Subject: [dpdk-dev] [PATCH v2 07/29] bus/fslmc: support portal migration
Date: Tue,  7 Jul 2020 14:52:22 +0530
Message-ID: <20200707092244.12791-8-hemant.agrawal@nxp.com> (raw)
In-Reply-To: <20200707092244.12791-1-hemant.agrawal@nxp.com>

From: Nipun Gupta <nipun.gupta@nxp.com>

The patch adds support for portal migration by disabling stashing
for the portals which is used in the non-affined threads, or on
threads affined to multiple cores

Signed-off-by: Nipun Gupta <nipun.gupta@nxp.com>
