From: Srinivasan Shanmugam <[email protected]> This patch adds a new parameter 'enforce_isolation' to the amdgpu_job structure. This parameter is used to determine whether shader isolation should be enforced for a job. The enforce_isolation parameter is then stored in the amdgpu_job structure and used when flushing the VM.
The enforce_isolation field of the amdgpu_job structure is set directly after the job is allocated This change allows more fine-grained control over shader isolation, making it possible to enforce isolation on a per-job basis rather than globally. This can be useful in scenarios where only certain jobs require isolation.
