STRUCT IL_HW_PARAMS(9)

💖 struct il_hw_params(9) 💖

okay bestie, welcome to the Kernel API Manual page for struct il_hw_params — it's literally one struct and a whole lot of hardware-params energy. Buckle up, we're going in. 🎀

✨ NAME ✨

struct il_hw_params — the original NAME line is just struct il_hw_params - with nothing after the dash. Minimalist. Mysterious. No notes. 💅

🎀 SYNOPSIS 🎀

🫶 Members 🫶

• bcast_id — f/w broadcast station ID
• max_txq_num — Max # Tx queues supported
• dma_chnl_num — Number of Tx DMA/FIFO channels
• scd_bc_tbls_size — size of scheduler byte count tables
• tfd_size — TFD size
• tx_chains_num — Number of TX/RX chains
• rx_chains_num — Number of TX/RX chains
• valid_tx_ant — usable antennas
• valid_rx_ant — usable antennas
• max_rxq_size — Max # Rx frames in Rx queue (must be power-of-2)
• max_rxq_log — Log-base-2 of max_rxq_size
• rx_page_order — Rx buffer page order
• rx_wrt_ptr_reg — FH{39}_RSCSR_CHNL0_WPTR
• max_stations — no description in the original Members list; it's giving mystery 💅
• ht40_channel — is 40MHz width possible in band 2.4 BIT(NL80211_BAND_5GHZ) BIT(NL80211_BAND_5GHZ) — yes, the original repeats that BIT(NL80211_BAND_5GHZ) twice, and we respect the duplication 🫶
• max_beacon_itrvl — no description in the original Members list; mysterious main character field
• max_inst_size — no description in the original Members list; also mysterious
• max_data_size — no description in the original Members list; also mysterious

• ct_kill_threshold — temperature threshold
• beacon_time_tsf_bits — number of valid tsf bits for beacon time struct
• sens — il_sensitivity_ranges: range of sensitivity values
