Subject: [PATCH v7 2/8] irqchip/gic-v3-its: ITS advertises MSI_FLAG_IRQ_REMAPPING
Date: Tue, 19 Apr 2016 17:13:04 +0000 [thread overview]
Message-ID: <1461085990-2547-3-git-send-email-eric.auger@linaro.org> (raw)
In-Reply-To: <1461085990-2547-1-git-send-email-eric.auger@linaro.org>
The ITS is the first ARM MSI controller advertising the new
MSI_FLAG_IRQ_REMAPPING flag. It does so because it supports
interrupt translation service. This HW support offers isolation
of MSIs, feature used when using KVM device passthrough.
