* scsi: pm80xx: Set RETFIS when requested by libsasIgor Pylypiv2023-08-211-1/+1
| | | | | | | | | | | | By default PM80xx HBAs return FIS only when a drive reports an error. The RETFIS bit forces the controller to populate FIS even when a drive reports no error.

* scsi: pm80xx: Handle non-fatal errorsAjish Koshy2022-02-281-2/+7
| | | | | | | | | | | | | | | | | | | | | | | Firmware expects host driver to clear scratchpad rsvd 0 register after non-fatal error is found. This is done when firmware raises fatal error interrupt and indicates non-fatal error. At this point firmware updates scratchpad rsvd 0 register with non-fatal error value. Here host has to clear the register after reading it during non-fatal errors. Rename: - MSGU_HOST_SCRATCH_PAD_6 to MSGU_SCRATCH_PAD_RSVD_0 - MSGU_HOST_SCRATCH_PAD_7 to MSGU_SCRATCH_PAD_RSVD_1 Link: https://lore.kernel.org/r/20220222092618.108198-1-Ajish.Koshy@microchip.com Reviewed-by: Damien Le Moal <damien.lemoal@opensource.wdc.com> Acked-by: Jack Wang <jinpu.wang@ionos.com> Signed-off-by: Ajish Koshy <Ajish.Koshy@microchip.com> Signed-off-by: Viswas G <Viswas.G@microchip.com> Signed-off-by: Martin K.

* scsi: pm8001: Fix use of struct set_phy_profile_req fieldsDamien Le Moal2022-02-231-1/+1
| | | | | | | | | | | | | | In mpi_set_phy_profile_req() and pm8001_set_phy_profile_single(), use cpu_to_le32() to initialize the ppc_phyid field of struct set_phy_profile_req. Furthermore, fix the definition of the reserved field of this structure to be an array of __le32, to match the use of cpu_to_le32() when assigning values. These changes remove several sparse type warnings.

* scsi: pm8001: Fix bogus FW crash for maxcpus=1John Garry2022-01-251-1/+5
| | | | | | | | | | | | | | | | | | | | | | According to the comment in check_fw_ready() we should not check the IOP1_READY field in register SCRATCH_PAD_1 for 8008 or 8009 controllers. However we check this very field in process_oq() for processing the highest index interrupt vector. The highest interrupt vector is checked as the FW is programmed to signal fatal errors through this irq. Change that function to not check IOP1_READY for those mentioned controllers, but do check ILA_READY in both cases. The reason I assume that this was not hit earlier was because we always allocated 64 MSI(X), and just did not pass the vector index check in process_oq(), i.e. the handler never ran for vector index 63.

* scsi: pm80xx: Do not busy wait in MPI init checkakshatzen2021-01-131-2/+2
| | | | | | | | | | | | | | | We do not need to busy wait during mpi_init_check() since it is not being invoked in atomic context. mpi_init_check() is being called from pm8001_pci_resume(), pm8001_pci_probe(). Hence we are replacing udelay with msleep.

* scsi: pm80xx: Avoid busywait in FW ready checkakshatzen2020-11-051-0/+6
| | | | | | | | | | | | | | | | | | | | In function check_fw_ready() we busy wait using udelay. The CPU is not released and we see need_resched failures. Busy waiting is not necessary since we are in process context and we can sleep instead. Replace udelay with msleep of 20 ms intervals while waiting for firmware to become ready. It has been verified that check_fw_ready is not being used in interrupt context anywhere, hence it is safe to make this change.
