This patchset introduces support to abort certain commands which have failed and retry. Certain errors require that the command be retried, like TRANS_TX_CREDIT_TIMEOUT_ERR in v1 hw. However, when these errors occur the IO may still be in the device, so the IO must first be aborted, and then retried. The HiSilicon SAS controller has no FW to do this work, so it needs to be done manually. Differences to v1: - check for tmf success result removed - remove query for task prior to abort - add flag to slot structure for task abort - add removal of superflous debug statement John Garry (6): hisi_sas: change tmf func complete check hisi_sas: add hisi_sas_slot_abort() hisi_sas: use slot abort in v1 hw hisi_sas: use slot abort in v2 hw hisi_sas: add hisi_sas_slave_configure() hisi_sas: update driver version to 1.3 drivers/scsi/hisi_sas/hisi_sas.h | 4 ++- drivers/scsi/hisi_sas/hisi_sas_main.c | 59 ++++++++++++++++++++++++++++++++-- drivers/scsi/hisi_sas/hisi_sas_v1_hw.c | 13 ++++++++ drivers/scsi/hisi_sas/hisi_sas_v2_hw.c | 15 +++++++-- 4 files changed, 85 insertions(+), 6 deletions(-) -- 1.9.1 -- To unsubscribe from this list: send the line "unsubscribe linux-scsi" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
