Julien Olivain d46b2f5fea support/testing/infra/emulator.py: add host load info in run log
Runtime tests running on test runners are subject to a high
variability in term of performance and timing. Most or the runtime
test commands are executed with a timeout, in pexpect.

Slow or very loaded test runners can use the timeout_multiplier to
globally increase those timeouts.

Some runtime test commands sometimes needs to poll or query a state,
rather than having purely sequential actions. It is sometimes hard to
know, from the test writer point of view, the maximum timeout to set, or
if a retry logic is needed.

In order to help debugging runtime tests failing due very slow
execution, this commit adds extra information on the host test runner
about its load in the run log. Relevant information are: number of
cpus, the load average at the moment the emulator is started and the
current timeout_multiplier.

Note: this change was discussed in:

README

Buildroot is a simple, efficient and easy-to-use tool to generate embedded
Linux systems through cross-compilation.

The documentation can be found in docs/manual. You can generate a text
document with 'make manual-text' and read output/docs/manual/manual.text.
Online documentation can be found at http://buildroot.org/docs.html

To build and use the buildroot stuff, do the following:

1) run 'make menuconfig'
2) select the target architecture and the packages you wish to compile
3) run 'make'
4) wait while it compiles
5) find the kernel, bootloader, root filesystem, etc. in output/images

You do not need to be root to build or run buildroot.  Have fun!

Buildroot comes with a basic configuration for a number of boards. Run
'make list-defconfigs' to view the list of provided configurations.

Please feed suggestions, bug reports, insults, and bribes back to the
buildroot mailing list: buildroot@buildroot.org
You can also find us on #buildroot on OFTC IRC.
