📦 version 7.3.1, in nixpkgs unstable

💖 xe_guc_buf_cache_init 💖

okay so this is a page from the Kernel API Manual, bestie — it's all about xe_guc_buf_cache_init, and honestly? it's giving "small function, big responsibility." let me spill ✨

🌸 NAME 🌸

xe_guc_buf_cache_init — literally just Initializes the GuC Buffer Cache. that's the whole vibe. 🎀

🦋 SYNOPSIS 🦋

int xe_guc_buf_cache_init (struct xe_guc_buf_cache *cache );

yes that's the whole signature. short king. 👑

💅 ARGUMENTS 💅

  • cache — the xe_guc_buf_cache you wanna initialize. that's it, that's the one (1) argument, and it's the star of the show 🫶

✨ DESCRIPTION ✨

so here's the tea ☕ — the Buffer Cache lets you obtain a reusable buffer 🔁 that you can use to pass data to GuC or read data from GuC, and the whole point is you don't need to create an ad-hoc allocation every single time. no cap, that's the entire flex. it's giving "why allocate fresh when you can reuse" energy 💀✨

think of it as the group chat of memory: everybody's already there, nobody's making a new chat for every single message 🙈

🔥 RETURN 🔥

  • 0 on success 🎉
  • a negative error code on failure 😭

that's it. success is a zero, failure is a sad little negative number. periodt 💜

👑 SEE ALSO 👑

the kernel file lives right here, bestie:

  • Kernel file ./drivers/gpu/drm/xe/xe_guc_buf.c

and here's the whole friend group — go say hi to all of them 🧚:

ok real talk: this page came out of ./drivers/gpu/drm/xe and the date stamp on it is October 2026 — so yeah, it's a little time traveler 🕰️✨

and that's the whole page, bestie!! slay, you now understand the GuC Buffer Cache init 💖🎀🦋🌸 mwah 💋
