      drm/i915/gvt: introduced failsafe mode into vgpu · fd64be63
      Min He 提交于
      New failsafe mode is introduced, when we detect guest not supporting
      GVT-g.
      In failsafe mode, we will ignore all the MMIO and cfg space read/write
      from guest.
      
      This patch can fix the issue that when guest kernel or graphics driver
      version is too low, there will be a lot of kernel traces in host.
      
      V5: rebased onto latest gvt-staging
      V4: changed coding style by Zhenyu and Ping's advice
      V3: modified coding style and error messages according to Zhenyu's comment
      V2: 1) implemented MMIO/GTT/WP pages read/write logic; 2) used a unified
      function to enter failsafe mode

      drm/i915/gvt: Fix check error on opregion.c · f655e67a
      Zhenyu Wang 提交于
      As we switched to memremap for opregion, shouldn't use any __iomem
      for that, and move to use memcpy instead.
      
      This fixed static check errors for:

      not be shadowed so no cleaup need. wa_ctx->indirect_ctx.obj
