Some of the stuff (e.g., rarpd, bootpd, dhcpd etc., libsa) still will
only support Ethernet. Tcpdump itself should be ok, but libpcap needs
lot of work.
For the detailed change history, look at the commit log entries for
the is-newarp branch.
determine whether there was an error (if so, we unmap the slot space
for this device). Use this functionality to tell the attach function
that we couldn't clear the card's buffer.
Also in aesetup(), eliminate the bogus repetition of the error message
we print when the buffer clear actually fails. Noticed by Hauke Fath.
and allow the attach function to override the default watchdog. Also,
do some minor cosmetic surgery (rename bus space tags/handles and some
KNFing I missed the first time around).
- extdms_done is modified by things outside of our direct control;
it needs to be declared `volatile'
- CountADBs() fails when we call it the second time. We can work
around this by telling extdms_init() how many ADB devices we have,
only calling CountADBs() once.
indirect bus code framework) from Jason Thorpe. This allows us to dump
bus_scan() and bus_print(), and move bus_peek() and bus_mapin() to the
NuBus code (since they'll eventually go away, anyway).
second argument. The NuBus autoconfig code had to be reorganized as a
result of this, and looks much more like a directly-attached bus now.
These changes eliminate __BROKEN_INDIRECT_CONFIG.
to initialize conspa was invalid on non-040 machines, since we don't
know which MMU we're using on those, yet. On the other hand, by the time
we get to check_video() on the 040 machines, the MMU has been disabled.
Compromise: get the video PA in setmachdep() on the 040, and in
check_video() on the others. (This is not optimal. *sigh*)
- Add reset attribute sequences for bold, underline, and reverse
- Add insert/delete line sequences
- Recognize but ignore G0/G1 character set sequences
Performance:
- Speed up clear_line() when clearing the entire line
Also, some stylistic changes for checking/setting scroll region bounds
and in putc_getpars().
These changes make the ITE work properly with the 1.2 termcap file.
have an Apple Sound Chip. Make sure that we have configured the device
before allowing accesses to ASC memory. Among other things, this
prevents the 660AV and 840AV from getting a kernel bus error when trying
to beep on the console.
instead of 0x400.
- Restructure interrupt handling for more performance--continue to
read/write data as long as the device keeps us in a data xfer phase.
There is still a lot of room for speed improvement here. Perhaps it
lies is speeding up the interrupt path in general?
some guesses for the machines that have two of these buggers (I don't have
such a machine). This driver is a copy of the sparc/alpha esp with a
minimum of changes--after we get it performing a bit more respectably,
we should see about re-normalizing the sources.
immediately reasserted before we get a chance to process the interrupt,
we can inadvertantly get stuck with zs_tx_stopped set. Move the delta
detection to the hard zs interrupt handler; the softint handler
will notice that something has happened with CTS and restart the
transmitter if it's asserted.
force a drop to the system debugger. WARNING: this used to be the
default behavior! Modify custom kernel configs accordingly.
- Check for ZS_HWFLAG_CONABRT in zs_abort(), and don't abort if it's
not set.
multi-channel driver), or to SCSI_CHANNEL_ONLY_ONE if a
single-channel driver.
(2) use scsiprint() rather than a locally-defined autoconfig print
function, and kill any locally-defined print function.
a char *, because that's what was really intended, and because
if the print function modifies the string, various things could become
unhappy (so the string should _not_ be modified).
one pending before we clear the interrupt flag. This avoids a condition
where the line appears to go catatonic (which is particularly easily
triggered by pppd). From Bill Studenmund <wrstuden@loki.stanford.edu>.
XXX - we should probably log this if it gets excessive.
occupy a slot. This is necessary so that GRFIOCMAP can find the correct
physical address of the framebuffer. Fixes P550, some LC models, and
perhaps the PB520.
- When finished writing, if the SCSI bus has BSY asserted, write another
byte to the SBC to ensure we get an interrupt.
- Unflag SCSI interrupts on the VIA whenever we clear the interrupts
on the SBC itself.
independent z8530 driver. When that driver is updated, the local copy
of those files may be removed. From Bill Studenmund.
Compiler warnings fixed by me.
visible screen memory. This results in a considerable performance win
at all depths.
- Correct clear_screen() behavior when clearing to the top and bottom of
screen; start at current cursor position, not current cursor row.
- Add local prototypes, and other KNF.
device and a printable "external name" (name + unit number), thus eliminating
if_name and if_unit. Updated interface to (*if_watchdog)() and (*if_start)()
to take a struct ifnet *, rather than a unit number.
Also change the device probing scheme to use something a bit more rational.
A current side-effect is that nubus cards are double-mapped. I expect
to fix that shortly.
Also change splclock() to block everything but serial hardware interrupts.
a condition that occurs with some slow SCSI devices when they disconnect
(e.g. the AppleCD 600), generating spurious selection interrupts.
- Reorganize the debugging code slightly.
- Disable interrupt-driven PDMA when writing (use polled PDMA instead).
- Be more careful about when to flag a transfer as completed.
The result of these changes is that interrupt-driven PDMA works well
enough to bring the system up.
- split softc size and match/attach out from cfdriver into
a new struct cfattach.
- new "attach" directive for files.*. May specify the name of
the cfattach structure, so that devices may be easily attached
to parents with different autoconfiguration semantics.
- Setting the "monitor BSY" flag for polled PDMA is non-optimal. The
polled requests generate an interrupt that isn't serviced until the
command has been cleared from the queue.
the MI 5380 driver. It has been verified to work on the IIx, IIsi,
and IIci only, but should work with any Macintosh 5380-based SCSI
controller.
- This driver is _not_ intended to be a general purpose replacement
for the `ncrscsi' driver. It is an alternative for those having
problems with that driver.
- Disconnect/reselect doesn't (yet) work, so don't expect SCSI tape
or magneto-optical disk drives to function properly.
reject them for simple commands. Leo W. reports that this does
not work for some systems. It's better than what we have now,
though. From Paul Goyette <paul@pgoyette.bdt.com>.
