STRUCT IWL_POWERTABLE_CMD(9)

💅 struct iwl_powertable_cmd(9)

okay bestie, buckle up — we're in the Kernel API Manual today and this one is literally the legacy power command 🫶. Beside old API support, this is used also with a new power API for device wide power settings. also she has a command id: POWER_TABLE_CMD = 0x77 (command, has simple generic response) ✨

✨ SYNOPSIS ✨

like, here's the whole struct, exactly, no cap:

struct iwl_powertable_cmd {
    __le16 flags;
    u8 keep_alive_seconds;
    u8 debug_flags;
    __le32 rx_data_timeout;
    __le32 tx_data_timeout;
    __le32 sleep_interval[IWL_POWER_VEC_SIZE];
    __le32 skip_dtim_periods;
    __le32 lprx_rssi_threshold;
 };

🎀 Members 🎀

• flags — power table command flags, and they come from POWER_FLAGS_* 👑 that's the whole vibe.
• keep_alive_seconds — keep alive period in seconds, fr fr. default is 25 sec. minimum allowed is 3 * DTIM. and listen — keep alive period must be set regardless of power scheme or current power state, no exceptions 💀. also FW use this value also when PM is disabled, so yeah she matters.
• debug_flags — debug flags. that's it. that's the whole description 🙈
• rx_data_timeout — minimum time (usec) from last Rx packet for AM to PSM transition — legacy PM 🦋
• tx_data_timeout — minimum time (usec) from last Tx packet for AM to PSM transition — legacy PM 🌸 (yes twin, same energy as the rx one, just the other direction)
• sleep_interval — not in use. she's just sitting there, iconic but unemployed 💅
• skip_dtim_periods — number of DTIM periods to skip if Skip over DTIM flag is set. example time: if it is required to skip over one DTIM, this value need to be set to 2 (DTIM periods) ⭐ like yes, 2, not 1, don't come for me.
• lprx_rssi_threshold — signal strength up to which LP RX can be enabled. Default: 80dbm 🔥
