<courmisch>
so BPI-F3 has Zicbop, but kernel has no hwprobe flag for it, does it?
zjason`` is now known as zjason
<conchuod>
courmisch: I don't think there's even detection of it yet, let alone hwprobe support.
<conchuod>
Both are trivial to do, but just requires someone caring - although if there's a board with it I guess someone probably will.
<courmisch>
conchuod: cpuinfo claims it's there. Whether it's doing anything, I haven't benched. It's a no-op otherwise
psydroid2 has joined #riscv
<conchuod>
courmisch: It does? Are you running some thead kernel?
<conchuod>
I know guo posted some patches for zicbop over new years, but hasn't shown up with a v2. His series didn't include hwprobe (and the thead kernel well predates that interface anyway).
<conchuod>
It does, a classic 4 commit kernel tree
<courmisch>
I mean, I don't know if it matches the SD card image
<conchuod>
I've seen some of this before actually, they've got some "interesting" use of a non-standard "base" SBI opcode in some shutdown/suspend/offline path I think.
<conchuod>
courmisch: Ye, from a quick check it looks like there's detection but nothing more. Don't see any of Guo's prefetch stuff in that.
<courmisch>
still looks like a very long way to an upstream kernel
<conchuod>
I dunno, arch code wise it doesn't look super far away - mostly backports other than their "AI" stuff.
<courmisch>
that's quite a long list of custom drivers
<courmisch>
and lets not get started on the GPU
<conchuod>
Oh ye, but there's a lot less controversy in peripheral drivers! Some of the vendor kernel's custom stuff in arch/ is far more likely to be a problem.
<conchuod>
But ye, still likely a long road if there's not some pretty motivated people upstreaming support.
<courmisch>
if the VF2 PCIe driver is anything to go by, cough cough
<conchuod>
Hey, you can blame me for that taking ages.
<conchuod>
Well, and the bugs in their hardware too I guess.
<conchuod>
But I got notifications for that series being picked up last week, so that might be at an end.
<courmisch>
well, not my problem, unless somebody wants to poach me from the clutches of my Chinese megacorp employer
<courmisch>
The vendor image seems way saner than K230's, so I won't be doing That Thing again
<conchuod>
The k230 took the usual T-Head SDK problems and made it worse
