| | * drm/vc4: Bind the HVS before we bind the individual CRTCs.Eric Anholt2016-07-11
| | | | | | | | | | | | | | | | | | | | | | | | | | | We need to be able to look at the CRTC's registers in the HVS as part of initialization, while the HVS doesn't need to look at the PV registers.

| | * | drm/vc4: clean up error exit path on failed dpi_connector allocationColin Ian King2016-06-06
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | There is redundant code in the clean up exit path when dpi_connector fails to be allocated. The current code checks if connector is NULL before destroying it, in fact, connector is NULL at this point so the check is redundant and can be removed. The final clean up is that we can remove the goto fail with a simple return and the unused variable ret.

| | * | drm/vc4: Make pageflip completion handling more robust.Mario Kleiner2016-06-06
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Protect both the setup of the pageflip event and the latching of the new requested displaylist head pointer by the event lock, so we can't get into a situation where vc4_atomic_flush latches the new display list via HVS_WRITE, then immediately gets preempted before queueing the pageflip event, then the page-flip completes in hw and the vc4_crtc_handle_page_flip() runs and no-ops due to lack of a pending pageflip event, then vc4_atomic_flush continues and only then queues the pageflip event - after the page flip handling already no-oped. This would cause flip completion handling only at the next vblank - one frame too late. In vc4_crtc_handle_page_flip() check the actual DL head pointer in SCALER_DISPLACTX against the requested pointer for page flip to make sure that the flip actually really completed in the current vblank and doesn't get deferred to the next one because the DL head pointer was written a bit too late into SCALER_DISPLISTX, after start of vblank, and missed the boat. This avoids handling a pageflip completion too early - one frame too early. According to Eric, DL head pointer updates which were written into the HVS DISPLISTX reg get committed to hardware at the last pixel of active scanout. Our vblank interrupt handler, as triggered by PV_INT_VFP_START irq, gets to run earliest at the first pixel of HBLANK at the end of the last scanline of active scanout, ie. vblank irq handling runs at least 1 pixel duration after a potential pageflip completion happened in hardware. This ordering of events in the hardware, together with the lock protection and SCALER_DISPLACTX sampling of this patch, guarantees that pageflip completion handling only runs at exactly the vblank irq of actual pageflip completion in all cases. Background info from Eric about the relative timing of HVS, PV's and trigger points for interrupts, DL updates: https://lists.freedesktop.org/archives/dri-devel/2016-May/107510.html Tested on RPi 2B with hardware timing measurement equipment and shown to no longer complete flips too early or too late.

At worst this means vblanks will be somewhat funky on a setup that very likely no one still runs. So let's just nuke it. Plan B would be to set it unconditionally in drm_vblank_init for kms drivers, instead of in each driver separately. So if this patch breaks anything please only restore the hunks in drmP.h and drm_irq.c, plus add a check for DRIVER_MODESET in drm_vblank_init. Stumbled over this in a discussion on irc with Chris.

But really mostly trivial stuff: - MAINTAINERS updates from Emil - rename async to nonblock in atomic_commit to avoid the confusion between nonblocking ioctl and async flip (= not vblank synced), from Maarten. Needs to be regened with newer drivers, but probably only after -rc1 to catch them all. - actually lockless gem_object_free, plus acked driver conversion patches. All the trickier prep stuff already is in drm-next. - Noralf's nice work for generic defio support in our fbdev emulation. Keeps the udl hack, and qxl is tested by Gerd. * tag 'topic/drm-misc-2016-05-04' of git://anongit.freedesktop.org/drm-intel: (47 commits) drm: Fixup locking WARN_ON mistake around gem_object_free_unlocked drm/etnaviv: Use lockless gem BO free callback drm/imx: Use lockless gem BO free callback drm/radeon: Use lockless gem BO free callback drm/amdgpu: Use lockless gem BO free callback drm/gem: support BO freeing without dev->struct_mutex MAINTAINERS: Add myself for the new VC4 (RPi GPU) graphics driver.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The hardware provides us with separate threads for binning and rendering, and the existing model waits for them both to complete before submitting the next job. Splitting the binning and rendering submissions reduces idle time and gives us approx 20-30% speedup with some x11perf tests such as -line10 and -tilerect1. Improves openarena performance by 1.01897% +/- 0.247857% (n=16). Thanks to anholt for suggesting this. v2: Rebase on the spurious resets fix (change by anholt).
