Subject: [PATCH] vfio/iommufd: Add hw_caps field to HostIOMMUDeviceCaps
|
||
|
|
MIME-Version: 1.0

Content-Type: text/plain; charset=UTF-8

|
|
Store the value of @caps returned by iommufd_backend_get_device_info()
|
||
|
|
in a new field HostIOMMUDeviceCaps::hw_caps. Right now the only value is
|
||
|
|
whether device IOMMU supports dirty tracking (IOMMU_HW_CAP_DIRTY_TRACKING).
|
||
|
|
|
||
|
|
This is in preparation for HostIOMMUDevice::realize() being called early
|
||
|
|
during attach_device().
