in libc, we can get rid of the private/special copies of yp_*.c
files and rpcgen them at compile time instead. This leaves us with
just one unique source files: yppush.c
so that these ioctls can be handled by the calling layer(s).
Clean up the recently added code:
- include the appropriate header to declare an implicitly declared function.
- declare timeout functions correctly and remove numerous bogus casts that
hid (but didn't fix) their incorrectness.
after ttioctl too, because it can change t_line.
Remove (TS_CNTTB | TS_LNCH) test, it is always inherits from
old tty mode and can't be reach in currently setted mode.
o the includes are now properly done by <sys/foo.h> instead of "foo.h"
o a bunch of undeclared functions has been resolved
o pcvt finally supports devconfig
When attempting to abort a command, don't assume that just because the
sequecer happens to have SCBPTR pointing at the scb we want that it is
an active command.
old value.
Remove unnecessary check for active messages in setup SCB. This same test
would also jump to p_mesgin_done which would "ACK" an extra time possibly
confusing the target.
Tell the kernel driver whenever we send an ABORT_TAG message.
In rare cases, when the filter specified accesses an multi-byte value that
is split across mbuf's, the value loaded is incorrect. And if you are very
unlucky (like me) it will index off the end of the mbuf and into an
unallocated page and panic the system.
If you look at the code you will discover the the index *k* is added to
the pointer *cp* and the used AGAIN as a subscript.
1. Nuke out the aculib files that crept in somehow by mistake.
2. Fix the ${.CURDIR} path so that this stuff actually compiles.
It actually compiled for me before the commit, but I must have had
something short-cutting the bug.
to poll succesfully even if we are sharing the interrupt.
Register the interrupt handler before the attach.
This commit makes the 294x PCI shared interrupt compliant. This has
been tested with an aic7870 motherboard controller and a 294x in the
same machine shareing an irq.
- Report valid residual byte counts. We actually pause the sequencer
when the residual is non-zero. I thought about using DMA to do this,
bus sequencer program space is tight.
- Fix embarassing off by one error in the computation of a 2's
compliment variable. This was most likely the cause of the
many problems reported with the tagged queuing code.
- Handle "MAX_SYNC" as a special case (ie we are the ones starting
the sync negotiation sequence). This was done so that the target
scratch area can be initialed to 0 offset (asyncronous transfers)
safely. The initialization to 0 (was 15) is necessary since in
some cases a Wide negotiation could run into problems if SCSIRATE
was set wrong and we went into data(in/out).
- Trim the DMA routines a little by using some procedures. Net
effect is more functionality with 3 less instructions after this
update.
- Toggle the WIDEODD bit of the DFCNTRL whenever this is not the
last SG block. It has no effect in the 8bit bus configuration,
but in the Wide configuration ensures that the overlap byte is
held in the SCSI block if the transfer is odd so it will end
up in the next SG (the correct behavior).
- catch the interrupt type (EDGE/LEVEL) before chip reset instead
of guessing the right type.
- Add pause variable to the ahc struct to better handle the different
interrupt types and pausing the sequencer.
- CLRINTSTAT -> CLRSCSIINT: This is a documented bit in the CLRINT
register in newer Adaptec documentation, so use their name for it.
- Report valid residual byte counts.
- Don't mess with the target scratch areas > id 8 on single, narrow,
channel devices. The BIOS does a checksum of this area and can
flip out if we zero it out.
- Initialize the sequencer FLAGS scratch ram variable in the single
channel devices to 0. This was the cause of the annoying warning
where we would get a cmdcmplt the first time we did any type of
transfer negotiation with no valid scb. It also fixes the problem
that looked like the INTSTAT register wasn't clearing fast enough.
This only showed up on 294x cards, not motherboard aic7870s.
- Add the AHC_AIC7870 type and use it as the superset of aic7870
based controllers.
- clear the sync offset section of the targ scratch area so that
we default to asyncronous transfers. This was only a problem
for wide controllers because there was a scenario where the
offset wouldn't get updated before a data(out/in) phase would
occur. This required some change in the sequencer code since we
were depending on this field to hold the rate to negotiate.
- allow sync and wide negotiated commands to be tagged (the sequencer
now handles this properly).
