STRUCT IWL_FW_ERROR_DUMP_SMEM_CFG(9)

💖 struct iwl_fw_error_dump_smem_cfg(9) 💖

okay so bestie, welcome to the Kernel API Manual ✨ — this page is all about struct iwl_fw_error_dump_smem_cfg, which is literally the Dump SMEM configuration. and here's the tea 🍵: this bad boy must follow &struct iwl_fwrt_shared_mem_cfg — like, not optional, not a vibe, just the rules. no cap. 👑

🎀 SYNOPSIS 🎀

here's the whole struct, copy-paste perfect, don't touch a character:

struct iwl_fw_error_dump_smem_cfg {
    __le32 num_lmacs;
    __le32 num_txfifo_entries;
    struct {
      __le32 txfifo_size[TX_FIFO_MAX_NUM];
      __le32 rxfifo1_size;
    } lmac[MAX_NUM_LMAC];
    __le32 rxfifo2_size;
    __le32 internal_txfifo_addr;
    __le32 internal_txfifo_size[TX_FIFO_INTERNAL_MAX_NUM];
};

she's giving structured data realness 💅 and yes those are __le32 fields, we respect the endianness in this house 🫶

🌸 Members 🌸

• num_lmacs — literally the number of lmacs. that's it, that's the field 🦋
• num_txfifo_entries — the number of tx fifos. counting queen 👑
• lmac — the sizes of the lmacs' txfifos and rxfifo1. it's an array capped at MAX_NUM_LMAC, and inside each one lives txfifo_size[TX_FIFO_MAX_NUM] and rxfifo1_size. nested struct moment ✨
• rxfifo2_size — the size of rxfifo2. iconic, singular, no notes 💜
• internal_txfifo_addr — the address of the internal tx fifo. it knows where things live 📍
• internal_txfifo_size — the size of the internal tx fifo, and it's an array of TX_FIFO_INTERNAL_MAX_NUM entries. so many sizes 😭

ok that's the whole page, you ate that 💀 no skipping, every field accounted for.

and that's a wrap, bestie 🎀 this came straight out of ./drivers/net/wireless/intel/i..., dated October 2026, and the page itself is struct iwl_...ump_smem_cfg(9) — mwah, go read the real header now 💖🌈
