Subject: [dts] [PATCH 2/4] tests/power_bidirection_channel: change core masks
Date: Wed, 7 Apr 2021 09:18:05 +0100 [thread overview]
Message-ID: <20210407081807.29110-2-reshma.pattan@intel.com> (raw)
In-Reply-To: <20210407081807.29110-1-reshma.pattan@intel.com>
Change the vm_power_manager and gues_cli app
core masks. Now with dpdk 20.11 the cores used for guest_cli
should be enabled in vm_power_manager core mask.
Otherwise vm_power_manager will not grant the access to
fetch the information for those cores missing in the coremask.
Relevant DPDK patch
