[PATCH v4 00/10] drm: rcar-du: Rework CRTC and groups for atomic commits
by Kieran Bingham 14 Jan '21

14 Jan '21

This patch series refactors atomic commit tail handling in the R-Car DU driver to simplify the code flow, and open the door to further optimisations. It rebases the series posted by Laurent "[PATCH v3 00/10] drm: rcar-du: Rework CRTC and groups for atomic commits", which was itself based upon work that I had started originally. A few minor updates were required for the rebase, and review comments from v3 were handled, along with minor updates based upon suggestions from 'checkpatch.pl --strict'. The R-Car DU is a bit of a strange beast, with support for up to four CRTCs that share resources in groups of two CRTCs. Depending on the generation, planes can be shared (on Gen 1 and Gen 2), and output routing configuration is also handled at the group level to some extent. Furthermore, many configuration parameters, especially those related to routing or clock handling, require the whole group to be restarted to take effect, even when the parameter itself affects a single CRTC only. This hardware architecture is difficult to handle properly on the software side, and has resulted in group usage being reference-counted while CRTC usage only tracks the enabled state. Calls are then unbalanced and difficult to trace, especially for the configuration of output routing, and implementation of new shared resources is hindered. This patch series aims at solving this problem. The series starts with 4 patches that touch the API between the DU and VSP drivers. It became apparent that we need to split the configuration of the VSP to allow fine grain control of setting the mode configuration and enabling/disabling of the pipeline. To support the cross-component API, the new interface is added in patch 01/10, including an implementation of vsp1_du_setup_lif() to support the transition. Patch 02/10 prepares for the new call flow that will call the atomic flush handler before enabling the pipeline. The DRM usage is adapted in patch 03/10, before the call is removed entirely in patch 04/10. The next two patches convert CRTC clock handling and initial setup, potentially called from both the CRTC .atomic_begin() and .atomic_enable() operations, to a simpler code flow controlled by the commit tail handler. Patch 05/10 takes the CRTCs out of standby and put them back in standby respectively at the beginning and end of the commit tail handler, based on the CRTC atomic state instead of state information stored in the custom rcar_du_crtc structure. Patch 06/10 then performs a similar change for the CRTC mode setting configuration. Finally, the last four patches introduce a DRM private object for the CRTC groups, along with an associated state. Patch 07/10 adds a helper macro to easily iterate over CRTC groups, and patch 08/10 adds the group private objects and empty states. Patches 09/10 and 10/10 respectively move the group setup and routing configuration under control of the commit tail handler, simplifying the configuration and moving state information from driver structures to state structures. More refactoring is expected, with plane assignment being moved to group states, and group restart being optimised to avoid flickering. Better configuration of pixel clocks could also be implemented on top of this series. The whole series has been tested on Salvator-XS with the DU test suite (http://git.ideasonboard.com/renesas/kms-tests.git). No failure or change in behaviour has been noticed.

Hi Dave & Daniel, Here is the first PR for v5.12. There are quite a few patches accumulated after the holidays as usual: Most importantly there are fixes to the clear residual security mitigations to avoid GPU hangs caused by them. Further there is option to allow the user to decide to disable such mitigations similar to CPU side (i915.mitigations=auto,!residuals), if they are an expert user and wish to do so. Of course, usual caveats apply to disabling any security mitigations! For Tigerlake, a fix to reduce the likelihood of DMAR errors when IOMMU is enabled (MTBF bump from 10 secs to hours) and correction to detecting the device stepping. Addition of W/As for DG1 and TGL. Tuning the RPS algorithm further to limit to RPe on parking an engine. Plenty of refactoring, cleanups and optimizing code in preparation of upcoming series. The usual amount of selftest and documentation fixes. Then there are 3 other fixes for user reported/visible bugs; GPU hang due to wrong MOCS caching for index used by HW, false error message for case where GuC firmware doesn't load on first instance of the retry-loop and supplementing the GuC firmware table for Cometlake SKUs. Fixes for pre-emption on Gen8-era devices. Build and runtime fixes for 32-bit machines. Regards, Joonas PS. After you merge this, I will proceed to backmerge drm-next so that we can have a common topic branches for din and dign as requested by Jani and Rodrigo. *** drm-intel-gt-next-2021-01-14: UAPI Changes: - Deprecate I915_PMU_LAST and optimize state tracking (Tvrtko) Avoid relying on last item ABI marker in i915_drm.h, add a comment to mark as deprecated.

Hi all, After merging the drm-misc tree, today's linux-next build (arm multi_v7_defconfig) failed like this: drivers/gpu/drm/drm_cache.c: In function 'drm_need_swiotlb': drivers/gpu/drm/drm_cache.c:202:6: error: implicit declaration of function 'mem_encrypt_active' [-Werror=implicit-function-declaration] 202 | if (mem_encrypt_active()) | ^~~~~~~~~~~~~~~~~~ Caused by commit 3abc66706385 ("drm: Implement drm_need_swiotlb() in drm_cache.c") I have used the drm-misc tree from next-20210107 again for today. -- Cheers, Stephen Rothwell
