dm_test_dp_r...dpcd_success(9)

πŸ“¦ version 7.3.1, in nixpkgs unstable

πŸ’– dm_test_dp_r...dpcd_success(9) β€” a Kernel API Manual moment πŸ’–

okay so literally first things first bestie: this is a page from the Kernel API Manual, and today's main character is dm_test_dp_read_dpcd_success β€” the header even abbreviates it to dm_test_dp_r...dpcd_success(9) because apparently even manpage headers get tired 😭. It's a KUnit test, it's in the AMD display driver tests, and it's giving "tiny function, huge friend group" energy, because the SEE ALSO list is enormous. Buckle up πŸŽ€


✨ NAME ✨

dm_test_dp_read_dpcd_success β€” the test that checks a DPCD read comes back true on an ACKed transfer. slay. that's it. that's the whole job πŸ’…


🌸 SYNOPSIS 🌸

void dm_test_dp_read_dpcd_success (struct kunit *test );

like yes that's the whole signature, no cap. void return, one argument, iconic minimalism ✨


πŸ¦‹ ARGUMENTS πŸ¦‹

  • test β€” the KUnit test context 🧚 that's the only thing it takes, and it's the little context-shaped buddy every KUnit test gets handed so it can do its thing.

πŸ‘‘ SEE ALSO πŸ‘‘

okay so the "Kernel file" for this one lives right here β€” copy it exactly, bestie, don't be weird about it:

./drivers/gpu/drm/amd/display/amdgpu_dm/tests/amdgpu_dm_helpers_test.c

and now… the guest list πŸ’€. this is the entire friend group, in order, and yes we are listing every single one because they all deserve their moment:

bestie note 🫢: that whole list is literally just the other tests hanging out in the same neighbourhood β€” if you're here for the DPCD read, you're in the right group chat. iykyk πŸ’œ

and that's the vibe check, complete ✨. this page came from the Kernel API Manual source line ./drivers/gpu/drm/amd/display/... and it's dated October 2026, with the footer rounding it out as dm_test_dp_r...dpcd_success(9). go read the kernel file, it's literally right there, ily, bye πŸŽ€πŸ’–πŸ¦‹
