- Fix data frames transmission via POWER_STATUS register setup -
it seems to be set by MACID_CONFIG firmware command, which was broken*
in r290439 and later disabled in r307529.
We can re-enable it later if / when firmware rate adaptation will be
ready; however, this step will be required anyway - for firmware-less
builds.
- Force RTS / CTS protection frame rate to CCK1 (this rate works fine
without any additional setup; no better workaround is known yet).
The problem was not observed on the channel 1 or with CCK1 rate enforced
('ifconfig wlan0 ucastrate 1' for 11 b/g; not possible for 11n networks
due to ifconfig(8) bug).
* I'm not sure if it works before r290439 because - AFAIR - I never seen

Since in most configurations CTL serves as network service, we found
that this change improves local system interactivity under heavy load.
Priority of main threads is set slightly higher then worker taskqueues
to make them quickly sort incoming requests not creating bottlenecks,
while plenty of worker taskqueues should be less sensitive to latency.

FDT data. The sector size must be a multiple of the device's page size.
If not configured, use the historical default of the device page size.
Setting the disk sector size to 512 or 4096 allows a variety of standard
filesystems to be used on the device. Of course you wouldn't want to be
writing frequently to a SPI flash chip like it was a disk drive, but for
data that gets written once (or rarely) and read often, using a standard
filesystem is a nice convenient thing.

The latter is the only functional change, it makes the number match the

This is especially important for writes. SPI is inherently a bidirectional
bus; you receive data (even if it's garbage) while writing. We should not
receive that data into the same buffer we're writing to the device.
When reading it doesn't matter what we send to the device, but using the
dummy buffer for that as well is pleasingly symmetrical.
ExitBootServices terminates all boot services including console access.
Attempting to call printf afterwards can result in a crash, depending on the
implementation.
Move any printf statements to before we call bi_load, and remove any that
depend on calling bi_load first.

On very large powerpc64 systems (2x22x4 power9) it's very easy to run out of
available IRQs and crash the system at boot. Scale the count by mp_ncpus,
similar to x86, so this doesn't happen. Further work can be done in the future
to scale the I/O IRQs as well, but that's left for the future.

When a vCPU is HLTed, interrupts with a priority below the processor
priority (PPR) should not resume the vCPU while interrupts at or above
the PPR should. With posted interrupts, bhyve maintains a bitmap of
pending interrupts in PIR descriptor along with a single 'pending'
bit. This bit is checked by a CPU running in guest mode at various
places to determine if it should be checked. In addition, another CPU
can force a CPU in guest mode to check for pending interrupts by
sending an IPI to a special IDT vector reserved for this purpose.
bhyve had a bug in that it would only notify a guest vCPU of an
interrupt (e.g. by sending the special IPI or by resuming it if it was
idle due to HLT) if an interrupt arrived that was higher priority than
PPR and no interrupts were currently pending. This assumed that if
the 'pending' bit was set, any needed notification was already in
progress. However, if the first interrupt sent to a HLTed vCPU was
lower priority than PPR and the second was higher than PPR, the first
interrupt would set 'pending' but not notify the vCPU, and the second
interrupt would not notify the vCPU because 'pending' was already set.
To fix this, track the priority of pending interrupts in a separate
per-vCPU bitmask and notify a vCPU anytime an interrupt arrives that
is above PPR and higher than any previously-received interrupt.
This was found and debugged in the bhyve port to SmartOS maintained by
Joyent. Relevant SmartOS bugs with more background:

In all of the architectures we have today, we always use PAGE_SIZE.
While in theory one could define different things, none of the
current architectures do, even the ones that have transitioned from
32-bit to 64-bit like i386 and arm. Some ancient mips binaries on
other systems used 8k instead of 4k, but we don't support running
those and likely never will due to their age and obscurity.
