Hi, Kirti,
We decide to go with above type-based interface for KVMGT, with fixed setup
of attributes too. If both Intel and NVIDIA solutions use such fixed manner,
can we go with a proposal which doesn't include 'class' extension for now?
Later if there is a concrete usage requiring such class-specific attribute setting,
then it's easy to extend following discussion in this thread. I'm thinking how we
can converge the discussion here into something simple enough (and extensible)
to accelerate upstreaming of both Intel/NVIDIA solutions...
Thanks
Kevin
