The trick question there is, the bootonce property is supposed to have generic boot descriptor, it does not have to be just zfs dataset name.... of course, if you have pools, then most likely you only do use zfs datasets.

hm, do we actually need this preprocessor #if statement?

Yeah. In the past I would have argued that we should work on support it (back when Intel had viable contemporary 32-bit hw and a 32-bit Tianocore to go with it) but at this point i386's future overall is not clear and we're not going to put effort into this.

so how was all this working before?
or is SEGDESC_t not all that important?

I think doing a functional function trace is mandatory before this commit, seeing what code is calling into what code, and what locks are in use.

If you need help ask, @zlei .

What @gbe reports clearly shows we can do better than just pushing changes and waiting for others to fix them.

--HPS

Nobody here said anything about "waiting for others to fix them". I hope that you understand that we cannot test every configuration possible.
And, sure, since now we have a report that it doesn't work on hyper-v nothing will be commited before the problem is understood and fixed.

nr_seg is int, but it can not get to negative, can it?

Maybe it should be moved to common?

Getting rid of default 9600 baud serial console is a good thing, we'll need to make sure this is widely documented in release notes etc.

Nice, thanks!:)

thanks!

small nits still, but good otherwise, I assume, this code does work as expected now?

Seems reasonable.

LGTM, thanks!

Some general comments...

The style of indented #if isn't what we do in FreeBSD. Code should be indented as if the #if isn't present, and the # directives should be in column 1.
We don't add extra spaces around the ('s, as I've highlighted
We don't do if (foo) bar; on one line.
logical operators are at the end of the line, not the start of the continuation.

It's an interesting notion... You'll likely want to do something similar to the EFI boot loader as well.

Thanks!

review feedback.

BSS would not had saved us as we do have code, data, bss, stack in low memory.

I like it too.
