2010-06-01drm/vmwgfx: Don't use SVGA_REG_ENABLE in modesetting code.Jakob Bornecrantz
We should not use SVGA_REG_ENABLE anywhere but in the fifo setup code, since it controls whether the device is active. Signed-off-by: Jakob Bornecrantz <jakob@vmware.com> Signed-off-by: Thomas Hellstrom <thellstrom@vmware.com> Signed-off-by: Dave Airlie <airlied@redhat.com>

2010-06-01drm/vmwgfx: Reserve first part of VRAM for framebuffer.Thomas Hellstrom
The host may be touching this part of VRAM at modesetting, even if we never use it ourselves, since we blit screen updates from 3D surfaces. Make sure no DMA buffers are placed in this part of VRAM.

2010-06-01drm/vmwgfx: Add kernel throttling support. Bump minor.Thomas Hellstrom
The throttle_us member in the execbuf argument is now honored. If the member is 0, no waiting for lag will occur, which guarantees backwards compatibility with well-behaved clients. Signed-off-by: Thomas Hellstrom <thellstrom@vmware.com> Signed-off-by: Dave Airlie <airlied@redhat.com>

2010-05-28drm/i915: Unmask interrupt for render engine on SandybridgeZhenyu Wang
With splitted engines on Sandybridge, each engine has its own interrupt control as well. This unmasks the interrupt to properly enable pipe control notify event for render engine. Signed-off-by: Zhenyu Wang <zhenyuw@linux.intel.com> Signed-off-by: Eric Anholt <eric@anholt.net>
2010-05-28drm/i915: Fix PIPE_CONTROL command on SandybridgeZhenyu Wang
Sandybridge(Gen6) has new format for PIPE_CONTROL command, the flush and post-op control are in dword 1 now. This changes command length field for difference between Ironlake and Sandybridge. I tried to test this with noop request and issue PIPE_CONTROL command for each sequence and track notify interrupts, which seems work fine. Hopefully we don't need workaround like on Ironlake for Sandybridge. Signed-off-by: Zhenyu Wang <zhenyuw@linux.intel.com> Signed-off-by: Eric Anholt <eric@anholt.net>
2010-05-28drm/i915: Fix up address spaces in slow_kernel_write()Chris Wilson
Since we now get_user_pages() outside of the mutex prior to performing the copy, we kmap() the page inside the copy routine and so need to perform an ordinary memcpy() and not copy_from_user(). Signed-off-by: Chris Wilson <chris@chris-wilson.co.uk> Signed-off-by: Eric Anholt <eric@anholt.net>
2010-05-28drm/i915: Use non-atomic kmap for slow copy pathsChris Wilson
As we do not have a requirement to be atomic and avoid sleeping whilst performing the slow copy for shmem based pread and pwrite, we can use kmap instead, thus simplifying the code. Signed-off-by: Chris Wilson <chris@chris-wilson.co.uk> Signed-off-by: Eric Anholt <eric@anholt.net>
2010-05-28drm/i915: Avoid moving from CPU domain during pwriteChris Wilson
We can avoid an early clflush when pwriting if we use the current CPU write domain rather than moving the object to the GTT domain for the purposes of the pwrite. This has the advantage of not flushing the presumably hot data that we want to upload into the bo, and of ascribing the clflush to the execution when profiling.

2010-05-28drm/i915: Cleanup after failed initialization of ringbuffersChris Wilson

2010-05-28drm/i915: Reject bind_to_gtt() early if object > apertureChris Wilson
If the object is bigger than the entire aperture, reject it early before evicting everything in a vain attempt to find space. v2: Use E2BIG as suggested by Owain G. Ainsworth. Signed-off-by: Chris Wilson <chris@chris-wilson.co.uk> Cc: stable@kernel.org Signed-off-by: Eric Anholt <eric@anholt.net>

2010-05-28drm/i915: Remove spurious warning "Failure to install fence"Chris Wilson
This particular warning is harmless as we emit during the normal pinning process where the batch buffer requires more fences than is available without eviction. Only if we fail to evict enough fences does this become a problem, so include the requested number of fences in the ultimate *error* message. v2: Remember to compile test even trial patches to remove warnings.

