xxxfb_sync(9)

💖 NAME 💖

okay so this is xxxfb_sync(9), straight from the Kernel API Manual — and bestie, listen: this one is NOT a required function. Normally the accel engine for a graphics card takes a specific amount of time. A lot of the time we have to wait for the accelerator to finish its operation before we can write to the framebuffer, so we can have consistent display output. That’s the whole vibe. ✨

✨ SYNOPSIS ✨

int xxxfb_sync (struct fb_info *info );

🎀 ARGUMENTS 🎀

• info — frame buffer structure that represents a single frame buffer. It’s giving “the main character struct” tbh. 🫶

💅 DESCRIPTION 💅

If the driver has implemented its own hardware-based drawing function, implementing this function is highly recommended. Like, do it, bestie — it’s literally recommended. 👑

yes, xxxfb_suspend(9) and xxxfb_resume(9) show up twice at the end — that’s exactly what the original says, so we keep it. no erasing the duplicate references, periodt. 💀

okay that’s the page, bestie 💖 the footer says source path ./drivers/video/fbdev, dated October 2026, and the manual label is xxxfb_sync(9) — so you already know it’s official, slay 🌈✨
