Brad LinderSpacemiT Vital Stone V100 is a RISC-V chip for servers. The 64-bit, 12nm chip supports the RVA23 profile, Vector 1.0 extension, and features like virtualization and encryption. <a href="https://buff.ly/40tJ1LW" rel="nofollow noopener" translate="no" target="_blank">https://buff.ly/40tJ1LW</a> <a href="https://fosstodon.org/tags/RISCV" class="mention hashtag" rel="nofollow noopener" target="_blank">#RISCV</a> <a href="https://fosstodon.org/tags/chips" class="mention hashtag" rel="nofollow noopener" target="_blank">#chips</a> <a href="https://fosstodon.org/tags/SpacemiT" class="mention hashtag" rel="nofollow noopener" target="_blank">#SpacemiT</a>

Jure Repinc :linux: :kde:🧵 2/nAt last I got that final but important piece for my RISC-V SBC ( <a href="https://mastodon.social/@bananapi" class="u-url mention" rel="nofollow noopener" target="_blank">@bananapi</a> BPI-F3): the cooler. Now I can finally start compiling some big chunks of code like Qt and KDE software. I do have distributed cross-compiling set up using Icecream, but apparently you can't prevent it scheduling compile jobs locally on SBC and only send them to more powerful computers.

Jure Repinc :linux: :kde:🧵 1/nJust got some RISC-V hardware goodies to play with in the following days/months: BPI-F3 SBC by <a href="https://mastodon.social/@bananapi" class="u-url mention" rel="nofollow noopener" target="_blank">@bananapi</a> with SpacemiT K1 8-core CPU supporting RVV 1.0 vector extensions. Hooked it up to the TV, booted it for the first time from a microSD with the default Bianbu GNU/Linux distro, so far so good. Will try to get Gentoo or openSUSE Tumbleweed with KDE Plasma/software running next.<a href="https://mstdn.io/tags/RISCV" class="mention hashtag" rel="nofollow noopener" target="_blank">#RISCV</a> <a href="https://mstdn.io/tags/RISC_V" class="mention hashtag" rel="nofollow noopener" target="_blank">#RISC_V</a> <a href="https://mstdn.io/tags/BananaPi" class="mention hashtag" rel="nofollow noopener" target="_blank">#BananaPi</a> <a href="https://mstdn.io/tags/BPIF3" class="mention hashtag" rel="nofollow noopener" target="_blank">#BPIF3</a> <a href="https://mstdn.io/tags/BPI_F3" class="mention hashtag" rel="nofollow noopener" target="_blank">#BPI_F3</a> <a href="https://mstdn.io/tags/SBC" class="mention hashtag" rel="nofollow noopener" target="_blank">#SBC</a> <a href="https://mstdn.io/tags/SingleBoardComputer" class="mention hashtag" rel="nofollow noopener" target="_blank">#SingleBoardComputer</a> <a href="https://mstdn.io/tags/SpacemiTK1" class="mention hashtag" rel="nofollow noopener" target="_blank">#SpacemiTK1</a> <a href="https://mstdn.io/tags/SpacemiT" class="mention hashtag" rel="nofollow noopener" target="_blank">#SpacemiT</a> <a href="https://mstdn.io/tags/RVV" class="mention hashtag" rel="nofollow noopener" target="_blank">#RVV</a> <a href="https://mstdn.io/tags/Bianbu" class="mention hashtag" rel="nofollow noopener" target="_blank">#Bianbu</a> <a href="https://mstdn.io/tags/Linux" class="mention hashtag" rel="nofollow noopener" target="_blank">#Linux</a>

Stefan Römer<a href="https://mastodon.giftedmc.com/@haui" class="u-url mention" rel="nofollow noopener" target="_blank">@haui</a> I couldn't resist to have a quick look into the device tree file(s) in the kernel sources of Bianbu Linux:see here: <a href="https://gitee.com/bianbu-linux/linux-6.6/blob/bl-v2.0.y/arch/riscv/boot/dts/spacemit/k1-x.dtsi" rel="nofollow noopener" translate="no" target="_blank">https://gitee.com/bianbu-linux/linux-6.6/blob/bl-v2.0.y/arch/riscv/boot/dts/spacemit/k1-x.dtsi</a>On a quick look (didn't check entry by entry) the 'riscv,isa-extensions' entries per cpu seems to match your table. Anyway as I said before, I think this does not need to reflect the real capabilities of the SOC too.<a href="https://fosstodon.org/tags/riscv" class="mention hashtag" rel="nofollow noopener" target="_blank">#riscv</a> <a href="https://fosstodon.org/tags/spacemit" class="mention hashtag" rel="nofollow noopener" target="_blank">#spacemit</a> <a href="https://fosstodon.org/tags/spacemitk1" class="mention hashtag" rel="nofollow noopener" target="_blank">#spacemitk1</a> <a href="https://fosstodon.org/tags/spacemitx60" class="mention hashtag" rel="nofollow noopener" target="_blank">#spacemitx60</a> <a href="https://fosstodon.org/tags/devicetree" class="mention hashtag" rel="nofollow noopener" target="_blank">#devicetree</a> <a href="https://fosstodon.org/tags/linux" class="mention hashtag" rel="nofollow noopener" target="_blank">#linux</a> <a href="https://fosstodon.org/tags/bananapif3" class="mention hashtag" rel="nofollow noopener" target="_blank">#bananapif3</a> <a href="https://fosstodon.org/tags/bpif3" class="mention hashtag" rel="nofollow noopener" target="_blank">#bpif3</a>

hauiI totally forgot to send my last toot so now you get two at once!I checked and found something rather unsettling: The <a href="https://mastodon.giftedmc.com/tags/spacemit" class="mention hashtag" rel="nofollow noopener" target="_blank">#spacemit</a> X60 core (seems to be part of the k1 processor) is marketed as RVA22 compliant but I dont think it is. So far, the following extensions do not seem to be included or I'm just blind: B, Za64rs, Zic64b, Zicbop, Ziccamoa, Ziccif, Zicclsm, Ziccrse.There are a ton more extensions that are included and some that are optional so there is room for error on my side.
