Re: RISC-V questions

[Lucretia]

It seems the Pioneer and Sifive are desktop boards from what it looks like. The 
Lichee Pi looks cool too. I can't find Oasis from the link. I assume the 
Pioneer/Sifive need a CPU while the Lichee Pi is more like R-Pi? Duo looks fun 
too, you can build security cams like Big Brother.

I've only used R-Pi and intel/AMD, what kind of setup are the Risc-V you are 
looking at? On Wikipedia it says there are embedded, desktop, and servers that 
use it. I can't say I'd be in for joining with a one for me, one for a

RISC-V questions

[Peter J. Philipp]

Hi,

I have very little insight other than google news what it means that the
flagship of risc-v, a company called sifive, had a lot of layoffs.  I have
heard scarecrow stories of the US Chip Act or something that the US is moving
anti-riscv.

I have three riscv computers right now, all of them come out of China and
one of them uses sifive cpu's, so it's half american.  I had planned to
buy more american risc-v but the politics around chips and riscv aren't
particularily positive.

I can probably forget buying a Sifive/Intel P550 now.  It was in competition 
with a Lichee Pi or a Milk-V Oasis-type board.  And now the choice from three
became two.  I want this as my workstation.  I wrote about this before and it
was suggested to me that I get a Milk-V Pioneer but I can't afford the
electric bill for that, I figure.

So, I have to ask does anyone have interesting insights as to perhaps US or
European riscv efforts?  I would buy if affordable and competive with what
Chinese manufacturers are offering.  I do believe risc-v with its openness
is my favourite architecture so far.  Also, I told my close ones, that I 
won't be buying for just myself but also for someone at OpenBSD (so twice) 
as riscv is still bleeding edge somewhat especially on the desktop.

I was very happy with what was announced with the Oasis board.  The price is
right ($120) to perhaps get two boards to OpenBSD here, given that someone 
at OpenBSD wants to give it a turn to do development on it, and they might
be able to do it with two+ people.  I have been looking around others who in
the past wanted to donate and we could possibly get an even larger donation
together, given, only if there is interest in the OpenBSD developer community.

That was a few weeks ago before Oasis was announced for the Lichee Pi, but I
think the Oasis to me is a lot more interesting than a Lichee Pi and may be
cheaper in the end.  One particular nice thing about it is my interpretation
that it has non-soldered on RAM.

Let me know if you have some answers and if potentially anyone is available to
receive Oasis-type boards perhaps after Christmas, I'll be following up with 
a purchase in March 2024 or so.  By then there might be even sweeter deals 
considering how fast this all moves, we should see then.

Best Regards,
-peter

RISC-V : Interested by the VisionFive2 ?

[Vincent Finance]

Hello everyone,
I was looking at the riscv64 page by curiosity and I noticed you added the 
StarFive VisionFive SBC in the list of supported hardware. Recently, the same 
company released the VisionFive2 which is an updated version of this board and 
it seems we can buy some on AliExpress.
I am considering to buy one for testing the RISC-V platform and I wanted to 
know if some OpenBSD developers are interested in getting this version of this 
SBC ?

I am living in France, near Lyon, but I can ship it in an European country if 
needed.

Let me know if you are interested :)

It currently does not work with OpenBSD. It uses the Allwinner D1, which has
DMA issues. Another thing that would need to be worked out is the panel
output support.

I was going to try and take a whack at these issues but I probably won't have
time.

[RISC V] OpenBSD/riscv64 vs devterm R1 kit

[Alexander Shendi]

Hello @misc world,

I couldn't find any mailing list for the OpenBSD RISC V port, so I'm posting 
here. If there is a better place, please give directions. Also feel free to 
forward to anyone who may be interested or of help.

Does anyone have experience with the RISC-V devterm kit? Apparently it's quite 
easy to assemble.

Drawbacks:
* Slowish CPU
* CPU design not really open
* Apparently a bit awkward to use

Could it run OpenBSD/riscv64, or is only the HiFive board supported?

https://www.clockworkpi.com/product-page/devterm-kit-r01

I would volunteer to buy one or two for OpenBSD devs, but I don't know if they 
could be used for serious development work.

Many Thanks in advance,

Alexander

I hear it's only truly open if you're part of their exclusive "club".
Otherwise it's as much "you take what you're given" as any other
architecture.



RISC-V architecture, and a few implementations are released under BSD licence.

In contrast, ARM Holdings or MIPS Technologies don't allow others to use their
architectures without paying royalty fees. For example, the Chinese Academy of
Sciences designed Loongson processor from the scratch, but had to pay to
MIPS Technologies in order to base it on the MIPS IV instruction set.

If you're willing to do a port, I doubt any here could stop you.  RISC-V
hardware needs to become available though before such a port will become
any practical use.

I'm not sure what your point is.

URLs and PDFs don't help the software development process.

PDF isn't turing complete, so you can't write a cpu emulator in it.

Press releases are not helpful.  Only hardware in-hand helps.

I've seen on twitter a guy who booted NetBSD on RISC-V spike sim. That would be 
probably better code
if you consider porting of OpenBSD to RISC-V since NetBSD and OpenBSD are more 
close together.

