mace devices to their own mace/ directory. Alter conf/files.sgimips to
reflect this change in a sane manner (i.e., pull in dev/files.dev and
mace/files.mace when appropriate).
At the same time, allow crime_intr_establish() to fall through to
mace_intr_establish(). mace devices now call cpu_intr_establish().
While here, do some cosmetic changes:
* sort PCMCIA network interfaces section.
* ksyms is not a wscons related pseudo device, so move it to misc.
* line up scif at shb line, and move related options to be after it.
* move all device-specific bitbanging to the device drivers in question --
i.e., the ip32 init code doesn't access the CRIME registers directly but
instead trusts the CRIME driver to DTRT. machdep.c is cleaner thereby.
* introduce int.c, which handles the interrupt-controller goo formerly
in ip2x.c.
* unify the CPU interrupt handler, with CRIME, INT2, and the various timer
handlers hooked in via pointers in the platform struct.
* eliminate ip2x.c and ip32.c. After the interrupt handler cleanup, the
actual platform-dependent code was so minimal (rev identification, mask level
initialization) that it made sense to move it into machdep.c
* "#ifdef DEBUG printf("foo"); #endif" becomes aprint_debug.
Tested on my ip22 and ip32. Discussed with pooka@, rafal@.
Remove the vestigal sysbeep device and replace it with the same kind of
mechanism that pckbd(4) uses to find the bell, which is just as ugly, but
more standard. Adapt beep(4) to the new world (though I'm not sure it
deserves to live).
systems that don't have a dedicated feeper. It's up to MD code to enable
this by having the "audiobell" attribute and calling audiobell() at the
appropriate moment.
Code for making noise in the kernel from Richard Earnshaw. Simple synthesizer
design from the RISC OS Programmer's Reference manual.
Kill mksyntax.c - no longer possible to get the 'wrong sort of chars'.
/bin/sh now has no helper binaries.
syntax.c uses C99 initialisers, run time initialisation could be used
for systems where the compiler doesn't support them.
I've used some #defines to help make this possible - but writing the code
starts making it rather messy.
Use CHAR_MIN (from limits.h) to determine whether target char are signed
or unsigned - the syntax tables will not be indexed properly.
Rip out all the stuff from mksyntax.c that wrote syntax.h.
syntax.c can stiff be generated incorrectly...
Build mksyntax directly from mksyntax.c so that the -DTARGET_CHAR=xxx
is applied when it is build.
OTOH mksyntax is broken as it tries to determine properties of the
target system by running code on the build system.
It was already merged in the XFree86 4.x source anyway, and it doesn't
make senses to keep some programs in a separate set just because they
used to be built from a separate directory in XFree86 3.x.
