NAME

qatmgr − QAT resource manager

SYNOPSIS

qatmgr [option]…

DESCRIPTION

qatmgr is a daemon that manages QAT resources for the Intel© Quick Assist Technology (Intel© QAT) user space library (qatlib).

OPTIONS

−d, −−debug=LEVEL

set debug level, default 0 for no debug. Higher debug level produces more output.

−f, −−foreground

run in the foreground. By default, the qatmgr runs as a daemon in the background.

−h, −−help

display help page

−p, −−policy=POLICY

selects the QAT manager policy. This determines how resources should be allocated to each process using the qatlib library. The default POLICY 0 allocates one virtual function (VF) from each physical function (PF) endpoint to each process. This should be selected for best performance. A POLICY of 1 allocates a single VF to each process. This should be selected for maximum scalability. Any other POLICY value allocates that number of VFs to each process.
