From 67416bf85345b6990fe2adc42ab082bfefc578bd Mon Sep 17 00:00:00 2001 From: Kent Russell Date: Mon, 13 Dec 2021 13:59:43 -0500 Subject: [PATCH] drm/amdgpu: Access the FRU on Aldebaran This is supported, although the offset is different from VG20, so fix that with a variable and enable getting the product name and serial number from the FRU. Do this for all SKUs since all SKUs have the FRU Signed-off-by: Kent Russell Reviewed-by: Alex Deucher Signed-off-by: Alex Deucher --- drivers/gpu/drm/amd/amdgpu/amdgpu_fru_eeprom.c | 13 ++++++++++--- 1 file changed, 10 insertions(+), 3 deletions(-) diff --git a/drivers/gpu/drm/amd/amdgpu/amdgpu_fru_eeprom.c b/drivers/gpu/drm/amd/amdgpu/amdgpu_fru_eeprom.c index fdca0a447e749..2a786e7886277 100644 --- a/drivers/gpu/drm/amd/amdgpu/amdgpu_fru_eeprom.c +++ b/drivers/gpu/drm/amd/amdgpu/amdgpu_fru_eeprom.c @@ -56,6 +56,9 @@ static bool is_fru_eeprom_supported(struct amdgpu_device *adev) return true; else return false; + case CHIP_ALDEBARAN: + /* All Aldebaran SKUs have the FRU */ + return true; default: return false; } @@ -91,10 +94,14 @@ int amdgpu_fru_get_product_info(struct amdgpu_device *adev) unsigned char buff[AMDGPU_PRODUCT_NAME_LEN+2]; u32 addrptr; int size, len; + int offset = 2; if (!is_fru_eeprom_supported(adev)) return 0; + if (adev->asic_type == CHIP_ALDEBARAN) + offset = 0; + /* If algo exists, it means that the i2c_adapter's initialized */ if (!adev->pm.smu_i2c.algo) { DRM_WARN("Cannot access FRU, EEPROM accessor not initialized"); @@ -137,7 +144,7 @@ int amdgpu_fru_get_product_info(struct amdgpu_device *adev) len = AMDGPU_PRODUCT_NAME_LEN - 1; } /* Start at 2 due to buff using fields 0 and 1 for the address */ - memcpy(adev->product_name, &buff[2], len); + memcpy(adev->product_name, &buff[offset], len); adev->product_name[len] = '\0'; addrptr += size + 1; @@ -155,7 +162,7 @@ int amdgpu_fru_get_product_info(struct amdgpu_device *adev) DRM_WARN("FRU Product Number is larger than 16 characters.
