From f771314d6b75181de7079c3c7d666293e4ed2b22 Mon Sep 17 00:00:00 2001 From: Alexander Lobakin Date: Thu, 20 Jun 2024 15:53:42 +0200 Subject: idpf: compile singleq code only under default-n CONFIG_IDPF_SINGLEQ Currently, all HW supporting idpf supports the singleq model, but none of it advertises it by default, as splitq is supported and preferred for multiple reasons. Still, this almost dead code often times adds hotpath branches and redundant cacheline accesses. While it can't currently be removed, add CONFIG_IDPF_SINGLEQ and build the singleq code only when it's enabled manually. This corresponds to -10 Kb of object code size and a good bunch of hotpath checks. idpf_is_queue_model_split() works as a gate and compiles out to `true` when the config option is disabled.
