π dm_test_vali..._gfx12_fails(9)
okay so bestie, welcome to the Kernel API Manual β¨ this little page is all about one very specific KUnit test, and honestly? she's niche, she's focused, and she knows exactly what she's here to do π
πΈ NAME πΈ
dm_test_validate_dcc_video_non_gfx12_fails β literally just verifying the video format restriction on pre-GFX12 π
no cap
β¨ SYNOPSIS β¨
void dm_test_validate_dcc_video_non_gfx12_fails (struct kunit *test );
that's it, that's the whole vibe π«Ά
π¦ ARGUMENTS π¦
testβ the KUnit test context π like, the little handbag she carries all her test state in, yk?
π DESCRIPTION π
so the whole point, fr fr: this one verifies whether video format DCC validation fails on non-GFX12 devices π
that's the mission. that's the assignment. she understood it, she ate, she left no crumbs π
ngl the entire thing hinges on one word: non-GFX12. pre-GFX12 hardware is supposed to reject this video format DCC validation, and this test is the one making sure that actually happens π
