From bd607166af7fe31f8d8e9c575f4561a4b56b9f24 Mon Sep 17 00:00:00 2001 From: Kent Russell Date: Fri, 13 Mar 2020 09:21:55 -0400 Subject: drm/amdgpu: Enable reading FRU chip via I2C v3 Allow for reading of information like manufacturer, product number and serial number from the FRU chip. Report the serial number as the new sysfs file serial_number. Note that this only works on server cards, as consumer cards do not feature the FRU chip, which contains this information. v2: Add documentation to amdgpu.rst, add helper functions, rename functions for consistency, fix bad starting offset v3: Remove testing definitions Signed-off-by: Kent Russell Reviewed-by: Andrey Grodzovsky Signed-off-by: Alex Deucher --- drivers/gpu/drm/amd/amdgpu/amdgpu.h | 5 +++++ 1 file changed, 5 insertions(+) (limited to 'drivers/gpu/drm/amd/amdgpu/amdgpu.h') diff --git a/drivers/gpu/drm/amd/amdgpu/amdgpu.h b/drivers/gpu/drm/amd/amdgpu/amdgpu.h index 2992a49ad4a5..b0597a84e137 100644 --- a/drivers/gpu/drm/amd/amdgpu/amdgpu.h +++ b/drivers/gpu/drm/amd/amdgpu/amdgpu.h @@ -974,6 +974,11 @@ struct amdgpu_device { bool pm_sysfs_en; bool ucode_sysfs_en; + + /* Chip product information */ + char product_number[16]; + char product_name[32]; + char serial[16]; }; static inline struct amdgpu_device *amdgpu_ttm_adev(struct ttm_bo_device *bdev) -- cgit v1.2.3
