DRM_CAP_DUMB...FERRED_DEPTH(9)

✨ NAME ✨

DRM_CAP_DUMB_PREFERRED_DEPTH — bestie, that's literally the whole name, no little dash-summary after it, she's mysterious like that 💅

🎀 SYNOPSIS 🎀

DRM_CAP_DUMB_PREFERRED_DEPTH

🦋 DESCRIPTION 🦋

Okay so this one's the preferred bit depth for dumb buffers ✨ That's it, that's the whole vibe.

Now let's talk bit depth, because the way people mix this up is wild 😭 The bit depth is the number of bits used to indicate the color of a single pixel, excluding any padding. And that is a totally different thing from the number of bits per pixel, no cap. For instance, XRGB8888 has a bit depth of 24 but has 32 bits per pixel. See? Same pixel, different number. Do not confuse them, bestie, I'm begging 🙈

Small but important: this preference only applies to dumb buffers. For other types of buffers it's irrelevant — like, genuinely doesn't matter at all 💀
