Signed-off-by: Chris Wilson <chris@chris-wilson.co.uk>
2014-06-11sna: Prefer to operate inplace on the GPU rather than stall on the CPUChris Wilson

Signed-off-by: Chris Wilson <chris@chris-wilson.co.uk>
2014-06-09sna/dri2: Allow TearFree flipping to individual CRTCChris Wilson
Baby step. We first take advantage of TearFree to allow us to redirect a single CRTC to the DRI2 frontbuffer and so allow a fullscreen game covering a single monitor to avoid expensive blits when running in a multi-monitor setup. Signed-off-by: Chris Wilson <chris@chris-wilson.co.uk>
2014-06-06sna: Auto-retire upload proxiesChris Wilson
This was disabled in commit 9f4f855ba37966fb91d31e9081d03cf72affb154 Author: Chris Wilson <chris@chris-wilson.co.uk> Date: Mon May 26 07:06:18 2014 +0100 sna: Implicit release of upload buffers considered bad as retiring the buffers during the command setup could free one of the earlier bo used in the command. But discarding the snooped bo could still be advantageous. So restore the automatic discard of upload proxies, but make sure we only do between operations.

2014-06-06sna: Only allow the inplace copy to replace a complete overwritten GPU boChris Wilson
And double check after recreating the new GPU bo that is still mappable. Signed-off-by: Chris Wilson <chris@chris-wilson.co.uk>
2014-06-06sna: Rearrange scanout_flush checking to avoid potential crashChris Wilson
With a shadow, we may never attach a GPU bo to the frontbuffer, so be careful when checking the scanout not to dereference that NULL pointer. Signed-off-by: Chris Wilson <chris@chris-wilson.co.uk>
2014-06-05sna: Curry parameters to sna_damage_all()Chris Wilson
It is far easily to pass the PixmapPtr into the function and have it pluck out the width and height than do so in all callers. Signed-off-by: Chris Wilson <chris@chris-wilson.co.uk>
2014-06-05sna: Mark CPU as all damaged when discarding a busy GPU boChris Wilson
When we discard a GPU bo, we need to make sure that the remaining content is marked as only accessible via the CPU shadow pointer. Regression from commit 65301412ecf2d55ab55a2d7faeaa048d4ee8b1d0 Author: Chris Wilson <chris@chris-wilson.co.uk> Date: Sat May 17 20:59:38 2014 +0100 sna: Discard active GPU buffers before uploading into them Reported-by: Jan Alexander Steffens <jan.steffens@gmail.com> Bugzilla: https://bugs.freedesktop.org/show_bug.cgi?id=79517 Signed-off-by: Chris Wilson <chris@chris-wilson.co.uk>
2014-06-05sna/dri2: Enable immediate buffer exchangesChris Wilson
The primary benefit of this is avoid the extra blit when using a compositor and instead propagate the compositor flip on the frontbuffer to the scanout, or equivalently allows a fullscreen game to flip onto the scanout without intervention by TearFree. Signed-off-by: Chris Wilson <chris@chris-wilson.co.uk>
2014-06-03sna: Replace the bo for tiled uploads if not suitable and being replacedChris Wilson

2014-06-02sna: Fix early return in download using the GPUChris Wilson
In commit 961139f5878572ebea268a0bbf47caf05af9093f Author: Chris Wilson <chris@chris-wilson.co.uk> Date: Fri May 30 09:45:15 2014 +0100 sna: Use manual detiling for downloads the code for deciding when to use the GPU was refactored into a new function that also performed the transfer, but failed to notice the early return. Signed-off-by: Chris Wilson <chris@chris-wilson.co.uk>
2014-06-02sna: Add support for DRI3Chris Wilson
Signed-off-by: Chris Wilson <chris@chris-wilson.co.uk>
2014-05-30sna: Use manual detiling for downloadsChris Wilson
If we can CPU mmap the GPU bo, prefer to do so for migration to the CPU as this saves an extra serialisation step. Signed-off-by: Chris Wilson <chris@chris-wilson.co.uk>
2014-05-26sna: Implicit release of upload buffers considered badChris Wilson
Currently upload buffers are automatically decoupled when the buffer is retired. As retiring can happen during command setup after we have selected which bo to render with, this can free the bo we plan to use. Which is bad. Instead of making the release of upload buffers automatic, we manually check whether the buffer is idle before use as a source to consider scrapping it and replacing it with a real GPU bo. This is likely to keep upload buffers alive for longer (limiting reuse between Pixmaps but making reuse of the buffer within a Pixmap more likely) which is both good and bad. (Good - may improve the content cache, bad - may increase the amount of memory used by upload buffers for arbitrary long periods.)

Signed-off-by: Chris Wilson <chris@chris-wilson.co.uk>
2014-05-18sna: Do not mark an upload as a potential replace if the dst is pinnedChris Wilson
This saves us from trying to optimise for an operation that cannot happen as we cannot replace the destination buffer. Signed-off-by: Chris Wilson <chris@chris-wilson.co.uk>
2014-05-16sna: Handle driver failures more gracefullyChris Wilson
Avoid busy-spinning waiting for the cache to expire after a failure. Try to free up any overdue expiration, then if we still fail, we free the entire cache. Currently, it would spin over the expiration until all items were overdue and then freed. Signed-off-by: Chris Wilson <chris@chris-wilson.co.uk>

2014-04-29sna: Discard TearFree damage on partial migrationChris Wilson

2014-04-24sna: INPLACE has early exits in move-to-cpuChris Wilson
We can update the priv->cpu flag more accurately by accounting for the early exits for the INPLACE accessors. Signed-off-by: Chris Wilson <chris@chris-wilson.co.uk>
2014-04-24sna: Be more selective of reusing bo for inplace uploads on !LLCChris Wilson
On older architectures, we can only do the inplace upload into a GPU bo into a new unused bo (that is still in the GPU domain). Signed-off-by: Chris Wilson <chris@chris-wilson.co.uk>

2014-04-05sna: Avoid discarding damage when applying WHOLE hint to pixmap migrationChris Wilson
Once again, we must be careful when promoting from a region to whole pixmap migration that we do not discard required damage.

2014-03-14sna: Ensure we flush SHM pixmaps if rendering to a GPU shadowChris Wilson
Normally, we try to render into the CPU bo of a SHM pixmap. However, under the right circumstances we may try to do a series of rendering into the GPU bo and then copy it back to the CPU bo. In that case, we need to be sure to mark the pixmap as requiring the flush. Signed-off-by: Chris Wilson <chris@chris-wilson.co.uk>
