New generic disk framework. Highlights:
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.

work by rminnich@Sarnoff.COM. still needs RFNOWAIT support.

Add support for the SMC8416 (EtherEZ) ISA ethernet card.
The 8416 has an 8K shared mem (the old driver assumed 16K
and failed at attach time).

|
Also set sonic flag for MACH_CLASSQ.

Update a kludge from 4.4bsd/pmax: DECstation PROMs force the clock to
be in 1972 or 1973. If the clock is set to the actual time, the PROM
appears to reset the chip date to 1972 at each reboot.
Change the "year offset" from 22 years to 24 years (good till 1997)
until this code is replaced with something that uses the chip as a
seconds-since-beginning-of-year clock (encoded as a date, relative to
1972-01-01 00:00:00).

Part of the tostools reorganization. All directories now contain a Makefile
and the user interface to the various tools has been standarized.

Common library for all tostools. (Waldi Ravens and myself)

Atari partion table checker. Checks the validity of AHDI and/or
NetBSD/Atari partition tables. (Waldi Ravens)

splimp can drop, too.

Add '/emul/ultrix' pathname processing to Ultrix emulation, and move
Ultrix syscalls that require that processing out of ultrix_misc.c
to ultrix_pathname.c.

Device driver for TS11/TSV05 tape devices.

Deal with GCC's dead code elimination being suboptimal.
Modify splraise() to allow better optimization.
Make cpl, ipending, and astpending volatile.
Make sure interrupts are disabled before jumping to a resume point,
to prevent races.
Make FPU faults use INTRFASTEXIT, and remove INTREXIT.
Build the frame for recursive interrupts manually, and make sure to
disable interrupts to avoid races.

sure the store buffers on the chip are completely flushed to ensure
proper handler completion.

Move the obviously machine-dependent HP-UX compat code to hpux_machdep.{c,h}.
A fair bit of this, the m68k core dump and exec goo, can probably be
made into a generic m68k hpux module, eventually.

Add an nvram-driver. This driver makes it possible to read/write the
configuration info stored in the nvram on the mc146818

timing patch. I switched them back.

Implement vhangup(); more or less as suggested in PR#1560 (matthew green).
I'm vrele'ing s_ttyvp here too, so sys_exit() won't have to go over it again.
|
|
|
|
note: the use of unions and structures in here is bad; the use of
bitfields is even worse. the interface defined here desperately
needs a cleanup.
