* python-pgo-image: change python3 profile target to pybenchmarquiz/fixes-9338-v2Markus Lehtonen2017-05-171-5/+6
| | | | | | | | | | Running test.regrtest was still taking ridiculously long, i.e. around 4 hours in qemux86 on my desktop machine. Change to pybench which "only" takes around 55 minutes. [YOCTO #9338] Signed-off-by: Markus Lehtonen <markus.lehtonen@linux.intel.com>
* python-pgo-image: exclude tests from the python3 profile targetMarkus Lehtonen2017-05-171-0/+5
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Exlude failing tests (on qemux86 target) which would cause the profile task to fail. Also, disable some very long running tests.

* python-pgo-image: profiling for python3Markus Lehtonen2017-05-171-12/+45
| | | | | | | | | | | | Add a new 'do_profile3' task for python-pgo-image that runs profiling task for python3 and retrieves the profile data, similarly to 'do_profile' for python2. Profile data will be copied into a directory pointed by PYTHON3_PROFILE_DIR on the host system. The profile task may be specified with PYTHON3_PROFILE_TASK.

* python-pgo-image: enable sstate for do_profileMarkus Lehtonen2017-05-171-2/+13
| | | | | | | | | | | | | | | | | | There are caveats however, basically because of the circular dependency between python-pgo-image and python (python is a build dep of python-pgo-image, and at the same time, depends on the profile data generated by python-pgo-image). In practice the sstate data is only used when no profile data is yet present. Existing profile data (i.e. non-empty PYTHON_PROFILE_DIR) changes signature hash of python which, in turn, changes signature of python-pgo-image and causes a sstate signature mismatch and rebuild of python-pgo-image. Thus, in order to utilize sstate data the user should run "bitbake python-pgo-image -c clean" (or otherwise wipe pre-existing profile data) before running "bitbake python-pgo-image -c profile".

* python-pgo-image: switch python default profile task to pybenchMarkus Lehtonen2017-05-171-8/+10

* python-pgo-image: exclude tests from the default profile targetMarkus Lehtonen2017-05-171-1/+8
| | | | | | | | | | | | | | | Exclue tests that are segfaulting or otherwise failing (on qemux86 target), and thus, causing the profile task to fail. Also, disable tests that are taking very long to execute.

* devtools/images: add python-pgo-imageMarkus Lehtonen2017-05-171-0/+62
This is a special image for profiling Python in order to utilize profile-guided-optimization. Profile data can be obtained by by running bitbake python-pgo-image -c profile. It will be located in the directory pointed by ${PYTHON_PROFILE_DIR}. The profile task that is run can be altered by specifying ${PYTHON_PROFILE_TASK}.
