accel/rocket: Add IOCTL for BO creation This uses the SHMEM DRM helpers and we map right away to the CPU and NPU sides, as all buffers are expected to be accessed from both. v2: - Sync the IOMMUs for the other cores when mapping and unmapping. v3: - Make use of GPL-2.0-only for the copyright notice (Jeff Hugo) v6: - Use mutexes guard (Markus Elfring) v7: - Assign its own IOMMU domain to each client, for isolation (Daniel Stone and Robin Murphy) v8: - Correctly acquire a reference to the IOMMU (Robin Murphy) - Allocate DMA address ourselves with drm_mm (Robin Murphy) - Use refcount_read (Heiko Stuebner) - Remove superfluous dma_sync_sgtable_for_device (Robin Murphy) Reviewed-by: Jeffrey Hugo <quic_jhugo@quicinc.com> Tested-by: Heiko Stuebner <heiko@sntech.de> Signed-off-by: Tomeu Vizoso <tomeu@tomeuvizoso.net> Signed-off-by: Jeff Hugo <jeff.hugo@oss.qualcomm.com> Link: https://lore.kernel.org/r/20250721-6-10-rocket-v9-3-77ebd484941e@tomeuvizoso.net

accel/rocket: Add job submission IOCTL Using the DRM GPU scheduler infrastructure, with a scheduler for each core. Userspace can decide for a series of tasks to be executed sequentially in the same core, so SRAM locality can be taken advantage of. The job submission code was initially based on Panfrost. v2: - Remove hardcoded number of cores - Misc. style fixes (Jeffrey Hugo) - Repack IOCTL struct (Jeffrey Hugo) v3: - Adapt to a split of the register block in the DT bindings (Nicolas Frattaroli) - Make use of GPL-2.0-only for the copyright notice (Jeff Hugo) - Use drm_* logging functions (Thomas Zimmermann) - Rename reg i/o macros (Thomas Zimmermann) - Add padding to ioctls and check for zero (Jeff Hugo) - Improve error handling (Nicolas Frattaroli) v6: - Use mutexes guard (Markus Elfring) - Use u64_to_user_ptr (Jeff Hugo) - Drop rocket_fence (Rob Herring) v7: - Assign its own IOMMU domain to each client, for isolation (Daniel Stone and Robin Murphy) v8: - Use reset lines to reset the cores (Robin Murphy) - Use the macros to compute the values for the bitfields (Robin Murphy) - More descriptive name for the IRQ (Robin Murphy) - Simplify job interrupt handing (Robin Murphy) - Correctly acquire a reference to the IOMMU (Robin Murphy) - Specify the size of the embedded structs in the IOCTLs for future extensibility (Rob Herring) - Expose only 32 bits for the address of the regcmd BO (Robin Murphy) Tested-by: Heiko Stuebner <heiko@sntech.de> Reviewed-by: Jeff Hugo <jeff.hugo@oss.qualcomm.com> Signed-off-by: Tomeu Vizoso <tomeu@tomeuvizoso.net> Signed-off-by: Jeff Hugo <jeff.hugo@oss.qualcomm.com> Link: https://lore.kernel.org/r/20250721-6-10-rocket-v9-4-77ebd484941e@tomeuvizoso.net

accel/rocket: Add IOCTLs for synchronizing memory accesses The NPU cores have their own access to the memory bus, and this isn't cache coherent with the CPUs. Add IOCTLs so userspace can mark when the caches need to be flushed, and also when a writer job needs to be waited for before the buffer can be accessed from the CPU. Initially based on the same IOCTLs from the Etnaviv driver. v2: - Don't break UABI by reordering the IOCTL IDs (Jeff Hugo) v3: - Check that padding fields in IOCTLs are zero (Jeff Hugo) v6: - Fix conversion logic to make sure we use DMA_BIDIRECTIONAL when needed (Lucas Stach) v8: - Always sync BOs in both directions (Robin Murphy) Reviewed-by: Jeff Hugo <jeff.hugo@oss.qualcomm.com> Tested-by: Heiko Stuebner <heiko@sntech.de> Signed-off-by: Tomeu Vizoso <tomeu@tomeuvizoso.net> Signed-off-by: Jeff Hugo <jeff.hugo@oss.qualcomm.com> Link: https://lore.kernel.org/r/20250721-6-10-rocket-v9-5-77ebd484941e@tomeuvizoso.net

accel/rocket: Add IOCTLs for synchronizing memory accesses The NPU cores have their own access to the memory bus, and this isn't cache coherent with the CPUs. Add IOCTLs so userspace can mark when the caches need to be flushed, and also when a writer job needs to be waited for before the buffer can be accessed from the CPU. Initially based on the same IOCTLs from the Etnaviv driver. v2: - Don't break UABI by reordering the IOCTL IDs (Jeff Hugo) v3: - Check that padding fields in IOCTLs are zero (Jeff Hugo) v6: - Fix conversion logic to make sure we use DMA_BIDIRECTIONAL when needed (Lucas Stach) v8: - Always sync BOs in both directions (Robin Murphy) Reviewed-by: Jeff Hugo <jeff.hugo@oss.qualcomm.com> Tested-by: Heiko Stuebner <heiko@sntech.de> Signed-off-by: Tomeu Vizoso <tomeu@tomeuvizoso.net> Signed-off-by: Jeff Hugo <jeff.hugo@oss.qualcomm.com> Link: https://lore.kernel.org/r/20250721-6-10-rocket-v9-5-77ebd484941e@tomeuvizoso.net