2010-05-28drm/i915: Rebind bo if currently bound with incorrect alignment.Chris Wilson
Whilst pinning the buffer, check that that its current alignment matches the requested alignment. If it does not, rebind. This should clear up any final render errors whilst resuming, for reference: Bug 27070 - [i915] Page table errors with empty ringbuffer https://bugs.freedesktop.org/show_bug.cgi?id=27070 Bug 15502 - render error detected, EIR: 0x00000010 https://bugzilla.kernel.org/show_bug.cgi?id=15502 Bug 13844 - i915 error: "render error detected" https://bugzilla.kernel.org/show_bug.cgi?id=13844 Signed-off-by: Chris Wilson <chris@chris-wilson.co.uk> Cc: stable@kernel.org Signed-off-by: Eric Anholt <eric@anholt.net>

2010-05-28drm/i915: Only print "nothing to do" debug message as required.Chris Wilson
If the FBC is already disabled, then we do not even attempt to disable FBC and so there is no point emitting a debug statement at that point, having already emitted one saying why we are disabling FBC.

2010-05-28drm/i915: Avoid nesting of domain changes when setting display planeChris Wilson
Nesting domain changes will cause confusion when trying to interpret the tracepoints describing the sequence of changes for the object, as well as obscuring the order of operations for the reader of the code.

2010-05-28drm/i915: Hold the spinlock whilst resetting unpin_work along error pathChris Wilson

2010-05-28drm/nouveau: fix dual-link displays when plugged into single-link outputsBen Skeggs
When selecting the native mode for a display we weren't taking into account whether or not it was actually supported on that particular output. This patch modifies our native mode selection to run all modes through mode_valid() first. Signed-off-by: Ben Skeggs <bskeggs@redhat.com>
2010-05-28drm/nv50: obey dcb->duallink_possibleBen Skeggs

2010-05-28drm/nouveau: fix POST detection for certain chipsetsBen Skeggs
We totally fail at detecting un-POSTed chipsets prior to G80. This commit changes the pre-G80 POST detection to read the programmed horizontal total from CRTC 0, and assume the card isn't POSTed if it's 0. NVIDIA use some other heuristics more similar to what we do on G80, but I wasted quite a long time trying to figure out the exact specifics of what they do so we can try this for a bit instead.

2010-05-26drm/i915: Kill dangerous pending-flip debuggingChris Wilson
We can, by virtue of a vblank interrupt firing in the middle of setting up the unpin work (i.e. after we set the unpin_work field and before we write to the ringbuffer) enter intel_finish_page_flip() prior to receiving the pending flip notification. Therefore we can expect to hit intel_finish_page_flip() under normal circumstances without a pending flip and even without installing the pending_flip_obj. This is exacerbated by aperture thrashing whilst binding the framebuffer References: Bug 28079 - "glresize" causes kernel panic in intel_finish_page_flip. https://bugs.freedesktop.org/show_bug.cgi?id=28079 Reported-by: Nick Bowler <nbowler@draconx.ca> Signed-off-by: Chris Wilson <chris@chris-wilson.co.uk> Cc: Jesse Barnes <jbarnes@virtuousgeek.org> Cc: stable@kernel.org Reviewed-by: Jesse Barnes <jbarnes@virtuousgeek.org> Signed-off-by: Eric Anholt <eric@anholt.net>

2010-05-26drm/i915: Add support for interlaced display.Krzysztof Halasa
This doesn't change the clock limits (minimums), i.e. it won't make it output 720x576 PAL nor 720x480 NTSC, but it will work with modes like 1080i etc. (including GLX and textured Xvideo, not sure about the overlay).
