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 --- Documentation/gpu/amdgpu.rst | 24 ++++++++++++++++++++++++ 1 file changed, 24 insertions(+) (limited to 'Documentation/gpu') diff --git a/Documentation/gpu/amdgpu.rst b/Documentation/gpu/amdgpu.rst index 0efede580039..d9ea09ec8e24 100644 --- a/Documentation/gpu/amdgpu.rst +++ b/Documentation/gpu/amdgpu.rst @@ -202,3 +202,27 @@ busy_percent .. kernel-doc:: drivers/gpu/drm/amd/amdgpu/amdgpu_pm.c :doc: busy_percent + +GPU Product Information +======================= + +Information about the GPU can be obtained on certain cards +via sysfs + +product_name +------------ + +.. kernel-doc:: drivers/gpu/drm/amd/amdgpu/amdgpu_device.c + :doc: product_name + +product_number +-------------- + +.. kernel-doc:: drivers/gpu/drm/amd/amdgpu/amdgpu_device.c + :doc: product_name + +serial_number +------------- + +.. kernel-doc:: drivers/gpu/drm/amd/amdgpu/amdgpu_device.c + :doc: serial_number -- cgit v1.2.3
