Add a new context creation parameter to express a global context priority. The priority ranking in descending order is as follows: * AMDGPU_CTX_PRIORITY_HIGH_HW * AMDGPU_CTX_PRIORITY_HIGH_SW * AMDGPU_CTX_PRIORITY_NORMAL * AMDGPU_CTX_PRIORITY_LOW_SW * AMDGPU_CTX_PRIORITY_LOW_HW The driver will attempt to schedule work to the hardware according to the priorities. No latency or throughput guarantees are provided by this patch. This interface intends to service the EGL_IMG_context_priority extension, and vulkan equivalents. Setting a priority above NORMAL requires CAP_SYS_NICE or DRM_MASTER. v2: Instead of using flags, repurpose __pad v3: Swap enum values of _NORMAL _HIGH for backwards compatibility v4: Validate usermode priority and store it v5: Move priority validation into amdgpu_ctx_ioctl(), headline reword v6: add UAPI note regarding priorities requiring CAP_SYS_ADMIN v7: remove ctx->priority v8: added AMDGPU_CTX_PRIORITY_LOW, s/CAP_SYS_ADMIN/CAP_SYS_NICE v9: change the priority parameter to __s32 v10: split priorities into _SW and _HW v11: Allow DRM_MASTER without CAP_SYS_NICE Reviewed-by: Emil Velikov <emil.l.velikov@gmail.com> Reviewed-by: Christian König <christian.koenig@amd.com> Signed-off-by: Andres Rodriguez <andresx7@gmail.com> Signed-off-by: Alex Deucher <alexander.deucher@amd.com> |

Linux kernel ============ This file was moved to Documentation/admin-guide/README.rst Please notice that there are several guides for kernel developers and users. These guides can be rendered in a number of formats, like HTML and PDF. In order to build the documentation, use ``make htmldocs`` or ``make pdfdocs``. There are various text files in the Documentation/ subdirectory, several of them using the Restructured Text markup notation. See Documentation/00-INDEX for a list of what is contained in each file. 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.
