Subject: [PATCH RFC 0/3] x86/xen: pvclock vdso support
Date: Mon, 28 Dec 2015 21:52:34 +0000	[thread overview]
Message-ID: <1451339557-24473-1-git-send-email-joao.m.martins@oracle.com> (raw)

Hey!

This series proposes support for pvclock vdso under Xen: Patch 1 adds
setting cpu 0 pvti page; Patch 2 registers the pvti page with Xen and sets
it accordingly in pvclock and Patch 3 adds a Kconfig option since Xen
doesn't yet support the PVCLOCK_TSC_STABLE_BIT flag. Though its support
will probably be discussed in another RFC I sent[0].

Any comments or suggestions are welcome!

Thanks,
Joao
