drm/panfrost: Require the simple_ondemand governorPanfrost depends on the simple_ondemand governor, and thereforeit's a required configuration.

drm/panfrost: Select devfreqCurrently, 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 checksfor devfreq.Signed-off-by: Ezequiel Garcia Signed-off-by: Rob Herring Link: https://patchwork.freedesktop.org/patch/msgid/20190517150042.776-1-ezequiel@collabora.com List of files: /linux-6.15/drivers/gpu/drm/panfrost/Kconfig

db594ba3 - drm/panfrost: depend on !GENERIC_ATOMIC64 when using COMPILE_TEST

Wed, 17 Apr 2019 15:29:28 +0000

drm/panfrost: depend on !GENERIC_ATOMIC64 when using COMPILE_TESTSince panfrost has a 'select' on IOMMU_IO_PGTABLE_LPAE we must depend onthe same set of flags. Otherwise IOMMU_IO_PGTABLE_LPAE will be forced oneven 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 Signed-off-by: Steven Price Signed-off-by: Rob Herring Link: https://patchwork.freedesktop.org/patch/msgid/20190417152928.10790-1-steven.price@arm.com List of files: /linux-6.15/drivers/gpu/drm/panfrost/Kconfig

f3ba9122 - drm/panfrost: Add initial panfrost driver

Mon, 10 Sep 2018 19:27:58 +0000

drm/panfrost: Add initial panfrost driverThis adds the initial driver for panfrost which supports Arm MaliMidgard and Bifrost family of GPUs. Currently, only the T860 andT760 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 Cc: Maxime Ripard Cc: Sean Paul Cc: David Airlie Cc: Daniel Vetter Cc: Lyude Paul Reviewed-by: Alyssa Rosenzweig Reviewed-by: Eric Anholt Reviewed-by: Steven Price Signed-off-by: Marty E.
