π i40e_pit_index_to_mask β Kernel API Manual, but make it a group chat
okay so bestie, welcome to the i40e_pit_index_to_mask(9) page from the Kernel API Manual β¨ it's a tiny little function but it's lowkey carrying the whole FLEX-mask situation, and honestly? iconic.
πΈ NAME πΈ
i40e_pit_index_to_mask β literally just returns the FLEX mask for a given PIT index π
β¨ SYNOPSIS β¨
u64 i40e_pit_index_to_mask (int pit_index );
so you hand it an int, you get back a u64. no cap. π
π¦ ARGUMENTS π¦
pit_indexβ the PIT index you want converted. that's it, that's the whole vibe check. π«Ά
π DESCRIPTION π
okay so the whole serve here: it returns the mask for a given PIT index. that's the moment. that's the main character energy. π₯
but listen β if the pit_index is out of range, it will return 0. not an error, not a freakout, just a flat 0. so if you get a 0 back and you're like "huh π", check your index first, bestie.
