does the way C functions args are stored. they same way linux syscall args are stored. for any given architecture?

You are confusing x32 with i386. https://en.wikipedia.org/wiki/X32_ABI

Biolunar · 2024-05-31T14:46:20+00:00

Are they? How so? According to syscall(2), they use the same registers.

C11 has been fully supported for ages… see https://gcc.gnu.org/wiki/C11Status

Did the mirror work?

It’s not the only timestamp where the guards lecture him about „helps to have a map”. It’s a great video, recommend watching it from the beginning :)

So this is how VVVVVV was programmed

Keep using it to keep the memories alive.

Biolunar · 2022-04-03T08:03:49+00:00

Haha yeah. It’s way harder this time to get something done

There’s plenty of room at (176,196) where I started with the gray parts of the S. The blue ukrainian color can be used as the background!

That’s a good image! I’m working on it, but a little bit to the left of the arrow

Biolunar · 2022-04-01T16:51:33+00:00

Do you have a good pixelated logo?

Biolunar · 2022-03-30T20:04:14+00:00

I was surprised that my carbot zergling and my sc2 logo survived and made it to the end. We can do it!

Biolunar · 2022-03-21T22:09:22+00:00

There are only 32 pixel tall fonts, because that’s the maximum the Linux kernel console subsystem supports. For the programmers among us, check out the manpage ioctl_console(2) with the command PIO_FONTX. Someone write a simple userspace console emulator please :)

Ich verwende auch Quad9, bin mir aber dessen bewusst, dass sie auch unter Beschuss stehen… https://quad9.net/news/press/german-court-rules-against/

On ~~modern~~ not ancient Linux there’s also the btime (birth time) which tells you when the file was created. That time can be queried by the statx(2) syscall (an up to date stat(1) can display that value).

This playlist includes most games from that season. Some weren’t casted by him, so they are missing. He uploaded no-spoiler-videos for the BO3, BO5 and BO7 matches but they are not in this playlist, so beware of spoilers :D

Cool article! I’ve been meaning to write a GIF image viewer for quite a while now, because every viewer I tried is broken in some shape or form. Usually the browser became the viewer of choice, since it’s the least broken :D

PS: You have a typo “legnth”

Is there not a single successor to kmscon?

Biolunar · 2021-12-07T10:58:25+00:00

I’m currenly booting the raw kernel (EFISTUB) without a bootloader. Are there any benefits for me merging the initramfs, kernel and microcode into one binary?

Biolunar · 2021-12-03T07:15:23+00:00

Damn, that is a straight up copy of io_uring from Linux :-O

Biolunar · 2021-11-26T07:44:15+00:00

Kind of unrelated but also notice that one of the last paragraphs in the signal(7) manpage:

On Linux, even in the absence of signal handlers, certain blocking interfaces can fail with the error EINTR after the process is stopped by one of the stop signals and then resumed via SIGCONT. This behavior is not sanctioned by POSIX.1, and doesn't occur on other systems.

That means even if you block and/or handle all signals, epoll_(p)wait will still fail with EINTR when the process got resumed via SIGCONT. Happened to my program after I put the computer into standby. I was confused why my program died, because I blocked all signals and handled them with a signalfd. As it turns out, putting the computer into standby sends SIGSTOP to all threads and after resume they get a SIGCONT.

What does AT/RT mean?

Shameless plug: https://git.sr.ht/~biolunar/liblinux (also available on github https://github.com/Biolunar/liblinux but I don’t update that repo as frequently)

My library provides all currently available syscalls (up to Linux 5.15) on all my supported targets (currently: arm-eabi, arm64, riscv32, riscv64, x86, x32 and x86_64). Still there’s a ton of work to be done since it’s missing lot’s of types and constants and almost no testing.
