NAME
accel-config-config-wq - configure individual attributes of a work queueSYNOPSIS
accel-config config-wq <device name>/<wq name> [<options>]
EXAMPLE
accel-config config-wq dsa0/wq0.0 --wq-size=16OPTIONS
-g, --group-id=specify the group id used by work queue, group
id should be between 0 and the maximum number of groups per device. A group id
of -1 disassociates the work queue from a group.
-s, --wq-size=
specify work queue size used by a work queue.
The wq-size should be between 0 and the maximum workqueue size exposed by the
device in the max_work_queue_size attribute under device.
-p, --priority
specify the priority of this work queue
relative to other work queues in the same group. This field ranges from 1 to
15 where the larger value means higher priority. For example, if wq1 has a
priority of 6 and wq2 has priority of 2, wq1 will issue 3 times as many
descriptors to the engine compare to wq2.
-b, --block-on-fault
toggle block on fault enable for the work
queue. block-on-fault should be either 0 or 1. If block on fault is disabled,
if a page fault occurs on a source or destination memory access, the operation
stops and the page fault is reported to the software.
-t, --threshold
configure the threshold for the wq. The set up
threshold value should be larger than 0 and only for "shared" wq,
and note that the configured threshold value should be at least 1 less than
the configured wq-size value. The reason is threshold is set for unprivileged
users, and need to reserve at least 1 space for the privileged user for
commands.
-y, --type
configure the type for the wq. The wq type can
be "kernel" for kernel user case to request wq or "user"
for regular character device driver use case to wq.
-n, --name
configure the name for the wq. This can be any
string defined by the user. Typically it is used for identifying the wq in
some unique way. A possible suggestion would be using a uuid string.
-d, --driver-name
specify the name of the driver to bind. This
should be one of the valid wq drivers found in /sys/bus/dsa/drivers
-m, --mode
configure the mode for the wq. The wq mode can
be set as "dedicated" or "shared".
-c, --max-batch-size
specify the max batch size used by a work
queue. The value should be between 1 and the device maximum batch size found
in the max_batch_size attribute under device. If the value is not a power of
2, it will be rounded up to the next power of 2.
-x, --max-transfer-size
specify the max transfer size used by a work
queue. The value should be between 1 and the device maximum transfer size
found in the max_transfer_size attribute under device. If the value is not a
power of 2, it will be rounded up to the next power of 2.
-a, --ats-disable
toggle whether ATS disable is turned on for
the work queue. The value should be either 0 or 1. 0 indicates ATS is on, and
1 indicates ATS is off for the work queue.
