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.
We're about 75% there. SCSI and HP-IB are not yet supported in a new
config kernel; some autoconfiguration hackery has to be done there, yet.
These changes are enough to network boot a diskless kernel.
New config glue is enabled with the "NEWCONFIG" kernel option. If that
option is not present, an old config kernel will be built. Any kernel
configured with config(8) will automatically pick up the NEWCONFIG
option from std.hp300.
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.
XXX Maybe these diagnostics should be switchable by sysctl or
XXX options DIAGNOSTIC.
indirect bus code framework) from Jason Thorpe. This allows us to dump
bus_scan() and bus_print(), and move bus_peek() and bus_mapin() to the
NuBus code (since they'll eventually go away, anyway).
Because there is no way yet to tell init(1) to execute commands before
single user-mode is entered, the inittodr() function is still partly
functional. It retrieves the value of the RTC and sets the time as if
the RTC was running at UTC. The resettodr() function is a No-Op. The
RTC can only be changed by a write to /dev/rtc.
The TIMEZONE and DST options are no longer needed and removed from the
config files.
using __weak_alias in libc, __indr_reference should probably be defined
to do nothing (but defined, so that duplicate functions/variables aren't
compiled). However, when not using __weak_alias, __indr_reference causes
them to be omitted completely, which is a lose. So, until weak aliases
are going to be used, don't define __weak_alias or __indr_reference.
kit, then hacked on by Matt Thomas <matt@3am-software.com>, then by me (to
make it work with new versions of the toolchain, etc.). This runs, but it's
in serious need of cleaning and/or a fair bit of reworking. See the README
file for more information, and a list of things to do.
