too much damange. everything else here is the same in a 64bit vs. 32bit
world, so keep it all simple. the alpha was the only port to have any real
affect for this, and it only very recently begun to support some audio
devices so it doesn't really apply here. 1.3/alpha did not support audio..
properly! Work around this by determing current active media by taking
the highest-order common bit of our advertised capabilites and the link
partner's.
If the link partner doens't do autonegotiation, then parallel detection will
pick up the media type, which will never be full-duplex, so reading the PAR
is ok in this case.
Bug pointed out by Matthias Drochner, work-around inspired by reading
the dp83840 manual, section 3.9 (IEEE 802.3u auto-negotiation).
Replace it by a variable, which is initialized in amiga_init.c.
This will make the kernel actually work even if we have lots of Zorro-III
(or DraCo direct bus) i/o space.
the 3Com 3c905-TX and 3c905-T4. Fix handling of the MII on the
3c595-MII and 3c597-MII (can't talk to the PHYs on these cards; just
use "manual" for the external MII port).
Fixes kern/4782 (Chris Demetriou).
the hp300 port.
- Interrupts 3-6 use this immediately. Interrupt 7 is a special case,
and the VIA interrupts (1 and 2) will be addressed when that code is
rototilled.
- Modify the zs front end to register with the appropriate interrupt
controller: through the PSC on the AV Quadras, and direct to
interrupt 4 on the rest. Arrange to have the appropriate zsc_softc
supplied to us at interrupt time.
- Modify the direct ADB driver (and its PowerManager cousin) to call
intr_dispatch(), rather than zshard(). XXX This is a kludge, but at
least limits the brokenness to the ADB drivers, now.
As a side effect, this should fix PR 5590. Thanks to Bill Studenmund for
correctly determining the cause of the problem reported there.
