I loaded a LiquidAI 4-bit, a tiny one, into my GPU on Linux. Now I get plausible answers and it works good.

hrm.. did i miss it, or does the mlxcx driver not expose any kstats beyond the standard mac ones?

i wanted to make sure it's not dropping things because of lack of descriptors, dma buffers, etc.

(which don't have standard kstats, but many drivers expose stuff like that as driver specific kstats, but i didnt' see any w/ mlxcx looking briefly)

anyone heading to the openzfs summit later this week?

It's been a bit since I've dug into mlxcx, but nope, no kstats from it per se.

kebe(io/mlxcx)[0]% git grep kstat

kebe(io/mlxcx)[1]%

With cxgbe getting a lot of love, fewer immediate reasons to dive into mlxcx. I was lucky to get a spec sheet from a customer who buys enough nvidia gear to get them to cough one up.

have any of you used SF1_SUNW_ADDR32?

so disappointing -- it appears mellanox used to make it pretty easily available...

thankfully i was scratching my head because it turned out to be a firewall problem...

but it kinda resembled a bit like a ring might have been stuck somehow

further from asking if any of you have used SF1_SUNW_ADDR32, do any of you have institutional knowledge about what the hell it was for?

(separate from what it does, which I know, and what it is probably meant to do, which I think I know)

also if you just want to play along at home, be aware it looks like Rod screwed his commit messages when he did this, so if you read the _other_ commit, you'll just be very puzzled

richlowe: based on a comment in machdep_sparc.h it would appear to be a variant 64-bit ABI which was limited to a 32-bit address space. Big registers, small pointers

yeah, that's what it just about does. I was wondering if we knew who for

6755162 is the good one

where raf implemented the rest of it

not clear where it just refers to a compiler RFE if they had something in mind, or just if they thought it was a good idea maybe

richlowe: benchmarketing. For what it's worth linux copied this idea with the "x32" ABI; looks good on benchmarks but nobody uses it in practice and they were talking about ripping it out.
