STRUCT ATH_HW_PRIVATE_OPS(9)

💖 NAME 💖

struct ath_hw_private_ops — callbacks used internally by hardware code.

Bestie, welcome to the struct ath_hw_private_ops(9) page from the Kernel API Manual. This is the private callback club, and it is very much invite-only. 💅

✨ SYNOPSIS ✨

okay so here's the whole struct — every single pointer, exactly as written, no cap:

       struct ath_hw_private_ops {
           void (*init_hang_checks)(struct ath_hw *ah);
           bool (*detect_mac_hang)(struct ath_hw *ah);
           bool (*detect_bb_hang)(struct ath_hw *ah);
           void (*init_cal_settings)(struct ath_hw *ah);
           bool (*init_cal)(struct ath_hw *ah, struct ath9k_channel *chan);
           void (*init_mode_gain_regs)(struct ath_hw *ah);
           void (*setup_calibration)(struct ath_hw *ah, struct ath9k_cal_list
       *currCal);
           int (*rf_set_freq)(struct ath_hw *ah, struct ath9k_channel *chan);
           void (*spur_mitigate_freq)(struct ath_hw *ah, struct ath9k_channel
       *chan);
           bool (*set_rf_regs)(struct ath_hw *ah, struct ath9k_channel *chan,
       u16 modesIndex);
           void (*set_channel_regs)(struct ath_hw *ah, struct ath9k_channel
       *chan);
           void (*init_bb)(struct ath_hw *ah, struct ath9k_channel *chan);
           int (*process_ini)(struct ath_hw *ah, struct ath9k_channel *chan);
           void (*olc_init)(struct ath_hw *ah);
           void (*set_rfmode)(struct ath_hw *ah, struct ath9k_channel *chan);
           void (*mark_phy_inactive)(struct ath_hw *ah);
           void (*set_delta_slope)(struct ath_hw *ah, struct ath9k_channel
       *chan);
           bool (*rfbus_req)(struct ath_hw *ah);
           void (*rfbus_done)(struct ath_hw *ah);
           void (*restore_chainmask)(struct ath_hw *ah);
           u32 (*compute_pll_control)(struct ath_hw *ah, struct ath9k_channel
       *chan);
           bool (*ani_control)(struct ath_hw *ah, enum ath9k_ani_cmd cmd, int
       param);
           void (*do_getnf)(struct ath_hw *ah, int16_t
       nfarray[NUM_NF_READINGS]);
           void (*set_radar_params)(struct ath_hw *ah, struct ath_hw_radar_conf
       *conf);
           int (*fast_chan_change)(struct ath_hw *ah, struct ath9k_channel
       *chan, u8 *ini_reloaded);
           void (*ani_cache_ini_regs)(struct ath_hw *ah);
         #ifdef CONFIG_ATH9K_BTCOEX_SUPPORT;
           bool (*is_aic_enabled)(struct ath_hw *ah);
         #endif ;
        };

🫶 Members 🫶

• init_cal_settings — setup types of calibrations supported.
• init_cal — starts actual calibration.
• init_mode_gain_regs — Initialize TX/RX gain registers.
• setup_calibration — set up calibration.
• rf_set_freq — change frequency.
• spur_mitigate_freq — spur mitigation.
• set_rf_regs — the manpage gives no description here, so we're not inventing one, bestie 🙈.
• compute_pll_control — compute the PLL control value to use for AR_RTC_PLL_CONTROL for a given channel.
• ani_cache_ini_regs — cache the values for ANI from the initial register settings through the register initialization.

🌸 Description 🌸

This structure contains private callbacks designed to only be used internally by the hardware core. Translation: it's giving internal-only energy — hardware core business, not for random outside code to touch. 🔥
