2012-09-05Revert "sna: Flush the batch before a render operation if the GPU is idle"Chris Wilson
This reverts commit ad57ac07a273bf376b74884de47d8ee1e7129fb8. These checks end up being too frequent and not allowing us to batch sufficient commands to offset the overhead of batch submission. Hmm.

2012-09-05uxa: Flush batch immediately after queuing a WAIT_FOR_EVENTChris Wilson
We still encounter hangs with kernel-3.5 with the culprit being a wait on a disabled pipe. As we thoroughly check before that the pipe is still disabled and flush before a modeset, the only possibility that remains is that DPMS is disabling the pipe before we submit. Close that race by always submitting the batch immediately after a WAIT_FOR_EVENT. Signed-off-by: Chris Wilson <chris@chris-wilson.co.uk>
2012-09-05sna: Initialise the empty boxes field of the region before subtracting itChris Wilson
Fixes regression from commit 38fb77af757318e5fb6f605b37306ce4585b11a5 Author: Chris Wilson <chris@chris-wilson.co.uk> Date: Wed Sep 5 08:23:34 2012 +0100 sna: Don't upload ignored cpu damage Signed-off-by: Chris Wilson <chris@chris-wilson.co.uk>
2012-09-05sna: Drop master after discarding framebuffersChris Wilson
As Imre Deak pointed out in the previous patch, drmModeRmFB only works when we hold the DRM master, therefore to prevent a leak of the framebuffer across server reset we need to defer dropping master until after we release our scanouts and modes. Signed-off-by: Chris Wilson <chris@chris-wilson.co.uk>
2012-09-05uxa: fix leakage of FB when closing the screenImre Deak
Calling drmModeRmFB is only allowed in DRM master mode. Since leaving the VT also drops master mode we need to remove the FB before calling I830LeaveVT. This is only a real leak in case of a server reset, otherwise the server process will exit anyway and the kernel will clean up the FB.

2012-09-02sna: Don't retire when searching for a snoopable buffer without hw supportChris Wilson
If the hw/kernel doesn't support snoopable buffers, then it makes little sense to search for one, and force a retire in the certainty of not finding any. Signed-off-by: Chris Wilson <chris@chris-wilson.co.uk>
2012-09-02sna: Tweak placement rules if we already have a CPU boChris Wilson
If we have a CPU bo, consider if it may be quicker to render to it then create a GPU bo. Signed-off-by: Chris Wilson <chris@chris-wilson.co.uk>
2012-09-01sna/dri: Remove busy-wait spin from vblank chaining of swapbuffersChris Wilson
The issue being that, due to the delay, the chained swap would miss its intended vblank and so cause an unwanted reduction in frame throughput and increase output latency even further. Since both client and server have other rate-limiting processes in place, we can forgo the stall here and still keep the clients in check.

2012-09-01sna: Nullify gpu_bo after free in case final release is deferred in destroyChris Wilson
As we may defer the actual release of the pixmap until after completion of the last shm operation, we need to make sure in that case we mark the GPU bo as released to prevent a use-after-free. Signed-off-by: Chris Wilson <chris@chris-wilson.co.uk>
2012-09-01sna/gen2+: Add the missing assertions in case the drawrect is invalidChris Wilson

2012-09-01sna: Discard cached CPU upload early when clearing with a solid fillChris Wilson

2012-08-29sna: Remove inconsistent assertionChris Wilson
As we now may not prefer to use the GPU even if all-damaged and clear, asserting that if we choose to use the CPU if clear is now bogus. Signed-off-by: Chris Wilson <chris@chris-wilson.co.uk>
2012-08-28sna: Align active upload buffers to the next page for reuseChris Wilson
If we write to the same page as it already active on the GPU then despite the invalidation performed at the beginning of each batch, we do not seem to correctly sample the new data.

Signed-off-by: Chris Wilson <chris@chris-wilson.co.uk>
2012-08-28sna: Propagate the request to flush rather than directly submit the batchChris Wilson
The subtly is that we need to reset the mode correctly after submitting the batch which was not handled by kgem_flush(). If we fail to set the appropriate mode then the next operation will be on a random ring, which can prove fatal with SandyBridge+.

Signed-off-by: Chris Wilson <chris@chris-wilson.co.uk>
2012-08-27sna: Track outstanding requests per-ringChris Wilson
In order to properly track when the GPU is idle, we need to account for the completion order that may differ on architectures like SandyBridge with multiple mostly independent rings.

2012-08-27sna: Ensure that we create a GTT mapping for the inplace upload bufferChris Wilson
As the code will optimistically convert a request for a GTT mapping into a CPU mapping if the object is still in the CPU domain, we need to overrule that in this case where we explicitly want to write directly into the GTT and furthermore keep the buffer around in an upload cache.

2012-08-27sna: Force the stall if using a busy ShmPixmap bo with PutImageChris Wilson
As we will stall in the near future to serialise access with the ShmPixmap, we may as well stall first and do a simple copy using the CPU in this highly unlikely scenario. Signed-off-by: Chris Wilson <chris@chris-wilson.co.uk>
