dm_test_proc..._copies_data(9)
π NAME π
Okay so bestie, welcome to the Kernel API Manual (section 9, kernel internals, iykyk) β this page is all about dm_test_process_dmub_aux_transfer_sync_copies_data, and what it does is literally just test the AUX reply data copy. That's the whole vibe. No cap. π«Ά
β¨ SYNOPSIS β¨
void dm_test_process_dmub_aux_transfer_sync_copies_data (struct kunit
test );
π ARGUMENTS π
testβ the KUnit test context. That's it, that's the whole argument list, she's low maintenance. π
π¦ DESCRIPTION π¦
So here's the tea π: when a notification comes back successful, the sync helper should copy over the bounded reply data β bounded, bestie, keep that word in mind β¨ β and it should also report the high-nibble command reply when that reply is present. Highkey iconic behavior honestly. π
That's the whole check. No extra drama, no invented lore, she just verifies the copy-and-report flow on the happy path. π
