Add ITS support for arm. Following major features
are supported
- GICv3 ITS support for arm64 platform
- Supports multi ITS node
- LPI descriptors are allocated on-demand
- Only ITS Dom0 is supported
Tested with single ITS node.
Some though about the whole design:
Your vGIC ITS driver does too much things. In general a virtual driver
should only emulate the hardware for the domain and forward the request
to the physical driver.
Your series adds device management (create/free) in the vITS, which is
wrong.
How do you check if the domain can use the device?
Currently, you allow any domain to use any device. That would bring a
big mess with guest using passthrough.
Also, does the guess will always pass the correct devid? If not how do
you plan to handle it?
