okay so first thing, bestie, don't come for me about the name β this manual page is literally called dm_test_colo...om_info_bpc8(9), dots and all. That's the header, that's canon, that's the vibe. It's a kernel API manual page and we're gonna get through it together, no cap. π«Ά
β¨ NAME β¨
dm_test_color_depth_from_info_bpc8 β the test that checks Color depth from info bpc8. That's it, that's the whole name section, she's short and she knows it π
πΈ SYNOPSIS πΈ
void dm_test_color_depth_from_info_bpc8 (struct kunit *test );
look at her, one line, zero drama, returns nothing, takes exactly one thing. iconic behavior honestly β
π ARGUMENTS π
testβ the KUnit test context. that's the whole assignment. she shows up, she holds the context, she slays π

so real talk, this is the long part, and we are NOT skipping it, because every single one of these is part of the family and they all deserve their moment. first up, the actual kernel file where this lives:
Kernel file β ./drivers/gpu/drm/amd/display/amdgpu_dm/tests/amdgpu_dm_connector_test.c
and now, the extended friend group, in order, no one left behind π:
