STRUCT IWL_HW_PARAMS(9)

💖 struct iwl_hw_params(9) 💖

okay bestie, welcome to the Kernel API Manual page for struct iwl_hw_params — yes the whole manual name is literally "Kernel API Manual", we're in the kernel section now, it's giving ✨serious✨ but we're still gonna have fun.

---

🌸 NAME 🌸

struct iwl_hw_params — HW parameters. that's it, that's the whole description. hardware params, babes. 🫶

---

🎀 SYNOPSIS 🎀

here's the struct, exactly as written, no edits, no cap:

struct iwl_hw_params {
    u8 tx_chains_num;
    u8 rx_chains_num;
    bool use_rts_for_aggregation;
    u32 ct_kill_threshold;
    u32 ct_kill_exit_threshold;
    const struct iwl_sensitivity_ranges *sens;
 };

---

⭐ Members ⭐

okay field-by-field, let's go 💅

• tx_chains_num — the number of TX chains. that many transmit chains, periodt.
• rx_chains_num — the number of RX chains. same energy, receive side.
• use_rts_for_aggregation — whether you use rts/cts protection for HT traffic.
• ct_kill_threshold — the temperature threshold — and bestie, careful: it's in a hw dependent unit, so don't assume plain old degrees. 🙈
• ct_kill_exit_threshold — when to reeable the device — also in a hw dependent unit. relevant for 1000, 6000 and up. and yeah, struct iwl_sensitivity_ranges: range of sensitivity values. 🔥
• sens — sensitivity ranges pointer. a pointer. to the ranges. of sensitivity. iconic. 👑

🦋 Description 🦋

short and sweet and honestly kind of mysterious: it holds the module parameters. that's the whole vibe check. 💀

🌈 SEE ALSO 🌈

go look at these if you're nosy, i love that for you:

Kernel file ./drivers/net/wireless/intel/iwlwifi/dvm/dev.h enum iwl_agg_state(9), struct iwl_ht_agg(9), struct iwl_tid_data(9), struct iwl_dvm_bt_params(9), struct iwl_dvm_cfg(9)

ngl the see-also list is a whole little friend group of iwlwifi structs. read them together, iykyk. 🧚

and that's the page!! this masterpiece came out of ./drivers/net/wireless/intel/i... and it's stamped October 2026 — pop off, documentation, and see you next time for struct iwl_hw_params(9) again 💖🎀🦋
