xe_lrc_updat...with_address(9)

✨ NAME ✨

okay so bestie, this page is from the Kernel API Manual, and the page title is xe_lrc_updat...with_address(9) — yes, ellipsis and all, she's iconic. The actual function living here is xe_lrc_update_memirq_regs_with_address.

Her whole job: re-compute GGTT references in mem interrupt data for a given LRC. That's it, that's the assignment, no cap. Periodt. 💅

💅 SYNOPSIS 💅

Signature time, verbatim, no edits, fr fr:

void xe_lrc_update_memirq_regs_with_address (struct xe_lrc *lrc , struct
       xe_hw_engine *hwe , u32 *regs );

🎀 ARGUMENTS 🎀

• lrc — the xe_lrc struct instance. That's the LRC bestie in question. 💖
• hwe — the xe_hw_engine struct instance. The hw engine bestie. ✨
• regs — scratch buffer to be used as temporary storage. Lowkey just the temp stash. 🎀
