okay so this is a page from the Kernel API Manual β yes bestie, the Kernel API Manual, we're doing kernel networking today and honestly? it's giving main character energy. grab a strawberry π and let's get into it.
πΈ NAME πΈ
ixgbevf_alloc_q_vectors β the function whose whole entire job is allocating memory for interrupt vectors. that's it. that's the gig. π
π¦ SYNOPSIS π¦
int ixgbevf_alloc_q_vectors (struct ixgbevf_adapter *adapter );
like, literally just call it with your adapter pointer and it returns an int. no drama, no cap.
π ARGUMENTS π
adapterβ the board private structure you're initializing. that's your baby, that's the thing you're setting up. hand it over and let the function do its thing. π«Ά
π DESCRIPTION π
okay so the tea β: we allocate one q_vector per queue interrupt. one queue interrupt β one q_vector. matching set. iconic behavior, honestly.
and if the allocation fails? we return -ENOMEM. yep. that's the error code, that's what you get, -ENOMEM stands for "no memory" and it's the moment where everything just... doesn't work out. π keep that in mind β if allocation fails, the return value is -ENOMEM, periodt.
