ENUM IWL_DEBUG_CMDS(9)

🌸 NAME 🌸

enum iwl_debug_cmds — the debug commands, bestie 💅 and yes this is from the Kernel API Manual, like, the actual kernel, we're in the kernel rn 🫶

✨ SYNOPSIS ✨

okay so here's the whole enum, character for character, no cap:

enum iwl_debug_cmds {
    LMAC_RD_WR ,
    UMAC_RD_WR ,
    HOST_EVENT_CFG ,
    INVALID_WR_PTR_CMD ,
    DBGC_SUSPEND_RESUME ,
    BUFFER_ALLOCATION ,
    GET_TAS_STATUS ,
    FW_DUMP_COMPLETE_CMD ,
    FW_CLEAR_BUFFER ,
    MFU_ASSERT_DUMP_NTF

};

like, that's the entire vibe. ten constants. slay 🔥

💖 CONSTANTS 💖

okay now the main character energy — one bullet per constant, and I'm not skipping a single one 🎀

• LMAC_RD_WR — LMAC memory read/write, and it does it using struct iwl_dbg_mem_access_cmd and struct iwl_dbg_mem_access_rsp. two structs, one job ✨
• UMAC_RD_WR — same energy but for UMAC memory read/write, also using struct iwl_dbg_mem_access_cmd and struct iwl_dbg_mem_access_rsp 🦋
• HOST_EVENT_CFG — updates the enabled event severities, via struct iwl_dbg_host_event_cfg_cmd 👑
• INVALID_WR_PTR_CMD — the invalid write pointer, and it's set in the TFD when it's not in use. she's literally just sitting there marking "nobody home" 💀
• DBGC_SUSPEND_RESUME — DBGC suspend/resume command (the source spells it "commad" and honestly? iconic, we keep her 💅). Uses a single dword as data: 0 — resume DBGC recording, 1 — suspend DBGC recording. that's it, that's the whole dword 🌈
• BUFFER_ALLOCATION — passes DRAM buffers to a DBGC, via struct iwl_buf_alloc_cmd 🍓
• GET_TAS_STATUS — sends a command to fw to get TAS status, and the response is struct iwl_tas_status_resp — round trip bestie 😭
• FW_DUMP_COMPLETE_CMD — sends a command to fw once dump collection is completed, via struct iwl_dbg_dump_complete_cmd ✅
• FW_CLEAR_BUFFER — clears the firmware's internal buffer, and no payload. zero. nothing. empty. she said "no thoughts" 🧚
• MFU_ASSERT_DUMP_NTF — struct iwl_mfu_assert_dump_notif, that's the one 🎀
