2011-03-23drm/i915: skip redundant operations whilst enabling pipes and planesChris Wilson
If the pipe or plane is already enabled, then we do not need to enable it again and can skip the delay. Similarly if it is already disabled when we want to disable it, we can also skip it. This fixes a regression from b24e717988, which caused the LVDS output on one PineView machine to become corrupt after changing orientation several times.

2011-03-21drm/kernel: vblank wait on crtc > 1Ilija Hadzic
Below is a patch against drm-next branch of 2.6.38-rc8+ kernel that adds the capability to wait on vblank events for CRTCs that are greater than 1 and thus cannot be represented with primary/secondary flags in the legacy interface. It was discussed on the dri-devel list in these two threads: http://lists.freedesktop.org/archives/dri-devel/2011-March/009009.html http://lists.freedesktop.org/archives/dri-devel/2011-March/009025.html This patch extends the interface to drm_wait_vblank ioctl so that crtc>1 can be represented. It also adds a new capability to drm_getcap ioctl so that the user space can check whether the new interface to drm_wait_vblank is supported (and fall back to the legacy interface if not) Signed-off-by: Ilija Hadzic <ihadzic@research.bell-labs.com> Reviewed-by: Mario Kleiner <mario.kleiner at tuebingen.mpg.de> Acked-by: Mario Kleiner <mario.kleiner at tuebingen.mpg.de> Reviewed-by: Alex Deucher <alexdeucher@gmail.com> Tested-by: Alex Deucher <alexdeucher@gmail.com> Signed-off-by: Dave Airlie <airlied@redhat.com>

2011-03-14drm/radeon: fix problem with changing active VRAM size. (v2)Dave Airlie
So we used to use lpfn directly to restrict VRAM when we couldn't access the unmappable area, however this was removed in 93225b0d7bc030f4a93165347a65893685822d70 as it also restricted the gtt placements. However it was only later noticed that this broke on some hw. This removes the active_vram_size, and just explicitly sets it when it changes, TTM/drm_mm will always use the real_vram_size, and the active vram size will change the TTM size used for lpfn setting. We should re-work the fpfn/lpfn to per-placement at some point I suspect, but that is too late for this kernel.

2011-03-08drm/nv50-nvc0: prevent multiple vm/bar flushes occuring simultanenouslyBen Skeggs
The per-vm mutex doesn't prevent this completely, a flush coming from the BAR VM could potentially happen at the same time as one for the channel VM. Not to mention that if/when we get per-client/channel VM, this will happen far more frequently. Signed-off-by: Ben Skeggs <bskeggs@redhat.com> Signed-off-by: Dave Airlie <airlied@redhat.com>
2011-03-08drm/nouveau: fix regression causing ttm to not be able to evict vramBen Skeggs
TTM assumes an error condition from man->func->get_node() means that something went horribly wrong, and causes it to bail. The driver is supposed to return 0, and leave mm_node == NULL to signal that it couldn't allocate any memory.

2011-03-07drm/i915: Only wait on a pending flip if we intend to write to the bufferChris Wilson

2011-03-07drm/i915/dp: Sanity check eDP existenceChris Wilson
Some hardware claims to have both an LVDS panel and an eDP output. Whilst this may be true in a rare case, more often it is just broken hardware. If we see an eDP device we know that it must be connected and so we can confirm its existence with a simple probe.

2011-03-07drm/i915: Rebind the buffer if its alignment constraints changes with tilingChris Wilson
Early gen3 and gen2 chipset do not have the relaxed per-surface tiling constraints of the later chipsets, so we need to check that the GTT alignment is correct for the new tiling. If it is not, we need to rebind. Reported-by: Daniel Vetter <daniel.vetter@ffwll.ch> Reviewed-by: Daniel Vetter <daniel.vetter@ffwll.ch> Signed-off-by: Chris Wilson <chris@chris-wilson.co.uk>
2011-03-07drm/i915: Disable GPU semaphores by defaultChris Wilson
Andi Kleen narrowed his GPU hangs on his Sugar Bay (SNB desktop) rev 09 down to the use of GPU semaphores, and we already know that they appear broken up to Huron River (mobile) rev 08. (I'm optimistic that disabling GPU semaphores is simply hiding another bug by the latency and side-effects of the additional device interaction it introduces...) However, use of semaphores is a massive performance improvement... Only as long as the system remains stable. Enable at your peril.

2011-03-06drm/i915: Do not overflow the MMADDR write FIFOChris Wilson
Whilst the GT is powered down (rc6), writes to MMADDR are placed in a FIFO by the System Agent. This is a limited resource, only 64 entries, of which 20 are reserved for Display and PCH writes, and so we must take care not to queue up too many writes. To avoid this, there is counter which we can poll to ensure there are sufficient free entries in the fifo. "Issuing a write to a full FIFO is not supported; at worst it could result in corruption or a system hang."

This reverts commit c2e0eb167070a6e9dcb49c84c13c79a30d672431. As it turns out, userspace already depends upon being able to enable tiling on existing bo which it promises to be large enough for its purposes i.e. it will not access beyond the end of the last full-tile row.

2011-03-04drm/core: add ioctl to query device/driver capabilitiesBen Skeggs
We're coming to see a need to have a set of generic capability checks in the core DRM, in addition to the driver-specific ioctls that already exist. This patch defines an ioctl to do as such, but does not yet define any capabilities.
