* grok FIONBIO, FIOASYNC, and TIOC{G,S}PGRP
* add BIOC{G,S}RSIG; get/set the signal to be delivered
to the process or process group upon packet reception.
Defaults to SIGIO.
conditional on a gcc >= 2.7.0, but there's no good and easy way to do
that short of introducing a new global 'make' variable, which i think
is a bad idea.
* conf/DEFAULT: new file, default install kernel
* conf/INSTALL: +MSDOSFS, +NO_INLINE_SPLX, +RD_SIZE=2mb, +scn4/5
* conf/KLONDIKE: cosmetic changes
* conf/STEELHEAD: cosmetic changes
* conf/files.pc532: rd got a file of it's own
* dev/lpt.c: changes to support lower interrupt latency, packet input/output
is now done at spl0
* dev/ncr.c: changes to support the most recent atari version of the ncr5380
driver
* dev/ncr5380.c, dev/ncr5380reg.h: upgraded to most recent atari version,
memcpy -> bcopy.
* dev/rd.c: ramdisk driver
* dev/scn.c: by patching scndefaultrate, the kernel's default baud rate can
be changed with gdb
* include/psl.h: struct iv now protected by !LOCORE && _KERNEL
inlining of splx can be prevented with new kernel option NO_INLINE_SPLX
splx_di is like splx but leaves processor interrupts disabled
* pc532/autoconf.c: cosmetic changes
* pc532/conf.c: with rd entries
* pc532/intr.c: changes to support splx_di
* pc532/locore.s: ramdisk is no longer initialized
not splx, but rett is now used to reenable CPU interrupts when leaving the
interrupt service routine. This is necessary to prevent recursive interrupts.
* pc532/sys_machdep.c: memcpy -> bcopy
* pc532/mem.c: moved ramdisk to dev/rd.c
* stand/Makefile: boot is now loaded at 0x3eb800 instead of 0x363800
Use current form of libsa and libkern.
* stand/inflate.c: emit twiddle every 8k and not every 1k
* stand/rd.c: ramdisk starts at 0x288000
(should be DT_BLOCK). otherwise the bootxx boot block will fail if
you are on a system with a v2 openprom [because it will not do the
v2_seek in obp_strategy()]. fixes the problem recently noted on
the port-sparc list by matthew green <mrg@eterna.com.au>. i tested
fix on a ss2 with a v2 prom.
both off, haracters with their top bit clear were interpreted as a delay.
This (strange) behaviour is still available if SCC_PARITY_MEANS_DELAY
is defined.
