原来在10.3中可以正常用SR-IOV虚拟显卡，入正升级到12.0，无论怎么都无法使用SR-IOV虚拟出显卡了。 这是I915信息： root@dy:~# dmesg | grep i915 [ 22.728139] i915 0000:00:02.0: [drm] Incompatible option enable_guc=7 - undocumented flag [ 22.728906] i915 0000:00:02.0: [drm] VT-d active for gfx access [ 22.729348] i915 0000:00:02.0: vgaarb: deactivate vga console [ 22.729384] i915 0000:00:02.0: [drm] Using Transparent Hugepages [ 22.729957] i915 0000:00:02.0: vgaarb: changed VGA decodes: olddecodes=io+mem,decodes=io+mem:owns=io+mem [ 22.731957] mei_hdcp 0000:00:16.0-b638ab7e-94e2-4ea2-a552-d1c54b627f04: bound 0000:00:02.0 (ops i915_hdcp_component_ops [i915]) [ 22.732706] i915 0000:00:02.0: [drm] Finished loading DMC firmware i915/adls_dmc_ver2_01.bin (v2.1) [ 22.839870] i915 0000:00:02.0: [drm] GuC firmware i915/tgl_guc_70.bin version 70.5.1 [ 22.839875] i915 0000:00:02.0: [drm] HuC firmware i915/tgl_huc.bin version 7.9.3 [ 22.842410] i915 0000:00:02.0: [drm] HuC authenticated [ 22.842974] i915 0000:00:02.0: [drm] GuC submission enabled [ 22.842976] i915 0000:00:02.0: [drm] GuC SLPC enabled [ 22.843271] i915 0000:00:02.0: [drm] GuC RC: enabled [ 22.843765] mei_pxp 0000:00:16.0-fbf6fcf1-96cf-4e2e-a6a6-1bab8cbe36b1: bound 0000:00:02.0 (ops i915_pxp_tee_component_ops [i915]) [ 22.843861] i915 0000:00:02.0: [drm] Protected Xe Path (PXP) protected content support initialized [ 22.869993] [drm] Initialized i915 1.6.0 20201103 for 0000:00:02.0 on minor 0 [ 22.886522] fbcon: i915drmfb (fb0) is primary device [ 22.968201] i915 0000:00:02.0: [drm] fb0: i915drmfb frame buffer device [ 93.256787] i915 0000:00:02.0: driver does not support SR-IOV configuration via sysfs [ 160.493863] i915 0000:00:02.0: driver does not support SR-IOV configuration via sysfs [ 167.306557] i915 0000:00:02.0: driver does not support SR-IOV configuration via sysfs [ 173.305513] i915 0000:00:02.0: driver does not support SR-IOV configuration via sysfs 请大佬指点一下。谢谢！
