drm/imx: fix DP CSC handling - Fix the DP color space conversion matrix setup to avoid bugs where disabling the overlay plane while both primary and overlay plane are routed via the CSC unit would not reconfigure the CSC routing properly, leaving the display in a nonworking state, or the CSC setting from a previously set mode would be left behind, causing wrong colors when reenabling the display in certain configurations.

2019-04-25drm/vmwgfx: Fix dma API layer violationThomas Hellstrom1-28/+5
Remove the check for IOMMU presence since it was considered a layer violation. This means we have no reliable way to destinguish between coherent hardware IOMMU DMA address translations and incoherent SWIOTLB DMA address translations, which we can't handle. So always presume the former. This means that if anybody forces SWIOTLB without also setting the vmw_force_coherent=1 vmwgfx option, driver operation will fail, like it will on most other graphics drivers.

2019-04-24Revert "drm/virtio: drop prime import/export callbacks"Dave Airlie3-0/+20
This patch does more harm than good, as it breaks both Xwayland and gnome-shell with X11. Xwayland requires DRI3 & DRI3 requires PRIME. X11 crash for obscure double-free reason which are hard to debug (starting X11 by hand doesn't trigger the crash). I don't see an apparent problem implementing those stub prime functions, they may return an error at run-time, and it seems to be handled fine by GNOME at least. This reverts commit b318e3ff7ca065d6b107e424c85a63d7a6798a69. [airlied: This broke userspace for virtio-gpus, and regressed things from DRI3 to DRI2.

2019-04-15drm/i915: Restore correct bxt_ddi_phy_calc_lane_lat_optim_mask() calculationVille Syrjälä1-2/+4
We are no longer calling bxt_ddi_phy_calc_lane_lat_optim_mask() when intel{hdmi,dp}_compute_config() succeeds, and instead only call it when those fail. This is fallout from the bool->int .compute_config() conversion which failed to invert the return value check before calling bxt_ddi_phy_calc_lane_lat_optim_mask(). Let's just replace it with an early bailout so that it's harder to miss. This restores the correct latency optim setting calculation (which could fix some real failures), and avoids the MISSING_CASE() from bxt_ddi_phy_calc_lane_lat_optim_mask() after intel{hdmi,dp}_compute_config() has failed.

2019-04-14drm/amd/display: If one stream full updates, full update all planesDavid Francis2-0/+22
[Why] On some compositors, with two monitors attached, VT terminal switch can cause a graphical issue by the following means: There are two streams, one for each monitor. Each stream has one plane current state: M1:S1->P1 M2:S2->P2 The user calls for a terminal switch and a commit is made to change both planes to linear swizzle mode. In atomic check, a new dc_state is constructed with new planes on each stream new state: M1:S1->P3 M2:S2->P4 In commit tail, each stream is committed, one at a time. The first stream (S1) updates properly, triggerring a full update and replacing the state current state: M1:S1->P3 M2:S2->P4 The update for S2 comes in, but dc detects that there is no difference between the stream and plane in the new and current states, and so triggers a fast update. The fast update does not program swizzle, so the second monitor is corrupted [How] Add a flag to dc_plane_state that forces full updates When a stream undergoes a full update, set this flag on all changed planes, then clear it on the current stream Subsequent streams will get full updates as a result Signed-off-by: David Francis <David.Francis@amd.com> Signed-off-by: Nicholas Kazlauskas <nicholas.kazlauskas@amd.com> Reviewed-by: Roman Li <Roman.Li@amd.com> Acked-by: Bhawanpreet Lakha <Bhawanpreet Lakha@amd.com> Acked-by: Nicholas Kazlauskas <Nicholas.Kazlauskas@amd.com> Signed-off-by: Alex Deucher <alexander.deucher@amd.com>

[Why] AUX takes longer to reply when using active DP-DVI dongle on some asics resulting in up to 2000+ us edid read (timeout). [How] 1. Adjust AUX poll to match spec 2. Extend the SW timeout. This does not affect normal operation since we exit the loop as soon as AUX acks.

Commit 7769db588384 ("drm/i915/dp: optimize eDP 1.4+ link config fast and narrow") started to optize the eDP 1.4+ link config, both per spec and as preparation for display stream compression support. Sadly, we again face panels that flat out fail with parameters they claim to support. Revert, and go back to the drawing board. v2: Actually revert to max params instead of just wide-and-slow.
