If we want to have computing freedom, we're going to need computers that are safe and don't lock us out. Having actually well designed architectures (x86 sure ain't it) would be nice too. RISC-V is a beam of hope: https://riscv.org/
- India is making progress on fabb'ing their own RISC-V chips https://fossbytes.com/linux-on-shakti-india-risc-v-processor-iitm/
- FOSDEM video on RISC-V https://fosdem.org/2018/schedule/event/riscv/
Got other interesting RISC-V links?
@cwebber In what way would you expect a RISC-V to actually improve user experience.
I dont think ive ever been "locked out" of my computer because of my choice of cpu...
- No consumer wants Intel ME (or AMD's equiv) low-level spyware, but except that Intel won't remove it because IIUC it's key to Intel's team-up with Hollywood's DRM stuff.
- Hardware bugs end up being system-wide bugs. See Meltdown, Spectre, but there are others too. Users have no control over fixing that stuff. There's no community opportunity to even *audit* it.
- We're moving into an era increasingly where it's very hard to install FOSS software on devices.
@cwebber All valid points. What does RISC-V do to address these issues. Just make it open source basically (a huge step in its own right).
@cwebber Awesome. I'm an EE and a CE. Just havent had time to catch up on the RISC-V stuff. So this is right up my ally. Thanks for the info.
@freemo Happy to spread the good word! ;)
The hi-five looks like a cool and powerful RISC-V dev board, but it's not on sale anymore afaict https://www.crowdsupply.com/sifive/hifive-unleashed
The HiFive1 is still available, but is less powerful than the HiFive Unleashed https://www.crowdsupply.com/sifive/hifive1
Still would be good for experimenting, though.
@cwebber I really hope we'll see another run of the unleashed, 900$ is kind of expensive for basically an rpi but at FOSDEM they said it would be 100 if they could commit to a run of 100k or something like that...
Would feed my addiction for home-servers on weird architectures :)
@cjd Yeah... also, I think Trump's trade war stuff is a total nightmare, but... I guess for this there may be an interesting side effect in that India and China are looking to free themselves from US companies, and look to be investing in RISC-V https://www.eetimes.com/author.asp?section_id=36&doc_id=1333476
Looks like Western Digital will be switching over to RISC-V too for all their computers that run your hard drive (yes, your hard drive does have its own computer)
@cwebber I recall someone installing Linux on a harddrive w/ a couple of ARM cores.
China used to be doing something with MIPS at some point, Loongson laptop, also Baidu is running everything on ARM cores...
@cwebber The HiFive unleashed should still be available, at least I ordered one only a few weeks ago
@cwebber though according to the updates they're sold out? This is strange, they did let me place the order.
@orionwl could be they just recently sold out
@cwebber The CPU is dead. It's death has been forseeable as long as I've been in software, which is thirty-five years now. We've reached the physical limits of throughput on a single core.
The future has to be massively parallel; and any architecture which isn't designed for massive parallelism is industrial archaeology, not the future.
@simon_brooke a compromised massively parallel system is still a compromised system
@cwebber Oh, sure. But the point is, building a processor which doesn't have at least six peer-to-peer buses is yesterday's game. It has no place in tomorrow's.
The actual instruction set is a separate issue - although my preference is keep it simple.
So, what Debian image is need for shakti?
Can't find a port / version that would work with RISC-V thou :(
