Reduce the diff, by sharing the same VT driver between the early attach and delayed attach. This required moving some config setting into the probe routine, but that should be fine.

I should probably caffeinate before making such trivial changes.

Change to nwhitehorn's preference. Either is fine with me.

This can be simplified to just "if (count < (int)sizeof(cell_t))"

Bump PORTREVISION on print/qpdf and games/qqwing. They're dependencies for
packages that need c++11, and themselves, on their own, don't really need c++11,
but their dependent ports won't link otherwise.

LGTM.
Please consider opening an issue at https://www.illumos.org/projects/illumos-gate/issues even though illumos does not support PowerPC.

Expand to all ZFS uses found.

The code looks fine to me. Can you include a test for it? You showed me the torture test, so that'd be good to include in tools/tools. With a test, I'll approve it.

Some of these need PORTREVISION bumps IIRC..

Drop mail/evolution. It failed the jenkins build for unrelated reasons.

Eliminate an extraneous parenthesis pair, add the mpc85xx check to create a
512MB boot partition.

Overall I like the optimization here. I think memmove()/memcpy() are used often for relatively large block copies, so I really like the savings it offers. Just a few comments to address.

Looks good

On POWER9, I think the lock is unnecessary (the ISA spec doesn't mention it).

Ping? With this and two other reviews, I can now boot FreeBSD on POWER9 to multiuser, so want to get these in soon.

No need to comment out the OPAL_PCI_MAP_PE_MMIO_WINDOW. It likely was already
mapped as such by Opal.

Hi. Could someone review my patch please?
Basically, this code loads and compares the chars by byte until their addresses are aligned.
After, we load and compare the chars by double word until a \0 or a difference in the chars is found.
Finally, we compute the differences between the chars.

Add a small delay, and a timeout, if a sensor needs extra time
(OPAL_ASYNC_COMPLETION/OPAL_BUSY).
