From mboxrd@z Thu Jan 1 00:00:00 1970 From: Jerone Young Date: Tue, 27 Nov 2007 20:42:51 +0000 Subject: [kvm-ppc-devel] [EXAMPLE] [PATCH] Framework for adding Powerpc Message-Id: <1196196171.7349.14.camel@thinkpad> List-Id: MIME-Version: 1.0 Content-Type: text/plain; charset="us-ascii" Content-Transfer-Encoding: 7bit To: kvm-ppc@vger.kernel.org Figured I would just put this on the list for the curious bunch. This is a small patch that is basically to show functions that have to be implemented for powerpc. This is an early patch in my personal repo .. but it's mainly to give an idea of the functions that are going into the libkvm-powerpc.c . Now once the kernel pieces get in place upstream this will be more filed out. Signed-off-by: Jerone Young Initial libkvm powerpc support These patches add initial code for powerpc. No big implimentations as kernel code is still being worked out. But it can be a good template for other architectures.
