I suppose it's a bit of a grey area, obviously the file format is "ABI", but its not one a user should ever interact with directly. What I'm getting at is may most of this should be in the libxl__ rather than libxl_ namespace (also some of it being un-namespaced would further suggest these are strictly speaking install, as would the fact it isn't installed...) > Signed-off-by: Ross Lagerwall <ross.lagerwall@xxxxxxxxxx> > Signed-off-by: Andrew Cooper <andrew.cooper3@xxxxxxxxxx> > CC: Ian Campbell <Ian.Campbell@xxxxxxxxxx> > CC: Ian Jackson <Ian.Jackson@xxxxxxxxxxxxx> > CC: Wei Liu <wei.liu2@xxxxxxxxxx> > --- > tools/libxl/libxl_sr_stream_format.h | 57 > ++++++++++++++++++++++++++++++++++ > 1 file changed, 57 insertions(+) > create mode 100644 tools/libxl/libxl_sr_stream_format.h > > diff --git a/tools/libxl/libxl_sr_stream_format.h > b/tools/libxl/libxl_sr_stream_format.h > new file mode 100644 > index 0000000..487f9e2 > --- /dev/null > +++ b/tools/libxl/libxl_sr_stream_format.h > @@ -0,0 +1,57 @@ > +#ifndef LIBXL_SR_STREAM_FORMAT_H > +#define LIBXL_SR_STREAM_FORMAT_H > + > +/* > + * C structures for the Migration v2 stream format. > + * See docs/specs/libxl-migration-stream.pandoc > + */ > + > +#include <stdint.h> > + > +typedef struct libxl_sr_hdr > +{ > + uint64_t ident; > + uint32_t version; > + uint32_t options; > +} libxl_sr_hdr; > + > +#define RESTORE_STREAM_IDENT 0x4c6962786c466d74UL > +#define RESTORE_STREAM_VERSION 0x00000002U > + > +#define RESTORE_OPT_BIG_ENDIAN (1 << 0) > +#define RESTORE_OPT_LEGACY (1 << 1) > + > + > +typedef struct libxl_sr_rec_hdr > +{ > + uint32_t type; > + uint32_t length; > +} libxl_sr_rec_hdr; > + > +/* All records must be aligned up to an 8 octet boundary */ > +#define REC_ALIGN_ORDER 3U > + > +#define REC_TYPE_END 0x00000000U > +#define REC_TYPE_LIBXC_CONTEXT 0x00000001U > +#define REC_TYPE_XENSTORE_DATA 0x00000002U > +#define REC_TYPE_EMULATOR_CONTEXT 0x00000003U > + > +typedef struct libxl_sr_emulator_hdr > +{ > + uint32_t id; > + uint32_t index; > +} libxl_sr_emulator_hdr; > + > +#define EMULATOR_UNKNOWN 0x00000000U > +#define EMULATOR_QEMU_TRADITIONAL 0x00000001U > +#define EMULATOR_QEMU_UPSTREAM 0x00000002U > + > +#endif /* LIBXL_SR_STREAM_FORMAT_H */ > + > +/* > + * Local variables: > + * mode: C > + * c-basic-offset: 4 > + * indent-tabs-mode: nil > + * End: > + */ _______________________________________________ Xen-devel mailing list Xen-devel@xxxxxxxxxxxxx http://lists.xen.org/xen-devel
