STRUCT IWL_BT_COEX_PROFILE_NOTIF(9)

💖 struct iwl_bt_coex_profile_notif — a Kernel API Manual moment 💖

okay bestie, so this is a page from the Kernel API Manual, and today's main character is struct iwl_bt_coex_profile_notif. it's giving "tiny struct, big responsibilities" ngl.

✨ NAME ✨

struct iwl_bt_coex_profile_notif — the notification all about BT coex 🦋 (yes, that's Bluetooth coexistence, we're being chic and abbreviating)

🌸 SYNOPSIS 🌸

struct iwl_bt_coex_profile_notif {
    u8 wifi_loss_low_rssi[COEX_NUM_BAND][COEX_NUM_CHAINS];
    u8 wifi_loss_mid_high_rssi[COEX_NUM_BAND][COEX_NUM_CHAINS];
};

like, that's the whole thing. two 2D arrays, u8 flavored, and they are so ready to tell you how much WiFi you're about to lose. 😭

👑 Members 👑

• wifi_loss_low_rssi — this one's the predicted lost WiFi rate (% of air time that BT is utilizing) when the RSSI is low (<= -65 dBm). lowkey tragic numbers but at least you know them in advance 💀
• wifi_loss_mid_high_rssi — same predicted lost WiFi rate vibe (% of air time that BT is utilizing), except this time the RSSI is mid/high (>= -65 dBm). highkey the better timeline, but BT is still out here eating your air time 🫶

not me pointing out that both arrays are declared as [COEX_NUM_BAND][COEX_NUM_CHAINS] — that's the shape bestie, per-band and per-chain, periodt. ⭐

🌈 and that's the whole page, bestie! this little legend came out of ./drivers/net/wireless/intel/i... and the doc fairies dated it October 2026, filed under the manual name Kernel API Manual, with the page title struct iwl_b...rofile_notif(9). slay, go read the coex header, mwah 💅💜
