Add a test against isp->isp_osinfo.islocked prior to trying to see
whether --isp->isp_osinfo.islocked is zero to cause us to unlock
(non-SMPLOCK case).
compile time will build in mutex locks, otherwise the old locking (splcam/splx
with a recursion counter) will be compiled in.
We still depend on config_intr_hook to tell us when it's okay to call
msleep instead of polling. It'd be real nice if we could do this early
enough to not hang up a machine struggling with a bad Fibre Channel loop,
but that's still to come.
quite a bit so that all of the ports have a similar set of required
macros/definitions (and in similar places in the isp_<platform>.h
file).
Some new macros/functions added- Mailbox Acquire/Relase macros,
NANOTIME macros, SNPRINTf and STRNCAT. MemoryBarrier beomes
MEMORYBARRIER with much stronger types.
to isp_osinfo substructure (all in prep for SMP). Define MBOX_WAIT_COMPLETE
and MBOX_NOTIFY_COMPLETE macros so that we can now (temp) use tsleep
to wait for mailbox completion. Requires us to guess whether we're
servicing an interrupt or not- will use intr_nesting_level.
Add local strncat function.
store a bitmask of whether we've set a value into ccb->ccb_h.status,
whether we're in the watchdog routine for this command now, whether
we've set a grace period for this command and whether this command is
actually done.
See comments of rev 1.45 of isp.c for more complete information.
(we always support fabric now). Remove SCCLUN definition (we always
support SCCLUN now, if we load the f/w). Add typedef definition of an
external firmware fetch function.
Add in null SWIZZLE definitions. Add in CFGPRINTF define. Change default
debug level to refer to an external isp_debug variable. Remove inline
functions as they're now in isp_inline.h and include that file.
thwank in register layout goop). A different mboxcmd approach. Some PDB change
infrastructure. Some better management of loopdown/loopup events (keep them
distinct from resource starvation for simq freeze/unfreeze actions).
the startup code. Implement a call to outer framework function so that
asynchronous events can be handled (e.g., speed negotiation, target mode).
Roll internal release tags.
