Remote Computer Systems… Targets (Locally connected, shared, fielded) Hosts (Grids, farms, nodes) … and developing software on them Build, connect, get status Download, run, debug, test Upload An Eclipse Project under DSDP since June 2005.

23 Using and Extending the DSDP Target Management Framework | © 2006 by IBM and Wind River Systems all content except logos and trademarks is made available under the EPL v A New System Type – Whats Involved Extension points System Type Subsystem Subsystem implementations are assigned to System Types These can be reused across System Types System Types are just collections of services supplied by subsystems Example: Using only some of the existing services for a target

28 Using and Extending the DSDP Target Management Framework | © 2006 by IBM and Wind River Systems all content except logos and trademarks is made available under the EPL v This Linux target system shows up with 3 subsystems – using both dstore and FTP Our new XYZ target system shows up with 1 subsystem – using FTP

29 Using and Extending the DSDP Target Management Framework | © 2006 by IBM and Wind River Systems all content except logos and trademarks is made available under the EPL v Subsystems – access to resources Have a new kind of resource? Add a subsystem! Extension Point – The subsystem configuration Subsystems access resources through a service layer Not required, but a suggested implementation Useful if you have resources accessible by multiple protocols Lifecycle Connecting Applying filters to resources Definition persistence and sharing Subsystem Properties, Filter Definitions, Saved Commands Done through the SystemRegistry Pluggable Persistence Managers

30 Using and Extending the DSDP Target Management Framework | © 2006 by IBM and Wind River Systems all content except logos and trademarks is made available under the EPL v The Service Layer Do you have an alternative way to access a resource (like a file) that already has a subsystem? Just plug in a new service (well, sort of) No Extension Point for services, instead… Define a new subsystem configuration to act as a factory for the standard subsystem but connects that subsystem to the new service. The new subsystem configuration contributed in the usual way Standard subsystem defines the subsystem/service API File, Shell, and Process subsystems defined in this manner

41 Using and Extending the DSDP Target Management Framework | © 2006 by IBM and Wind River Systems all content except logos and trademarks is made available under the EPL v Or Indirectly

42 Using and Extending the DSDP Target Management Framework | © 2006 by IBM and Wind River Systems all content except logos and trademarks is made available under the EPL v RSE for the Device world – whats different? Different Resource Types, e.g. Kernel Modules, Semaphores, Message Queues Register a new Subsystem! Different communication protocols, e.g. minimal debug agents, hardware debuggers, standard protocols like ssh Register a new Service for existing Subsystems! Slow connections RSE model objects can use Jobs for delayed updates. Each node has control over its update policy! The RSE Model is extremely flexible thanks to Adapters. RSE APIs will be evolved as we go along.

43 Using and Extending the DSDP Target Management Framework | © 2006 by IBM and Wind River Systems all content except logos and trademarks is made available under the EPL v So whats still missing? Have a Framework for interoperability Focus on tools for remote (potentially embedded) systems Data models: basic PropertySetContainers now, need more structured models, standardized hardware descriptions Configure and Manage: connection configurations shared in a team, target groups, board labs, access restrictions Connection plug-ins: TCP/IP, Tunneling, Serial, JTAG connections – pluggable with fine granularity Pluggable Actions and Services (Download, Query status, Launch, Auto-detect services, Reboot, Flash utility, Remote console, …)

44 Using and Extending the DSDP Target Management Framework | © 2006 by IBM and Wind River Systems all content except logos and trademarks is made available under the EPL v Next Steps Add an RSE Service layer for the ssh protocol Files Subsystem and Command subsystem will work immediately Eclipse Committers can access dev.eclipse.org directly from within Eclipse (File Transfer, Remote Shell) Provides a nice example for how to add more protocol support Add a CDT Launch Integration Polish the APIs

49 Using and Extending the DSDP Target Management Framework | © 2006 by IBM and Wind River Systems all content except logos and trademarks is made available under the EPL v An FAQ: Where is the border between Target Management and Debugging? TM provides a framework and broker for services to be registered. Especially on Hardware Debug Connections, a debugger may register services as TM extension (TM on top of debugger) Or, TM may provide communication channels for debuggers to use (debugger on top of TM; inter-debugger communications) TM shows the entire target (e.g. all processes), debugger focuses on items of interest TM does everything before a debug context is available: Select proper target, check resource availability, reset, download, launch agent, …
