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". https://lists.nongnu.org/archive/html/qemu-devel/2015-01/msg02050.html 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 true 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 And note actually that option "-gfx_passthru" is just introduced to work for qemu-xen-traditional so we should get this away from libxl__build_device_model_args_new() in the case of qemu upstream. ---------------------------------------------------------------- Tiejun Chen (2): libxl: introduce libxl__is_igd_vga_passthru libxl: introduce gfx_passthru_kind tools/libxl/libxl_dm.c | 15 ++++- tools/libxl/libxl_internal.h | 2 + tools/libxl/libxl_pci.c | 124 +++++++++++++++++++++++++++++++++++ tools/libxl/libxl_types.idl | 6 ++ tools/libxl/xl_cmdimpl.c | 22 ++++++- 5 files changed, 164 insertions(+), 5 deletions(-) Thanks Tiejun
