until a proper fix is available:
Perpetuate the 4.4bsd design even further. Change keyboard-driver
open routines to check for an active raster console. If active, set the
keyboard struct tty's t_winsize from the rcons t_winsize on first open.
See pr 4438 for remaining problems and discussion of a complete fix.
* add includes for sys/dev/scsipi headers.
* cut-and-paste mode_sense and disk-geometry sense code from sd.c,
with name changes sd -> rz.
* Write `rz_command()' to send SCSI sense commands based on
existing rz size-sensing code.
* get geometry info with page 4 and page 5 mode sense.
* use resulting geom info for default label, fake label, and when
using ultrix labels. (ultrix labels have no geometry info).
Fixes incrrect-label bugs with using sysinst to install onto

to remove. The address of the pointer rather than the address of what
is pointed to was use to track the previous handler resulting in problems
when releasing a chained irq. (from John Ballance)
Added check for zero terminator after removing spaces in
get_bootconf_option(). This fixes a problem of matching NULL terminators
if there are trailing spaces in the boot args.
configured into the kernel, or when the platform is not supported.
Use the defopt'ed options, rather than NDEC_... and remove the needs-flag
hack that's existed for a while.
- clean up debug code
- Don't check ATAPI signature when probing ATA drives, ATAPI devices were
detected before
- Reset controller after disks probes. The probe, with some combinations of
ATA/ATAPI device keep it in a mostly working, but strange state (with busy
led on)
- The WDCF_IRQ_WAIT flag is now cleared by wdc_ata_intr and wdc_atapi_intr
when appropriate (helps recover from failure conditions)
- In wdcunwedge, send ATAPI_SOFT_RESET to non-ata drives
(helps recover from failure conditions)
- in wdctimeout be a bit more verbose when we missed an interrupt
- Always Increment xfer->c_skip where it should be
- Set the ITSDONE flag when a polled command completed.
for 12-bit addresses. This causes PCMCIA cards mapped at 0x400 and higher
to not function properly. However, the range 0x300-0x3ff causes some
laptops (e.g. the NEC Versa 6030X) to hang if cards are mapped there.
So, after some experimentation, we compromise. If the probe discovers
a 12-bit address bus, don't trust it. Instead, use the range 0x330-0x3ff.
This has been shown to work on the laptops that the 0x300-0x3ff range is
known to fail on.
supports generic SMC91cxx-based ISA cards and the built-in SMC
Ethernet found in some laptop docking stations.
Thanks much to Andrew Gillham <gillhaa@ghost.whirlpool.com> for
making this work!
but is a marked improvement. This takes advantage of a pseudo-DMA hardware
hack of Apple's that exposes a 16-bit register that the Apple-designed
memory controller acts like a DMA controller and handshakes into or out
of the FIFO. Wierd.
Unfortunately, there does not seem to be a good way to determine what
variety of comm-slot card is present in a machine. There is still an
interrupt issue preventing these cards from working--hopefully that will
be ironed out shortly.
normal rei course. If the handler returns non-zero, just rte.
This should allow better MACE response-time and still keep serial
interrupt overhead to a minimum on older, slower machines.
their double-underscore counterparts (cpp evil).
- define __RENAME() to do what lint expects, so that
renamed functions are handled properly.
From Chris Demetriou <cgd@pa.dec.com>.
- fix _C_LABEL so that it actually works.
- make __RENAME use _C_LABEL.
- fix __RENAME so that it expects an unquoted argument.
- fix __indr_reference and __warn_references so that they
supply their own final semicolon.
- define __warn_references to nothing if not GNU C (required
by the way it's used).
The __warn_references semicolon change has to be made
so that __warn_references can be defined into nothing.
(A ; all by itself isn't a great idea.) The __indr_reference
change was made for consistency.
and swapctl(). For the former three, they use an 'int' in their user-land
prototype which was a 'u_int' in the kernel, which screwed up automatic
generation/checking of lint syscall stubs. For the latter, the user-land
prototype uses a "const char *", but the syscall just used "char *".

more robust in resource shortage situations, basically identical to
code I added to the "ahc" driver some time ago.
Thanks to Brad Spencer for the testing help.
internal ethernet on the Quadra/Centris 660av/840av.
Add initial support for the PSC (DMA controller) to support the above
(DMA SCSI remains unsupported). This involved also changing the way
that several interrupts are handled.
Above from David Huang <khym@bga.com>
Since the interrupts changed somewhat, we must also make the ipls
dynamic, defaulting to their prior levels and adjusted for the AVs.
I modelled this on the hp300.
touched any user-space address recently. This is efficient
for things that stay in the kernel for a while, waking up
to handle some I/O then going back to sleep (i.e. nfsd).
If and when such a process returns to user-mode, it will
fault and be given a real context at that time.
This also makes context switch faster, because all we need
to do there for the MMU is slam the context register.
since today, they will have the same size as the on-the-wire-packet on each
architecture.
Problem was reported by George Harvey for the m68k architecture.
