* drm/radeon/kms: MC vram map needs to be >= pci aperture sizeAlex Deucher2010-10-261-0/+3
| | | | | | | | | | | | | | 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. This can lead to hangs. Signed-off-by: Alex Deucher <alexdeucher@gmail.com> Cc: stable@kernel.org Signed-off-by: Dave Airlie <airlied@redhat.com>

* drm/radeon/r600: fix tiling issues in CS checker.Dave Airlie2010-10-262-10/+22
| | | | | | | | | | | | | | 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.

Fixable by switching inputs on the receiver a couple of times. With this patch, my receiver has not lost sync yet (> 40 tries). Fourth version, now based on drm-intel-next from: git://git.kernel.org/pub/scm/linux/kernel/git/ickle/drm-intel.git Two questions still remain: I'm assuming that the sdvo hardware also stores a header ECC byte in the MSB of the first dword - is this correct?

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | If the userspace driver is using a constant relocation array with a static buffer, they will pass the same relocation array back to the kernel. So we *do* need to update the presumed offset value in those relocations to reflect the current object so that they remain correct with future batchbuffers and we avoid the necessity of having to suspend execution and perform redundant relocations. Fixes the regression introduced by 12f889c for applications using absolute addressing on trees of buffer (i.e. the current consumers of libdrm_intel.so).

| | | | | | | | | | | | | | | | | | | | | | To handle retirements, we need per-ring tracking of active objects. To handle evictions, we need global tracking of active objects.

| | | | | | | | | | | | | | | | | | | | | | | | | | The most frequent relocation within a batchbuffer is a contiguous sequence of vertex buffer relocations, for which we can virtually eliminate the drm_gem_object_lookup() overhead by caching the last handle to object translation. In doing so we refactor the pin and relocate retry loop out of do_execbuffer into its own helper function and so improve the error paths. Signed-off-by: Chris Wilson <chris@chris-wilson.co.uk>
| * drm/i915: Do interrupible mutex lock first to avoid locking for unreferenceChris Wilson2010-10-191-113/+93
| | | | | | | | | | | | | | | | | | | | | | One of the primarily consumers of the i915 driver is X, a large signal driven application. Frequently when writing into the buffers, there is a pending signal which causes us not to take the interruptible lock but then we need to take that same lock around the object unreference. By rearranging the code to do the interruptible lock as the first check, we can avoid the frequent additional locking around the unreference. Signed-off-by: Chris Wilson <chris@chris-wilson.co.uk>
