GDB as a cross-debugger

Registered by Michael Hope on 2011-04-28

Last cycle Linaro focused on bringing native GDB on ARM up to par with x86. Many end-developer projects are done in a cross environment. Discuss the tools used in cross debug such as gdbserver, bringing cross debug up to par with native GDB, adding tracepoints and fast tracepoints, and any host side issues such as multiarch integration.

Whiteboard

Headline: Bring cross debug up to par with native GDB, adding tracepoints and fast tracepoints, and any host side issues such as multiarch integration.

Acceptance: Run GDB testsuite via gdbserver and check remote access

Additional feedback from UDS:
- Verify multi-arch setup is working well for cross-debugging
- Integrate debugger into dbgsym package retrieval (cross & native)
- Verify "remote:" access to libraries works & is stable
- Improving KGDB kernel debugging (e.g. automatic module symbols)
- Support GDB tracepoints on native as well
- Add capability to collect timestamp at tracepoints
