From 29b4c589b43d8dc0c0a5342cd2ac5da6ec1116b5 Mon Sep 17 00:00:00 2001 From: Jiawei Gu Date: Wed, 14 Apr 2021 16:44:36 +0800 Subject: drm/amdgpu: Add vbios info ioctl interface 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 --- drivers/gpu/drm/amd/amdgpu/atom.h | 10 ++++++++++ 1 file changed, 10 insertions(+) (limited to 'drivers/gpu/drm/amd/amdgpu/atom.h') diff --git a/drivers/gpu/drm/amd/amdgpu/atom.h b/drivers/gpu/drm/amd/amdgpu/atom.h index d279759cab47..0c1839824520 100644 --- a/drivers/gpu/drm/amd/amdgpu/atom.h +++ b/drivers/gpu/drm/amd/amdgpu/atom.h @@ -112,6 +112,10 @@ struct drm_device; #define ATOM_IO_SYSIO 2 #define ATOM_IO_IIO 0x80 +#define STRLEN_NORMAL 32 +#define STRLEN_LONG 64 +#define STRLEN_VERYLONG 254 + struct card_info { struct drm_device *dev; void (* reg_write)(struct card_info *, uint32_t, uint32_t); /* filled by driver */ @@ -140,6 +144,12 @@ struct atom_context { uint32_t *scratch; int scratch_size_bytes; char vbios_version[20]; + + uint8_t name[STRLEN_LONG]; + uint8_t vbios_pn[STRLEN_LONG]; + uint32_t version; + uint8_t vbios_ver_str[STRLEN_NORMAL]; + uint8_t date[STRLEN_NORMAL]; }; extern int amdgpu_atom_debug; -- cgit