Re: Embedded FreeBSD on a five-core RISC-V processor using LLVM

[Dinesh Thirumurthy]

I believe a few will be interested in OpenBSD on RISC-V hardware.

This is the first time, a BSD is booting on RISC-V hardware.
Looking forward to get OpenBSD on RISC-V hardware.

So, it might be interesting to look at this talk and associated tracks.

OpenBSD on Open Source CPUs (like Shakti RISC-V) would make a great firewall.

Thanks.

Step one: write a bunch of code.

OpenBSD has not been ported to RISC-V yet, so you (or someone) would
have to do that work.

Porting OpenBSD to any new architecture would be welcome, but so far
nobody has done it.

Good luck!

Our emulators/qemu port has already supported RISC-V and it runs quite well.
If you have time maybe you can test the riscv-elf port?

FPGAs capable of doing anything big take lots of power and generate lots of 
heat. They are far from ideal as a platform base, but great for testing if your 
hardware can be described in VHDL or Verilog. The work to go from that to an 
ASIC is immense and will take significant backing, which makes the industry 
support for RISC-V rather interesting. Everyone wants royalty-free hardware in 
their little devices, I can't blame them.

Hi!

RISCV really interests me!  But the porting effort for this is probably
above my head.  In the past in risc-v threads I posted a riscv-qemu build
procedure.  I revisited this today and followed my own steps.  After a bit
of trying I finally got it compiled.  I blogged about this experience:

http://www.centroid.eu/blog/c?article=1526665139

Realistically if you want to run BSD on RISCV you can do it through this
way.  You don't need to buy the hardware, unless you're seriously good with
porting.  My emulation was on FreeBSD, thanks to those folks for makign a
bbl available (so I don't have to install FreeBSD and crosscompile).

Best Regards,

PS: I've been following Talos 2 as well, and really like it but again, that's
the same as with the RISCV issue, I lack the clue to port this.  I'm going
to learn about RISCV assembly first and then perhaps learn about POWER
assembly, perhaps I can build a compiler.  (I have access to POWER hardware,
but will need to ask permission).  Once that is done I'm ready to help

Indeed! Very nice offering, especially recent Lite. On the other hand I can't 
resist but it looks to me more and more like swan's song of POWER world. Such 
machine should be here 5 years ago at least if not right after demise of Apple 
from PowerPC world. That to just keep engineering on the platform. Now, OpenBSD 
is still supporting PPC but just in 32bit and that even on old and drying 
supply of 64bits Apple's G5s.

Foolish estimation: if you have a set of machines you would need 2 years and 
2-3 engineers to work on this platform to get it somewhere. Lot of effort to 
just support very fragile world of POWER/PowerPC. Even Freescale, err, NXP, 
err, Qualcom seems to be leaving it for ARM. Why would anyone else stay/support 
it? IBM is leaving hardware world slowly more to services so you can spent a 
lot of time and then just wake up one morning finding out that there will be no 
future POWER chips from IBM anymore -- that's depending on one vendor CPU 
supply. Fragile position.

'90s taught me that movement is done from the down to up and not from up to 
down. Intel killed all those nice workstation provides of '90s very slowly, but 
killed them at the end. It was not Sun/Digital/SGI killing intel together. 
Intel from the down of slow 486, then Pentium and then final straw was Pentium 
Pro. Sudenly PCs were faster and there was no need to stay on more expensive 
nice machines -- except perhaps for software support.

The question is, if something like that can't happen between ARM and Intel and 
then later on between RISC-V and ARM. For example Cavium's ThunderX2 looks very 
nice. In RISC-V, please see presentation of Esperanto Technologies (high-speed 
chips with a lot of various accelerators done on 7nm TSMC).

Yes, open, but do I really need to move back to Linux world? I kind of left it 
(as main workstation OS) to OpenSolaris recent years migrating from it to 
OpenBSD. Do I really need to go back to Linux mess? My bet is on ARMv8 and 
later on RISC-V. I hope both future is more bright than of IBM's hardware 
division... And life's simply too short to bet/invest a lot of time on yet 
another architecture and see its failure...

Indeed! RISC-V is making progress. For plain programmers this is probably not 
yet the right set of hardware as (1) system spec of RISC-V is not finalized yet 
(IIRC!) and (2) speed of the board CPU is probably lower than speed of Qemu 
emulation on high-speed xeon CPU.

Also, w.r.t. price, it's a bit prohibitive indeed. IIRC promise was to have 
both boards on one board and for ~$1000 but I may be mistaken on this. Anyway, 
this is just first bird and I hope there will be more comming. Especially the 
promises of Esperanto Technologies look really promising. Future is open and 
interesting!

Neat, but horribly slow and expensive. Raptor CS, on the other hand, are 
releasing the POWER9 based Talos II Lite soon, and also (apparently) the bare 
motherboard without chassis. Info at raptorcs.com

It'll probably still be a bit slow and expensive compared to a Xeon, and it 
won't work run OpenBSD out of the box, but it is open.

Awesome!  That basically did what I had planned next, so then I can look at
getting an OpenBSD kernel cross compiled (perhaps with a freebsd locore?) and
that would further my goal of booting a bsd.rd or something in qemu.
