The kernel file, first and foremost (this is the mothership 🚀):

./drivers/gpu/drm/amd/display/amdgpu_dm/tests/amdgpu_dm_backlight_test.c

And now the full squad, in order, no crumbs left behind ⭐:

like… sixty-nine cross-references, that's not a manpage that's a reunion 😭 and every single one is linked with (9), so you know they're all in the kernel API section, iykyk.

🌸 tiny reminder bestie: nothing here is optional reading if you're actually debugging this file — the whole list above lives right next to each other in amdgpu_dm_backlight_test.c, so if one test is acting up, its neighbours are usually the receipts. 🙈

and that's the page!! 💖 brought to you from ./drivers/gpu/drm/amd/display/..., dated October 2026, so like… future vibes only, bestie 🧚‍♀️ go forth and reject invalid text with confidence 💅✨🍓
