drm/panfrost: Add support for devcoredump In the event of a job timeout, debug dump information will be written into /sys/class/devcoredump. Inspired by etnaviv's similar feature.

drm/panfrost: Require the simple_ondemand governor Panfrost depends on the simple_ondemand governor, and therefore it's a required configuration. Select it.

drm/panfrost: Select devfreq Currently, there is some logic for the driver to work without devfreq. However, the driver actually fails to probe if !CONFIG_PM_DEVFREQ. Fix this by selecting devfreq, and drop the additional checks for devfreq.

drm/panfrost: depend on !GENERIC_ATOMIC64 when using COMPILE_TEST Since panfrost has a 'select' on IOMMU_IO_PGTABLE_LPAE we must depend on the same set of flags. Otherwise IOMMU_IO_PGTABLE_LPAE will be forced on even though it cannot build (no support for cmpxchg64). This fixes the following warning from kconfig: WARNING: unmet direct dependencies detected for IOMMU_IO_PGTABLE_LPAE Depends on [n]: IOMMU_SUPPORT [=y] && (ARM || ARM64 || COMPILE_TEST [=y] && !GENERIC_ATOMIC64 [=y]) Selected by [y]: - DRM_PANFROST [=y] && HAS_IOMEM [=y] && DRM [=y] && (ARM || ARM64 || COMPILE_TEST [=y]) && MMU [=y] Reported-by: kbuild test robot <lkp@intel.com> Signed-off-by: Steven Price <steven.price@arm.com> Signed-off-by: Rob Herring <robh@kernel.org> Link: https://patchwork.freedesktop.org/patch/msgid/20190417152928.10790-1-steven.price@arm.com

drm/panfrost: Add initial panfrost driver This adds the initial driver for panfrost which supports Arm Mali Midgard and Bifrost family of GPUs. Currently, only the T860 and T760 Midgard GPUs have been tested. v2: - Add GPU reset on job hangs (Tomeu) - Add RuntimePM and devfreq support (Tomeu) - Fix T760 support (Tomeu) - Add a TODO file (Rob, Tomeu) - Support multiple in fences (Tomeu) - Drop support for shared fences (Tomeu) - Fill in MMU de-init (Rob) - Move register definitions back to single header (Rob) - Clean-up hardcoded job submit todos (Rob) - Implement feature setup based on features/issues (Rob) - Add remaining Midgard DT compatible strings (Rob) v3: - Add support for reset lines (Neil) - Add a MAINTAINERS entry (Rob) - Call dma_set_mask_and_coherent (Rob) - Do MMU invalidate on map and unmap. Restructure to do a single operation per map/unmap call. (Rob) - Add a missing explicit padding to struct drm_panfrost_create_bo (Rob) - Fix 0-day error: "panfrost_devfreq.c:151:9-16: ERROR: PTR_ERR applied after initialization to constant on line 150" - Drop HW_FEATURE_AARCH64_MMU conditional (Rob) - s/DRM_PANFROST_PARAM_GPU_ID/DRM_PANFROST_PARAM_GPU_PROD_ID/ (Rob) - Check drm_gem_shmem_prime_import_sg_table() error code (Rob) - Re-order power on sequence (Rob) - Move panfrost_acquire_object_fences() before scheduling job (Rob) - Add NULL checks on array pointers in job clean-up (Rob) - Rework devfreq (Tomeu) - Fix devfreq init with no regulator (Rob) - Various WS and comments clean-up (Rob) Cc: Maarten Lankhorst <maarten.lankhorst@linux.intel.com> Cc: Maxime Ripard <maxime.ripard@bootlin.com> Cc: Sean Paul <sean@poorly.run> Cc: David Airlie <airlied@linux.ie> Cc: Daniel Vetter <daniel@ffwll.ch> Cc: Lyude Paul <lyude@redhat.com> Reviewed-by: Alyssa Rosenzweig <alyssa@rosenzweig.io> Reviewed-by: Eric Anholt <eric@anholt.net> Reviewed-by: Steven Price <steven.price@arm.com> Signed-off-by: Marty E.
