okay time for the member-by-member vibe check, iykyk 🔥

• pool — the pool this command belongs to. it's giving "found family" fr fr 🫶
• free — entry in the pool of free commands list. lowkey just her little spot in the lineup ✨
• opcode — the command type opcode. this is the main character identifier 👑
• flags — flags used by the command. little bool-ish accessories, we love a detail 💅
• cmds — array of command bodies for this extended cmd. she's got layers, literally 🌸
• num_cmds — quantity of commands in cmds array. yes bestie, we're counting 🍓
• cmd_dma — DMA address of the command body. hardware needs to find her too 😭
• data — memory allocation for command-specific data. her personal storage era 🎀
• data_dma — DMA address for command-specific data. same data, but now with a hardware-visible address ⭐

💀 reminder bestie: this page is pure reference. no invented behaviour, no extra lore. just the struct, her members, and the header file. periodt.

and that's the whole page, mwah 😭💖 sign-off time: this came from the source listed as ./drivers/media/platform/renes... (yes, it's the one above, just truncated in the footer), dated October 2026, and it's serving struct vsp1_dl_ext_cmd(9) energy from start to finish. slay, bye 🧚✨
