ENUM IWL_SAP_RADIO_STATE_BITMAP(9)

💖 enum iwl_sap_radio_state_bitmap 💖

okay bestie, real talk — this page is from the Kernel API Manual, and it's about one tiny enum that tells you whether the radio is even allowed to be on. it's giving "two bits decide everything" energy and honestly? iconic. let's get into it 🫶

---

✨ NAME ✨

enum iwl_sap_radio_state_bitmap — used for %SAP_MSG_NOTIF_RADIO_STATE

like literally that's its whole job: it's the bitmap that shows up in %SAP_MSG_NOTIF_RADIO_STATE. no cap. 💅

---

🎀 SYNOPSIS 🎀

enum iwl_sap_radio_state_bitmap {
    SAP_SW_RFKILL_DEASSERTED ,
    SAP_HW_RFKILL_DEASSERTED

};

look at it. two members. zero drama. the trailing comma before the blank line and the stray }; are exactly how the original rolls, so don't come for me about formatting 😭

---

🌸 Constants 🌸

• SAP_SW_RFKILL_DEASSERTED — if this bit is set, the SW RfKill is de-asserted 💖 (translation: software isn't holding the radio hostage anymore)
• SAP_HW_RFKILL_DEASSERTED — if this bit is set, the HW RfKill is de-asserted ✨ (the hardware switch also said "you're free")

---

🦋 Description 🦋

so here's the whole vibe check: if both bits are set, then the radio is on. 🔥

that's it. that's the description. software rfkill de-asserted plus hardware rfkill de-asserted = radio go brrr. both. not one. both. the way that AND-logic just ate, honestly 👑
