msm_dp_displ...ost_phy_init(9)

💅 msm_dp_displ...ost_phy_init(9) — like, the Kernel API Manual page, bestie

okay so this is a page straight out of the Kernel API Manual, and the function is called msm_dp_display_host_phy_init. Say it with me. It's a mouthful, but she's iconic. ✨

---

🌸 NAME 🌸

msm_dp_display_host_phy_init — the girl who starts up the DP PHY 🎀

---

🦋 SYNOPSIS 🦋

bool msm_dp_display_host_phy_init (struct msm_dp_display_private *dp );

no cap, that's the whole vibe. she takes one pointer and hands you back a bool. 💅

---

🍓 ARGUMENTS 🍓

• dp — your main display data structure 🫶 like, the whole main-character data situation for the display. she needs it, she uses it, periodt.

---

⭐ DESCRIPTION ⭐

so what does she actually do? she prepares the DP PHY so that the AUX transactions can succeed. that's it, that's the job. 💖

think of it as getting the PHY ready backstage so the AUX transactions can walk out and slay on stage. no PHY prep, no AUX success — it's giving cause and effect, iykyk. 🌈

---

👑 RETURN 👑

• true — this call has initialized the PHY, bestie. she did that. 🔥
• false — the PHY was already set up beforehand, so this call didn't need to do the thing. 💀

not me noticing the original page spells it "initliazed" 🙈 — the facts are the facts, but the spelling is a whole mood. either way: true means freshly initialized by this call, false means somebody already got there first. 🧚

💜 SEE ALSO 💜

• Kernel file ./drivers/gpu/drm/msm/dp/dp_display.c — go read her source, fr fr
• msm_dp_display_mode_valid(9)
• msm_dp_bridge_detect(9)

and that's the page! 🎀 bye bestie, go init that PHY 💅

sign-off szn: this masterpiece lives at ./drivers/gpu/drm/msm/dp, dated October 2026, and the header still reads msm_dp_displ...ost_phy_init(9) (yes, she's truncated, and yes, she's still eating). 🦋✨
