Subject: [PATCH for-5.0 v11 02/20] virtio-iommu: Add skeleton
Date: Fri, 22 Nov 2019 19:29:25 +0100 [thread overview]
Message-ID: <20191122182943.4656-3-eric.auger@redhat.com> (raw)
In-Reply-To: <20191122182943.4656-1-eric.auger@redhat.com>
This patchs adds the skeleton for the virtio-iommu device.
Signed-off-by: Eric Auger <eric.auger@redhat.com>
---
v9 -> v10:
- mutex initialized here
- initialize tail
- included hw/qdev-properties.h
- removed g_memdup
- removed s->config.domain_range.start = 0;
v9 -> v10:
- expose VIRTIO_IOMMU_F_MMIO feature
- s/domain_bits/domain_range struct
- change error codes
- enforce unmigratable
- Kconfig
v7 -> v8:
- expose VIRTIO_IOMMU_F_BYPASS and VIRTIO_F_VERSION_1
features
- set_config dummy implementation + tracing
- add trace in get_features
- set the features on realize() and store the acked ones
- remove inclusion of linux/virtio_iommu.h
v6 -> v7:
- removed qapi-event.h include
- add primary_bus and associated property
v4 -> v5:
- use the new v0.5 terminology (domain, endpoint)
- add the event virtqueue
v3 -> v4:
- use page_size_mask instead of page_sizes
- added set_features()
- added some traces (reset, set_status, set_features)
- empty virtio_iommu_set_config() as the driver MUST NOT
write to device configuration fields
- add get_config trace
v2 -> v3:
- rebase on 2.10-rc0, ie. use IOMMUMemoryRegion and remove
iommu_ops.
- advertise VIRTIO_IOMMU_F_MAP_UNMAP feature
- page_sizes set to TARGET_PAGE_SIZE
