- New variables: biosextmem, biosbasemem, nkpde
- Above can be set by using the options BIOSEXTMEM, BIOSBASEMEM,
and NKPDE respectively (EXTMEM_SIZE is now called BIOSEXTMEM).
When preset this way, they won't be filled in / calculated.
- Readable by sysctl using machdep.nkpde, machdep.biosbasemem
and machdep.biosextmem.
- nkpde is calculated as:
min(NKPDE_MAX, NKPDE_BASE + (biosextmem >> 10) * NKPDE_SCALE)
Where NKPDE_MAX is 31, NKPDE_BASE is 4, NKPDE_SCALE = 1.
* Add a slot in the softc, ep_pktlenshift, to indicate that
a board implements ``large packets'' (FDDI-sized frames) and
therefore implicitly shifts the argument to packet-length commands
by two bits to fit a 13-bit length in an 11-bit command argument field.
* Change the reset of station-mask filterto be independent of bus-type
(e.g.,. for 3c515)
* Replace the "2044" constant used to disable TX threshold interrupts
on 3c509-generation cards with a #define. Use 2047 instead,
since that works on the large-packet cards (Vortex, Demon, Boomerang)
and 2044 doesn't.
* Add code to epconfing to probe for large-packet support,
set the softc appropriately, and shift packet sizes in commands
by ep_pktlenshift to compensate for the implicit shift.
* Tweak the epconfig() code to avoid hanging on startup.
Set the Tx threshold to interrupt when there's space for
a maximal-sized ether frame, then do epinit() then epstop(),
instead of just the Tx and Rx reset. Required on at least a 3c595.
Tested on a 3c595, but not on 3c509-generation hardware.
support for shared libraries. Diffs from Manuel Bouyer, probably
derived from similar OpenBSD gcc diffs.
This change is in the source tree because it was used to build a NetBSD/pmax
shared-lib snapshot. The change isn't being integrated into the gcc2netbsd
script until the shared-lib diffs are finalized.
We test this condition AFTER the interupt condition, because it is only
disabled during autoconfiguration.
Without this patch, if autoconfiguration takes long enough, eventually a
timer interupt will call hardclock() and panic the machine.

Manual. This may not work, but it's the best i can do with the
documentation I have.
is set in the RPB's rpb_variation field. This fixes a bug where machines
(e.g. the 3000/900) would see that they could touch memory where a built-in
PMAGB-BA, assume that it was there, and panic later because the memory they
were accessing didn't look like PMAGB-BA registers (because it wasn't).
gcc thinks that the 'q' modifier describes a "long long", and so -Wformat
whines when printing with 'q' on the alpha, since int64_t-sized types are
done with variations on "long" rather than "long long".
Also allow compilation with -DSMALL to ommit support for
non-essential protocols (i.e. when built into a ramdisk).
Use a less hack-ish way to generate keywords.[ch] and just
check in the result (helps ../../distrib/utils/x_route).
