| Subject | [PATCH 11/15] hisi_sas: fix HBA SAS addr endianness for v1 hw |
| Message-ID | <seqtY-3JB-43@gated-at.bofh.it> |
The endianness for the SAS address in the TX_ID_DWORD registers is set incorrectly. We see errors like this in the boot log for v2 hw (which would have the same issue as v1 hw): [ 7.583284] sas: target proto 0x0 at 50000d1108e7923f:0x1f not handled This is due to the host SAS addr not matching the PHY SAS addr in the expander host-attached phy discovery responses. To fix, we byte swap the SAS addr from BE to LE (which is the endianness of the SAS controller).
