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 ---------------------------------------------------------------- Tiejun Chen (2): libxl: introduce libxl__is_igd_vga_passthru libxl: introduce gfx_passthru_kind tools/libxl/libxl_dm.c | 13 +++++++++++++ tools/libxl/libxl_internal.h | 2 ++ tools/libxl/libxl_pci.c | 124 ++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++ tools/libxl/libxl_types.idl | 6 ++++++ tools/libxl/xl_cmdimpl.c | 19 +++++++++++++++++-- 5 files changed, 162 insertions(+), 2 deletions(-) Thanks Tiejun
