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 Signed-off-by: Min He <min.he@intel.com> Signed-off-by: Pei Zhang <pei.zhang@intel.com> Signed-off-by: Zhenyu Wang <zhenyuw@linux.intel.com> |
