[Xen-devel] [PATCH 0/2] libxl: try to support IGD passthrough for qemu upstream



When we're working to support IGD GFX passthrough with qemu
upstream, instead of "-gfx_passthru" we'd like to make that
a machine option, "-machine xxx,igd-passthru=on". This need
to bring a change on tool side.

After a discussion with Campbell, we'd like to construct a table to record
all IGD devices we can support. If we hit that table, we should pass that
option. And so we also introduce a new field of type, 'gfx_passthru_kind',
to cooperate with 'gfx_passthru' to cover all scenarios like this,

    gfx_passthru = 0    => sets build_info.u.gfx_passthru to false
    gfx_passthru = 1    => sets build_info.u.gfx_passthru to false and
                           build_info.u.gfx_passthru_kind to DEFAULT
    gfx_passthru = "igd"    => sets build_info.u.gfx_passthru to false
                               and build_info.u.gfx_passthru_kind to IGD
