cards in the above bug have 64 MB of vram, but the pci aperture is 128 MB and the MC vram map was only 64 MB.

2010-10-26drm/radeon/r600: fix tiling issues in CS checker.Dave Airlie
The CS checker had some incorrect alignment requirements for 2D surfaces, this made rendering to mipmap levels that were 2D broken. Also the CB height was being worked out from the BO size, this doesn't work at all when rendering mipmap levels, instead we work out what height userspace wanted from slice max and use that to check it fits inside the BO, however the DDX send the wrong slice max for an unaligned buffer so we have to workaround for that even though its a userspace bug.

When changing VTs non-atomically the kernel works in conjunction with the Xserver in user space and receives the LUT information from the Xserver via a system call.

2010-10-06drm/radeon: Add function for display scanout position query.Mario Kleiner
radeon_get_crtc_scanoutpos() returns the current horizontal and vertical scanout position of a crtc. It also reports if the display scanout is currently inside the vblank area. hpos reports current horizontal pixel scanout position. vpos reports the current scanned out line as a value >= 0 in active scanout. If the scanout is inside vblank area, it reports a negative value, the number of scanlines until end of vblank aka start of active scanout, e.g., -3 == "At most 3 scanlines until end of vblank".

There were lots of places being inconsistent since handle count looked like a kref but it really wasn't.

2010-09-15drm/radeon/kms: only warn on mipmap size checks in r600 cs checker (v2)Alex Deucher
The texture base address registers are in units of 256 bytes. The original CS checker treated these offsets as bytes, so the original check was wrong. I fixed the units in a patch during the 2.6.36 cycle, but this ended up breaking some existing userspace (probably due to a bug in either userspace texture allocation or the drm texture mipmap checker). So for now, until we come up with a better fix, just warn if the mipmap size it too large. This will keep existing userspace working and it should be just as safe as before when we were checking the wrong units. These are GPU MC addresses, so if they fall outside of the VRAM or GART apertures, they end up at the GPU default page, so this should be safe from a security perspective. v2: Just disable the warning. It just spams the log and there's nothing the user can do about it.

2010-09-13drm/radeon/kms: fix the colorbuffer CS checker for r300-r500Marek Olšák
This commit fixes bogus CS rejection if it contains a sequence of the following operations: - Set the color buffer 0. track->cb[i].robj becomes non-NULL. - Render. - Set a larger zbuffer than the previously-set color buffer. - Set a larger scissor area as well. - Set the color channel mask to 0 to do depth-only rendering. - Render. --> rejected, because track->cb[i].robj remained non-NULL, therefore the conditional checking for the color channel mask and friends is not performed, and the larger scissor area causes the rejection. This fixes bugs: - https://bugs.freedesktop.org/show_bug.cgi?id=29762 - https://bugs.freedesktop.org/show_bug.cgi?id=28869 And maybe some others which seem to look the same.
