✨ vmw_guess_mode_timing ✨

okay so this is a page from the Kernel API Manual, and bestie, it's a tiny one but it's lowkey iconic 💅 it lives in the land of vmwgfx (that's the VMware graphics driver squad, iykyk) and it does exactly one thing: it makes up timing numbers for a 60Hz mode 🎀

🌸 NAME 🌸

vmw_guess_mode_timing — provides fake timings for a 60Hz vrefresh mode 🫶

like, not "fake" in a shady way!! it's just guessing the timings instead of you having to fill them in. main character energy tbh 👑

✨ SYNOPSIS ✨

void vmw_guess_mode_timing (struct drm_display_mode *mode );

that's it. one function, one argument, zero drama 🌈

🦋 ARGUMENTS 🦋

  • mode — a pointer to a struct drm_display_mode where you've already filled in the hdisplay and vdisplay members 💖 that's the whole vibe check here — if those two aren't set, this function has nothing to work with, so fill them in first, okay?? no cap 🙈

🎀 SEE ALSO 🎀

first up, the kernel file this thing actually lives in:

  • Kernel file ./drivers/gpu/drm/vmwgfx/vmwgfx_kms.c 📁

and then, bestie, the whole friend group 😭 the entire vmwgfx KMS/DU extended universe, all of it, in order:

thirty-one references, one little timing-guesser. the way that this function has more mutuals than it has lines of code 😭💀

ngl bestie, always check your mode pointer before you pass it — this page says it points to a struct drm_display_mode, and it does not say what happens if you hand it something else. respect the signature 🙏

and that's the whole page, short and sweet like a good group chat message 🍓 mwah 💋

sign-off time: this one came out of ./drivers/gpu/drm/vmwgfx, stamped October 2026 — put it in the scrapbook, it's a keeper 🧚‍♀️⭐💜
