Added by Artem Zhmurov 17 days ago

Make OpenCL DeviceVendor into enum class and move to GPU traits

The device context in OpenCL requires the information on vendor when
constructed. To prepare for opaque DeviceContext, the vendor
enum was moved into OpenCL traits.

Refs. #3311, needed for #3315.

Revision e742ad10 (diff)
Added by Artem Zhmurov 17 days ago

Move DeviceInfo into GPU traits

The DeviceInfo is needed upon construction of DeviceContext. To
prepare for opaque DeviceContext type, it is moved to GPU traits
and renamed according to the common naming scheme.

Refs. #3311, needed for #3315.
