if a context is a restore inhibit context, gfx hw only load the first page for ring context, so we only need to copy from guest the 1 page too. v3: use "return" instead of "goto" for inhibit case. (zhenyu wang) v2: move judgement of restore inhibit to a macro in mmio_context.h Signed-off-by: Zhao Yan <yan.y.zhao@intel.com> Acked-by: Hang Yuan <hang.yuan@linux.intel.com> Signed-off-by: Zhenyu Wang <zhenyuw@linux.intel.com>
