STRUCT HBM_DMA_SETUP_RESPONSE(9)

💅 NAME 💅

ok so bestie, welcome to the Kernel API Manual — yes, THE Kernel API Manual, we're literally in the big leagues now ✨ — and this page is all about struct hbm_dma_setup_response, which is, you guessed it, the dma setup response 🎀 that's it, that's the whole name, slay.

🌸 SYNOPSIS 🌸

like, here's the whole struct, copied exactly, no notes, no edits, we respect the source fr fr 👑

struct hbm_dma_setup_response {
    u8 hbm_cmd;
    u8 status;
    u8 reserved[2];
 };

🦋 Members 🦋

okay so let's meet the cast of this little struct, they're all main characters in their own way 🫶

• hbm_cmd — the bus message command header 🚌 like the little ID badge so everyone knows what message they're looking at.
• status — it's giving success-or-fail energy: 0 on success; otherwise DMA setup failed 😭💀 so basically if this isn't 0, things did NOT go well.
• reserved — reserved for alignment 🧚 just vibing there, padding things out so everything lines up cute. Don't touch, it's reserved, iykyk.
