Given that support is known to be partial, would it make sense to keep it disabled by default for 2.4?
What is partial about it?
Ow, looks like I didn't send out the response to the patch itself. Will do.
In fact, considering that q35 behavior is still experimental it makes no sense to even make it conditional.
I agree to this, though an option to disable seems useful for debugging, so I'm glad that Paulo implemented it. It's probably not strictly required to disable for old machine types, but why not.
We discussed this on IRC and I was hoping to hear you reply "sorry, I was wrong". Instead, I get this.
Michael, I'm seriously getting annoyed by this behavior. Stop scaring away contributors.

Doing my best here, but I do think we need to be careful about merging things at this stage to avoid delaying the release.
This way in 2.5 we won't need to add more flags to stay bug
compatible.
Hi Michael,
I have seen no use other than watchdog functionality of TCO. The reason I wrote it was because I was working on an internal project that needed TCO to generate SMI so that my registered SW SMI handler in firmware would get executed. If, at that time, I had it supported on QEMU that would certainly have saved a lot of time instead testing it on bare hardware :-)
Given that, I think it's OK for me to enable it by default on pc-q35-2.4 and later.
Thanks,
Paulo
