Re: [Xen-devel] [RFC PATCH 00/19] xen/arm: Add ITS support



Hi Vijay,

The changes that I envisage for supporting Multiple ITS is
   - Generate as many number of ITS dt nodes for Dom0 that host DT contains.
   - For DomU always generate only one ITS node
   - vITS will register MMIO handlers for all physical ITS of Dom0, but
vITS will only have
     one VITS structure per domain. The limitation with this approach
is that all vITS requests are
     serialized even though there are more than one physical ITS. But
this approach makes
     implementation simple.

Each vITS will have his own command queue... How do you plan to handle it with only a single structure?

Can you provide an idea what the structure will look like?
