This includes overwriting device + identifying fields such as the MAC address, VPD area, and device + serial number.

If no overwrite mask is provided, the firmware will be +instructed to preserve all settings and identifying fields when updating. + Regions ======= diff --git a/drivers/net/ethernet/intel/ice/ice_devlink.c b/drivers/net/ethernet/intel/ice/ice_devlink.c index c3d61c246f0b..e17b44059eae 100644 --- a/drivers/net/ethernet/intel/ice/ice_devlink.c +++ b/drivers/net/ethernet/intel/ice/ice_devlink.c @@ -250,8 +250,24 @@ ice_devlink_flash_update(struct devlink *devlink, struct device *dev = &pf->pdev->dev; struct ice_hw *hw = &pf->hw; const struct firmware *fw; + u8 preservation; int err; + if (!params->overwrite_mask) { + /* preserve all settings and identifiers */ + preservation = ICE_AQC_NVM_PRESERVE_ALL; + } else if (params->overwrite_mask == DEVLINK_FLASH_OVERWRITE_SETTINGS) { + /* overwrite settings, but preserve the vital device identifiers */ + preservation = ICE_AQC_NVM_PRESERVE_SELECTED; + } else if (params->overwrite_mask == (DEVLINK_FLASH_OVERWRITE_SETTINGS | + DEVLINK_FLASH_OVERWRITE_IDENTIFIERS)) { + /* overwrite both settings and identifiers, preserve nothing */ + preservation = ICE_AQC_NVM_NO_PRESERVATION; + } else { + NL_SET_ERR_MSG_MOD(extack, "Requested overwrite mask is not supported"); + return -EOPNOTSUPP; + } + if (!hw->dev_caps.common_cap.nvm_unified_update) { NL_SET_ERR_MSG_MOD(extack, "Current firmware does not support unified update"); return -EOPNOTSUPP; @@ -269,7 +285,7 @@ ice_devlink_flash_update(struct devlink *devlink, devlink_flash_update_begin_notify(devlink); devlink_flash_update_status_notify(devlink, "Preparing to flash", NULL, 0, 0); - err = ice_flash_pldm_image(pf, fw, extack); + err = ice_flash_pldm_image(pf, fw, preservation, extack); devlink_flash_update_end_notify(devlink); release_firmware(fw); @@ -278,6 +294,7 @@ ice_devlink_flash_update(struct devlink *devlink, } static const struct devlink_ops ice_devlink_ops = { + .supported_flash_update_params = DEVLINK_SUPPORT_FLASH_UPDATE_OVERWRITE_MASK, .info_get = ice_devlink_info_get, .flash_update = ice_devlink_flash_update, }; diff --git a/drivers/net/ethernet/intel/ice/ice_fw_update.c b/drivers/net/ethernet/intel/ice/ice_fw_update.c index 292d87b996ab..142123155a0f 100644 --- a/drivers/net/ethernet/intel/ice/ice_fw_update.c +++ b/drivers/net/ethernet/intel/ice/ice_fw_update.c @@ -625,6 +625,7 @@ static const struct pldmfw_ops ice_fwu_ops = { * ice_flash_pldm_image - Write a PLDM-formatted firmware image to the device * @pf: private device driver structure * @fw: firmware object pointing to the relevant firmware file + * @preservation: preservation level to request from firmware * @extack: netlink extended ACK structure * * Parse the data for a given firmware file, verifying that it is a valid PLDM @@ -638,7 +639,7 @@ static const struct pldmfw_ops ice_fwu_ops = { * Returns: zero on success or a negative error code on failure. */ int ice_flash_pldm_image(struct ice_pf *pf, const struct firmware *fw, - struct netlink_ext_ack *extack) + u8 preservation, struct netlink_ext_ack *extack) { struct device *dev = ice_pf_to_dev(pf); struct ice_hw *hw = &pf->hw; @@ -646,13 +647,24 @@ int ice_flash_pldm_image(struct ice_pf *pf, const struct firmware *fw, enum ice_status status; int err; + switch (preservation) { + case ICE_AQC_NVM_PRESERVE_ALL: + case ICE_AQC_NVM_PRESERVE_SELECTED: + case ICE_AQC_NVM_NO_PRESERVATION: + case ICE_AQC_NVM_FACTORY_DEFAULT: + break; + default: + WARN(1, "Unexpected preservation level request %u", preservation); + return -EINVAL; + } + memset(&priv, 0, sizeof(priv)); priv.context.ops = &ice_fwu_ops; priv.context.dev = dev; priv.extack = extack; priv.pf = pf; - priv.activate_flags = ICE_AQC_NVM_PRESERVE_ALL; + priv.activate_flags = preservation; status = ice_acquire_nvm(hw, ICE_RES_WRITE); if (status) { diff --git a/drivers/net/ethernet/intel/ice/ice_fw_update.h b/drivers/net/ethernet/intel/ice/ice_fw_update.h index 79472cc618b4..c6390f6851ff 100644 --- a/drivers/net/ethernet/intel/ice/ice_fw_update.h +++ b/drivers/net/ethernet/intel/ice/ice_fw_update.h @@ -5,7 +5,7 @@ #define _ICE_FW_UPDATE_H_ int ice_flash_pldm_image(struct ice_pf *pf, const struct firmware *fw, - struct netlink_ext_ack *extack); + u8 preservation, struct netlink_ext_ack *extack); int ice_check_for_pending_update(struct ice_pf *pf, const char *component, struct netlink_ext_ack *extack); |
