TSO

[rlippmann]

Hi,

So, just wondering if this might help things for box64. Probably not, because it's either already implemented, or not useful.

But apparently you can tell Apple silicon to use a TSO memory model. I have no idea what that means, but it seems like it makes x86 emulation faster.

Here's a suggested linux kernel patch to enable it.

But, in case this is actually useful, I thought I'd post this here....

Yes, I'm aware of that. I plan to add support for this at some point, but I'm not using M1 a lot, so it's low priority for now.

Box64 works fine without this mode already (with it's integrated TSO simulation), but I do expect this to make things a bit faster when some kind of TSO is needed on the M1 family CPUs.

So it's only for M1? Bummer.

it's for all Apple Silicon CPU to my knowledge.

Would it require this commit to be merged first?

[ptitSeb]

Not sure what commit you listed (404 for me), but to my knowledge, TSO mode is already integrated in asahi linux.

Sorry, this one
