+7. Debugging
+
+The module kernelcapi has a module parameter showcapimsgs controlling some
+debugging output produced by the module. It can only be set when the module is
+loaded, via a parameter "showcapimsgs=<n>" to the modprobe command, either on
+the command line or in the configuration file.
+
+If the lowest bit of showcapimsgs is set, kernelcapi logs controller and
+application up and down events.
+
+In addition, every registered CAPI controller has an associated traceflag
+parameter controlling how CAPI messages sent from and to tha controller are
+logged. The traceflag parameter is initialized with the value of the
+showcapimsgs parameter when the controller is registered, but can later be
+changed via the MANUFACTURER_REQ command KCAPI_CMD_TRACE.
+
+If the value of traceflag is non-zero, CAPI messages are logged.
+DATA_B3 messages are only logged if the value of traceflag is > 2.
+
+If the lowest bit of traceflag is set, only the command/subcommand and message
+length are logged. Otherwise, kernelcapi logs a readable representation of
+the entire message.

 /* hardirq.h: PA-RISC hard IRQ support.
  *
  * Copyright (C) 2001 Matthew Wilcox <matthew@wil.cx>
- *
- * The locking is really quite interesting.  There's a cpu-local
- * count of how many interrupts are being handled, and a global
- * lock.  An interrupt can only be serviced if the global lock
- * is free.  You can't be sure no more interrupts are being
- * serviced until you've acquired the lock and then checked
- * all the per-cpu interrupt counts are all zero.  It's a specialised
- * br_lock, and that's exactly how Sparc does it.  We don't because
- * it's more locking for us.  This way is lock-free in the interrupt path.
