From eb826444f90c2563dadf148630b0cd6a9b41ba1e Mon Sep 17 00:00:00 2001
From: Eric Blake <eblake@redhat.com>
Date: Mon, 27 Sep 2010 10:10:06 -0600
Subject: [PATCH 05/15] vcpu: implement the remote protocol
Done by editing the first three files, then running
'make -C src rpcgen', then editing src/remote_protocol-structs
to match.
* daemon/remote.c (remoteDispatchDomainSetVcpusFlags)
(remoteDispatchDomainGetVcpusFlags): New functions.
* src/remote/remote_driver.c (remoteDomainSetVcpusFlags)
(remoteDomainGetVcpusFlags, remote_driver): Client side
serialization.
* src/remote/remote_protocol.x
(remote_domain_set_vcpus_flags_args)
(remote_domain_get_vcpus_flags_args)
(remote_domain_get_vcpus_flags_ret)
(REMOTE_PROC_DOMAIN_SET_VCPUS_FLAGS)
(REMOTE_PROC_DOMAIN_GET_VCPUS_FLAGS): Define wire format.
* daemon/remote_dispatch_args.h: Regenerate.
* daemon/remote_dispatch_prototypes.h: Likewise.
* daemon/remote_dispatch_table.h: Likewise.
* src/remote/remote_protocol.c: Likewise.
* src/remote/remote_protocol.h: Likewise.
* src/remote_protocol-structs: Likewise.
