This patch modifies the user queue management to use preempt/restore operations instead of full map/unmap for queue eviction scenarios where applicable. The changes include: 1. Introduces new helper functions: - amdgpu_userqueue_preempt_helper() - amdgpu_userqueue_restore_helper() 2. Updates queue state management to track PREEMPTED state 3. Modifies eviction handling to use preempt instead of unmap: - amdgpu_userq_evict_all() now uses preempt_helper - amdgpu_userq_restore_all() now uses restore_helper The preempt/restore approach provides better performance during queue eviction by avoiding the overhead of full queue teardown and setup. Full map/unmap operations are still used for initial setup/teardown and system suspend scenarios. v2: rename amdgpu_userqueue_restore_helper/amdgpu_userqueue_preempt_helper to amdgpu_userq_restore_helper/amdgpu_userq_preempt_helper for consistency. (Alex) v3: amdgpu_userq_stop_sched_for_enforce_isolation() and amdgpu_userq_start_sched_for_enforce_isolation() should use preempt and restore (Alex) Reviewed-by: Alex Deucher <alexander.deucher@amd.com> Signed-off-by: Alex Deucher <alexander.deucher@amd.com> Signed-off-by: Jesse Zhang <Jesse.Zhang@amd.com> Signed-off-by: Alex Deucher <alexander.deucher@amd.com> |

Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the reStructuredText markup notation.
Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
