Hello, This is the 3rd version of the kernel driver for Mali CSF-based GPUs. With all the DRM dependencies being merged (drm-sched single entity and drm_gpuvm), I thought now was a good time to post a new version. Note that the iommu series we depend on [1] has been merged recently. The only remaining dependency that hasn't been merged yet is this rather trival drm_gpuvm [2] patch. As for v2, I pushed a branch based on drm-misc-next and containing all the dependencies that are not yet available in drm-misc-next here[3], and another [4] containing extra patches to have things working on rk3588. The CSF firmware binary can be found here[5], and should be placed under /lib/firmware/arm/mali/arch10.8/mali_csffw.bin. The mesa MR adding v10 support on top of panthor is available here [6]. Regarding the GPL2+MIT relicensing, Liviu did an audit and found two more people that I didn't spot initially: Clément Péron for the devfreq code, and Alexey Sheplyakov for some bits in panthor_gpu.c. Both are Cc-ed on the relevant patches. The rest of the code is either new, or covered by the Linaro, Arm and Collabora acks. And here is a non-exhaustive changelog, check each commit for a detailed changelog. v3; - Quite a few changes at the MMU/sched level to make the fix some race conditions and deadlocks - Addition of the a sync-only VM_BIND operation (to support vkQueueSparseBind with zero commands). - Addition of a VM_GET_STATE ioctl - Various cosmetic changes (see the commit changelogs for more details) - Various fixes (see the commit changelogs for more details) v2: - Rename the driver (pancsf -> panthor) - Split the commit adding the driver to ease review - Use drm_sched for dependency tracking/job submission - Add a VM_BIND ioctl - Add the concept of exclusive VM for BOs that are only ever mapped to a single VM - Document the code and uAPI - Add a DT binding doc Regards, Boris [1]https://lore.kernel.org/linux-arm-kernel/20231124142434.1577550-1-boris.brezillon@xxxxxxxxxxxxx/T/ [2]https://patchwork.freedesktop.org/patch/570380/ [3]https://gitlab.freedesktop.org/panfrost/linux/-/tree/panthor-v3 [4]https://gitlab.freedesktop.org/panfrost/linux/-/tree/panthor-v3+rk3588 [5]https://gitlab.com/firefly-linux/external/libmali/-/raw/firefly/firmware/g610/mali_csffw.bin [6]https://gitlab.freedesktop.org/mesa/mesa/-/merge_requests/26358 Boris Brezillon (13): drm/panthor: Add uAPI drm/panthor: Add GPU register definitions drm/panthor: Add the device logical block drm/panthor: Add the GPU logical block drm/panthor: Add GEM logical block drm/panthor: Add the devfreq logical block drm/panthor: Add the MMU/VM logical block drm/panthor: Add the FW logical block drm/panthor: Add the heap logical block drm/panthor: Add the scheduler logical block drm/panthor: Add the driver frontend block drm/panthor: Allow driver compilation drm/panthor: Add an entry to MAINTAINERS Liviu Dudau (1): dt-bindings: gpu: mali-valhall-csf: Add support for Arm Mali CSF GPUs .../bindings/gpu/arm,mali-valhall-csf.yaml | 147 + Documentation/gpu/driver-uapi.rst | 5 + MAINTAINERS | 11 + drivers/gpu/drm/Kconfig | 2 + drivers/gpu/drm/Makefile | 1 + drivers/gpu/drm/panthor/Kconfig | 23 + drivers/gpu/drm/panthor/Makefile | 15 + drivers/gpu/drm/panthor/panthor_devfreq.c | 283 ++ drivers/gpu/drm/panthor/panthor_devfreq.h | 25 + drivers/gpu/drm/panthor/panthor_device.c | 497 +++ drivers/gpu/drm/panthor/panthor_device.h | 381 ++ drivers/gpu/drm/panthor/panthor_drv.c | 1454 +++++++ drivers/gpu/drm/panthor/panthor_fw.c | 1332 +++++++ drivers/gpu/drm/panthor/panthor_fw.h | 504 +++ drivers/gpu/drm/panthor/panthor_gem.c | 227 ++ drivers/gpu/drm/panthor/panthor_gem.h | 144 + drivers/gpu/drm/panthor/panthor_gpu.c | 481 +++ drivers/gpu/drm/panthor/panthor_gpu.h | 52 + drivers/gpu/drm/panthor/panthor_heap.c | 517 +++ drivers/gpu/drm/panthor/panthor_heap.h | 36 + drivers/gpu/drm/panthor/panthor_mmu.c | 2653 +++++++++++++ drivers/gpu/drm/panthor/panthor_mmu.h | 101 + drivers/gpu/drm/panthor/panthor_regs.h | 237 ++ drivers/gpu/drm/panthor/panthor_sched.c | 3410 +++++++++++++++++ drivers/gpu/drm/panthor/panthor_sched.h | 48 + include/uapi/drm/panthor_drm.h | 892 +++++ 26 files changed, 13478 insertions(+) create mode 100644 Documentation/devicetree/bindings/gpu/arm,mali-valhall-csf.yaml create mode 100644 drivers/gpu/drm/panthor/Kconfig create mode 100644 drivers/gpu/drm/panthor/Makefile create mode 100644 drivers/gpu/drm/panthor/panthor_devfreq.c create mode 100644 drivers/gpu/drm/panthor/panthor_devfreq.h create mode 100644 drivers/gpu/drm/panthor/panthor_device.c create mode 100644 drivers/gpu/drm/panthor/panthor_device.h create mode 100644 drivers/gpu/drm/panthor/panthor_drv.c create mode 100644 drivers/gpu/drm/panthor/panthor_fw.c create mode 100644 drivers/gpu/drm/panthor/panthor_fw.h create mode 100644 drivers/gpu/drm/panthor/panthor_gem.c create mode 100644 drivers/gpu/drm/panthor/panthor_gem.h create mode 100644 drivers/gpu/drm/panthor/panthor_gpu.c create mode 100644 drivers/gpu/drm/panthor/panthor_gpu.h create mode 100644 drivers/gpu/drm/panthor/panthor_heap.c create mode 100644 drivers/gpu/drm/panthor/panthor_heap.h create mode 100644 drivers/gpu/drm/panthor/panthor_mmu.c create mode 100644 drivers/gpu/drm/panthor/panthor_mmu.h create mode 100644 drivers/gpu/drm/panthor/panthor_regs.h create mode 100644 drivers/gpu/drm/panthor/panthor_sched.c create mode 100644 drivers/gpu/drm/panthor/panthor_sched.h create mode 100644 include/uapi/drm/panthor_drm.h -- 2.43.0
