From: Jacob Keller <[email protected]> The TS_LL_READ macros are used as part of the low latency Tx timestamp interface. A future firmware extension will add support for performing PHY timer updates over this interface. Using TS_LL_READ as the prefix for these macros will be confusing once the interface is used for other purposes.
Rename the macros, using the prefix REG_LL_PROXY_H, to better clarify that this is for the low latency interface. Additionally add macroses for PF_SB_ATQBAH and PF_SB_ATQBAL registers to better clarify content of this registers as PF_SB_ATQBAH contain low part of Tx timestamp Co-developed-by: Karol Kolacinski <[email protected]> Signed-off-by: Karol Kolacinski <[email protected]> Signed-off-by: Jacob Keller <[email protected]> Reviewed-by: Milena Olech <[email protected]> Signed-off-by: Anton Nadezhdin <[email protected]> --- drivers/net/ethernet/intel/ice/ice_ptp.c | 14 +++++++------- drivers/net/ethernet/intel/ice/ice_ptp_hw.c | 14 +++++++------- drivers/net/ethernet/intel/ice/ice_ptp_hw.h | 13 ++++++++----- 3 files changed, 22 insertions(+), 19 deletions(-) diff --git a/drivers/net/ethernet/intel/ice/ice_ptp.c b/drivers/net/ethernet/intel/ice/ice_ptp.c index d8ed4240f225..3c81d98883c0 100644 --- a/drivers/net/ethernet/intel/ice/ice_ptp.c +++ b/drivers/net/ethernet/intel/ice/ice_ptp.c @@ -499,9 +499,9 @@ void ice_ptp_req_tx_single_tstamp(struct ice_ptp_tx *tx, u8 idx) ice_trace(tx_tstamp_fw_req, tx->tstamps[idx].skb, idx); /* Write TS index to read to the PF register so the FW can read it */ - wr32(&pf->hw, PF_SB_ATQBAL, - TS_LL_READ_TS_INTR | FIELD_PREP(TS_LL_READ_TS_IDX, idx) | - TS_LL_READ_TS); + wr32(&pf->hw, REG_LL_PROXY_H, + REG_LL_PROXY_H_TS_INTR_ENA | FIELD_PREP(REG_LL_PROXY_H_TS_IDX, idx) | + REG_LL_PROXY_H_EXEC); tx->last_ll_ts_idx_read = idx; } @@ -528,20 +528,20 @@ void ice_ptp_complete_tx_single_tstamp(struct ice_ptp_tx *tx) ice_trace(tx_tstamp_fw_done, tx->tstamps[idx].skb, idx); - val = rd32(&pf->hw, PF_SB_ATQBAL); + val = rd32(&pf->hw, REG_LL_PROXY_H); /* When the bit is cleared, the TS is ready in the register */ - if (val & TS_LL_READ_TS) { + if (val & REG_LL_PROXY_H_EXEC) { dev_err(ice_pf_to_dev(pf), "Failed to get the Tx tstamp - FW not ready"); return; } /* High 8 bit value of the TS is on the bits 16:23 */ - raw_tstamp = FIELD_GET(TS_LL_READ_TS_HIGH, val); + raw_tstamp = FIELD_GET(REG_LL_PROXY_H_TS_HIGH, val); raw_tstamp <<= 32; /* Read the low 32 bit value */ - raw_tstamp |= (u64)rd32(&pf->hw, PF_SB_ATQBAH); + raw_tstamp |= (u64)rd32(&pf->hw, REG_LL_PROXY_L); /* Devices using this interface always verify the timestamp differs * relative to the last cached timestamp value. diff --git a/drivers/net/ethernet/intel/ice/ice_ptp_hw.c b/drivers/net/ethernet/intel/ice/ice_ptp_hw.c index b9cf8ce9644a..06a0c78cd491 100644 --- a/drivers/net/ethernet/intel/ice/ice_ptp_hw.c +++ b/drivers/net/ethernet/intel/ice/ice_ptp_hw.c @@ -4871,23 +4871,23 @@ ice_read_phy_tstamp_ll_e810(struct ice_hw *hw, u8 idx, u8 *hi, u32 *lo) u8 err; /* Write TS index to read to the PF register so the FW can read it */ - val = FIELD_PREP(TS_LL_READ_TS_IDX, idx) | TS_LL_READ_TS; - wr32(hw, PF_SB_ATQBAL, val); + val = FIELD_PREP(REG_LL_PROXY_H_TS_IDX, idx) | REG_LL_PROXY_H_EXEC; + wr32(hw, REG_LL_PROXY_H, val); /* Read the register repeatedly until the FW provides us the TS */ - err = rd32_poll_timeout_atomic(hw, PF_SB_ATQBAL, val, - !FIELD_GET(TS_LL_READ_TS, val), - 10, TS_LL_READ_TIMEOUT); + err = rd32_poll_timeout_atomic(hw, REG_LL_PROXY_H, val, + !FIELD_GET(REG_LL_PROXY_H_EXEC, val), + 10, REG_LL_PROXY_H_TIMEOUT_US); if (err) { ice_debug(hw, ICE_DBG_PTP, "Failed to read PTP timestamp using low latency read\n"); return err; } /* High 8 bit value of the TS is on the bits 16:23 */ - *hi = FIELD_GET(TS_LL_READ_TS_HIGH, val); + *hi = FIELD_GET(REG_LL_PROXY_H_TS_HIGH, val); /* Read the low 32 bit value and set the TS valid bit */ - *lo = rd32(hw, PF_SB_ATQBAH) | TS_VALID; + *lo = rd32(hw, REG_LL_PROXY_L) | TS_VALID; return 0; } diff --git a/drivers/net/ethernet/intel/ice/ice_ptp_hw.h b/drivers/net/ethernet/intel/ice/ice_ptp_hw.h index 4c059e2f4d96..71097eb67d54 100644 --- a/drivers/net/ethernet/intel/ice/ice_ptp_hw.h +++ b/drivers/net/ethernet/intel/ice/ice_ptp_hw.h @@ -694,11 +694,14 @@ static inline bool ice_is_dual(struct ice_hw *hw) #define BYTES_PER_IDX_ADDR_L 4 /* Tx timestamp low latency read definitions */ -#define TS_LL_READ_TIMEOUT 2000 -#define TS_LL_READ_TS_HIGH GENMASK(23, 16) -#define TS_LL_READ_TS_IDX GENMASK(29, 24) -#define TS_LL_READ_TS_INTR BIT(30) -#define TS_LL_READ_TS BIT(31) +#define REG_LL_PROXY_H_TIMEOUT_US 2000 +#define REG_LL_PROXY_H_TS_HIGH GENMASK(23, 16) +#define REG_LL_PROXY_H_TS_IDX GENMASK(29, 24) +#define REG_LL_PROXY_H_TS_INTR_ENA BIT(30) +#define REG_LL_PROXY_H_EXEC BIT(31) + +#define REG_LL_PROXY_L PF_SB_ATQBAH +#define REG_LL_PROXY_H PF_SB_ATQBAL /* Internal PHY timestamp address */ #define TS_L(a, idx) ((a) + ((idx) * BYTES_PER_IDX_ADDR_L_U)) -- 2.42.0
