✨ amdgpu_dm_dump_links_and_sinks ✨

okay so bestie, buckle up, because this is a kernel API manual page (the Kernel API Manual, no less 💅) and we're about to make it make sense. this function is literally called amdgpu_dm_dump_links_and_sinks and it's giving "debug dump of all DC links and their sinks." no cap. 🎀

🌸 NAME 🌸

amdgpu_dm_dump_links_and_sinks — debug dump of all DC links and their sinks. that's it, that's the vibe. ✨

---

🦋 SYNOPSIS 🦋

void amdgpu_dm_dump_links_and_sinks (struct amdgpu_device *adev );

like, it takes one argument and returns nothing. simple. iconic. periodt. 💅

---

💖 ARGUMENTS 💖

• adev — amdgpu device pointer. yes bestie, it's a pointer to the amdgpu_device. that's the whole argument. we love a low-maintenance function. 🫶

---

🌈 DESCRIPTION 🌈

so what does it actually do? it iterates through all DC links — every single one — and dumps information about local and remote (MST) sinks. think of it as a little detective that goes through each link and reports back what it found. 🔍✨

important vibe check: you should call this after connector detection is complete, so you can see the final state of all the links. like, don't call it mid-detection and then be confused. that's not the move. 😭
