STRUCT ATH12K_REG_TPC_POWER_INFO(9)

💖 struct ath12k_reg_tpc_power_info(9) 💖

okay bestie, welcome to the Kernel API Manual ✨ — today's main character is struct ath12k_reg_tpc_power_info, aka the regulatory TPC power info struct. she's lowkey just a little bundle of power numbers and we're gonna learn her whole vibe. no cap.

---

🌸 NAME 🌸

struct ath12k_reg_tpc_power_info — regulatory TPC power info 🫶

---

✨ SYNOPSIS ✨

like, here's literally her whole shape. don't touch a single character, she's perfect:

struct ath12k_reg_tpc_power_info {
    bool is_psd_power;
    u8 eirp_power;
    enum wmi_reg_6g_ap_type ap_power_type;
    u8 num_pwr_levels;
    u8 reg_max[ATH12K_NUM_PWR_LEVELS];
    u8 ap_constraint_power;
    s8 tpe[ATH12K_NUM_PWR_LEVELS];
    struct ath12k_chan_power_info
chan_power_info[ATH12K_NUM_PWR_LEVELS];
 };

🎀 Members 🎀

it's giving roster reveal, so let's meet the whole squad 💅

• is_psd_power — the vibe check: is this PSD power or not? bool, so it's a yes/no girlie.
• eirp_power — maximum EIRP power, in dBm. ⚠️ careful bestie: this one's valid only if power is PSD. otherwise she's just sitting there being decorative.
• ap_power_type — the type of power, an enum wmi_reg_6g_ap_type. the options are SP / LPI / VLP. pick your fighter 🥊
• num_pwr_levels — the number of power levels. literally just a count, but an important one ✨
• reg_max — an array of maximum TX power (dBm) per PSD value. size: ATH12K_NUM_PWR_LEVELS. iconic.
• ap_constraint_power — AP constraint power, in dBm. 🌈
• tpe — the TPE values processed from the TPE IE. signed bytes (s8), one per level, ATH12K_NUM_PWR_LEVELS of them.
• chan_power_info — the power info to send to firmware 📨 (it's a struct ath12k_chan_power_info, arrayed out to ATH12K_NUM_PWR_LEVELS).

• struct ath12k_chan_power_info(9) — her bestie, obviously 🫶

💀 friendly reminder that eirp_power is only valid when the power is PSD. don't be out here reading it in the wrong context, bestie, that's not the move.

and that's the whole page, bestie!! 🎀 this lil icon came from the Kernel file ./drivers/net/wireless/ath/ath12k and she's dated October 2026 — periodt. go slay some regulatory power configs 💅✨🌸
