drm_fb_helper_set_par(9)

💅 drm_fb_helper_set_par(9) 💅

okay bestie, welcome to the Kernel API Manual — this one's a little function with main character energy in the fbdev world, and we're gonna get you acquainted. 🫶

---

✨ NAME ✨

drm_fb_helper_set_par — the actual implementation behind &fb_ops.fb_set_par, no cap 👑

---

🌸 SYNOPSIS 🌸

int drm_fb_helper_set_par (struct fb_info *info );

---

🎀 ARGUMENTS 🎀

• info — the fbdev that the helper registered, aka the whole reason this function has something to do 💖

---

🦋 DESCRIPTION 🦋

so here's the vibe: this lets fbcon do the mode init. literally that's its moment. ✨

it gets called at initialization time by the fbdev core when the driver is registering — like, the very first hello 👋 — and then again later on through the hotplug callback. so it shows up at the start and it comes back around whenever hotplug says so. consistent queen behavior, honestly. 🍓
