<davidlt[m]> Nothing interesting to report. Pretty much boring stuff. Packages are being built, nothing significant is happening.
<davidlt[m]> We are still a few 1000s of builds away before starting to see more red (i.e. failing builds) popping up.
<davidlt[m]> LLVM 16 is landing in F39 now, but haven't seen any builds for F38 yet.
<davidlt[m]> Well vectors are ratified IIRC.
<davidlt[m]> There is a bunch of vector stuff being done in GCC 13 (even in stage 4).
<davidlt[m]> But things like autovec will land after GCC 14 is open.
<davidlt[m]> Some things aren't ratified like vector intrinsics IIRC.
<davidlt[m]> That's annoying because there are already projects that depend on old stuff.
<davidlt[m]> There are headers to convert to a newer stuff (but newer stuff is not final too).
<davidlt[m]> Thus GCC 14 and LLVM/Clang 18 will be interesting. Hopefully all ratified and aligned in the toolchains.
<davidlt[m]> There also should be psABI updates later this year.
<davidlt[m]> A lot of bits before RVA23 arrives.
<davidlt[m]> This might be interesting board/SoC: https://news.itsfoss.com/asus-tinker-v-risc-v/
<davidlt[m]> It's ASUS IoT Tinker-V stuff.
<davidlt[m]> It comes with Renesas RZ/Five SoC, which incl. Andes X45MP.
<davidlt[m]> Andes has upstream support and there has been a lot of upstream activity around Renesas RZ/Five SoC.
<davidlt[m]> Don't get me wrong, this is a single core @ 1.0GHz. Nothing impressive and terrible slow, but that's probably the 1st easy to access (+ upstream support [not sure exactly status]) for Andes core IP.
<davidlt[m]> In worst case scenario at least some newer core IP for CI testing.
<cwt[m]> dual gigabit?
<davidlt[m]> Yup
<cwt[m]> that could be one hell of a firewall, well if the price is cheap
<davidlt[m]> Ah also Sophgo sg2040 is called "mango".
<davidlt[m]> Well I am not sure single-core @ 1.0Ghz might be capable of a lot of stuff without some accel.

<davidlt[m]> Sophgo has github account and a bunch of repos with various things (seems the source code is open).
<davidlt[m]> 64-cores, 16 clusters, 4 cores per cluster. 4 channels per SoC.
<davidlt[m]> Max 2S configuration for 128-core system.
<davidlt[m]> ZSBL code is also available.
<davidlt[m]> So far it looks like a large scale embedded SBC.
<davidlt[m]> (but the initial arm64 server was a "large SBC" too).
<davidlt[m]> Stil e-waste, but not a problem for Alibaba [Cloud], I guess.
<cwt[m]> sg2040 is a 120W processor
<davidlt[m]> I wonder if Alibaba is like Huawei and the plan is to iterate extremely fast.
<davidlt[m]> Yeah, so probably 200-500W for the 2S server platform.
<davidlt[m]> Also source code confirmed that it's C920.
<davidlt[m]> Not C910 like in TH1520.
<davidlt[m]> The biggest worry for me is trade war.
<davidlt[m]> China blocked Loongson exports, 4 months after US added relevant companies to entity list too.
<davidlt[m]> There is a big push to get Loongson supported upstream.
<davidlt[m]> Naturally SG2040 is significantly more powerful compared to Loongson announced SoCs.
<davidlt[m]> Thus I wonder will we manage to get it (i.e. buy) before trade wars blocks access to it (if at all).
<davidlt[m]> If you one want you probably should buy one ASAP.
<davidlt[m]> It's impossible to predict what will happen.
<davidlt[m]> Depending on the price this probably will be the best value product.
<davidlt[m]> A number of folks (in China) got EVB, and the Dev Kit is "Mango Pioneer" platform which will be on sale at some ponit.
<davidlt[m]> s/ponit/point/
<davidlt[m]> They have some strange hacks to get AMD GPU working, which is surprising. HD6000-series and AMD RX400 and RX500 series basically work on of the box for years.
<davidlt[m]> JH7110 upstreaming continues, but nothing new landed yet.
<davidlt[m]> More driver have been posted for a review thought.
