vmw_vkms_mo...lock_relaxed(9)

💅 vmw_vkms_modeset_lock_relaxed — like, the whole vibe ✨

okay so bestie, welcome to the Kernel API Manual 🎀 — this page is filed under vmw_vkms_mo...lock_relaxed(9) (yeah the name got truncated, the header did that, not me 💀) and it's all about one lil function that guards your crtc while a modeset is happening. she's lowkey the chill younger sibling of vmw_vkms_modeset_lock. let's get into it 🫶

---

🌸 SYNOPSIS 🌸

bool vmw_vkms_modeset_lock_relaxed (struct drm_crtc *crtc );

that's it. that's the whole signature. she takes one thing and returns a bool, iconic behavior honestly 👑

---

🦋 ARGUMENTS 🦋

• crtc — the crtc you wanna lock for vkms. that's the whole assignment. protect the crtc, bestie 💖

---

✨ DESCRIPTION ✨

so here's the tea ☕ — this function is much like vmw_vkms_modeset_lock, with one big main-character difference: if the crtc is currently in a modeset, she will return immediately. like, no waiting, no blocking, no "hold on let me finish." she peeks, sees it's busy, and bounces 🏃‍♀️💨

the return value is true if it actually locked vkms to modeset, or false otherwise. simple as that. no cap 💯

ngl this is the "relaxed" one for a reason — if you were expecting her to wait her turn like the non-relaxed version, she is simply not doing that 🙈
