xe_lrc_create(9)

xe_lrc_create(9) 💖

okay so this one is from the Kernel API Manual, and it's literally all about making a brand-new LRC. bestie, we are so back. 🫶

---

✨ NAME ✨

xe_lrc_create — Create a LRC. that's it, that's the vibe. 💅

---

🌸 SYNOPSIS 🌸

struct xe_lrc * xe_lrc_create (struct xe_hw_engine *hwe , struct xe_vm *vm , void *replay_state , u32 ring_size , u16 msix_vec , u32 flags );

---

🎀 ARGUMENTS 🎀

• hwe — the Hardware Engine. the engine in question, no cap. 🔥
• vm — the VM (address space). literally the address space vibe. 🦋
• replay_state — GPU hang replay state. yes bestie, hang replay state. 😭
• ring_size — LRC ring size. the size of the ring, periodt. 🎀
• msix_vec — MSI-X interrupt vector (for platforms that support it). 💖
• flags — LRC initialization flags. flags for initializing the LRC. 🌸

---

💅 DESCRIPTION 💅

Allocate and initialize the Logical Ring Context (LRC). that's the whole assignment, and it ate. ✨

Return pointer to created LRC upon success and an error pointer upon failure. so: success = pointer to the created LRC, failure = error pointer. iconic either way. 💜
