STRUCT IWL_SHARED_MEM_LMAC_CFG(9)

💖 struct iwl_shared_mem_lmac_cfg 💖

okay so this is a page straight outta the Kernel API Manual — yes bestie, the kernel has a manual, and yes it's exactly as iconic as you'd hope 🎀

✨ NAME ✨

struct iwl_shared_mem_lmac_cfg — the LMAC shared memory configuration, no cap. it's the little struct that tells you where the LMAC's shared memory lives and how big the pieces are 🫶

🌸 SYNOPSIS 🌸

struct iwl_shared_mem_lmac_cfg {
    __le32 txfifo_addr;
    __le32 txfifo_size[TX_FIFO_MAX_NUM];
    __le32 rxfifo1_addr;
    __le32 rxfifo1_size;
 };

like... look at it. four fields. four. and every single one of them is doing its job 💅

🦋 Members 🦋

• txfifo_addr — the start addr of TXF0, and listen, it's excluding the context table 0.5KB so don't come for me when you're off by 0.5KB, that's literally in the spec 🙈
• txfifo_size — the size of the TX FIFOs. yes, plural, it's an array — TX_FIFO_MAX_NUM of them to be exact 💀
• rxfifo1_addr — the RXF1 addr. that's it. that's the field. main character energy, minimal words 🌟
• rxfifo1_size — the RXF1 size. pairs with the addr above, they're a package deal 💜
