STRUCT IWL_DBG_MEM_ACCESS_CMD(9)

💖 NAME 💖

struct iwl_dbg_mem_access_cmd — the little struct that literally asks the device to read or write memory 🫶 (this is a page from the Kernel API Manual, bestie, so buckle up)

✨ SYNOPSIS ✨

struct iwl_dbg_mem_access_cmd {
    __le32 op;
    __le32 addr;
    __le32 len;
    __le32 data[];
 };

okay so that trailing data[] is a flexible array member and yes she IS the main character of this struct, we'll get to her 💅

🌸 Members 🌸

• op — the operation, and it's one of the DEBUG_MEM_OP_* values 🎀
• addr — the address you're reading from or writing to, iykyk
• len — how much to read or write, and bestie this is counted in dwords, not bytes, so don't come for me with byte math 😭
• data — for write operations this holds the source buffer 💖 (read-only ops, she just vibes)

🦋 SEE ALSO 🦋

no cap, this struct has a whole friend group and they're all listed in the kernel file ./drivers/net/wireless/intel/iwlwifi/fw/api/debug.h 🌈
