dm_test_wri...able_disable(9) β Kernel API Manual
okay so bestie, welcome to the group chat for this one lil KUnit test π. It lives in the Kernel API Manual, and yes the title is truncated with ... β that's just how this page rolls, we don't question it πΈ.
β¨ NAME β¨
dm_test_write_payload_alloc_table_disable β it's the test for the remove-payload success path, periodt π₯. That's the whole vibe: poke the remove-payload flow, confirm it goes through like a good little function π«Ά.
π SYNOPSIS π
void dm_test_write_payload_alloc_table_disable (struct kunit *test );
like, it returns nothing (it's a void, bestie, it's got nothing to prove π
) and it takes exactly one argument. Iconic minimalism.
π¦ ARGUMENTS π¦
testβ The KUnit test context π. This is literally the test-framework handbag she carries around; it's the thing KUnit hands you so the test can do test things. No cap, that's it, that's the whole argument list.
π SEE ALSO π
okay this is the part where she tags literally everyone in the function family π. The kernel file this lives in is:
./drivers/gpu/drm/amd/display/amdgpu_dm/tests/amdgpu_dm_helpers_test.c
