EPICS V4 Core

Interface Manager - need something to register and find interfaces.

• Could we generate a hash of the interface definition? Would allow us to compare interfaces and match two.

V4 Driver Interface

• Asyn Driver interfaces are now standardized, and are a good prototype for the V4 driver interface.
• In V4 the record types will directly talk to these driver interfaces.
• Hence device support will disappear in V4

We currently have interfaces for:

• value interface, for doing I/O and introspecting the value type
• connection interface, for connecting/dis-connecting devices
• Address parser? or is that part of connection?

Kay's point; device support needs to be able to introspect the record it belongs to, to get the scan rate for instance, or the display limits. Solution: give the driver the record's name (or some other record pointer) to allow the driver to use the db access routines to get at this data.
