Hi Chris:
Thanks for the reply! :P Have you also fixed here with your new ideas?
in intel_lrc:
static u64 execlists_update_context(struct drm_i915_gem_request *rq)
{
struct intel_context *ce = &rq->ctx->engine[rq->engine->id];
struct i915_hw_ppgtt *ppgtt = rq->ctx->ppgtt; // ----> check
if we should get ppgtt from dev_priv->mm.aliasing_ppgtt.
u32 *reg_state = ce->lrc_reg_state;
reg_state[CTX_RING_TAIL+1] = rq->tail;

That is incorrect, they are loaded into the context image before
submission. If you want to make sure they are unchanging so that
lite-restore under g-GVT works, that is another matter.
