From: Philip Yang Philip.Yang@amd.com
SVMAPISupported property added to HSA_CAPABILITY, the value match HSA_CAPABILITY defined in Thunk spec:
SVMAPISupported: it will not be supported on older kernels that don't have HMM or on GFXv8 or older GPUs without support for 48-bit virtual addresses.
CoherentHostAccess property added to HSA_MEMORYPROPERTY, the value match HSA_MEMORYPROPERTY defined in Thunk spec:
CoherentHostAccess: whether or not device memory can be coherently accessed by the host CPU.
