Select all SoCs which can boot mainline linux.

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

Is it all of them?

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
- 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.
- 286 Protected Mode is very different from 386 PM and there is no way Linux will would run on it.
- 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.
- If posted in the right circles, this might motivate someone to get something on a Spartan 6 that runs Linux.
- You can run a "soft" (semi-hard?) Processor on a Spartan, you could run Linux on that at least.
- I guess the blurry Samsung in the center is an ARM?
- 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...
With enough grit and time, yes :D

Edit: ok not mainline, but Linux in some form or another anyway.
- Here's a list:

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

The follow up question is what chip can run Doom.
- The one after that is just a panel of sixteen shoes, "Which of these can run a JVM?"

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

This is gold

It's mostly silicon.
- 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 ;)
- Do they get covered with mold?

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.

The mainline part is key.
- 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.
- ...and lack of "theory".

Not on the Harris, Qualcomm and Broadcom ones, those are modems. The Mediatek and TI Omap one I have no idea about. The SCEI one can only run YellowDog due to it being a PowerPC architecture.

Yellow Dog, there’s a name I haven’t heard in a while. Unfortunately it’s now long dead.

Debian at least still maintains a PPC version.
- That was a neat read, had never heard of it before. Yeah, besides like obviously IBM OSs and Debian I didn't know anything else that had power support.

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.

What LPI Exam is this

Lmao

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
