Subject: [PATCH] dma/skeleton: fix pthread set affinity
Date: Sat, 12 Aug 2023 07:27:38 +0530 [thread overview]
Message-ID: <20230812015738.1024-1-vipin.varghese@amd.com> (raw)
In skeleton dma driver, the user can pin the dma thread to desired
cpu core. The previous commit changed the api from set-affinity to
get-affinity leading to thread to be pinned to first available lcore.
Bugzilla ID: 1270
Fixes: 7fdf30d8b259 ("eal/windows: remove most pthread lifetime shim functions")
