Message-ID: <4AF3937C.3010505@mellanox.co.il> Date: Fri, 06 Nov 2009 05:09:48 +0200 From: Yevgeny Petrilin <yevgenyp@...lanox.co.il> To: rdreier@...co.com CC: linux-rdma@...r.kernel.org, netdev@...r.kernel.org, liranl@...lanox.co.il, tziporet@...lanox.co.il, yevgenyp@...lanox.co.il Subject: [PATCH 16/25 v2] mlx4_core: boot sriov From: Liran Liss <liranl@...lanox.co.il> Add virtual function device ids. Setting VF flag to device private data Establish comm channel when sriov is enabled, and boot vfs through it. Each slave gets one msi-X for completions, the master also gets one for async events.
