From 559a285816af5b72284a6ed65eb82a68ee497d60 Mon Sep 17 00:00:00 2001 From: Srinivasan Shanmugam Date: Wed, 4 Sep 2024 12:30:16 +0530 Subject: drm/amdgpu: Replace 'amdgpu_job_submit_direct' with 'drm_sched_entity' in cleaner shader MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit This commit replaces the use of amdgpu_job_submit_direct which submits the job to the ring directly, with drm_sched_entity in the cleaner shader job submission process. The change allows the GPU scheduler to manage the cleaner shader job. - The job is then submitted to the GPU using the drm_sched_entity_push_job function, which allows the GPU scheduler to manage the job. This change improves the reliability of the cleaner shader job submission process by leveraging the capabilities of the GPU scheduler.
