Manual Pages  — QAT

In order to load the driver on boot add these lines to loader.conf(5) selecting firmware(s) suitable for installed device(s)

	qat_200xx_fw_load="YES"
	qat_c3xxx_fw_load="YES"
	qat_c4xxx_fw_load="YES"
	qat_c62x_fw_load="YES"
	qat_dh895xcc_fw_load="YES"
	qat_4xxx_fw_load="YES"
	qat_load="YES"

A complete API for offloading these operations is exposed in the kernel and may be used by any other entity directly. In addition to exposing a complete kernel API for offloading cryptography and compression operations, the qat driver also integrates with crypto(4), allowing offloading supported operations to Intel QuickAssist Technology devices.

The specific device needs to be in the "down" state before changing the configuration.

dev.qat.X.state
	Show or set current state of the device. Possible values: "down", "up". NOTE: If the symmetric services are used for device the qat_ocf driver needs to be disabled prior the device reconfiguration.
dev.qat_ocf.0.enable
	Enable/disable the QAT cryptographic framework connectivity. Enabled by default.
dev.qat.X.cfg_services
	Override the device services enabled, may be one of: symmetric, asymmetric, data compression. Possible values: "sym", "asym", "dc", "sym;dc", "asym;dc", "sym;asym". Default services configured are "sym;asym" for even and "dc" for odd devices.
dev.qat.X.cfg_mode
	Override the device mode configuration for kernel space and user space instances. Possible values: "ks", "us", "ks;us". Default value "ks;us".
dev.qat.X.num_user_processes
	Override the number of uio user space processes that can connect to the QAT device. Default: 2

The following sysctl(8) variables are read-only:

dev.qat.X.frequency
	QAT device frequency value.
dev.qat.X.mmp_version
	QAT MMP Library revision number.
dev.qat.X.hw_version
	QAT hardware revision number.
dev.qat.X.fw_version
	QAT firmware revision number.
dev.qat.X.dev_cfg
	Summary of device specific configuration.
dev.qat.X.heartbeat
	QAT device heartbeat status. Value '1' indicates that the device is operational. Value '0' means that the device is not responsive. Device requires restart.
dev.qat.X.heartbeat_failed
	Number of QAT heartbeat failures received.
dev.qat.X.heartbeat_sent
	Number of QAT heartbeat requests sent.
