2024-08-29drm/i915: Fix readout degamma_lut mismatch on ilk/snbVille Syrjälä
On ilk/snb the pipe may be configured to place the LUT before or after the CSC depending on various factors, but as there is only one LUT (no split mode like on IVB+) we only advertise a gamma_lut and no degamma_lut in the uapi to avoid confusing userspace. This can cause a problem during readout if the VBIOS/GOP enabled the LUT in the pre CSC configuration. The current code blindly assigns the results of the readout to the degamma_lut, which will cause a failure during the next atomic_check() as we aren't expecting anything to be in degamma_lut since it's not visible to userspace. Fix the problem by assigning whatever LUT we read out from the hardware into gamma_lut.

2024-08-28drm/xe: Use separate rpm lockdep map for non-d3cold-capable devicesThomas Hellström
For non-d3cold-capable devices we'd like to be able to wake up the device from reclaim. In particular, for Lunar Lake we'd like to be able to blit CCS metadata to system at shrink time; at least from kswapd where it's reasonable OK to wait for rpm resume and a preceding rpm suspend. Therefore use a separate lockdep map for such devices and prime it reclaim-tainted. v2: - Rename lockmap acquire- and release functions. (Rodrigo Vivi). - Reinstate the old xe_pm_runtime_lockdep_prime() function and rename it to xe_rpm_might_enter_cb().

2024-08-28Revert "drm/xe/lnl: Offload system clear page activity to GPU"Nirmoy Das
This optimization relied on having to clear CCS on allocations. If there is no need to clear CCS on allocations then this would mostly help in reducing CPU utilization. Revert this patch at this moment because of: 1 Currently Xe can't do clear on free and using a invalid ttm flag, TTM_TT_FLAG_CLEARED_ON_FREE which could poison global ttm pool on multi-device setup. 2 Also for LNL CPU:WB doesn't require clearing CCS as such BO will not be allowed to bind with compression PTE. Subsequent patch will disable clearing CCS for CPU:WB BOs for LNL. This reverts commit 23683061805be368c8d1c7e7ff52abc470cac275.

2024-08-28drm/i915/dp_mst: Fix MST state after a sink resetImre Deak
In some cases the sink can reset itself after it was configured into MST mode, without the driver noticing the disconnected state. For instance the reset may happen in the middle of a modeset, or the (long) HPD pulse generated may be not long enough for the encoder detect handler to observe the HPD's deasserted state. In this case the sink's DPCD register programmed to enable MST will be reset, while the driver still assumes MST is still enabled. Detect this condition, which will tear down and recreate/re-enable the MST topology. v2: - Add a code comment about adjusting the expected DP_MSTM_CTRL register value for SST + SideBand. (Suraj, Jani) - Print a debug message about detecting the link reset. (Jani) - Verify the DPCD MST state only if it wasn't already determined that the sink is disconnected.

2024-08-27drm/xe: Align all VRAM scanout buffers to 64k physical pages when needed.Maarten Lankhorst
For CCS formats on affected platforms, CCS can be used freely, but display engine requires a multiple of 64k physical pages. No other changes are needed. At the BO creation time we don't know if the BO will be used for CCS or not. If the scanout flag is set, and the BO is a multiple of 64k, we take the safe route and force the physical alignment of 64k pages. If the BO is not a multiple of 64k, or the scanout flag was not set at BO creation, we reject it for usage as CCS in display. The physical pages are likely not aligned correctly, and this will cause corruption when used as FB. The scanout flag and size being a multiple of 64k are used together to enforce 64k physical placement. VM_BIND is completely unaffected, mappings to a VM can still be aligned to 4k, just like for normal buffers.
