Subject: [PATCH v4 01/12] lib/Kconfig: add HAS_DMA_P2P for peer-to-peer support
Date: Wed, 22 Jul 2015 16:39:46 -0500 [thread overview]
Message-ID: <1437601197-6481-2-git-send-email-wdavis@nvidia.com> (raw)
In-Reply-To: <1437601197-6481-1-git-send-email-wdavis@nvidia.com>
This option is dependent on HAS_DMA, and indicates whether or not the DMA
API should include the peer resource (P2P) interfaces.
