Handles everything that's not related to the FW, the MMU or the scheduler. This is the block dealing with the GPU property retrieval, the GPU block power on/off logic, and some global operations, like global cache flushing. v6: - Add Maxime's and Heiko's acks v5: - Fix GPU_MODEL() kernel doc - Fix test in panthor_gpu_block_power_off() - Add Steve's R-b v4: - Expose CORE_FEATURES through DEV_QUERY v3: - Add acks for the MIT/GPL2 relicensing - Use macros to extract GPU ID info - Make sure we reset clear pending_reqs bits when wait_event_timeout() times out but the corresponding bit is cleared in GPU_INT_RAWSTAT (can happen if the IRQ is masked or HW takes to long to call the IRQ handler) - GPU_MODEL now takes separate arch and product majors to be more readable. - Drop GPU_IRQ_MCU_STATUS_CHANGED from interrupt mask. - Handle GPU_IRQ_PROTM_FAULT correctly (don't output registers that are not updated for protected interrupts). - Minor code tidy ups Cc: Alexey Sheplyakov <asheplyakov@basealt.ru> # MIT+GPL2 relicensing Co-developed-by: Steven Price <steven.price@arm.com> Signed-off-by: Steven Price <steven.price@arm.com> Signed-off-by: Boris Brezillon <boris.brezillon@collabora.com> Acked-by: Steven Price <steven.price@arm.com> # MIT+GPL2 relicensing,Arm Acked-by: Grant Likely <grant.likely@linaro.org> # MIT+GPL2 relicensing,Linaro Acked-by: Boris Brezillon <boris.brezillon@collabora.com> # MIT+GPL2 relicensing,Collabora Reviewed-by: Steven Price <steven.price@arm.com> Acked-by: Maxime Ripard <mripard@kernel.org> Acked-by: Heiko Stuebner <heiko@sntech.de> Link: https://patchwork.freedesktop.org/patch/msgid/20240229162230.2634044-5-boris.brezillon@collabora.com
