STRUCT XE_JOB_PTRS(9)

struct xe_job_ptrs(9) 🦋

okay so this page is from the Kernel API Manual, and it's literally all about struct xe_job_ptrs — the per hw engine instance data. No cap, that's the vibe 💅.

✨ NAME ✨

struct xe_job_ptrs — per hw engine instance data. Slay.

🌸 SYNOPSIS 🌸

struct xe_job_ptrs {
    struct dma_fence *lrc_fence;
    struct dma_fence_chain *chain_fence;
    u64 batch_addr;
    u32 head;
};

🎀 Members 🎀

bestie, the fence fields are pre-allocated and uninitialized — the manpage said it, not me. Don't get it twisted 💖

• lrc_fence — pre-allocated, uninitialized lrc fence. It's giving "allocated but not initialized yet," and that's exactly what the manpage says, periodt.
• chain_fence — pre-allocated, uninitialized fence chain node. Same energy: pre-allocated, uninitialized, waiting for its moment ✨.
• batch_addr — the batch buffer address. Short, sweet, iconic.
• head — the tail pointer of the LRC (so head pointer of job) when the job was submitted. Yes, both of those pointer mentions are in the sentence, don't @ me 😭.
