ENUM IWL_FW_ERROR_DUMP_TYPE(9)

💾 enum iwl_fw_error_dump_type(9) 🎀

okay so bestie, welcome to the Kernel API Manual page for enum iwl_fw_error_dump_type(9) — it's giving very much "backstage pass to the crash dump" energy and honestly? iconic. this is the enum that tells you what kind of thing each chunk of an Intel iwlwifi firmware error dump actually is. every section of the dump file is labeled with one of these. let's get into it 💅

✨ NAME ✨

enum iwl_fw_error_dump_type — types of data in the dump file 🗂️✨

};

🦋 CONSTANTS 🦋

seventeen constants, no skips, we're doing the whole roster 💖

• IWL_FW_ERROR_DUMP_CSR — Control Status Registers, and we're grabbing them from offset 0 🎯
• IWL_FW_ERROR_DUMP_RXF — the RX FIFO contents, like, the whole vibe of what came in 📥
• IWL_FW_ERROR_DUMP_TXCMD — the last TX command data, structured as struct iwl_fw_error_dump_txcmd packets 📤
• IWL_FW_ERROR_DUMP_DEV_FW_INFO — struct iwl_fw_error_dump_info, the info on the device / firmware 🧠
• IWL_FW_ERROR_DUMP_FW_MONITOR — firmware monitor, main character of the monitoring world 👀
• IWL_FW_ERROR_DUMP_PRPH — a range of periphery registers, and heads up bestie: there can be several sections like this in a single file 🌀
• IWL_FW_ERROR_DUMP_TXF — the TX FIFO contents, outbox-core 📬
• IWL_FW_ERROR_DUMP_FH_REGS — a range of FH registers 🧮
• IWL_FW_ERROR_DUMP_MEM — a chunk of memory, literally just a lil slice of the good stuff 🍰
• IWL_FW_ERROR_DUMP_ERROR_INFO — the description of what triggered this dump. structured as struct iwl_fw_error_dump_trigger_desc. so like, this is the "who did this" field 💀
• IWL_FW_ERROR_DUMP_RB — the content of an RB, structured as struct iwl_fw_error_dump_rb 🔁
• IWL_FW_ERROR_DUMP_PAGING — UMAC's image memory segments which were paged to the DRAM 📚
• IWL_FW_ERROR_DUMP_RADIO_REG — dump the radio registers 📻✨
• IWL_FW_ERROR_DUMP_INTERNAL_TXF — internal TX FIFO data 🗃️
• IWL_FW_ERROR_DUMP_EXTERNAL — used only by external code utilities, and for that reason it's not in use in any other place in the Linux Wi-Fi stack 🚫 (so don't come for it, it's just off doing its own thing)
• IWL_FW_ERROR_DUMP_MEM_CFG — the addresses and sizes of fifos in the smem, which we get from the fw after ALIVE. the content is structured as struct iwl_fw_error_dump_smem_cfg 🧾
• IWL_FW_ERROR_DUMP_D3_DEBUG_DATA — D3 debug data 😴🔍
