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

2026-07-06T20:56:33+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/umsch: tidy up the ucode name string handling

Make the constant parts of the name part of the string we pass to amdgpu_ucode_request(). Only the version number varies from IP to IP. Reviewed-by: Saleemkhan Jamadar Signed-off-by: Alex Deucher Cc: Lang Yu

drm/amdgpu/umsch: fix ucode check

2025-02-17T19:08:53+00:00

Return an error if the IP version doesn't match otherwise we end up passing a NULL string to amdgpu_ucode_request. We should never hit this in practice today since we only enable the umsch code on the supported IP versions, but add a check to be safe.

drm/amd: Add the capability to mark certain firmware as "required"

2024-12-10T15:26:51+00:00

Some of the firmware that is loaded by amdgpu is not actually required. For example the ISP firmware on some SoCs is optional, and if it's not present the ISP IP block just won't be initialized. The firmware loader core however will show a warning when this happens like this: ``` Direct firmware load for amdgpu/isp_4_1_0.bin failed with error -2 ``` To avoid confusion for non-required firmware, adjust the amd-ucode helper to take an extra argument indicating if the firmware is required or optional. On optional firmware use firmware_request_nowarn() instead of request_firmware() to avoid the warnings.
