2021-06-02drm/amdgpu: Add vbios info ioctl interfaceJiawei Gu1-0/+10
Add AMDGPU_INFO_VBIOS_INFO subquery id for detailed vbios info. Provides a way for the user application to get the VBIOS information without having to parse the binary. It is useful for the user to be able to display in a simple way the VBIOS version in their system if they happen to encounter an issue. V2: Use numeric serial. Parse and expose vbios version string. V3: Remove redundant data in drm_amdgpu_info_vbios struct. V4: 64 bit alignment in drm_amdgpu_info_vbios. v5: squash together all the reverts, etc. (Alex) Signed-off-by: Jiawei Gu <Jiawei.Gu@amd.com> Reviewed-by: Alex Deucher <alexander.deucher@amd.com> Signed-off-by: Alex Deucher <alexander.deucher@amd.com>
2021-03-24drm/amdgpu: drop legacy IO bar supportAlex Deucher1-2/+0
It was leftover from radeon where it was required for some specific old hardware. It hasn't been required for ages and the driver already falls back to MMIO when legacy IO is not available. Legacy IO also seems to be problematic on on some thunderbolt devices. Drop it.

2017-08-29drm/amdgpu: Add debugfs file for VBIOS and versionKent Russell1-0/+1
Add 2 debugfs files, one that contains the VBIOS version, and one that contains the VBIOS itself. These won't change after initialization, so we can add the VBIOS version when we parse the atombios information. This ensures that we can find out the VBIOS version, even when the dmesg buffer fills up, and makes it easier to associate which VBIOS version is for which GPU on mGPU configurations. Set the size to 20 characters in case of some weird VBIOS version that exceeds the expected 17 character format (3-8-3\0). The VBIOS dump also allows for easy debugging v2: Move to debugfs, clarify commit message, add VBIOS dump file Signed-off-by: Kent Russell <kent.russell@amd.com> Reviewed-by: Alex Deucher <alexander.deucher@amd.com> Reviewed-by: Christian König <christian.koenig@amd.com> Signed-off-by: Alex Deucher <alexander.deucher@amd.com>
