STRUCT ACPI_PROBE_ENTRY(9)

💅 struct acpi_probe_entry(9) 💅

okay so this is from the Kernel API Manual, bestie, and we're talking about a boot-time probing entry. It's giving "little struct with main character energy," and we're gonna go through every member, no cap. 🫶

📛 NAME 📛

struct acpi_probe_entry — boot-time probing entry. Literally what it says on the tin, and yes bestie, we're covering all of it. ✨

🧚 SYNOPSIS 🧚

struct acpi_probe_entry {
    __u8 id[ACPI_TABLE_ID_LEN];
    __u8 type;
    acpi_probe_entry_validate_subtbl subtable_valid;
    union {
      acpi_tbl_table_handler probe_table;
      acpi_tbl_entry_handler probe_subtbl;
    };
    kernel_ulong_t driver_data;
 };

🎀 Members 🎀

• id — ACPI table name. That's the name, periodt.
• type — optional subtable type to match, but only if id contains subtables. Situational icon. 💅
• subtable_valid — optional callback to check the validity of the subtable. Like a vibe check for subtables, but make it callback. 🔥
• {unnamed_union} — anonymous. No name, just anonymous union energy. 🙈
• probe_table — callback to the driver being probed when table match is successful. Slay when the table matches. ✨
• probe_subtbl — callback to the driver being probed when table and subtable match (and the optional callback is successful). The full combo, iykyk. 💖
• driver_data — sideband data provided back to the driver. Little side quest data, bestie. 🦋
