mac_find_mode(9)

💅 mac_find_mode — find a video mode 💅

okay so we're deep in the kernel API manual and this page is mac_find_mode(9), bestie. it lives in the (9) section, aka the kernel API corner of the manual, and it's literally about hunting down a video mode. that's the whole vibe check. 🦋

---

✨ SYNOPSIS ✨

int mac_find_mode (struct fb_var_screeninfo *var , struct fb_info *info
, const char *mode_option , unsigned int default_bpp );

look at her. four args, one int return, no cap. 💅

---

🎀 ARGUMENTS 🎀

• var — the frame buffer user defined part of display. yeah that's the display bits you get to poke at 💖
• info — the frame buffer info structure. the main-character struct fr fr 👑
• mode_option — the video mode name (see mac_modedb[]). that's the name you're looking up, iykyk 🔥
• default_bpp — default color depth, in bits per pixel. the fallback color situation 🌈

---

🌸 DESCRIPTION 🌸

so the tea is this: it finds a suitable video mode. it tries to set the mode specified by mode_option. and if the name of the wanted mode begins with will fall back to the standard video mode database. (yeah the original sentence is a little unhinged, but that's literally what it says, so we're keeping it exactly like that 🙈 — no editing, no guessing, periodt.)

---

⭐ NOTE ⭐

the function is marked as __init and can only be used during system boot. like, boot-time only. not later. don't come for her after boot, she's literally gone 💀

returns the error code from fb_find_mode (see the fb_find_mode function). 🫶
