2016-07-12drm/qxl: Remove deprecated create_singlethread_workqueueBhaktipriya Shridhar
System workqueues have been able to handle high level of concurrency for a long time now and there's no reason to use dedicated workqueues just to gain concurrency. Since the workqueue in the QXL graphics device driver is involved in freeing and processing the release ring (workitem &qdev->gc_workqxl, maps to gc_work which calls qxl_garbage_collect) and is not being used on a memory reclaim path, dedicated gc_queue has been replaced with the use of system_wq. Unlike a dedicated per-cpu workqueue created with create_workqueue(), system_wq allows multiple work items to overlap executions even on the same CPU; however, a per-cpu workqueue doesn't have any CPU locality or global ordering guarantees unless the target CPU is explicitly specified and thus the increase of local concurrency shouldn't make any difference. flush_work() has been called in qxl_device_fini() to ensure that there are no pending tasks while disconnecting the driver.

2016-07-11drm/vc4: Implement precise vblank timestamping.Mario Kleiner
Precise vblank timestamping is implemented via the usual scanout position based method. On VC4 the pixelvalves PV do not have a scanout position register. Only the hardware video scaler HVS has a similar register which describes which scanline for the output is currently composited and stored in the HVS fifo for later consumption by the PV. This causes a problem in that the HVS runs at a much faster clock (system clock / audio gate) than the PV which runs at video mode dot clock, so the unless the fifo between HVS and PV is full, the HVS will progress faster in its observable read line position than video scan rate, so the HVS position reading can't be directly translated into a scanout position for timestamp correction. Additionally when the PV is in vblank, it doesn't consume from the fifo, so the fifo gets full very quickly and then the HVS stops compositing until the PV enters active scanout and starts consuming scanlines from the fifo again, making new space for the HVS to composite. Therefore a simple translation of HVS read position into elapsed time since (or to) start of active scanout does not work, but for the most interesting cases we can still get useful and sufficiently accurate results: 1. The PV enters active scanout of a new frame with the fifo of the HVS completely full, and the HVS can refill any fifo line which gets consumed and thereby freed up by the PV during active scanout very quickly. Therefore the PV and HVS work effectively in lock-step during active scanout with the fifo never having more than 1 scanline freed up by the PV before it gets refilled. The PV's real scanout position is therefore trailing the HVS compositing position as scanoutpos = hvspos - fifosize and we can get the true scanoutpos as HVS readpos minus fifo size, so precise timestamping works while in active scanout, except for the last few scanlines of the frame, when the HVS reaches end of frame, stops compositing and the PV catches up and drains the fifo. This special case would only introduce minor errors though. 2. If we are in vblank, then we can only guess something reasonable. If called from vblank irq, we assume the irq is usually dispatched with minimum delay, so we can take a timestamp taken at entry into the vblank irq handler as a baseline and then add a full vblank duration until the guessed start of active scanout. As irq dispatch is usually pretty low latency this works with relatively low jitter and good results. If we aren't called from vblank then we could be anywhere within the vblank interval, so we return a neutral result, simply the current system timestamp, and hope for the best. Measurement shows the generated timestamps to be rather precise, and at least never off more than 1 vblank duration worst-case. Limitations: Doesn't work well yet for interlaced video modes, therefore disabled in interlaced mode for now. v2: Use the DISPBASE registers to determine the FIFO size (changes by anholt) Signed-off-by: Mario Kleiner <mario.kleiner.de@gmail.com> Signed-off-by: Eric Anholt <eric@anholt.net> Reviewed-and-tested-by: Mario Kleiner <mario.kleiner.de@gmail.com> (v2)

2016-07-08drm/i915: Fill unused GGTT with scratch pages for VT-dChris Wilson
One of the numerous VT-d workarounds we require is that the display hardware reads past the end of the buffer triggering VT-d faults. This is acknowledged in the code as being safe "since we fill the unused portions of the GGTT with the scratch page". Alas, that is no longer always true and so we trigger DMAR read faults. Skylake also requires another workaround to avoid mixing VT-d and unpopulated PTE, and so there we also need to ensure we fill unused entries with the scratch page.
