Subject: [PATCH 27/27] tools: add hmm gup test for long term pinned device pages
Date: Thu, 10 Feb 2022 08:28:28 +0100	[thread overview]
Message-ID: <20220210072828.2930359-28-hch@lst.de> (raw)
In-Reply-To: <20220210072828.2930359-1-hch@lst.de>

From: Alex Sierra <alex.sierra@amd.com>

The intention is to test device coherent type pages that have been
called through get user pages with PIN_LONGTERM flag set. These pages
should get migrated back to normal system memory.
