[dpdk-dev] [PATCH 2/3] travis: add a distinguisher to the 'extra' builds

[Aaron Conole]

This helps in two ways:
  1. When looking at travis page for dpdk, it's a visual distinction

  2. For ccache support, the build IDs include the 'env', so we get unique
     cache data.

[dpdk-dev] [PATCH 3/3] app/test/meson: auto detect number of cores

[Aaron Conole]

The arguments being passed will cause failures on laptops that have,
for instance, 2 cores only.  Most of the tests don't require more
than a single core.  Some require multiple cores (but those tests
should be modified to 'SKIP' when the correct number of cores
aren't available).

The unit test results shouldn't be impacted by this change, but it
allows for a future enhancement to pass flags such as '--no-huge'.

Also include a fix to a reported issue with running on FreeBSD.

nit: Retrieve

Little concern here on the approach of getting the max available cpu index.
If we have non contiguous cpus (let's say hyper threading is disabled),
this won't work.
But we can just assume this won't happen for non regression setups (vms).

lscpu is a linux command afaik.

Maybe for FreeBSD:
root@freebsd-10:~ # sysctl dev.cpu |cut -d . -f 3 |sort |tail -1
3

Not sure if FreeBSD ensures that the keys names/objects won't change
accross the versions.

Very similar thoughs/concerns here. I think doing this per OS is probably
safer in the long term - even though lscpu is available for FreeBSD as an
extra package.

My suggestion: for FreeBSD, get the number of CPUs using
	"/sbin/sysctl -n hw.ncpu"
For Linux, rather than using a "0-N" range, use output from 
"cat /sys/devices/system/cpu/present", which will ensure that it works
even in the non-contiguous CPU numbering case. [Though I suspect we get
non-contiguous numbers only in the case a core or two has been hotplugged
out, I think - disabling hyperthreading won't leave gaps, just fewer cores]

[dpdk-dev] [PATCH v2 0/3] travis: enhancements for build (plus a meson fix)

[Aaron Conole]

This series improves the travis integration a bit, and adds the ability for
the meson system to auto-detect the number of cores.

v1->v2 (all patch 3/3 changes):
* Fix a spelling mistake
* Add support for FreeBSD
* Include a default fallback
* Use a more robust core-mask argument source (rather than lscpu)

Aaron Conole (3):
  travis: enable ccache
  travis: add a distinguisher to the 'extra' builds

[dpdk-dev] [PATCH v2 3/3] app/test/meson: auto detect number of cores

[Aaron Conole]

The arguments being passed will cause failures on laptops that have,
for instance, 2 cores only.  Most of the tests don't require more
than a single core.  Some require multiple cores (but those tests
should be modified to 'SKIP' when the correct number of cores
aren't available).

The unit test results shouldn't be impacted by this change, but it
allows for a future enhancement to pass flags such as '--no-huge'.

Also include a fix to a reported issue with running on FreeBSD.

The unit test results shouldn't be impacted by this change, but it
allows for a future enhancement to pass flags such as '--no-huge'.

Also include a fix to a reported issue with running on FreeBSD.

This -n 4 parameter can be dropped. Four is the default setting IIRC.
I also wonder are the parameters coming through to the app correctly,
generally meson does not work well with parameters with spaces in them -
I'd expect the "-l" and the num_cores values to be separated in the array.
I also think num_cores_arg value could be dropped too.

If it works though, I'm ok to keep as-is though.

While this is needed now, I think in the medium term we should have the
"file-prefix" flag being a warning rather than a hard-error on FreeBSD.
[i.e. keep this, but we should fix it in 19.08 to be shorter]

For another patch.  I thought about doing it with this one, but I'd
rather keep the changes a little bit traceable.  If you think I should
resubmit with it dropped, I will.

It does work.  Actually, I needed to change because on some of the VM
setups (including the one used by Travis) the '-c f' arg errors because
it wants 4 cores, and only 2 exist.  Either way, this patch doesn't
change the spacing being passed with args :)

Applied, thanks

For info, we can also cache the build directory with
	cache:
	  directories:
	    - path/to/meson/build/dir
See https://docs.travis-ci.com/user/caching/#arbitrary-directories.
