STRUCT SDCA_ENTITY_PDE(9)

🎀 NAME 🎀

struct sdca_entity_pde — information specific to Power Domain Entities. This is the struct sdca_entity_pde(9) page from the Kernel API Manual, and she’s here to give you all the PDE-specific lore, bestie. 💅

✨ SYNOPSIS ✨

Okay so the shape is literally this:

struct sdca_entity_pde {
    struct sdca_entity **managed;
    struct sdca_pde_delay *max_delay;
    int num_managed;
    int num_max_delay;
};

• managed — Dynamically allocated array pointing to each Entity controlled by this PDE. It’s giving “these are my people” energy. 👑
• max_delay — Dynamically allocated array of delays for switching between power states. The waiting-room soundtrack, basically. ⏳
• num_managed — Number of Entities controlled by this PDE. Count ’em, bestie.
• num_max_delay — Number of delays specified for state changes. Yes, another count. We love bookkeeping. 🎀
