link_detect_dac_load_detect(9)

💅 link_detect_dac_load_detect(9) — the Kernel API Manual, but make it cute 🎀

okay so bestie, welcome to the link_detect_dac_load_detect era of the Kernel API Manual. this one's short and sweet and lowkey a little chaotic (it makes your screen glitch, we'll get there) so let's just get into it ✨

---

🌸 NAME 🌸

link_detect_dac_load_detect — literally just performs DAC load detection. that's the whole vibe. no cap 💅

---

🦋 SYNOPSIS 🦋

bool link_detect_dac_load_detect (struct dc_link *link );

---

✨ ARGUMENTS ✨

• link — the DC link you wanna test, using the DAC load-detect path. that's the one, that's the girl 🫶

---

🧚 DESCRIPTION 🧚

so here's the tea: load detection is what you reach for when you need to detect the presence of an analog display and you can't read DDC. like, DDC said no, so we're doing it the other way 🙈

but — and this is important, bestie — this causes a visible visual glitch. visible. visual. glitch. the screen literally goes weird for a sec 😭 so it should be used sparingly. not every time, not for funsies, not "just to check" — sparingly. iykyk.

⚠️ warning bestie: visible visual glitch ahead. use it sparingly or the user will notice, fr fr 💀

---

👑 RETURN 👑

• true — if the VBIOS load-detect call reports OK 🔥
• false — otherwise 💀

that's it. binary queen behavior, periodt.

---

🌈 SEE ALSO 🌈

• Kernel file ./drivers/gpu/drm/amd/display/dc/link/link_detection.c — the source, the icon, the main character ✨
• link_detect_evaluate_edid_header(9)

• link_detect_connection_type_analog(9)

go read those too, they're like the friend group of this function 🫶🌸
