SMARTPQI(4) amd64 Kernel Interfaces Manual SMARTPQI(4) NAME smartpqi -- Microchip Smart Storage SCSI driver SYNOPSIS To compile this driver into the kernel, place these lines in the kernel configuration file: device pci device scbus device smartpqi The driver can be loaded as a module at boot time by placing this line in loader.conf(5): smartpqi_load="YES" DESCRIPTION The smartpqi driver provides support for Microchip Technology Inc. / Adaptec SmartRaid and SmartHBA SATA/SAS/NVMe PCIe controllers HARDWARE Controllers supported by the smartpqi driver include, but not limited to: * HPE Gen10 Smart Array Controller Family * Adaptec SmartRaid and SmartHBA Controllers * OEM Controllers based on the Microchip Technology Inc. SmartROC and SmartIOC Chipsets DEBUGGING Driver diagnostic printing is controlled in loader.conf(5) by using the global hw.smartpqi.debug_level tunable. The debug_level variable is set with an integer value. The default value is 0x0060 (warn && error). The following levels are available: Flag Name Description 0x0001 init System initialization operations 0x0002 info Basic information 0x0004 function Used to show function entry and exit 0x0008 io Logging data from controller 0x0010 discovery Device discovery 0x0020 warning Operational warnings 0x0040 error Parameter errors and programming bugs 0x0080 note More detailed information DEVICE HINTS The following tunable values can be set in /boot/device.hints to control the behavior of the smartpqi driver. These hints are specified as: hint.smartpqi.<unit>.<variable>=<value> The supported variables are: stream_disable If set to 0, disables Stream Detection. Default is (enabled). sata_unique_wwn_disable If set to 0, disables SATA Unique World Wide Num- ber. Default is (enabled). aio_raid1_write_disable If set to 0, disables acceleration of RAID1 writes Default is (enabled). aio_raid5_write_disable If set to 0, disables acceleration of RAID5 writes Default is (enabled). aio_raid6_write_disable If set to 0, disables acceleration of RAID6 writes Default is (enabled). queue_depth Sets queue depth for the controller. If the queue depth value is greater than the maximum supported queue size of the driver or controller, it will be set to the lowest size. If the queue depth value is lower than the minimum queue depth then this will be set to the minimum queue depth. Default is driver-determined. sg_count Sets the scatter gather (sg) count. If this sg count is greater than maximum sg count it will be set to the maximum sg count. If this sg count is less than minimum sg count it will be set to the minimum sg count. Default is driver-determined. For example, to disable Stream Detection on the first controller, add the following line to /boot/device.hints: hint.smartpqi.0.stream_disable="0" FILES /dev/smartpqi? smartpqi management interface NOTES Configuration To configure a Microchip Smart Storage controller, refer to the User Guide for the controller, which can be found by searching for the specific con- troller at https://www.microchip.com/design-centers/storage SEE ALSO kld(4), linux(4), pass(4), scsi(4), xpt(4), loader.conf(5), camcontrol(8), kldload(8) HISTORY The smartpqi driver first appeared in FreeBSD 11.1.
