Normally a UFS/FFS filesystem with a bad check hash can only be
mounted read only. With this commit the mount(8) -f (force) option
can be used to force a read-write mount of a UFS/FFS filesystem with
a bad check hash. Conveniently the filesystem will proceed to
update its on-disk superblock with a corrected check hash.
Sponsored by: Netflix
When doing an initial mount(8) with its -f (force) flag, the MNT_FORCE
flag is not passed through to the underlying filesystem mount routine.
MNT_FORCE is only passed through on later updates to an existing
mount. With this commit the MNT_FORCE flag is now passed through on the
initial mount.

There is no universal way to find the TSC frequency. Newer Intel CPUs
may report it via CPUID leaves 0x15 and 0x16. Sometimes it can be
obtained from the PLATFORM_INFO MSR as well, though we never use that.
On older platforms we derive the frequency using a DELAY(1000000) call,
which uses the 8254 PIT. On some newer platforms the 8254 is apparently
non-functional, leading to bogus calibration results. On such platforms
the TSC frequency must be available from CPUID. It is also possible to
disable calibration with a tunable, in which case we try to parse the
brand string if the TSC freq is not available from CPUID.
CPUID 0x15 provides an authoritative TSC frequency value, but even that
is not always available on new Intel platforms. CPUID 0x16 provides the
specified processor base frequency, which is not the same as the TSC
frequency. Empirically, it is close enough for early boot, but too far
off for timekeeping: on a Comet Lake NUC, CPUID 0x16 yields 1600MHz but
the TSC frequency is rougly 1608MHz, leading to frequent clock stepping
when NTP is in use.
Thus we have a situation where we cannot calibrate using the PIT and
cannot obtain a precise frequency from CPUID (or MSRs). This change
seeks to address that by using the CPUID 0x16 value during early boot
and refining the calibration later once ACPI-based timecounters are
available. TSC frequency detection is thus split into two phases:
Early phase:
- On Intel platforms, query CPUID 0x15 and 0x16 and use that value
initially if available.
- Otherwise, get an estimate using the PIT, reducing the delay loop to
100ms from 1s.
- Continue to register the TSC as the CPU ticks provider early, even
though the frequency may be off. Otherwise any code executed during
boot that uses cpu_ticks() (e.g., context switching) gets tripped up
when the ticks provider changes.
Later phase:
- In SI_SUB_CLOCKS, once the timehands are initialized, load the current
TSC and timecounter (sbinuptime()) values at the beginning and end of
a 1s interval and use the timecounter frequency (typically from
kvmclock, HPET or the ACPI PM timer) to estimate the TSC frequency.
- Update the TSC timecounter, global tsc_freq and CPU ticker with the
new frequency and finally register the TSC as a timecounter.

Modify the GPIO pins only on the Base-T cards and even there drive all
of them low instead of putting them in hi-z state. For the rest (this
is the common case), directly power off the PLLs of the high speed
serdes. This is the simplest method that does not involve or conflict
with the firmware but still works with all T4-T6 cards regardless of
what's plugged into the port.
This fixes a problem where the peer wouldn't always see a link down if
it is connected to the device using a -CR4 copper cable.

Avoid this copying by having smp_targeted_tlb_shootdown() make a local
copy of the active CPUs for the pmap, and drop the cpuset parameter,
simplifying callers. Also leverage the use of the non-destructive
CPU_FOREACH_ISSET to avoid unneeded copying within

When reading UFS/FFS superblocks that have check hashes, both the kernel
and libufs print an error message if the check hash is incorrect. This
commit adds the ability to request that the error message not be made.
It is intended for use by programs like fsck that wants to print its
own error message and by kernel subsystems like glabel that just wants
to check for possible filesystem types.
This capability will be used in followup commits.
