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 *".

this happened when i changed test2 from a void statement to actually
checking its return value.
the effect of this? a YP_MASTER_KEY value wasn't being added to the
generated databases, which was Not Good.
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.
was "C_block [][]", which isn't valid (or sensible!) C (only the last
dimension may be omitted). However, all of the dimensions are known
so they might as well be specified.
- Added -r rel flag to change the release tag on the tar files.
- Added Usage
- Fixed a menu bug (missing exit)
- Made target_expand available to all functions to produce correct
file names.
