X-Received-From: 66.165.176.63 Cc: xen-devel@lists.xensource.com, Ian Campbell , Stefano Stabellini Subject: [Qemu-devel] [PATCH] compile QEMU with Xen support on ARM X-BeenThere: qemu-devel@nongnu.org X-Mailman-Version: 2.1.14 Precedence: list List-Id: List-Unsubscribe: , List-Archive: List-Post: List-Help: List-Subscribe: , Errors-To: qemu-devel-bounces+incoming=patchwork.ozlabs.org@nongnu.org Sender: qemu-devel-bounces+incoming=patchwork.ozlabs.org@nongnu.org Fixes to build QEMU with Xen support on ARM and ARM64. Most fixes are due to the fact that xen_pfn_t is 64-bit sized on arm32, while it is an unsigned long on x86_32. Although QEMU can be compiled with full emulation support, on ARM we only care about the PV backends.
