This function will be used by the drivers during init to check whether the FW is in recovery mode or not. If FW is in recovery mode then the drivers need to run in a recovery mode where it can allow only limited operations. Link should be down, allow only certain AQ commands etc. Signed-off-by: Victor Raj Signed-off-by: Paul M Stillwell Jr Signed-off-by: Qi Zhang --- drivers/net/ice/base/ice_common.c | 15 +++++++++++++++ drivers/net/ice/base/ice_common.h | 8 ++++++++ 2 files changed, 23 insertions(+) diff --git a/drivers/net/ice/base/ice_common.c b/drivers/net/ice/base/ice_common.c index c35a2f91d..2ebf95eed 100644 --- a/drivers/net/ice/base/ice_common.c +++ b/drivers/net/ice/base/ice_common.c @@ -3915,3 +3915,18 @@ ice_sched_query_elem(struct ice_hw *hw, u32 node_teid, ice_debug(hw, ICE_DBG_SCHED, "query element failed\n"); return status; } + +/** + * ice_is_fw_in_rec_mode + * @hw: pointer to the HW struct + * + * This function returns true if fw is in recovery mode + */ +bool ice_is_fw_in_rec_mode(struct ice_hw *hw) +{ + u32 reg; + + /* check the current FW mode */ + reg = rd32(hw, GL_MNG_FWSM); + return (reg & GL_MNG_FWSM_FW_MODES_M) > ICE_FW_MODE_DBG; +} diff --git a/drivers/net/ice/base/ice_common.h b/drivers/net/ice/base/ice_common.h index cc7a77747..9665f3204 100644 --- a/drivers/net/ice/base/ice_common.h +++ b/drivers/net/ice/base/ice_common.h @@ -10,6 +10,13 @@ #include "ice_flex_pipe.h" #include "ice_switch.h" +enum ice_fw_modes { + ICE_FW_MODE_NORMAL, + ICE_FW_MODE_DBG, + ICE_FW_MODE_REC, + ICE_FW_MODE_DBG_REC +}; + enum ice_status ice_nvm_validate_checksum(struct ice_hw *hw); void @@ -188,4 +195,5 @@ ice_stat_update32(struct ice_hw *hw, u32 reg, bool prev_stat_loaded, enum ice_status ice_sched_query_elem(struct ice_hw *hw, u32 node_teid, struct ice_aqc_get_elem *buf); +bool ice_is_fw_in_rec_mode(struct ice_hw *hw); #endif /* _ICE_COMMON_H_ */
