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