cik_irq_set(9)
π cik_irq_set(9) β the kernel API manual, bestie edition π
okay so welcome to the <pink>Kernel API Manual</pink>, babes β today we're looking at cik_irq_set(9) and honestly? it's a lil baddie with one job. let's get into it β¨
πΈ NAME πΈ
cik_irq_set β enable/disable interrupt sources π
π SYNOPSIS π
int cik_irq_set (struct radeon_device *rdev );
that's it. that's the whole vibe check. one argument, returns an int, iconic behavior fr fr.
π¦ ARGUMENTS π¦
rdevβ aradeon_devicepointer π«Ά that's your handle to the radeon device you're messing with, no cap.
β DESCRIPTION β
so like. this function enables interrupt sources on the GPU β think <purple>vblanks</purple>, <purple>hpd</purple>, etc. β and yes, it's the CIK flavor of that (as in, this one is for <hotpink>CIK</hotpink>) π
it returns 0 for success, and errors for failure π so always check your return value bestie, don't just yolo it.
ngl there's not a ton of lore here β it does the thing, it tells you 0 if it went well, and it hands you an error if it didn't. periodt.
