Subject: [PATCH 0/3] virtio-iommu: Support VIRTIO_IOMMU_F_BYPASS_CONFIG
Date: Thu, 30 Sep 2021 19:50:48 +0100 [thread overview]
Message-ID: <20210930185050.262759-1-jean-philippe@linaro.org> (raw)
Replace the VIRTIO_IOMMU_F_BYPASS feature with
VIRTIO_IOMMU_F_BYPASS_CONFIG, which enables a config space bit to switch
global bypass on and off.
Add a boot-bypass option, which defaults to 'on' to be in line with
other vIOMMUs and to allow running firmware/bootloader that are unaware
of the IOMMU.
See the spec change for more rationale
