Subject: [PATCH 0/2] Implement VFP context switch for arm32
Date: Thu, 30 May 2013 15:38:51 +0100 [thread overview]
Message-ID: <1369924733-18701-1-git-send-email-julien.grall@linaro.org> (raw)
Hello,
This small patch series implement the VFP context for arm32.
I didn't implement the arm64 support, and just add dummy function to avoid
compilation breakage on this platform.
The second patch remove VFP support on XEN because we can let the guest
to enable when it's required by a process.
Cheers,
