2015-01-28sna: Clear the per-crtc shadow buffer if they are clippedChris Wilson
Before we present a buffer on the CRTC, we try to make sure it is initialised with the current contents. However, if it is larger than the screen then not all the buffer may be initialised and so we need to clear it first. Signed-off-by: Chris Wilson <chris@chris-wilson.co.uk>
2015-01-27sna/dri2: Check for comparable back/front pitches more carefullyChris Wilson
Suppose for a moment that we don't have a DRI2Buffer associated with the Drawable just yet... This could happen after a Composite redirect as the front buffer may created (and so associated with the new Pixmap) after the back buffer is recreated.

2015-01-23sna: GETPROPBLOB only works with exact length matchesChris Wilson
If the blob is smaller than the space we offer for the read, it skips the read. So make sure we repeat the read in this case as well. Signed-off-by: Chris Wilson <chris@chris-wilson.co.uk>
2015-01-23sna: Add a fallback DBG for the git versionChris Wilson
In case the version numbering is disabled, like on Arch, include it anyway in the full debug log. Signed-off-by: Chris Wilson <chris@chris-wilson.co.uk>
2015-01-22sna/dri2: Only preserve back buffers with the same pitchChris Wilson
We can only pageflip if we don't change the pitch, otherwise we simulate the pageflip with modeset. The idea is that once we have exchanged the buffers, we will quickly settle down to a steady state scenario where each buffer has the same pitch. We can encourage this further by only keeping those buffers around that do have the same pitch as the current front. Signed-off-by: Chris Wilson <chris@chris-wilson.co.uk>

2015-01-19Set the vdpau driver to va_glAdel Gadllah
This at least works when the wrapper is installed, there is no i9xx vdpau driver. This should for example improve flash which only supports vdpau. The expectation is that most software will use vaapi in preference for -intel, for example kodi which supports both vdpau and vaapi video acceleration methods. [A quick discussion with Peter Frühberger clarified that kodi should indeed continue to work fine and will not be confused if we expose an actual vdpau driver.]

2015-01-17sna/gen6+: Prefer not to switch away from active RENDER pipelineChris Wilson
If we don't have a good reason to switch to BLT, don't jump engines simply because the BLT is idle if our target bo is active on the RENDER pipeline. Signed-off-by: Chris Wilson <chris@chris-wilson.co.uk>
2015-01-16sna/dri2: Exchange flags when exchanging DRI2Buffers after SwapBuffersChris Wilson
Along with the name, pitch, bo, we should also preserve the flags. Signed-off-by: Chris Wilson <chris@chris-wilson.co.uk>
2015-01-16sna/dri2: Track tracking of active-scanout for back buffer replacementChris Wilson
In the end it turned out to a small typo, s/scanout/active_scanout/ in consideration of reusing the cache. Though there are a number of very useful debug improvements along the way. Signed-off-by: Chris Wilson <chris@chris-wilson.co.uk>
2015-01-15sna/gen6+: Prefer using RENDER pipeline for uncached destinations on large GTChris Wilson
If the sampler can be cached, the RENDER pipeline can write to an uncached destination surface faster than main memory bw would seem to actually allow... Notably, performance does not drastically fall off with small areas compared to BLT as it once did. However, using a solid source (which is not yet implemented well in the RENDER pipeline) is still much faster with the BLT. Signed-off-by: Chris Wilson <chris@chris-wilson.co.uk>

2015-01-14sna: Actually check for has_wc_mmap before useChris Wilson
The callers assumed that the callee was doing the check and vice versa. The result was that no did and we ended up using an incoherent mapping instead on old kernels. Bugzilla: https://bugs.freedesktop.org/show_bug.cgi?id=88350 Signed-off-by: Chris Wilson <chris@chris-wilson.co.uk>
2015-01-13sna: Wrap direct access to ScrnInfoPtr->pScreenChris Wilson

2015-01-13sna: Only instantiate the frontbuffer on the GPU if usedChris Wilson
If we are a PRIME slave, we never need to allocate any memory for the frontbuffer, so skip the forced allocation during modesets. Signed-off-by: Chris Wilson <chris@chris-wilson.co.uk>
2015-01-13sna: Combine slave CRTC offsets with rotationChris Wilson
When applying both a slave offset and an output rotation, order is important. To get the order right, we need to combine the two into a single transformation. Reported-by: Maarten Lankhorst <maarten.lankhorst@canonical.com> Signed-off-by: Chris Wilson <chris@chris-wilson.co.uk>

2015-01-13sna: Throw away CRTC damage if the CRTC is outside the screen boundsChris Wilson
As the damage is entirely empty due to the screen clipping, we can save a few electrons by not recording it. Ordinarily, we will then get the damage event later when the screen is resized. Signed-off-by: Chris Wilson <chris@chris-wilson.co.uk>

2015-01-09sna: Actually set the priv->mapped type for mmap(wc)Chris Wilson

2015-01-09sna: Wrap mmap accessors with sigtrap to catch oom SIGBUSChris Wilson
Accessing a mmap'ed pointer (especially our shmemfs backed bo) can throw SIGBUS when out of memory, for which we use sigtrap for graceful failure. Signed-off-by: Chris Wilson <chris@chris-wilson.co.uk>
2015-01-09sna: Replace assert with conditional setting of sna_pixmap->mappedChris Wilson
The status of sna_pixmap->mapped was changed with the introduction of mmap(wc), but the code was still asserting that the mmap could only be cached. References: https://bugs.freedesktop.org/show_bug.cgi?id=88112#c20 Signed-off-by: Chris Wilson <chris@chris-wilson.co.uk>
2015-01-09sna: Add a couple of guards against using the GPU to write into snooped boChris Wilson
Since gen2 cannot rendering into a snooped bo, we have to be careful before trusting the CPU bo as a GPU target. Signed-off-by: Chris Wilson <chris@chris-wilson.co.uk>

2015-01-08sna: Differentiate between disabling CRTC and turning off DPMSChris Wilson
xf86DisableUnusedFunctions() uses crtc->dpms(off) to disable unused pipes. In this case, we do want to explicitly disable the CRTC to release any shared state (e.g. PLLs and encoders). However, the user can also request for the DPMS to be disabled, either via the DPMS extension or the ScreenSaver. Here, we don't want to full disable the pipe as that incurs extra latency (and risk of failure) when switching the display back on. In order to distinguish the two cases, we can hook into the user paths and skip disabling the CRTCs.

2015-01-06sna: Copy mode.vrefresh between kernel and XChris Wilson
The value is typically used only for human readable output, though some kernel modules do use it for preferred mode matching (notably not i915.ko today).
