2022-07-07drm: rcar-du: Fix Alpha blending issue on Gen3LUU HOAI
As per R-Car-Gen3_Common_OPC_Customer_Notifications_V30.1.pdf, unexpected image output(such as incorrect colors or planes being invisible) can happen on the below conditions, as PnALPHAR register is not initialized by reset. When alpha blending (PpMRm.PpSPIM=0b101) is performed and: •two Planes are enabled on any DUn (n=0,1,2,3) oDSPRn= 0x0000 0031 or 0x0000 0013 •or DU0 and DU1 is used for display at the same time oDSPR0= 0x0000 0001 and DSPR1= 0x0000 0003 oDSPR0= 0x0000 0003 and DSPR1= 0x0000 0001 •or DU2 and DU3(H3 Only) is used for display at the same time oDSPR2= 0x0000 0001 and DSPR3= 0x0000 0003 oDSPR2= 0x0000 0003 and DSPR3= 0x0000 0001 This patch set PnALPHAR register to 0 to avoid this issue.

2022-07-06drm/msm/adreno: Defer enabling runpm until hw_init()Rob Clark
To avoid preventing the display from coming up before the rootfs is mounted, without resorting to packing fw in the initrd, the GPU has this limbo state where the device is probed, but we aren't ready to start sending commands to it. This is particularly problematic for a6xx, since the GMU (which requires fw to be loaded) is the one that is controlling the power/clk/icc votes. So defer enabling runpm until we are ready to call gpu->hw_init(), as that is a point where we know we have all the needed fw and are ready to start sending commands to the coproc's.

Replace iommu_present() with a more appropriate check. On Qualcomm platforms the IOMMU can be specified either for the MDP/DPU device or for its parent MDSS device depending on the actual platform. Check both of them, since that is how both DPU and MDP5 drivers work.

2022-07-06drm/i915/guc: Asynchronous flush of GuC log regionsAlan Previn
Both error-capture and relay-logging mechanism use the GuC log infrastructure. That means the KMD must send a log flush complete notification back to GuC after reading the data out. This call is currently being sent synchronously. However, synchronous H2Gs cause problems when the system is backed up. There is no need for this to be synchronous. The KMD wasn't even looking at the return status from it. So make it asynchronous and then there is no issue about time outs.

2022-07-06drm/msm: Avoid unclocked GMU register access in 6xx gpu_busyDouglas Anderson
From testing on sc7180-trogdor devices, reading the GMU registers needs the GMU clocks to be enabled. Those clocks get turned on in a6xx_gmu_resume(). Confusingly enough, that function is called as a result of the runtime_pm of the GPU "struct device", not the GMU "struct device". Unfortunately the current a6xx_gpu_busy() grabs a reference to the GMU's "struct device". The fact that we were grabbing the wrong reference was easily seen to cause crashes that happen if we change the GPU's pm_runtime usage to not use autosuspend. It's also believed to cause some long tail GPU crashes even with autosuspend. We could look at changing it so that we do pm_runtime_get_if_in_use() on the GPU's "struct device", but then we run into a different problem. pm_runtime_get_if_in_use() will return 0 for the GPU's "struct device" the whole time when we're in the "autosuspend delay". That is, when we drop the last reference to the GPU but we're waiting a period before actually suspending then we'll think the GPU is off. One reason that's bad is that if the GPU didn't actually turn off then the cycle counter doesn't lose state and that throws off all of our calculations. Let's change the code to keep track of the suspend state of devfreq. msm_devfreq_suspend() is always called before we actually suspend the GPU and msm_devfreq_resume() after we resume it. This means we can use the suspended state to know if we're powered or not. NOTE: one might wonder when exactly our status function is called when devfreq is supposed to be disabled. The stack crawl I captured was: msm_devfreq_get_dev_status devfreq_simple_ondemand_func devfreq_update_target qos_notifier_call qos_max_notifier_call blocking_notifier_call_chain pm_qos_update_target freq_qos_apply apply_constraint __dev_pm_qos_update_request dev_pm_qos_update_request msm_devfreq_idle_work Fixes: eadf79286a4b ("drm/msm: Check for powered down HW in the devfreq callbacks") Signed-off-by: Douglas Anderson <dianders@chromium.org> Reviewed-by: Rob Clark <robdclark@gmail.com> Patchwork: https://patchwork.freedesktop.org/patch/489124/ Link: https://lore.kernel.org/r/20220610124639.v4.1.Ie846c5352bc307ee4248d7cab998ab3016b85d06@changeid Signed-off-by: Rob Clark <robdclark@chromium.org>

2022-07-06drm/mediatek: dpi: Add dp_intf supportGuillaume Ranquet
Dpintf is the displayport interface hardware unit. This unit is similar to dpi and can reuse most of the code. This patch adds support for mt8195-dpintf to this dpi driver. Main differences are: - 4 pixels for one iteration for dp_intf while dpi is 1 pixel for one iteration. - Input of dp_intf is two pixels per iteration. - Some register contents differ slightly between the two components.

2022-07-06drm/mediatek: dpi: Add YUV422 output supportBo-Chen Chen
Dp_intf supports YUV422 as output format. In MT8195 Chrome project, YUV422 output format is used for 4K resolution. To support this, it is also needed to support color format transfer. Color format transfer is a new feature for both dpi and dpintf of MT8195. The input format could be RGB888 and output format for dp_intf should be YUV422. Therefore, we add a mtk_dpi_matrix_sel() helper to update the DPI_MATRIX_SET register depending on the color format.
