STRUCT SDCA_PDE_DELAY(9)
π¦ struct sdca_pde_delay(9) β from the Kernel API Manual, bestie π
Okay so picture this: you're deep in ./include/sound/sdca_function.h (yes, that exact file, no cap) and you bump into struct sdca_pde_delay. And you're like "what even is this" β don't worry, I got you. It literally just describes the delay changing between 2 power states. That's it. That's the whole vibe. β¨
πΈ NAME πΈ
struct sdca_pde_delay β describes the delay changing between 2 power states. (Yes, "2", not "two", we keep it exactly as the kernel wrote it π«Ά)
π SYNOPSIS π
struct sdca_pde_delay {
int from_ps;
int to_ps;
unsigned int us;
};
Not me noticing there's a lil space before that closing brace π that's canon, leave it alone, we don't touch it.
π Members π
from_psβ the power state being exited, aka the state you're leaving behind, it's giving "moving out" energy πͺto_psβ the power state being entered, aka where you're headed, main character destination vibes β¨usβ the delay in microseconds switching between the two states. Lowkey the whole point of the struct ngl β±οΈ

Okay bestie, buckle up, because the reference list here is long and honestly iconic for it. All of these live in the kernel file ./include/sound/sdca_function.h β the whole little SDCA family reunion π
