💅 amdgpu_dm_connector_poll(9) — like, the Kernel API Manual page you didn't know you needed

okay so bestie, this is a page straight out of the Kernel API Manual, and it's genuinely about poking at a display connector to see if anything's plugged in 🫶. sit down, grab a strawberry 🍓, and let's get into it.

✨ NAME ✨

amdgpu_dm_connector_poll — literally the function whose whole personality is polling a connector to see if it's connected to a display 👀💖

🦋 SYNOPSIS 🦋

enum drm_connector_status amdgpu_dm_connector_poll (struct
amdgpu_dm_connector *aconnector , bool force );

🌸 ARGUMENTS 🌸

• aconnector — the DM connector you're polling, bestie. it owns base drm_connector and dc_link, like a main character with two iconic sidekicks 👑
• force — if it's true, you're forcing polling even when DAC load detection was used. so like, no shortcuts, we're doing the whole thing 💅

💜 DESCRIPTION 💜

so here's the vibe: this one's for connectors that don't support HPD (hotplug detection), and its job is to periodically check whether the connector is connected to a display 🔥. no cap, that's the whole plot.

and when the connection was determined via DAC load detection, we do not re-run it on normal polls — because that would cause visible glitches, and we are not about that life 😭. the exception? when force is set. then we go anyway, periodt.

⭐ RETURN ⭐

it hands you back the probed connector status — connected / disconnected / unknown 💀 (yes, "unknown" is a real option, we don't always know and that's valid 🧚).
