NAME

       accel-config-config-wq - configure individual attributes of a work queue

SYNOPSIS

       accel-config config-wq <device name>/<wq name> [<options>]

EXAMPLE

       accel-config config-wq dsa0/wq0.0 --wq-size=16

OPTIONS

       -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.
