Subject: [dpdk-stable] [PATCH v7 14/17] vdpa/mlx5: replace pthread functions unavailable in musl
Date: Fri, 19 Mar 2021 15:57:27 +0100
Message-ID: <20210319145730.3555384-15-thomas@monjalon.net> (raw)
In-Reply-To: <20210319145730.3555384-1-thomas@monjalon.net>

1/ The function pthread_yield() does not exist in musl libc,
and can be replaced with sched_yield() after including sched.h.

2/ The function pthread_attr_setaffinity_np() does not exist in musl libc,
and can be replaced with pthread_setaffinity_np() after pthread_create().

Fixes: b7fa0bf4d5c6 ("vdpa/mlx5: fix polling threads scheduling")
Fixes: 5cf3fd3af4df ("vdpa/mlx5: add CPU core parameter to bind polling thread")
