dm_test_atom...r_lut_bypass(9)
πΈ dm_test_atom...r_lut_bypass(9) β a Kernel API Manual moment π
ok so bestie, you found a page in the Kernel API Manual, and the title up top is literally dm_test_atom...r_lut_bypass(9) β yes the ellipsis is on purpose, the man header just truncates the long name, don't come for me. Sit down, hydrate, and let's get into it π«Ά
β¨ NAME β¨
dm_test_atomic_shaper_lut_bypass β No LUT and linear TF: must take bypass path π―
That's the whole vibe. No LUT, linear transfer function, so the code is required to take the bypass path. Periodt.
π¦ SYNOPSIS π¦
void dm_test_atomic_shaper_lut_bypass (struct kunit *test );
literally that's it, bestie. one call, no return value, in we go π
π ARGUMENTS π
testβ the KUnit test context π§ͺ β the little handle the test framework hands you so you can assert stuff and not vibe-check into the void.
π SEE ALSO π
This is the part where the manpage dumps the entire friend group β the whole color-management test squad, no cap. Every single one, in order, fr fr:

bestie that list is long and I did not skip a single one, because every one of these is somebody's hyperfixation and we respect it π
π ok that's the page π
That's the whole thing β tiny page, big friend group. Go read the tests, they're lowkey iconic π
sign-off time: this little gem lives down at ./drivers/gpu/drm/amd/display/... and it's stamped October 2026, with the header reading dm_test_atom...r_lut_bypass(9) from the Kernel API Manual. mwah πβ¨
