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
