🌸 drm_mode_vrefresh(9) 🌸

ok so this is a page straight out of the Kernel API Manual and honestly bestie, it's a little one but it's a vibe 💅 it lives in ./drivers/gpu/drm/drm_modes.c and it does exactly one thing, but it does it flawlessly.

✨ NAME ✨

drm_mode_vrefresh — get the vrefresh of a mode 🖥️✨

like. that's it. that's the whole job. and she ate.

🎀 SYNOPSIS 🎀

int drm_mode_vrefresh (const struct drm_display_mode *mode );

one function, one argument, returns an int. no cap, that's the whole signature 🔥

🦋 ARGUMENTS 🦋

  • mode — a mode. yes, that's the description. the mode. the mode. the one you're passing in. lowkey iconic that they didn't elaborate 🫶

👑 RETURN 👑

returns the mode's vrefresh rate in Hz, rounded to the nearest integer 🌈

so like — no decimals, no "roughly", no "about", she's giving you a whole number and she's giving it precisely. round round round, nearest integer, periodt ⭐

💜 SEE ALSO 💜

ok bestie buckle up, this is the long part, but every single one of these matters, so no skipping 🙈 this is the whole drm modes friend group and they're all linked, so here's the full roll call, exactly as it goes:

and the kernel file she actually lives in:

./drivers/gpu/drm/drm_modes.c
💀 real talk though: the whole see-also list is basically the entire mode-handling squad, so if you're poking at drm_mode_vrefresh you're probably gonna meet at least a few of them. iykyk.

that's the page!! short, sweet, does exactly what it says on the tin 🍓
