I would like to ask if below change is safe (I'm considering to do
that change on iwlegacy):
diff --git a/drivers/net/wireless/iwlwifi/pcie/rx.c b/drivers/net/wireless/iwlwifi/pcie/rx.c
index 567e67a..1ebdb83 100644
--- a/drivers/net/wireless/iwlwifi/pcie/rx.c
+++ b/drivers/net/wireless/iwlwifi/pcie/rx.c
@@ -183,7 +183,7 @@ static void iwl_pcie_rxq_inc_wr_ptr(struct iwl_trans *trans, struct iwl_rxq *q)
} else {
/* Device expects a multiple of 8 */
q->write_actual = (q->write & ~0x7);
- iwl_write_direct32(trans, FH_RSCSR_CHNL0_WPTR,
+ iwl_write32(trans, FH_RSCSR_CHNL0_WPTR,
q->write_actual);
}
}
This register seems to be only read by firmware, so maybe we can modify
it without grab nic access. We are doing that on
iwl_pcie_txq_inc_wr_ptr().
