compiles in GENERIC for i386. This is still a work-in-progress, but
this checkin covers most of the mechanical work (changing signalling
to be able to accomidate SA's process-wide signalling and re-adding
includes of sys/sa.h and savar.h). Subsequent changes will be much
more interesting.
Also, kern_sa.c has received partial cleanup. There's still more
to do, though.
at programatic use where the caller wants to be able to use PKCS#5.
Disable looping on invalid verifications unless both a passphrase method
is in use and the -p flag is not specified.
Update man page to document -p flag.
- Ditch the cross-CPU calibration stuff. It didn't work properly, and it's
near impossible to synchronize the CPUs in a running system, because bus
traffic will interfere with any calibration attempt, messing up the
timings.
- Only enable the TSC on CPUs where we are sure it does not drift. If we are
On a known good CPU, give the TSC high timecounter quality, making it the
default.
- When booting CPUs, detect TSC skew and account for it. Most Intel MP
systems have synchronized counters, but that need not be true if the
system has a complicated bus structure. As far as I know, AMD systems
do not have synchronized TSCs and so we need to handle skew.
- While an AP is waiting to be set running, try and make the TSC drift by
entering a reduced power state. If we detect drift, ensure that the TSC
does not get a high timecounter quality. This should not happen and is
only for safety.
- Make cpu_counter() stuff LKM safe.
It wasn't noticed till now as it wasn't overflowing onto anything
important (or was overwritten by the correct data). Recent changes
meant irqstr was placed just before footbridge_intrq and so it trashed
the interrupt linked list, and so caused an alignment fault.
Note that cats still doesn't boot even with the change, as it hangs when
starting userland, I suspect an interrupt issue.
Also fix build with DEBUG_IRIX defined.
Fixes PR port-sgimips/38367 and makes GENERIC build again.
Only build tested because something else is still wrong with compat_irix.
