PS/2 Port on its way to harass the CPU
Seems the CPU has become the bully these days:
CPU: hey keyboard do you have anything for me?
CPU: hey keyboard do you have anything for me?
CPU: hey keyboard do you have anything for me?
CPU: hey keyboard do you have anything for me?
CPU: hey keyboard do you have anything for me?
CPU: hey keyboard do you have anything for me?
CPU: hey keyboard do you have anything for me?
CPU: hey keyboard do you have anything for me?
Keyboard: E

My grandpa always used to say that computers used to be way better before they became electrical.
Ah, yes the good ol days of punch cards, switch boards, mechanical operators and electron tubes, when will the youngins learn that their fancy transistors are for pussies
Personally I inscribe all of my code into binary on a fired clay tablet and store it in a cave for archival purposes
No I meant the real computers
Low level accountants in the early 20th century.
No binary monstrosity could ever replace just doing it in your head.
I always appreciated Dunes idea of a mentat, basically an accountant trained from birth and juiced up on brain steroids to have equal computing ability to a high level AI. Usually when I think of the way human conciousness may evolve and trancend its current capabilities my mind goes right to the psychadellic-bro conciousness expansion and non-localized astral projection stuff, its interesting to consider there are other potential paths to augmenting human conciousness and what other boundaries could be pushed.
SMM GO BRRR
A disgusting fifth glyph? In MY list of funny pics? I may throw up.
Is there not multiple in your name?
He's a traitor.
IDs don't count. Would fail too many for a hard to fix thing.
Ah, a man of abundant class. How wondrous to run into you on this platform.
assembly flashbacks
I don't get it...
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
Oh, didn't actually know what's being done behind the scene...
Why is this relevant to Linux only?
I see you had interruptions masked.
Why e in this context? I have seen sei() and cli() before, but not E.
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.
Int 8 would like to say hello. And you better not take too long.
Good old interrupts, how come we don't do it like that for drivers anymore
We still kinda do, just depends on the kernel you're using. On Windows any IRQL > 2 is pretty much instant like the bird
