Hello, This is the 5th version of the kernel driver for Mali CSF-based GPUs, and, unless someone has good reasons to block the merging of this driver, I expect it to be the last one (the gallium driver is now in a decent state, and is mostly waiting for the kernel driver to be accepted). A branch based on drm-misc-next is available here[1], and here is another one [2] containing extra patches to have things working on rk3588. The CSF firmware binary is now merged in linux-firmware [3]. The mesa MR adding v10 support on top of panthor is available here [4]. Here is a non-exhaustive changelog, check each commit for a detailed changelog. v5: - No fundamental changes in this v5 - Various bug fixes (see the per-commit changelogs) - Various docs/typos fixes v4: - Fix various bugs in the VM logic - Address comments from Steven, Liviu, Ketil and Chris - Move tiler OOM handling out of the scheduler interrupt handling path so we can properly recover when the system runs out of memory, and panthor is blocked trying to allocate heap chunks - Rework the heap locking to support concurrent chunk allocation. Not sure if this is supposed to happen, but we need to be robust against userspace passing the same heap context to two scheduling groups. Wasn't needed before the tiler_oom rework, because heap allocation base serialized by the scheduler lock. - Make kernel BO destruction robust to NULL/ERR pointers 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 [1]https://gitlab.freedesktop.org/panfrost/linux/-/tree/panthor-v5 [2]https://gitlab.freedesktop.org/panfrost/linux/-/tree/panthor-v5+rk3588 [3]https://git.kernel.org/pub/scm/linux/kernel/git/firmware/linux-firmware.git/tree/arm/mali/arch10.8 [4]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 | 549 +++ drivers/gpu/drm/panthor/panthor_device.h | 393 ++ drivers/gpu/drm/panthor/panthor_drv.c | 1473 +++++++ drivers/gpu/drm/panthor/panthor_fw.c | 1362 +++++++ drivers/gpu/drm/panthor/panthor_fw.h | 504 +++ drivers/gpu/drm/panthor/panthor_gem.c | 228 ++ drivers/gpu/drm/panthor/panthor_gem.h | 144 + drivers/gpu/drm/panthor/panthor_gpu.c | 482 +++ drivers/gpu/drm/panthor/panthor_gpu.h | 52 + drivers/gpu/drm/panthor/panthor_heap.c | 597 +++ drivers/gpu/drm/panthor/panthor_heap.h | 39 + drivers/gpu/drm/panthor/panthor_mmu.c | 2766 +++++++++++++ drivers/gpu/drm/panthor/panthor_mmu.h | 102 + drivers/gpu/drm/panthor/panthor_regs.h | 239 ++ drivers/gpu/drm/panthor/panthor_sched.c | 3501 +++++++++++++++++ drivers/gpu/drm/panthor/panthor_sched.h | 48 + include/uapi/drm/panthor_drm.h | 945 +++++ 26 files changed, 13936 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
