💅 vmw_validation_prepare(9) — a Kernel API Manual moment 🎀

okay so bestie, welcome to the Kernel API Manual page for vmw_validation_prepare(9) — it's giving "let's get this validation context ready" and honestly? iconic. 🦋

✨ NAME ✨

vmw_validation_prepare — get a validation context all prepped and cute for command submission 💖

🌸 SYNOPSIS 🌸

int vmw_validation_prepare (struct vmw_validation_context *ctx , struct
mutex *mutex , bool intr );

like, that's the whole vibe. three little args and it does the thing, no cap.

🎀 ARGUMENTS 🎀

  • ctx — the validation context itself, aka the main character ✨
  • mutex — the mutex that's out here protecting resource reservation 🫶
  • intr — a bool that says whether we should do our waits interruptible if possible. yes bestie, if possible 🙈

💜 DESCRIPTION 💜

okay so real talk: the way there's just one single reservation mutex called mutex? lowkey an unfortunate construct, ngl. the manpage itself is like "ideally resource reservation should be moved to per-resource ww_mutexes" — so that's the dream, that's the goal, that's the future 🌈.

and here's the important bit, so listen up 💀: if this function doesn't return Zero to indicate success, then all the resources are left unreserved but still referenced. like they're free but also not free. so pay attention to that return value, fr fr 🙏

⭐ RETURN ⭐

  • Zero on success — slay 💅
  • -ERESTARTSYS if it got interrupted 😭
  • negative error code on error — the classic "something went sideways" energy 💀

🧚 SEE ALSO 🧚

the kernel file ./drivers/gpu/drm/vmwgfx/vmwgfx_validation.c and literally the whole friend group:

like, the whole squad showed up. obsessed 👑

🫶 reminder: one mutex for everything is unfortunate (their word, not mine) and a failed prepare leaves resources unreserved-but-referenced. read the return value. i'm begging 🙈

and that's the page!! brought to you by ./drivers/gpu/drm/vmwgfx, dated October 2026, in the Kernel API Manual — mwah, go prepare those contexts bestie 💖✨🎀
