This patch series improves the QMP client in lib XenLight to be able to insert a PCI passthrough device with the upstream QEMU. This require to apply a patch series for QEMU (named Xen PCI Passthrough). The first three patches are fix. The next patch creates a key in xenstore with the version of the running device model, here: /libxl/$domid/dm-version Changed since v2: > dm-version xenstore key patch: - small coding style improvement - libxl__device_model_version_running() now return an error on unexpected value in /libxl/$domid/dm-version > qmp_request_context patch: - rename handle to context - the context is now only used between qmp_sync.._send and qmp_send - return code of a callback is now return by qmp_sync.._send() > Handle number abrove LONG_MAX patch: - the new callback now also handle double. > two new patches to do a pci-detatch. Change v1-v2: - 3 new patches, with small fix. - add a structure in qmp, qmp_request_handle, to carry the return code of a callback. - the xenstore key for the dm-version is now in /libxl/$domid, instead of /local/domain/$domid - new patch to parse number bigger than LONG_MAX for json. - an user specified vdevfn for a pci passthrough devices is now handle. - in the last patch, the code to handle a pci-add through xenstore have is own function. that help a bit to keep the code under 80col. Anthony PERARD (13): libxl_qmp: Fix return check of fcntl libxl_json: Check the parser status before to call parse_complete libxl_qmp: Better error message after a parse error. libxl: Introduce dm-version xenstore key. libxl_qmp: Introduce an opaque argument to the callbacks. libxl_qmp: Introduce list of arguments to qmp_send libxl_qmp: Always insert a command id in the callback_list. libxl_qmp: Introduce qmp_request_context. libxl_json: Handle number abrove LONG_MAX. libxl_qmp: Introduce libxl__qmp_pci_add. libxl: Use QMP to insert a passthrough device when using upstream QEMU libxl_qmp: Introduce libxl__qmp_pci_del libxl: Remove a passthrough device through QMP. tools/libxl/libxl.c | 2 + tools/libxl/libxl_create.c | 29 +++++- tools/libxl/libxl_internal.c | 23 ++++ tools/libxl/libxl_internal.h | 19 +++- tools/libxl/libxl_json.c | 111 +++++++++++++------- tools/libxl/libxl_pci.c | 143 +++++++++++++++++-------- tools/libxl/libxl_qmp.c | 236 +++++++++++++++++++++++++++++++++++------ tools/libxl/libxl_xshelp.c | 9 ++ 8 files changed, 450 insertions(+), 122 deletions(-) -- Anthony PERARD _______________________________________________ Xen-devel mailing list Xen-devel@xxxxxxxxxxxxxxxxxxx http://lists.xensource.com/xen-devel
