2020-09-29drm/amdgpu: Use SKU instead of DID for FRU check v2Kent Russell
The VG20 DIDs 66a0, 66a1 and 66a4 are used for various SKUs that may or may not have the FRU EEPROM on it. Parse the VBIOS to check for server SKU variants (D131 or D134) until a more general solution can be determined. v2: Remove string-based logic, correct the VBIOS string comment Signed-off-by: Kent Russell <kent.russell@amd.com> Reviewed-by: Felix Kuehling <Felix.Kuehling@amd.com> Signed-off-by: Alex Deucher <alexander.deucher@amd.com>

2020-04-22drm/amdgpu: Disable FRU read on ArcturusKent Russell
Update the list with supported Arcturus chips, but disable for now until final list is confirmed. Ideally we can poll atombios for FRU support, instead of maintaining this list of chips, but this will enable serial number reading for supported ASICs for the time-being.

2020-04-09drm/amdgpu: Re-enable FRU check for most models v5Kent Russell
There is at least 1 VG20 DID that does not have an FRU, and trying to read that will cause a hang. For now, explicitly support reading the FRU for Arcturus and for the WKS VG20 DIDs, and skip for everything else. This re-enables serial number reporting for server cards v2: Add ASIC check v3: Don't default to true for pre-VG20 v4: Use DID instead of parsing the VBIOS v5: Sqaush in overflow warning fix Signed-off-by: Kent Russell <kent.russell@amd.com> Reviewed-by: Alex Deucher <alexander.deucher@amd.com> Signed-off-by: Alex Deucher <alexander.deucher@amd.com>
2020-04-01drm/amdgpu: Fix FRU data checkingKent Russell
Ensure that when we memcpy, we don't end up copying more data than the struct supports. For now, this is 16 characters for product number and serial number, and 32 chars for product name Signed-off-by: Kent Russell <kent.russell@amd.com> Reviewed-by: Alex Deucher <alexander.deucher@amd.com> Signed-off-by: Alex Deucher <alexander.deucher@amd.com>

2020-04-01drm/amdgpu: Enable reading FRU chip via I2C v3Kent Russell
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 <kent.russell@amd.com> Reviewed-by: Andrey Grodzovsky <andrey.grodzovsky@amd.com> Signed-off-by: Alex Deucher <alexander.deucher@amd.com>
