Subject: [Xenomai] Lacking xsave support in Xenomai
Date: Fri, 25 Jan 2013 15:06:40 +0100	[thread overview]
Message-ID: <51029170.7070104@siemens.com> (raw)

Hi all,

yesterday I pushed a fix to my for-upstream queue that properly disables
all xsave-dependent CPU features (AVX/AVX2 namely). However, this is no
real solution for us as it blocks a lot of acceleration potential on
current Intel CPUs.

Did anyone already look into this in more details? Is it just a matter
of implementing the necessary context switching bits? Are there known
pitfalls?
