Revision bumped to 4 for new IO support, enabled for spice-server >=
0.11.1. New io enabled iff spice-server >= 0.11.1 && spice-protocol >=
0.12.0.

On migration reissue spice_qxl_monitors_config_async.

Patch doesn't apply cleanly to master.

/me thinks now with spice-server having no dependency any more on
spice-protocol we should add a #define SPICE_PROTOCOL_VERSION to
spice-protocol so we don't need constructs like this.

Or maybe just use

#ifndef QXL_HAS_IO_MONITORS_CONFIG_ASYNC
#define QXL_HAS_IO_MONITORS_CONFIG_ASYNC $whatever
#endif

?

Can be on a single line:

#if (SPICE_SERVER_VERSION >= 0x000b01) &&
defined(QXL_HAS_IO_MONITORS_CONFIG_ASYNC)

Or:

#if (SPICE_SERVER_VERSION >= 0x000b01) && (SPICE_PROTOCOL_VERSION >= ...)

cheers,
  Gerd

Strange, will resend.

So yet another place to remember to update the version number. But I
agree it's cleaner.

I don't get this. You mean to have add
#define QXL_HAS_IO_MONITORS_CONFIG_ASYNC bla
to spice-protocol?

Correct, the point was to make sure when I later removed only a part of
it it would show up as a single line removal. But sure, if you prefer it
this way.

No, to qemu, so QXL_HAS_IO_MONITORS_CONFIG_ASYNC is available no matter
what version spice-protocol is.

cheers,
