Out of curiosity: has this patch actually been tested on an armhf board
prior to releasing to me or stock ?
I do not known what patch you are talking about. But the I-pipe patches
are tested on omap3 and omap4, with armhf compilers before each release.
Now, if you are talking about the generation of Debian packages, 2.6.2
was released with a broken debian/rules, which was the main reason for
releasing 2.6.2.1. Now, I have to admit that I do not generate debian
packages, I let others do it.
I consider that validating Xenomai with armhf compiler proves that it
can work.
