* Support for bpf added.
* Don't duplicate code, use ether_ifattach instead.
* Recode plipreceive and pliptransmit in assembler.
This improves performance from 40 kbyte/s to 50 kbyte/s
between a 30mhz pc532 and a 25mhz i386.
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).
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.
- 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.
- New metrics handling. Metrics are now kept in the new
`struct disk'. Busy time is now stored as a timeval, and
transfer count in bytes.
- Storage for disklabels is now dynamically allocated, so that
the size of the disk structure is not machine-dependent.
- Several new functions for attaching and detaching disks, and
handling metrics calculation.
Old-style instrumentation is still supported in drivers that did it before.
However, old-style instrumentation is being deprecated, and will go away
once the userland utilities are updated for the new framework.
For usage and architectural details, see the forthcoming disk(9) manual
page.
* 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
