      drm/i915/gvt: handle fence reg access during GPU reset · d1be371d
      Zhao, Xinda authored
      Lots of reduntant log info will be printed out during GPU reset,
      including accessing untracked mmio register and fence register,
      variable disable_warn_untrack is added previously to handle the
      situation, but the accessing of fence register is ignored in the
      previously patch, so add it back.
      
      Besides, set the variable disable_warn_untrack to the defalut value
      after GPU reset is finished.

      drm/i915/gvt: introduced failsafe mode into vgpu · fd64be63
      Min He authored
      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 authored
      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:

      drm/i915/gvt: fix crash at function release_shadow_wa_ctx · 7e5f3d30
      Changbin Du authored
      In function dispatch_workload(), if it fail before calling
      intel_gvt_scan_and_shadow_wa_ctx(), the indirect ctx will
      not be shadowed so no cleaup need. wa_ctx->indirect_ctx.obj
      indicate whether indirect_ctx is shadowed. The obj is null
      if it is unshadowed.
