<rwmjones> davidlt: hey!
<rwmjones> I'm just back from holiday
<rwmjones> let me see ...
<davidlt[m]> I assumed that you are most likely PTO or similar, but you didn't change your nickname this time.
<rwmjones> yes nujive is currently in a loop of kernel stack traces
<rwmjones> let me go & kick it ...
<davidlt[m]> Juat reboot it and it should get a task :)
<rwmjones> yup :-)
<davidlt[m]> I might cook up a new Haskell build for it before hitting the bed too.
<davidlt[m]> djdelorie: how is your board? physically dead or just something with the software?
<djdelorie> dunno yet. I have other priorities this week
<davidlt[m]> That's fine. Just wanted to check :)
<rwmjones> sorry davidlt[m] I suck! I turned nufive off by accident
<rwmjones> both now rebooting ...
<davidlt[m]> rwmjones: well, thankfully it was a GCC 13 build with just ~4 hours on the clock :)
<davidlt[m]> Jakub is bumping GCC 13 something like every 3-4 days, which is hard to keep up.
<rwmjones> not so bad :-)
<davidlt[m]> Most of your boards just build GCC 13, which takes a bit more than 200 hours.
<rwmjones> hehe
<davidlt[m]> The sad part is what GCC used to take significantly less time, but any newer hardware will just bring us closer to the older build times, but probably not help with new record build times :)
<rwmjones> my office was like 21C through the whole holiday even though the outside temp was near freezing
<davidlt[m]> Sipeed is finally launching their boards with TH1520.
<rwmjones> I need to get the VF2 working as well
<davidlt[m]> I am surprised that it could be freezing in London :)
<davidlt[m]> Heck, you had spring in January :D
<rwmjones> it's been quite cold here recently, even today
<davidlt[m]> VF2 initial support is landing in 6.4, so it's close now.
<davidlt[m]> From cheap SBCs Sipeed TH1520 will replace VF2 as perf/dollar (i.e. value) board.
<davidlt[m]> I mean it's 2.0GHz and OoO cores, with 16GB of fastest memory we have seen on RISCV SBC. Also T-HEAD extensions, which are not yet hooked into glibc IFUNCs.
* rwmjones puts head in hands over T-HEAD extensions ...
<davidlt[m]> But huge negative -> lack of upstream support.
<davidlt[m]> T-HEAD extensions are part of GCC 13 and binutils 2.40 IIRC.
<davidlt[m]> So the toolchain in our Fedora 38 will support them (except vectors).
<davidlt[m]> What's missing is HW probe interface, which probably will land in 6.4 too.
<davidlt[m]> (or 6.5)
<davidlt[m]> Yeah, that's their public spec, and GNU and LLVM toolchains follow it.
<davidlt[m]> The only thing this doesn't have is vector.
<davidlt[m]> For some reason they decided not to make T-HEAD extension for that ❓️
<rwmjones> is this in any way related to anything from the Foundation?
<davidlt[m]> Yeah, some of these are kinda obsolete now from my point of view.
<davidlt[m]> Some have the same names as RVI official extensions now, just with THEAD prefix.
<davidlt[m]> I bet whatever comes after their C920 core IP will deprecated some of these.
<davidlt[m]> XTheadBa, XTheadBb, XTheadBs, XTheadCmo
<davidlt[m]> Probably also XTheadCondMov
<davidlt[m]> C920 is what they have in that 64-core SoC.
