xe_lrc_set_...eue_priority(9)

💅 xe_lrc_set_multi_queue_priority(9) 💅

okay so bestie, welcome to the Kernel API Manual — yes that's the whole manual name, don't @ me — and today we're learning about exactly one (1) little function that lives in the kernel and does one job and does it slayfully. it's xe_lrc_set_multi_queue_priority(9). say it with me. iconic.

---

✨ NAME ✨

xe_lrc_set_multi_queue_priority — literally just sets the multi queue priority in the LRC 🎀 no cap, that's the whole vibe.

---

🌸 SYNOPSIS 🌸

void xe_lrc_set_multi_queue_priority (struct xe_lrc *lrc , enum
xe_multi_queue_priority priority );

she returns nothing (void, we love a low-commitment queen) and she takes two things. that's it. that's the whole signature. periodt.

---

🦋 ARGUMENTS 🦋

• lrc — the Logical Ring Context 💫 your main character struct, the one getting her priority updated.
• priority — the multi queue priority of the exec queue 👑 aka the value we're about to translate into LRC-speak.

---

🔥 DESCRIPTION 🔥

so here's the tea ☕ this function takes that priority you handed her, converts it into the LRC multi queue priority format, and then updates the lrc descriptor with it. that's the move. convert → update. the way that she just does the thing without drama, we stan 💅

no extra steps, no surprises, no plot twists. she converts, she writes, she leaves. main character energy fr fr.
