Modern USB keyboards need to be asked what’s being pressed by the CPU multiple times a second, but old PS/2 keyboards will actually interrupt the CPU to send the key press command
It’s kind of a tradition among the r*ddit refugees from s*bs like linuxmemes and linuxmasterrace. Posting things that aren’t strictly linux-related, but would still be appreciated in general by computer nerds.
I don’t get it…

Oh, didn’t actually know what’s being done behind the scene…
Why is this relevant to Linux only?
It’s not
Hm… then why is it posted in a Linux comm?
Because it’s funny, there’s nothing that you don’t already know.

Ah, didn’t know that 👍.
I see you had interruptions masked.
Why e in this context? I have seen
sei()
andcli()
before, but notE
.That’s the very important information you got from the keyboard.
Some context may come later, but it will take ages.
Thanks, apparently I can’t read. I somehow missed the top right yellow speech bubble.
