Remaining work for a fully functional toolchain CI loop at Ubuntu LEB

==========

Notes from the session:

 Marcin created a gcc linaro package and cross toolchain packages from gcc-ubuntu and gcc-linaro
 cross-toolchain packages need to be tested on x86
 Michael normally runs the gcc testsuite in qemu for his testing
 for build testing, builds packages natively with testsuites in them
 Problem with testing packages is that it's easy to cross-build them, but not test - core packages have some test wrapper script
 some packages have support for pushing binaries to a remote machine for testing - need a bit of setup with a board file that will tell it where to push the packages for testing

one approach would be to build cross compiler in cloud, build arm packages with this compiler and then submit the built packages to be tested in LAVA

Test support:
 * Native package build
 * Test execution at the package set that was natively built (current package set is 'build-essential')
 * Cross package build at the cloud, probably via jenkins
 * Test execution with the packages built using the cloud, after giving the packages and the test request at lava
  * Packages and test descriptions get queued in LAVA, results land somewhere

Stage one:
 1) Native build native test. Cross build
 2) lower prio - native test of the cross-built package

Would like to have some sort of event saying if something fails

1. Currently planning to do daily builds of both the native and cross package (dailydeb recipe via lp)
Available via staging ppa
2. Another ppa would have a source package set that we define for building using the above, and running tests - just so that we can get source
3. Pull the above source packages in a cloud (jenkins) instance, and build them using the binaries from step 1
This produces a build result into lava
4. a job is submitted to lava to get the unittest package produced by step 3 and run it natively

This could be used to cross/native build the benchmarks and run the tests

Michael Hope would like to archive the old packages somewhere - need to dump it to a directory on a web server somewhere to preserve it (could probably use the nas box in the lab)
ACTION: Marcin to check if the bzr recipe is still broken after Launchpad updated the bzr package to a newer version
ACTION: Danilo to check if there is a way to disable package purge once a new package is pushed to the ppa
ACTION: Michael to provide the package list that we'd use to test the toolchain
Marcin:
 - Create the test definition at LAVA for the native test
 - Create the test definition at jenkins to run at the cloud
    - Also push the results to Lava's dashboard
