💅 drm_dp_as_sdp_supported(9) — Kernel API Manual ✨

okay bestie, welcome to the drm_dp_as_sdp_supported(9) page, like literally the whole thing, and yes the manual name is right there in the title because we're thorough like that 💖

---

✨ NAME ✨

drm_dp_as_sdp_supported — check if adaptive sync sdp is supported 🦋

---

🌸 SYNOPSIS 🌸

bool drm_dp_as_sdp_supported (struct drm_dp_aux *aux , const u8
dpcd[DP_RECEIVER_CAP_SIZE] );

---

🎀 ARGUMENTS 🎀

• aux — the DisplayPort AUX channel, the lil' messenger doing the talking 👑
• dpcd — DisplayPort configuration data, aka the receiver's whole personality in bytes 🫶

---

💜 DESCRIPTION 💜

okay so this one is lowkey simple and honestly iconic for it: it returns true if adaptive sync sdp is supported, else it returns false. that's the whole vibe check, no cap 💅
