charset=UTF-8 Content-Transfer-Encoding: 8bit Add amdgpu_queue_mgr, a mechanism that allows disjointing usermode's ring ids from the kernel's ring ids. The queue manager maintains a per-file descriptor map of user ring ids to amdgpu_ring pointers. Once a map is created it is permanent (this is required to maintain FIFO execution guarantees for a context's ring). Different queue map policies can be configured for each HW IP. Currently all HW IPs use the identity mapper, i.e. kernel ring id is equal to the user ring id. The purpose of this mechanism is to distribute the load across multiple queues more effectively for HW IPs that support multiple rings. Userspace clients are unable to check whether a specific resource is in use by a different client. Therefore, it is up to the kernel driver to make the optimal choice. v2: remove amdgpu_queue_mapper_funcs v3: made amdgpu_queue_mgr per context instead of per-fd v4: add context_put on error paths v5: rebase and include new IPs UVD_ENC & VCN_* v6: drop unused amdgpu_ring_is_valid_index (Alex) Reviewed-by: Christian König Signed-off-by: Andres Rodriguez Signed-off-by: Alex Deucher --- drivers/gpu/drm/amd/amdgpu/Makefile | 3 +- drivers/gpu/drm/amd/amdgpu/amdgpu.h | 27 ++- drivers/gpu/drm/amd/amdgpu/amdgpu_cs.c | 128 +++---------- drivers/gpu/drm/amd/amdgpu/amdgpu_ctx.c | 6 + drivers/gpu/drm/amd/amdgpu/amdgpu_queue_mgr.c | 251 ++++++++++++++++++++++++++ 5 files changed, 309 insertions(+), 106 deletions(-) create mode 100644 drivers/gpu/drm/amd/amdgpu/amdgpu_queue_mgr.c (limited to 'drivers/gpu/drm/amd/amdgpu/amdgpu_cs.c') diff --git a/drivers/gpu/drm/amd/amdgpu/Makefile b/drivers/gpu/drm/amd/amdgpu/Makefile index 0344e256f1f6..b62d9e9cfe6c 100644 --- a/drivers/gpu/drm/amd/amdgpu/Makefile +++ b/drivers/gpu/drm/amd/amdgpu/Makefile @@ -24,7 +24,8 @@ amdgpu-y += amdgpu_device.o amdgpu_kms.o \ atombios_encoders.o amdgpu_sa.o atombios_i2c.o \ amdgpu_prime.o amdgpu_vm.o amdgpu_ib.o amdgpu_pll.o \ amdgpu_ucode.o amdgpu_bo_list.o amdgpu_ctx.o amdgpu_sync.o \ - amdgpu_gtt_mgr.o amdgpu_vram_mgr.o amdgpu_virt.o amdgpu_atomfirmware.o + amdgpu_gtt_mgr.o amdgpu_vram_mgr.o amdgpu_virt.o amdgpu_atomfirmware.o \ + amdgpu_queue_mgr.o # add asic specific block amdgpu-$(CONFIG_DRM_AMDGPU_CIK)+= cik.o cik_ih.o kv_smc.o kv_dpm.o \ diff --git a/drivers/gpu/drm/amd/amdgpu/amdgpu.h b/drivers/gpu/drm/amd/amdgpu/amdgpu.h index 1135f19c9e9c..aad1d7bf695a 100644 --- a/drivers/gpu/drm/amd/amdgpu/amdgpu.h +++ b/drivers/gpu/drm/amd/amdgpu/amdgpu.h @@ -776,6 +776,29 @@ int amdgpu_job_submit(struct amdgpu_job *job, struct amdgpu_ring *ring, struct amd_sched_entity *entity, void *owner, struct dma_fence **f);
