π dm_test_hpd_rx_offload_work_no_connector β Kernel API Manual π
okay so bestie, this one lives in the Kernel API Manual (yes, the kernel has lore) and it's a KUnit test page. It's short, it's sweet, and it's giving "one job, done correctly." Let's get into it β¨
πΈ NAME πΈ
dm_test_hpd_rx_offload_work_no_connector β Test missing connector early exit π
That's the whole vibe: this test is here to check the missing-connector early exit path. No connector, early exit, test it. Periodt. π
β SYNOPSIS β
void dm_test_hpd_rx_offload_work_no_connector (struct kunit *test );
Yes that's the entire signature, she's a one-liner icon π
(and no, we are not "fixing" the space before that ) β it's exactly as written, don't @ me).
π¦ ARGUMENTS π¦
testβ The KUnit test context. That's it. That's the whole argument list. She takes one (1) parameter and she serves with it π«Ά
π SEE ALSO π
π The kernel file
- Kernel file β
./drivers/gpu/drm/amd/display/amdgpu_dm/tests/amdgpu_dm_irq_test.c
π The whole squad (a.k.a. every dm_test_* entry)
Like, genuinely the entire friend group is listed here, so here's the full roll call β no cap, every single one π
