From mboxrd@z Thu Jan 1 00:00:00 1970 From: Alex Williamson Subject: [PATCH] vfio: Depend on EVENTFD Date: Tue, 17 Mar 2015 08:42:15 -0600 Message-ID: <20150317144057.20251.30522.stgit@gimli.home> Mime-Version: 1.0 Content-Type: text/plain; charset="utf-8" Content-Transfer-Encoding: 7bit Cc: a.motakis@virtualopensystems.com, b.reynal@virtualopensystems.com, linux-kernel@vger.kernel.org, eric.auger@linaro.org To: kvm@vger.kernel.org Return-path: Sender: linux-kernel-owner@vger.kernel.org List-Id: kvm.vger.kernel.org Since commit 42ac9bd18d4f ("vfio: initialize the virqfd workqueue in VFIO generic code"), vfio itself depends on EVENTFD support. Add this to Kconfig to enforce the dependency. This could perhaps become a soft dependency if there was sufficient interest to make it more modular, but eventfds are currently an integral part of vfio interrupt delivery for all vfio bus drivers.
