Save RING_HEAD into vgpu reg when vgpu switched out and report it's value back to guest. v6: addressed comment for ring head wrap count support. (Zhenyu) v5: ring head wrap count support. v4: updated HEAD/TAIL with guest value, not host value. (Yan Zhao) v3: save RING HEAD/TAIL vgpu reg in save_ring_hw_state. (Zhenyu Wang) v2: save RING_TAIL as well during vgpu mmio switch to meet ring_is_idle condition. (Fred Gao) v1: based on input from Weinan. (Weinan Li) [zhenyuw: Include this fix for possible future guest kernel that would utilize RING_HEAD for hangcheck.] Reviewed-by: Zhenyu Wang <zhenyuw@linux.intel.com> Signed-off-by: Xiaolin Zhang <xiaolin.zhang@intel.com> Signed-off-by: Zhenyu Wang <zhenyuw@linux.intel.com>
