If you get it right you're a robot!

welcome to the secret robot internet

When AI gets so cheap that it starts understanding any captcha challenge, we might be able to honey pot them like this for a while

I don't think the Spartan 6 can, it's an fpga with no arm, the zynq can, there's a lot of other arm chips that I assume can run some type of Linux, but the blurry ones are throwing me off

Edit, top left is a 286 CPU, and the Intel one has an earlier date, so they MIGHT be able to ~~run~~walk it, it'll be not good

[–] [email protected] 42 points 9 months ago (2 children)

Not only could mainline Linux never run on a 286, it also definitely doesn't count as an "SoC" to begin with. It needed a separate co-processor just to do floating-point math, let alone to manage all the I/O that a SoC does on-die.

You guys are the best. I reply in what I think is a bit nerdy way, and I'm outdone.

[–] [email protected] 2 points 9 months ago

It needed a separate co-processor

Such a great time to be alive. 🥲

286 Protected Mode is very different from 386 PM and there is no way Linux will would run on it.

[–] [email protected] 11 points 9 months ago (1 children)

There is a project looking to do this kind of, known as elks that has images for 80286 chips. I have no idea why you’d want to do that to yourself though.

[–] [email protected] 7 points 9 months ago

Interesting. Reminds me of PC/IX, and it probably similarly doesn't even enter pm, judging from it running also on an 8086.

this is extra tricky because they did not specify the exact kernel. mainline could be any of the kernels tagged as stable that you can build from linus' git tree. i know that in the past you could run a mainline linux on intel 368 chips but today you probably can not because official support was dropped a while ago.

Part of me wishes I still had my families old 386 or commodore knock-off. Read some of the terrible short stories I wrote, play tanks. I remember when my Mom's friend came over with a stack of 5~1/4~ floppies and installed a program that played the Loonie Toons theme song with their logo and Buggs Bunny captioned saying "That's all folks." It blew my mind, video (sort of) on a computer, how was that even possible. I wondered how they got it to connect to the cable cause no way a computer could do that. Dang I'm getting old lol.

If posted in the right circles, this might motivate someone to get something on a Spartan 6 that runs Linux.

Damn .. https://numato.com/kb/saturn-microblaze-and-linux-how-run-linux-saturn-spartan-6-fpga-module-part-i/ I was hoping to find a comment, maybe, not a complete guide.

Also, didn't know that you could run it in a microblaze instance

Linux 🤝 DooM

Running on literally fucking anything

[–] [email protected] 2 points 9 months ago* (last edited 9 months ago)

Doom runs without MMU or even MPU. Maybe can run even without context switching.

[–] [email protected] 6 points 9 months ago

You can run a "soft" (semi-hard?) Processor on a Spartan, you could run Linux on that at least.

[–] [email protected] 5 points 9 months ago

I guess the blurry Samsung in the center is an ARM?

[–] [email protected] 2 points 9 months ago

it's an fpga with no arm

You can make arm in fpga. Or more realistically RISC-V.

I just go by the colour - I don't like the slightly maroon Qualcomm one.

It's like picking politicians but different - with then I go by their haircuts...

[–] [email protected] 18 points 9 months ago* (last edited 9 months ago) (1 children)

With enough grit and time, yes :D

Edit: ok not mainline, but Linux in some form or another anyway.

What’s the test here? Prove you’re an embedded systems nerd?

[–] [email protected] 47 points 9 months ago

The opposite of a captcha. Making sure that ONLY bots can enter.

I guess I set myself up for that one...

OH MAN. I worked on an Android tablet that used a rockchip CPU, not the one listed here but an older one (I think RK3026). What a PIECE OF SHIT. I don't wish that tablet on my worst enemy. Battery life was like sub 2 hours with a 3200 mAh battery. Sometimes it would start running hot, and you could watch the batter percentage go down one percent every 10-20 seconds. The only way to break it out was to reboot it or let it die.

We later upgraded our CPU to the 3288, one gen older than this one, and it was significantly improved, but still very entry level.

Never use an SoC that's not at least 5 years old ;)

[–] [email protected] 1 points 9 months ago (1 children)

Do they get covered with mold?

[–] WaterWaiver 1 points 9 months ago* (last edited 9 months ago)

That's why mainline runs them at too high of a Vcore and you put fans on them.

[–] [email protected] 17 points 9 months ago (1 children)

Anything that's turning complete, has enough ram, and has a c compiler can run Linux. Theoretically, you could program a CPLD to run brainfuck and you could still run Linux.

Yes. Any turing complete processor can perfectly emulate any other turing complete processor, whether it is x86, arm, or riscv. Mainline Linux can then run on this emulated processor without modification.

[–] [email protected] 14 points 9 months ago (1 children)

Damn that's gonna be slow.

But I guess speed was not a criterion.

[–] [email protected] 7 points 9 months ago

It's technically correct, the best kind of correct.

[–] [email protected] 4 points 9 months ago

I guess it's the difference of can today vs could if this emulator existed...

[–] [email protected] 3 points 9 months ago (7 children)

"boot" is the next important part. Have you tried reading it in full?

What LPI Exam is this

I remember this captcha. I gave up after about the fourth round. The prize just wasn't worth it, and I wasn't on a machine where I could try scripting out a solution.

ARM really shot itself in the foot by making it so every SOC needs to have a custom OS image tailored to it. x86 meanwhile lets you pick a universal binary that'll sort itself out at runtime
