Current option of removing vGSI capability is global, which exposes vIOAPIC link for all ptdev even only one need this. This patch makes it as ptdev local option to lower the system level impact. To keep vGSI for MSI capable ptdev, just explicitly append ",keep_gsi" in option list, like "-s 14,passthru,0/e/0,keep_gsi" Signed-off-by: Edwin Zhai <edwin.zhai@intel.com> Acked-by: Anthony Xu <anthony.xu@intel.com>
