💤 cs_dsp_hibernate — the Kernel API Manual glow-up ✨

okay so bestie, this one's a kernel API page from the 9 manual (the kernel API section, yk) — and it's literally the nap button for a DSP 🎀

🌸 NAME 🌸

cs_dsp_hibernate — disable or enable all controls for a DSP 💤

✨ SYNOPSIS ✨

void cs_dsp_hibernate (struct cs_dsp *dsp , bool hibernate );

like, that's the whole vibe — one call, two args, no return, no drama 💅

🫶 ARGUMENTS 🫶

  • dsp — pointer to the DSP structure 👑 (your main character struct, fr)
  • hibernate — whether to set the controls to cache only mode 🧚

🦋 DESCRIPTION 🦋

okay so here's the tea ☕ when hibernate is true, the DSP is entering hibernation mode — the regmap is inaccessible, and all controls become cache only. like, they're not touching the hardware, they're just vibing in memory 🙈

when hibernate is false, the DSP has exited hibernation mode. and if the DSP is running, all controls are re-synced to the DSP ✨ lowkey the wake-up stretch after the nap, periodt.
