drm/amdgpu: Fix identifier names to function definition arguments in atom.h

2023-08-15T22:07:42+00:00

Fixes the following: WARNING: function definition argument 'struct card_info *' should also have an identifier name WARNING: function definition argument 'uint32_t' should also have an identifier name WARNING: function definition argument 'void *' should also have an identifier name WARNING: function definition argument 'struct atom_context *' should also have an identifier name WARNING: function definition argument 'int' should also have an identifier name WARNING: function definition argument 'uint32_t *' should also have an identifier name WARNING: Unnecessary space before function pointer name ERROR: space prohibited after that '*' (ctx:BxW) CHECK: Prefer kernel type 'u32' over 'uint32_t' Cc: Guchun Chen Cc: Christian König Cc: Alex Deucher Cc: "Pan, Xinhui" Signed-off-by: Srinivasan Shanmugam Reviewed-by: Guchun Chen Signed-off-by: Alex Deucher

drm/amd: Avoid reading the VBIOS part number twice

2023-07-21T20:52:24+00:00

The VBIOS part number is read both in amdgpu_atom_parse() as well as in atom_get_vbios_pn() and stored twice in the `struct atom_context` structure. Remove the first unnecessary read and move the `pr_info` line from that read into the second. v2: squash in unused variable removal Signed-off-by: Mario Limonciello Reviewed-by: Alex Deucher Signed-off-by: Alex Deucher

drm/amdgpu: Add vbios info ioctl interface

2021-06-02T02:55:39+00:00

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 Reviewed-by: Alex Deucher Signed-off-by: Alex Deucher

drm/amdgpu: drop legacy IO bar support

2021-03-24T03:31:17+00:00

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. Reviewed-by: Christian König Signed-off-by: Alex Deucher Cc: Nicholas Johnson

drm/amdgpu: Add debugfs file for VBIOS and version

2017-08-29T19:27:54+00:00

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 Reviewed-by: Alex Deucher Reviewed-by: Christian König Signed-off-by: Alex Deucher
