STRUCT L3_FLAGMUX_DATA(9)

💅 struct l3_flagmux_data(9) — Flag Mux information

okay bestie, so this is a Kernel API Manual page and today's main character is struct l3_flagmux_data — literally just the Flag Mux information. that's the whole vibe. ✨

🎀 SYNOPSIS 🎀

here's the whole struct, exactly as it lives, no cap:

struct l3_flagmux_data {
    u32 offset;
    struct l3_target_data *l3_targ;
    u8 num_targ_data;
    u32 mask_app_bits;
    u32 mask_dbg_bits;
 };

🦋 Members 🦋

• offset — how far you gotta scoot from base to reach the flagmux register. it's giving "starting coordinates" energy 💫
• l3_targ — an array indexed by the flagmux index (that's the bit offset, iykyk) and each slot points at the target data. the ones that just don't get support are marked with L3_TARGET_NOT_SUPPORTED — not everyone gets an invite to the party 🙈
• num_targ_data — literally the number of entries in the target data. the headcount. the guest list length 🎀
• mask_app_bits — ignore these bits from the raw application irq status. we do not perceive them. we do not see them. 💅
• mask_dbg_bits — same deal but for the raw debug irq status. also ignored, also unperceived. 🫶

go read those, they're the friend group 👑

okay that's the whole page, slay 🦋 this little icon came from the ./drivers/bus directory, dated October 2026, and the man page goes by struct l3_flagmux_data(9) — mwah, periodt 💖🎀
