Modified files:
sys/dev/isp isp_freebsd.c isp_freebsd.h
Log:
Add get/set param ioctl support.
Remove sim queue freezes for resource shortages. I've had too many
strange race conditions where I freeze on a resource shortage but
never get unfrozen.
Consolidate the remaining sim queue freeze condition (for loopdown)
into an inline with debug messages that allows us to track problems
at ISP_LOGDEBUG0 level easier. Change a bunch of debug messages about
loop down/up conditions to ISP_LOGDEBUG0 level.
Remove dead isp_relsim code.
Change some internal flag stuff for efficiency.
Complain vociferously if we try and use our FC scratch area while it's
busy being used already (I mean, if we don't have solaris' ability
to sleep as an interrupt thread which would allow us to just use
a p/v semaphore, at least *say* when you've just borked yourself).
Add infrastructure to allow overrides of hard loopid && initiator
id from boot variables.
Fix the usual quota of silly bugs:
+ 'ktmature' needs to be per-instance. Argh.
+ When entering isp_watchdog, set intsok to zero, preserving
old value to restore later. It's not nice to try and sleep
from splsoftclock.
+ Fix tick overflow buglet in checking timeout value.
