too (otherwise the chain won't work).
(2) If NO_WRKDIR is set, "make clean" removes "./.*_done" (assuming
these are cookies...or should I list all the cookies?)
through the use of the config file flags as opposed to the option
"NSECS_MULTI". "NSECS_MULTI" has been removed from the driver.
The new capability allows boot-time modification of the config.
I made the changes I sent you before. In the interests of cleanliness, I made
modifications to /sys/i386/isa/tw.c to kill the warnings and make it compile
clean. While I was at it, I also made a bunch of internal functions static.

flags parameter to all xxstart routines so that the correct information can
be passed down into the device specific routines. This is needed to ensure
that ccb/scb allocation routines don't hang.

higher level scsi code.
Spls should never be conditionalized, so don't do so here.
Restructure the get_scb routine so that we can't get into an infinite
loop if the ccbs are exhausted and we are are called with SCSI_NOSLEEP set.
Other driver maintainer's that based their scb allocation routines on Julian's
code should look at these changes and implement them for their driver.
The aic7xxx driver inspired these changes because early revs of the
aic7770 chips have so few SCBs that you can actually run out. If you
have a rev C or aic7770 (as is reported by the driver probe) and had more
than 2 drives, you could get into an infinite loop when using up all of
the SCBs. Since the driver will only allow two SCBs per device and I
only had two devices, I never saw this problem on my Rev C card.
Bzero only 19 bytes of the scb instead of 2k (ack!). This was a hold
over from when a struct SCB only contained the information downloaded
to the board, but we now store kernel driver data in there as well. This
greatly lowers the overhead for small transactions (I get ~1MB/sec for
dds with a 512 byte block size).

incomplete declarations here any more. Some things depend on
incomplete declarations elsewhere. The `offset' arg to d_mmap_t is
bogus (it is `int' but should be `vm_offset_t') but it is what the
driver mmap functions actually accept, although they are passed a
`vm_offset_t'.
Function declararions in headers should always be complete to avoid
warnings from `gcc -Wstrict-prototypes' for compiling modules that
don't even use the offending declarations.
don't expect this to work yet.. but at least they're here..
(hey this cvs stuff is fun!)
activate with a line exactly like the isa line in the config file,
(but specifying eisa :)
patches to come..
Headers should always use `__inline' for inline functions to avoid
syntax errors when modules that don't even use the offending functions
are compiled with `gcc -ansi'.
We now have RELEASE=CURRENT in the CVS-tree.
If this hasn't been edited, we will use "BUILT-yyyymmdd" where the time is
that of the compile, and leave it at that, we can't do any better.
If there is no serious objections, I will modify the "cvs co" script on
freefall to fiddle this file after checkout so that it becomes
CURRENT-yyyymmdd, where the time is that of the checkout.
