#define clockframe somethingelse
to:
struct clockframe {
struct somethingelse cf_se;
};
and change access macros accordingly.
That means that, at least for that very issue, things will not go
ka-boomy if you don't have the actual definition of struct clockframe
before including systm.h.
When powersave mode is enabled, the TSC stops counting while the CPU is halted
in idle() waiting for an interrupt. This means we can't use the TSC for
interval time in microtime(9), and thus it is disabled here.
It still makes a perfectly good cycle counter for program profiling, so long
as you remember you're counting cycles, and not time. Further, if you don't
mind not using powersave mode, the TSC works just fine, so this should really
be optional. XXX
microtime_func = cc_microtime;
to a point after the CPU-specific setup routine is called because some of them
"turn off" the TSC because it's broken on those platforms, or not suitable
for use as an interval timer.
One such platform is the Cyrix/NSC Geode processor; when powersave mode is
enabled, the "hlt" instruction stops the TSC too. It continues to be perfectly
reasonable for program profiling as a cycle counter in this mode, but it is
unsuitable for interval time keeping (time doesn't stop just because you're
asleep or napping), and, for now, we don't have a separate flag to make this
distinction - we just test for the presence of TSC to enable cc_microtime().
1. remove MFS, not useful during installation.
2. remove extra ethernet drivers, some of them cannot be used without firmware.
3. remove pty multiplexor
4. remove ddb history
5. remove a.out support
6. trim down maxusers to 2
7. remove the beep device driver
8. remove nfsv3 support
One more commit to /usr/bin/ftp and everything will build again...
clock core, unlike its predecessors the cs5510 and cs5520.
This reverses the setting from i386/1386/identcpu.c where it argueably should
not have been set in the first place, as argued in PR kern/25261
XXX One other thing: the i8254 latch compensation code is only found in
i386/isa/clock.c and NOT in i386/i386/microtime.S where it should also be.
Stop including dev/pci/files.ath in arch/i386/conf/files.i386,
since we get the same definitions by including dev/pci/files.pci,
now. Remove dev/pci/files.ath.
Add arch/macppc/conf/Makefile.macppc with directives for linking
the Atheros HAL for PowerPC.
In athhal-powerpc-be-eabi.opt_ah.h, #define AH_REGOPS_FUNC 1, since
otherwise the linker complains that the PowerPC HAL cannot link
with register-read/write subroutines.
Add ath(4) to the GENERIC macppc kernel configuration; comment it
out.
