💖 radeon_get_s...d_nondp_ppll(9) 💖

ok so real talk, this is a page straight out of the Kernel API Manual and it is so niche and so specific and honestly? iconic for that. bestie we are going into the DRM/radeon mines together, grab my hand 🫶

✨ NAME ✨

radeon_get_shared_nondp_ppll — returns the PPLL that some other non-DP crtc is using, iykyk 💅

---

🎀 SYNOPSIS 🎀

int radeon_get_shared_nondp_ppll (struct drm_crtc *crtc );

like, that's the whole vibe. one function, one arg, it returns an int, periodt.

🦋 ARGUMENTS 🦋

• crtc — a drm crtc. yeah. that's the entire description the original gives us and honestly we're respecting it 💀 it's the crtc you're asking about, bestie.

🌸 DESCRIPTION 🌸

okay so here's the tea ☕ this function returns the PPLL (that's Pixel PLL, for the uninitiated 👑) that is being used by another non-DP crtc/encoder — and the whole point is that this one can be shared, i.e. it's running the same clock. shared clock energy fr fr ✨

so like… you're not making a new one, you're finding the one that's already out there living its best life on a different non-DP crtc and going "hey can we match?" 🎀
