For some reason it wouldn't get positioned right when mapped in through the
blitter memory mapped location, so switched to the register mapping, which
works.
XXX colormap handling for the cursor is still broken.
configuration. This way, the delay loop is calibrated before graphics and
serial hardware is touched.
This change should smooth pr 2890 by Thorsten Frueauf (also privately
reported by Laurent Badoukh). While the real problem with those is the
paranoically high delay() calls in the grf_cl initialization, it was made
even more visible by the miscalibrated (to the save side) new style delay
loop.
even if you "really didn't change anything dangerous" :-)
- While we're here, save a few bytes and clock cycles during kernel startup:
cinva ic clears the branch cache on the 68060, no need to do it explicitly.
for branch prediction errors (could be used to detect strange binaries),
integer instruction, FP instruction, FP data type and FP effective address
emulations. The latter can be used to diagnose binaries which should be
recompiled with -m68060.

making me think that the Blizzard-IV and the Blizzard-2060 scsi
options have nearly identical DMA engines (just with a different
address offset). Alas, this isn't true.
Herewith I replace the "bznsc" (all-new-Blizzard-models) driver with the
"bztzsc" (Blizzard Two Zero).
on indirect-config busses a (permanent) softc that they could share
between 'match' and 'attach' routines:
Define __BROKEN_INDIRECT_CONFIG so that old autoconfiguration
interfaces are used, until drivers are converted to use the new
interfaces (actually, converted back to use the _older_ interfaces)
which prohibit indirect configuration devices from receiving a softc
in their match routine that they can share with their attach routine.
Lets users over-ride with makeoptions COPTS="..." in kernel config files.
Leave `mandatory' flags (like -msoft-float which on m68k enforces no
FP in kernel) in CFLAGS.
drisavar.h pretends to provide a few bus.h macros, hardwired to
that chip.
This should eventually be replaced by attachment code for the normal
com.c driver, once that one is split up into chip core driver and
attachment code, and once we have busxxx macros in NetBSD/Amiga.
along with toolchain enhancements.
aout2bb transforms a.out files with reloc information into bootblock format
files with a compressed relocation info.
bbstart.s relocates the bootblock using this compressed info, before jumping
to C code.
txlt changes some more of the absolute references to pc-relative ones (we know
we have a single code + data address space).
If you ever try to change this: don't even dare to change the compiler options;
they were found in weeks of trial and error as the ones producing the smallest
(not necessarily fastests) code.
installboot is just a script around dd, for now.
Some ideas by Michael Hitch, Leo Weppelman and Jason Thorpe; bugs added
by myself.

after returning from hardclock(), rather than before. For some reason,
this fixes the 0xffffffff i used to see in the tv_secs of the used cpu
time of some processes.
XXX I don't fully understand the issue.
Earlier, we re-complained about excessive token losses about once a minute.
However, on small ARCnet networks, the token will also be lost if only one
station (us) is active (ifconfig'd down interfaces don't take place in the
token exchange), and our syslog would be filled with repeated messages about
this condition.
Our new code only complains once, starts a timeout() each time a token
regeneration is reported by the chip, and generates a log message about
the regenerated token if it was stable for 15 seconds.
buffer out of the hardware (it is invalid!).
This fixes hangups due to spurious rx interupts.
XXX Maybe I should completely reset the hardware in this case?
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.
Still untested on -1260/-1230, and hangs when enforcing SFAS_NO_DMA on 2060;
but works with DMA on the latter.
Still untested in a NetBSD-12A environment. (Sorry, don't have the hardware
myself.)
Thanks to Laurent Baroukh for being the guinea pig, and to Jerome Lovy
for forwarding the hardware information Phase V gave him, and to Phase
V for providing it.
