drm/amdgpu: move struct amdgpu_wb and helpers into separate files

2026-07-08T18:20:30+00:00

Move struct amdgpu_wb and helpers out of the monolithic header amdgpu.h into its own dedicated header amdgpu_wb.h. Add amdgpu_wb_init() and amdgpu_wb_fini() into amdgpu_wb.h. Move functions amdgpu_device_wb_get(), amdgpu_device_wb_free(), amdgpu_device_wb_init(), and amdgpu_device_wb_fini() out of amdgpu_device.c into new dedicated amdgpu_wb.c file. Removed static from functions amdgpu_device_wb_init() and amdgpu_device_wb_fini(). Rename functions amdgpu_device_wb_get(), amdgpu_device_wb_free(), amdgpu_device_wb_init(), and amdgpu_device_wb_fini() into amdgpu_wb_get(), amdgpu_wb_free(), amdgpu_wb_init(), and amdgpu_wb_fini(). Update amdgpu/Makefile to build amdgpu_wb.o. This is part of the ongoing effort to reduce the size of amdgpu.h into their own respective separate headers.

drm/amdgpu: only use working sdma schedulers for ttm

2026-04-17T19:41:12+00:00

It's possible that some sdma instances aren't working so we shouldn't try to use them from TTM. To achieve this, delay the call to amdgpu_sdma_set_buffer_funcs_scheds after the rings have been tested, and then use the 'ready' property to decide if a sched should be used or not. Note that currently it's not doing much, because if the ring helper fails for any ring, the whole sdma block init fails. --- v5: check buffer_funcs_enabled from amdgpu_ttm_access_memory_sdma --- Signed-off-by: Pierre-Eric Pelloux-Prayer Reviewed-by: Christian König Signed-off-by: Alex Deucher

drm/amdgpu: pass all the sdma scheds to amdgpu_mman

2026-04-17T19:41:12+00:00

This will allow the use of all of them for clear/fill buffer operations. Since drm_sched_entity_init requires a scheduler array, we store schedulers rather than rings. For the few places that need access to a ring, we can get it from the sched using container_of. Since the code is the same for all sdma versions, add a new helper amdgpu_sdma_set_buffer_funcs_scheds to set buffer_funcs_scheds based on the number of sdma instances. Note: the new sched array is identical to the amdgpu_vm_manager one. These 2 could be merged.

drm/amdgpu: wire up defines, shifts and masks through SI code

2025-04-07T19:18:32+00:00

To be able to remove as much duplicated defines, the different files containing definitions, shifts and masks must be properly included. Once done, the code will be migrated where needed to shifts and masks and proper defines, before removing useless defines in the end. Signed-off-by: Alexandre Demers Signed-off-by: Alex Deucher
