code gratefully borrowed from Patrick Stirling who did a lot of the
grunt work on this years ago. There are also some beginnings of
swizzle macros in case we go to a big endian machine. This is just
a first pass at this and is likely to change a bit over the next
Add in a very large amount of target mode support code- this is just
a first pass at this. It's a difficult thing because some of the code
can be in platform independent areas (see isp_target.?) but a lot has
to be in platform dependent areas because of not only the tight coupling
of received commands/events and the specific OS subsystem but because
the platform independent code has (deliberately) no event/wait mechanisms.
of where we could have seen the loop up at least once so it
makes sense. Change some stuff in ispscsicmd so we don't get
stuck there if the loop has never come up yet. Add in some
target mode support code.
of queue entries have to be at least 16 bits now! If we're running
a 2100 less than rev 5, turn off loop fairness (per Qlogic errata). Fix
typo in checking against 2200 F/W revision. Slightly fix/reorder fabric
login stuff. Change to usage of isp_getrqentry for code clarity. Add some
defensive dual bus assumptions. Various cleanups, etc...
Role the core version minor number. Change the arguments to the dma
setup function to use a u_int16_t for the output request loop pointer
(truly amazing that this hasn't blown up in anyones face so far). Do
some shuffling around of some items.
by Qlogic. The firmware is now also kept from compiling by default
unless some config options are set.
While we're at it, roll the 2200 f/w to 2.01.0. Still need to get the
1.17.26 2100 f/w working as it solves a lot of problems but it doesn't
want to work yet with this driver (:-)).
out of the PCI CLASS reg and store it in the softc. Use the getenv_quad
function to get a WWN override from the environment. Look for a config
value for same. Make slightly less lame the wwn seed construction.
have you is prototyped). Removed code versions in md struct- not used
any more. Allocate transfer dma maps and xflist stuff in mbxdmasetup based
upon isp->isp_maxcmds. Allow for multiple calls to mbxdmasetup (for
isp_reset cases).
file later. Do some pencil-sharpening types of minor changes. Change
how active commands are remembered (using new inline functions to get
handles, etc..). Now do a GET FIRMWARE STATUS after firing up the f/w as
outgoing mailbox 2 will tell you the f/w's notion of the max commands
that can be supported. Attempt to retrieve loop topology. Add in the
appropriate SWIZZLE/UNSWIZZLE macros calls (this is a no-op on Little
Endian machines but is needed for sparc (on other platforms)). Move
the temp port database we use to find out where things have moved to
after a LIP to the softc and off the kernel stack. Follow Qlogic's
hint and don't bother setting a tag for commands that don't have
this enabled (presumably the f/w will do it's own selection then).
Use an INT_PENDING macro to check for an interrupt. The call to
ISP_DMAFREE now just takes the handle- not the 'handle-1' which was
a layering violation. Use CFGPRINTF in a couple of places to make
things less chatty if not booting verbose, or CAMDEBUG compiles, etc..
where it defaults to one. Change simq width allocation to the max number
of commands supported by the HBA after f/w fires up- not the constant
MAXISPREQUEST value. Do some stylistic changes.
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.
the result queue length is never less than 64. Move (ick) temp port
database used for post-LIP merging off the kernel stack and put it
into the softc. Remove some target mode stuff which will come back
later in a different file. Change how the list of outstanding commands
are stored (now allocated at mailbox setup time to be just enough for
the max for a specific HBA which can vary). Keep a rotating seed of
the last index for this in the softc. Increase the count of active
commands from 10 to 16 bits.
