STRUCT SDCA_PDE_DELAY(9)

πŸ“¦ version 7.3.1, in nixpkgs unstable

πŸ¦‹ struct sdca_pde_delay(9) β€” from the Kernel API Manual, bestie πŸ’…

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. ✨


🌸 NAME 🌸

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 🫢)


πŸŽ€ SYNOPSIS πŸŽ€

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 😭 that's canon, leave it alone, we don't touch it.

πŸ‘‘ Members πŸ‘‘

  • from_ps β€” the power state being exited, aka the state you're leaving behind, it's giving "moving out" energy πŸšͺ
  • to_ps β€” the power state being entered, aka where you're headed, main character destination vibes ✨
  • us β€” the delay in microseconds switching between the two states. Lowkey the whole point of the struct ngl ⏱️

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 πŸ’–
