  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.
