#!/bin/bash
# Function to display script usage
function print_usage() {
cat <<EOF
USAGE:
./update_config.sh <Mode> [<ServicesEnabled>] [<NumberCyInstances>] [<NumProcesses>] [<LimitDevAccess>]
DESCRIPTION:
Update the QAT device configuration file based on the provided input or default settings for either multi-process or multi-thread mode.
This step is applicable only for the Out-of-Tree (OOT) driver, as the in-tree driver does not require configuration files and is instead
managed through policy settings located in `/etc/sysconfig/qat`.
ARGUMENTS:
-h or -help:
Print usage help.
<Mode>:
multi_process: Configure for multi-process mode.
multi_thread: Configure for multi-thread mode.
<ServicesEnabled>:
QAT Gen4 devices (4xxx, 401x, 402x): 'asym;sym', 'asym', 'sym', 'asym;dc', or 'sym;dc' if compression co-exists.
Other lower QAT Gen (37c8): 'cy'.
<NumberCyInstances>:
Number of CyInstances to configure in the driver configuration file.
<NumProcesses>:
Number of processes to configure in the driver configuration file.
<LimitDevAccess>:
LimitDevAccess configuration in the driver configuration file. Acceptable values: [0, 1].
EXAMPLES:
./update_config.sh multi_process
./update_config.sh multi_thread
./update_config.sh multi_process asym 1 64 0
