17 * debug level can be programmed on the fly via SysFS (hex values)
18 *
19 * Example: (programming for MPT_DEBUG_EVENTS on host 5)
20 *
21 * echo 8 > /sys/class/scsi_host/host5/debug_level
22 *
23 * --------------------------------------------------------
24 * mpt_debug_level - command line parameter
25 * this allow enabling debug at driver load time (for all iocs)
26 *
27 * Example (programming for MPT_DEBUG_EVENTS)
28 *
29 * insmod mptbase.ko mpt_debug_level=8
30 *
31 * --------------------------------------------------------
32 * CONFIG_FUSION_LOGGING - enables compiling debug into driver
33 * this can be enabled in the driver Makefile
34 *
35 *
36 * --------------------------------------------------------
37 * Please note most debug prints are set to logging priority = debug
38 * This is the lowest level, and most verbose. Please refer to manual
39 * pages for syslogd or syslogd-ng on how to configure this.
