drm_dp_dsc_sink_bpp_incr(9)

💅 drm_dp_dsc_sink_bpp_incr 💅

okay so bestie, welcome to the Kernel API Manual, section 9 — yes we're in the kernel docs again, and yes this one is actually tiny and adorable. Buckle up 🎀

---

✨ NAME ✨

drm_dp_dsc_sink_bpp_incr — get bits per pixel increment. that's it. that's the whole job. she's a little one-function icon 👑

---

🌸 SYNOPSIS 🌸

u8 drm_dp_dsc_sink_bpp_incr (const u8 dsc_dpcd[DP_DSC_RECEIVER_CAP_SIZE]);

like, she takes exactly one thing and hands you back a u8. minimalism. we love to see it 🫶

---

🦋 ARGUMENTS 🦋

• dsc_dpcd — the DSC capabilities straight out of DPCD, bestie. that's the buffer you're feeding her: a const u8 dsc_dpcd[DP_DSC_RECEIVER_CAP_SIZE]. she does not want anything else, don't overcomplicate her life 💀

---

⭐ DESCRIPTION ⭐

so what does she do? she returns the bpp precision supported by the DP sink ✨ that's literally the whole description, no cap. you give her the sink's DSC capability blob, she tells you what bpp precision the sink can handle. short queen behavior, honestly 🌈

no hidden side quests here — this is a return-value situation, not a "mutates your struct" situation 🙈

💖 SEE ALSO 💖

bestie there are SO many siblings, she's part of a huge family (the dp helpers), and the man page wants you to know about all of them. no skipping, i promised. here we go, in order, exactly as listed 👑

like… ninety-ish functions. she has a big friend group, iykyk 💜
