💅 xe_lrc_upda...with_address(9) 💅

okay so bestie, welcome to the Kernel API Manual ✨ — yes it's a real manual, yes it's about the kernel, no you cannot skip it, sit down and let me tell you about this little function 🫶

---

🌸 NAME 🌸

xe_lrc_update_hwctx_regs_with_address — it re-computes GGTT references inside a given LRC. that's the whole vibe. GGTT refs get recalculated, LRC is the container, slay 💅

---

✨ SYNOPSIS ✨

void xe_lrc_update_hwctx_regs_with_address (struct xe_lrc *lrc );

like literally that's it, one function, one argument, returns nothing (void), takes a pointer to a struct xe_lrc. no cap. 🎀

---

🦋 ARGUMENTS 🦋

• lrc — the struct xe_lrc instance. that's the one. the only one. the main character of this whole operation 👑

---

🎀 SEE ALSO 🎀

heads up bestie — the title up there is truncated in the manpage header (xe_lrc_upda...with_address(9)), that's just how the page name gets squished, not a typo, don't come for me 🙈

---

okay that's the whole page, go forth and compute your GGTT references 😌✨

💜 xoxo, your local kernel girly 💜
