Oh neat, we have a dedicated RISC-V thread now I thought this was interesting, looks like some chinese company is going to be selling a full "PC" with an AMD GPU https://www.tomshardware.com/news/milk-v-offers-a-trio-of-risc-v-raspberry-pi-alternatives quote:If you don't want to spec your own Pioneer, then the Pioneer Box is a ready-to-use RISC-V PC that provides between 32 and 128GB of RAM, a 1TB NVMe SSD, an Intel X520-DA2 network card, and two 10Gbps SFP ports. GPU duties fall to the AMD R5 230 — not a GPU on our list of best GPUs, but it'll get the job done. Power is provided by an MSI A350 350W PSU. Very interested to see where this goes. Not sure how much of this mfg in china, or if they're getting the chips from taiwan

Commercial products that aren't hobbyist/dev boards beginning starting to roll in. This one looks like one of those 2x2x.75" micro routers. The article says the company is trying to convince someone to port openwrt to it https://liliputing.com/this-2-inch-square-board-is-a-dual-port-ethernet-router-with-a-risc-v-processor/ Pretty minor but I'll take it for now

I can see china (and russia? if they ever develop a modern IC industry) going all in on RISC-V and being a leader in that space, if only to fully divorce themselves from western x86-64 and ARM, which seems like a very traditional isolationist china thing to do. I have already bought two RISC-V boards (one arduino style, M0(?) instruction set compatible, one raspberry pi style SOC) from China, no idea what country they were fabbed in. The dev pipelines for RISC-V are pretty ok already, even rust has decent support for embedded riscv, and in ten years sure seems like it'll be a good option, especially if it's a couple % cheaper.

https://www.phoronix.com/news/Debian-Official-RISC-Vquote:Debian 13 "Trixie" has been aiming for official RISC-V support and indeed it will happen: RISC-V has now been promoted to an official Debian CPU architecture. While long available as a Debian port, as of this weekend RISC-V 64-bit is now considered an official Debian architecture.

China seems pretty heavily invested in RISC-V. Building a chip from the ground up with a standard architecture seems like a great way to build a core competency, and then lock all their vendors into building their weapons with domestically supplied RISC-V. That's mostly speculation but uh seems like what they're doing. I can already buy RISC-V powered boards on ebay for under $10, it's not going anywhere. Also most of the RISC-V base instruction set is based on the patented ARM Cortex M0 instruction set... whose patent has expired. There's a lot of base compatibility there. Arm 2-9 are largely extensions of the original M0 set SiFive is a tech company in a historically unfriendly funding period, makes sense to cut things down to the bone, especially as a company heavily invested in R&D, until funding becomes more viable once again

BobHoward posted:Do you start to see why I'm reacting like this? The ISAs are observably quite different, nobody sane would even want to crib from ARMv3 (excpet perhaps in extremely narrow ways), the backgrounds of RISC-V's architects wouldn't lead them to take much from ARM, and said architects have confirmed that their work most closely derives from the Northern California RISC tradition. Yeah I definitely get what you're saying Google history thing is running really slow for queries going back more than a year but it relates to the "Amber Core" which is ... I think... an open source implementation of the ARM v2a instruction set.

There's some lobbyist shenanigans going on behind the scenes, probably; Intel bought up a big stake in ARM right before they went public, and investors are trying to protect their investment in ARM My guess is that in 15 years BRIC will run on RISC-V and NATO will be on x86-64/ARM What a stupid slap flight. An ICBM will run on an at mega 328, and fighter jets etc are built in such laughably small numbers anyone can import the thousand or so high end industrial cpu needed for those systems. There's what 850 F-35 jets on the planet? How many gaming laptops can you fit in one suitcase? 20? 10,000 laptops in a single shipping container?

in a well actually posted:https://www.hpcwire.com/2023/11/08/china-deploys-massive-risc-v-server-in-commercial-cloud/ Some really (really really) crude benchmarks show the sophon sg2042 at about 1/4 to 1/3 the speed of a 16 core, 32 thread amd ryzen 3950x. ZIP decompression isn't a very good test, but it's something. Even 1/10th performance is "good enough" for the vast majority of daily tasks https://forum.sophgo.com/t/risc-v-public-test-platform-released-7-zip-test/263 If that is developed and manufactured 100% in-country then I think the cat is out of the bag on containing China's CPU ambitions. I would expect BRIC are all focused on developing their own microprocessor industries at this point. If we were going to build walls to protect this technology, we should have been doing it in the 1980s. We're about 40 years too late. 48 1U systems isn't a lot, but like everything in the semiconductor world, once you get your yield up, you can print chips forever on that process very reliably

RISC-V based "gaming console" https://www.tomshardware.com/pc-components/cpus/risc-v-handheld-gaming-system-announced-linux-as-the-basis-for-a-retro-gaming-platform There's a huge cottage industry of ARM based steam deck looking devices that come preloaded with a bunch of emulators like Sega Dreamcast, SNES, PlayStation 1/2 and hundreds of roms I guess this is the "if you build it they will come" moment. Now all the retro emulators have an excuse to add RISC-V as a build target Looks like price point around $250 USD, maybe

RISC-V is almost exclusively supported by Linux, so it's (probably) just a RISC-V Linux binary and talks to the kernel for audio video bindings. Presumably whatever custom kernel was compiled for the device should have adequate GPU support and whatnot. Ubuntu has had official support for RISC-V since the April 2020 release so presumably by the time this ships RISC-V will have been mainline for 4 years I'm increasingly of the opinion that the US government missed the boat on containing Chinas CPU capacity by about five years

Twerk from Home posted:Well, we are trying anyway: https://www.reuters.com/technology/export-controls-hit-chinas-access-arms-chip-designs-ft-2022-12-14/. Yeah my dad worked at Intel as an engineer for like, 3-5 years while i was a kid so I'm probably ever so slightly more attuned to processor stuff in the news than your average autist. And the news feed algorithm is going to feed me a steady drip of news on the topic. And this is the RISC-V thread, so And yeah the Biden administration has been making statements and actively locking down CPU technology share for... At least the last year? I think he's made public statements every week for the last two months. We went from 0-100 on CPU policy lock down recently it seems topical. Members of Congress (2?) have made public statements about shutting down RISC-V knowledge transfer recently, which is pretty weird Outside of the recent change in policy I have not a lot of interest in China. Although I guess full disclosure I've been to Hong Kong like, three times, but I travel a medium amount in the region by American standards Edit: oh and I'm writing some software that's targeting RISC-V specifically
