dm_test_fun...dp_abm_level(9)

💖 NAME 💖

okay bestie, welcome to the dm_test_fun...dp_abm_level(9) page from the Kernel API Manual ✨. This one is dm_test_funcs_reset_edp_abm_level — literally a KUnit test for checking that funcs_reset eDP sets ABM. It’s giving “tiny but important connector test” energy 💅.

✨ SYNOPSIS ✨

The whole signature is right here, no cap:

void dm_test_funcs_reset_edp_abm_level (struct kunit *test );

🎀 ARGUMENTS 🎀

• test — The KUnit test context. That’s the entire argument list, bestie 🫶.
