[Intel-wired-lan] [PATCH net-next v4 6/8] ice: add individual interrupt allocation
Piotr Raczynski
piotr.raczynski at intel.com
Mon May 8 12:43:19 UTC 2023
Currently interrupt allocations, depending on a feature are distributed
in batches. Also, after allocation there is a series of operations that
distributes per irq settings through that batch of interrupts.
Although driver does not yet support dynamic interrupt allocation, keep
allocated interrupts in a pool and add allocation abstraction logic to
make code more flexible. Keep per interrupt information in the
ice_q_vector structure, which yields ice_vsi::base_vector redundant.
Also, as a result there are a few functions that can be removed.
