2018-01-08drm/tegra: dc: Properly cleanup overlay planesThierry Reding1-7/+11
The first overlay plane can leak if initialization of the second overlay plane fails. Fix this by properly destroying the first overlay plane on error. Suggested-by: Dmitry Osipenko <digetx@gmail.com> Signed-off-by: Thierry Reding <treding@nvidia.com>
2018-01-08drm/tegra: dc: Fix possible_crtcs mask for planesThierry Reding1-5/+12
Cursor and overlay planes use a possible_crtcs mask based on the DC pipe number. However, DRM requires each bit in the mask to correspond to the index of the CRTC, which will be different from the DC pipe number for a configuration where the first display controller is disabled, or where a deferred probe leads to the first display controller being probed after the first.

2018-01-08drm/tegra: dc: Restore YUV overlay supportThierry Reding1-0/+5
Commit ebae8d07435a ("drm/tegra: dc: Implement legacy blending") broke support for YUV overlays by accident. The reason is that YUV formats are considered opaque because they have no alpha component, but on the other hand no corresponding format with an alpha component can be returned. In the case of YUV formats, the opaque format is the same as the alpha format, so add the special case to restore YUV overlay support.

2018-01-08drm/i915: Don't adjust priority on an already signaled fenceChris Wilson2-1/+4
When we retire a signaled fence, we free the dependency tree. However, we skip clearing the list so that if we then try to adjust the priority of the signaled fence, we may walk the list of freed dependencies.

2018-01-05drm/i915: Whitelist SLICE_COMMON_ECO_CHICKEN1 on Geminilake.Kenneth Graunke2-0/+7
Geminilake requires the 3D driver to select whether barriers are intended for compute shaders, or tessellation control shaders, by whacking a "Barrier Mode" bit in SLICE_COMMON_ECO_CHICKEN1 when switching pipelines. Failure to do this properly can result in GPU hangs. Unfortunately, this means it needs to switch mid-batch, so only userspace can properly set it. To facilitate this, the kernel needs to whitelist the register. The workarounds page currently tags this as applying to Broxton only, but that doesn't make sense. The documentation for the register it references says the bit userspace is supposed to toggle only exists on Geminilake. Empirically, the Mesa patch to toggle this bit appears to fix intermittent GPU hangs in tessellation control shader barrier tests on Geminilake; we haven't seen those hangs on Broxton. v2: Mention WA #0862 in the comment (it doesn't have a name).

This series builds upon the set of fixes previously submitted to move Armada DRM closer to atomic modeset. We're nowhere near yet, but this series helps to get us closer by unifying some of the differences between the primary and overlay planes. New features added allows userspace to disable the primary plane if overlay is full screen and there's nothing obscuring the colorkey - this saves having to fetch an entire buffer containing nothing but colorkey when displaying full screen video.

2018-01-04drm/i915: Pass DMA_ATTR_NO_WARN to dma_map_sg()Chris Wilson1-3/+4
In some iommu, e.g. swiotlb, the available space can be quite limited. So we employ a trial-and-error approach to seeing if our large contiguous chunks can fit, and if that fails we try again with smaller chunks after trying to free our own lazily allocated blobs. As we use a trial-and-error approach, we do not want dma_map_sg() to emit a WARN of its own accord, we want to gracefully report the error back to the caller instead. Note that our noisy culprit, swiotlb, doesn't honour the flag, yet.

Display WA #1183 was recently added to workaround "Failures when enabling DPLL0 with eDP link rate 2.16 or 4.32 GHz and CD clock frequency 308.57 or 617.14 MHz (CDCLK_CTL CD Frequency Select 10b or 11b) used in this enabling or in previous enabling." This workaround was designed to minimize the impact only to save the bad case with that link rates. But HW engineers indicated that it should be safe to apply broadly, although they were expecting the DPLL0 link rate to be unchanged on runtime. We need to cover 2 cases: when we are in fact enabling DPLL0 and when we are just changing the frequency with small differences.

2018-01-03drm/i915/execlists: Clear context-switch interrupt earlier in the resetChris Wilson1-12/+21
Move the clearing of the CS-interrupt into the engine reset phase, before the current init-hw phase. This helps clarify that we clear the pending interrupts prior to any restarting of the execlists.

2018-01-02drm/etnaviv: couple runtime PM management to submit object lifetimeLucas Stach3-27/+7
As long as there is an active submit, we want the GPU to stay awake. This is slightly complicated by the fact that we really want to wake the GPU at the last possible moment to achieve maximum power savings. Signed-off-by: Lucas Stach <l.stach@pengutronix.de>
2018-01-02drm/etnaviv: move GPU active handling to bo pin/unpinLucas Stach2-10/+4
The active count is used to check if the BO is idle, where idle is defined as not active on the GPU and all VM mappings and reference counts dropped to the initial state. As the idling of the mappings and references now only happens in the submit cleanup, the active state handling must be moved to the same location in order to keep the userspace semantics.
