drm/tegra: Preparatory work for v5.19 This contains a single patch from a series that's ready to go for v5.10 but is also a shared build-time dependency for an IOMMU series that is planned for v5.20. The idea is to take this into v5.19 to fulfill that dependency and remove the need for close coordination for the two series. Signed-off-by:

In commit a670ff57 ("drm/msm/dpu: always use mdp device to scale bandwidth") we fully moved interconnect stuff to the DPU driver. This had no change for sc7180 but _did_ have an impact for other SoCs. It made them match the sc7180 scheme. Unfortunately, the sc7180 scheme seems like it was a bit broken. Specifically the interconnect needs to be on for more than just the DPU driver's AXI bus. In the very least it also needs to be on for the DSI driver's AXI bus. This can be seen fairly easily by doing this on a ChromeOS sc7180-trogdor class device: set_power_policy --ac_screen_dim_delay=5 --ac_screen_off_delay=10 sleep 10 cd /sys/bus/platform/devices/ae94000.dsi/power echo on > control When you do that, you'll get a warning splat in the logs about "gcc_disp_hf_axi_clk status stuck at 'off'". One could argue that perhaps what I have done above is "illegal" and that it can't happen naturally in the system because in normal system usage the DPU is pretty much always on when DSI is on. That being said: * In official ChromeOS builds (admittedly a 5.4 kernel with backports) we have seen that splat at bootup. * Even though we don't use "autosuspend" for these components, we don't use the "put_sync" variants. Thus plausibly the DSI could stay "runtime enabled" past when the DPU is enabled. Techncially we shouldn't do that if the DPU's suspend ends up yanking our clock. Let's change things such that the "bare minimum" request for the interconnect happens in the mdss driver again. That means that all of the children can assume that the interconnect is on at the minimum bandwidth. We'll then let the DPU request the higher amount that it wants. It should be noted that this isn't as hacky of a solution as it might initially appear. Specifically: * Since MDSS and DPU individually get their own references to the interconnect then the framework will actually handle aggregating them. The two drivers are _not_ clobbering each other. * When the Qualcomm interconnect driver aggregates it takes the max of all the peaks. Thus having MDSS request a peak, as we're doing here, won't actually change the total interconnect bandwidth (it won't be added to the request for the DPU). This perhaps explains why the "average" requested in MDSS was historically 0 since that one _would_ be added in. NOTE also that in the downstream ChromeOS 5.4 and 5.15 kernels, we're also seeing some RPMH hangs that are addressed by this fix. These hangs are showing up in the field and on _some_ devices with enough stress testing of suspend/resume. Specifically right at suspend time with a stack crawl that looks like this (from chromeos-5.15 tree): rpmh_write_batch+0x19c/0x240 qcom_icc_bcm_voter_commit+0x210/0x420 qcom_icc_set+0x28/0x38 apply_constraints+0x70/0xa4 icc_set_bw+0x150/0x24c dpu_runtime_resume+0x50/0x1c4 pm_generic_runtime_resume+0x30/0x44 __genpd_runtime_resume+0x68/0x7c genpd_runtime_resume+0x12c/0x20c __rpm_callback+0x98/0x138 rpm_callback+0x30/0x88 rpm_resume+0x370/0x4a0 __pm_runtime_resume+0x80/0xb0 dpu_kms_enable_commit+0x24/0x30 msm_atomic_commit_tail+0x12c/0x630 commit_tail+0xac/0x150 drm_atomic_helper_commit+0x114/0x11c drm_atomic_commit+0x68/0x78 drm_atomic_helper_disable_all+0x158/0x1c8 drm_atomic_helper_suspend+0xc0/0x1c0 drm_mode_config_helper_suspend+0x2c/0x60 msm_pm_prepare+0x2c/0x40 pm_generic_prepare+0x30/0x44 genpd_prepare+0x80/0xd0 device_prepare+0x78/0x17c dpm_prepare+0xb0/0x384 dpm_suspend_start+0x34/0xc0 We don't completely understand all the mechanisms in play, but the hang seemed to come and go with random factors. It's not terribly surprising that the hang is gone after this patch since the line of code that was failing is no longer present in the kernel.

dp_catalog_ctrl_reset() will software reset DP controller. But it will not reset programmable registers to default value. DP driver still have to clear mask bits to interrupt status registers to disable interrupts after software reset of controller. At current implementation, dp_ctrl_reset_irq_ctrl() will software reset dp controller but did not call dp_catalog_ctrl_enable_irq(false) to clear hpd related interrupt mask bits to disable hpd related interrupts due to it mistakenly think hpd related interrupt mask bits will be cleared by software reset of dp controller automatically. This mistake may cause system to crash during suspending procedure due to unexpected irq fired and trigger event thread to access dp controller registers with controller clocks are disabled. This patch fixes system crash during suspending problem by removing "enable" flag condition checking at dp_ctrl_reset_irq_ctrl() so that hpd related interrupt mask bits are cleared to prevent unexpected from happening.

Convert fdinfo format to one documented in drm-usage-stats.rst. It turned out that the existing implementation was actually completely nonsense. The calculated percentages indeed represented the usage of the engine, but with varying time slices. So 10% usage for application A could mean something completely different than 10% usage for application B. Completely nuke that and just use the now standardized nanosecond interface. v2: drop the documentation change for now, nuke percentage calculation v3: only account for each hw_ip, move the time_spend to the ctx mgr. v4: move general ctx changes into separate patch, rework the fdinfo to ctx_mgr interface so that all usages are calculated at once, drop some unecessary and dangerous refcount dance. v5: add one more comment how we calculate the time spend Signed-off-by:Tvrtko Ursulin <tvrtko.ursulin@intel.com> Signed-off-by:

According to the KMS man page, there is a "Coverage" alpha blend mode that assumes the pixel color values have NOT been pre-multiplied and will be done when the actual blending to the background color values happens. Previously, this mode hasn't been enabled in our driver and it was assumed that all normal overlay planes are pre-multiplied by default. When a 3rd party app is used to input a image in a specific format, e.g. PNG, as a source of a overlay plane to blend with the background primary plane, the pixel color values are not pre-multiplied. So by adding "Coverage" blend mode, our driver will support those cases.
