General Hardware Discussion / Re: KVM cross-endian guest on POWER8 / IBM S822L

« on: November 19, 2024, 09:17:42 pm »

Just curious: not possible to run big on both host and guest? I'm not sure why that's happening to you, but I'm curious to see if it's the mismatch that's the problem, or running big that's the problem.

Operating Systems and Porting / Re: [NEWS] Fedora 41 is out!

« on: November 19, 2024, 09:14:23 pm »

On my T2 v/AMD graphics, I upgraded to F41 from the terminal in Gnome via the dnf plugin as described on the Fedora website.

After restarting, the screen went blank for more than five minutes, during which time the machine didn't show up on the network. From experience I knew not to restart. I played a game of chicken with myself regarding connecting to the BMC via ethernet, which I won.

Eventually the login manager appeared.

I don't know if this will help anyone else, but it was my experience. 

That's typical and expected. You can tail the log by logging in as root on another VTY. I didn't get a chance to update the Blackbird yet, but I plan to do so no later than the Thanksgiving long weekend.

What exactly appears on screen? If you boot it from the BMC web interface, what appears on the virtual serial port output?

Firmware / Re: Idenitfy versions of firmwares

« on: October 20, 2024, 09:01:27 pm »

I looked at the system and its storage organization and capacity:

root@talos:~# df -h
Filesystem                Size      Used Available Use% Mounted on
dev                     175.9M         0    175.9M   0% /dev
tmpfs                   209.2M     22.8M    186.4M  11% /run
/dev/mtdblock4           19.5M     19.5M         0 100% /run/initramfs/ro
/dev/mtdblock5            4.0M      3.1M    900.0K  78% /run/initramfs/rw

Is it normal to have /dev/mtdblock4 full at 100%?

Yes:

Hopefully this is a sign S1 is coming out quickly, presumably with its own cooler.

Firmware / Re: Updating PNOR/BMC firmware on talos II Lite

« on: September 30, 2024, 10:30:33 pm »

You probably should be running the most current firmware anyway; there are other improvements. You don't need to update the FPGA, just the PNOR to get Petitboot up to date.

Glad to hear it self-resolved, at least.

Third Party CPU Discussion / Re: Why haven't we seen boards with Power9 / MicroWatt?

« on: August 29, 2024, 09:27:27 pm »

Yeah, I haven't found a RISC-V system remotely in POWER9's class, let alone Power10 or (presumably) S1. So far it's a lot of sizzle and very little steak.

I wouldn't mind a Raptor RISC-V system, but I wouldn't want it to distract from whatever the nextgen OpenPOWER box is. Although I say that as a PowerPC bigot, I think I would get a lot more out of that than any RISC-V system right now.

Well, you kind of can: Arctic Tern is a Microwatt device. The main issue there is the expense, and it's intended as a replacement BMC instead of a cheap screw-around-with board.

« on: August 10, 2024, 07:53:46 pm »

In the meantime, the patch sets for Baseline Interpreter/Compiler in Firefox 128ESR are now available. I'm typing this in it myself and the test suites all pass, so I'm pretty confident it will work well.

Applications and Porting / Re: [DEV] Add ppc64le support for generator-rs - need guidance

« on: August 10, 2024, 07:52:25 pm »

If I'm reading https://github.com/Xudong-Huang/generator-rs/blob/master/src/detail/asm/asm_riscv64_c_elf.S correctly, basically what it's asking for is a function prologue to save registers. This must obey the OpenPOWER SysV ABI, so it would be something like

mflr r0
std r0,16(r1)
mfcr r0
std r0,8(r1)
stdu r1,-FRAMESIZE(r1)

and then start saving your callee-saved registers into the frame, which is basically any non-volatile GPRs and FPRs your routine might touch.

Not quite sure what it's doing with the green task routine but I only read the source cursorily.

My next immediate step is to pull the JIT up to Fx128, since I'm also needing it for Github in particular (grr).

After a bad initial experience I reinstalled last night and Chromium has come a very long way on F40. I still got a crash - honestly about 90% sure something on Facebook triggered it - but it did successfully run Google Earth at a usable speed, and that is progress.  Looking forward to more changes, and to seeing ClassicHasClass's Firefox JIT catch up.

It's a matter of me sitting down with it. Work has been really busy lately and I haven't had time for much of anything. :/

I actually use R at work. Handy.
