2020-04-20cxgb4: fix large delays in PTP synchronizationRahul Lakkireddy
Fetching PTP sync information from mailbox is slow and can take up to 10 milliseconds. Reduce this unnecessary delay by directly reading the information from the corresponding registers. Fixes: 9c33e4208bce ("cxgb4: Add PTP Hardware Clock (PHC) support") Signed-off-by: Manoj Malviya <manojmalviya@chelsio.com> Signed-off-by: Rahul Lakkireddy <rahul.lakkireddy@chelsio.com> Signed-off-by: David S.

2020-03-25cxgb4: Add support to catch bits set in INT_CAUSE5Rahul Kundu
This commit adds support to catch any bits set in SGE_INT_CAUSE5 for Parity Errors. F_ERR_T_RXCRC flag is used to ignore that particular bit as it is not considered as fatal. So, we clear out the bit before looking for error. This patch now read and report separately all three registers(Cause1, Cause2, Cause5). Also, checks for errors if any.

2019-05-22cxgb4: Enable hash filter with offloadVishal Kulkarni
Hash (exact-match) filters used for offloading flows share the same active region resources on the chip with upper layer drivers, like iw_cxgb4, chcr, etc. Currently, only either Hash filters or ULDs can use the active region resources, but not both. Hence, use the new firmware configuration parameters (when available) to allow both the Hash filters and ULDs to share the active region simultaneously.

2018-05-16cxgb4: update LE-TCAM collection for T6Rahul Lakkireddy
For T6, clip table is separated from main TCAM. So, update LE-TCAM collection logic to collect clip table TCAM as well. IPv6 takes 4 entries in clip table TCAM compared to 2 entries in main TCAM. Also, in case of errors, keep LE-TCAM collected so far and set the status to partial dump.

2017-01-16cxgb4: Shutdown adapter if firmware times out or errors outHariprasad Shenai
Perform an emergency shutdown of the adapter and stop it from continuing any further communication on the ports or DMA to the host. This is typically used when the adapter and/or firmware have crashed and we want to prevent any further accidental communication with the rest of the world. This will also force the port Link Status to go down -- if register writes work -- which should help our peers figure out that we're down.
