Yup, that's a bug. Can you send a ppgtt = rq->ctx->ppgtt ?: &rq->i915->mm.aliasing_ppgtt; One day we will bite the bullet and set ctx->ppgtt to be the aliasing_ppgtt (and maybe even fix it so that we can global_gtt as appropriate), and then just fix up the more unusual case in execbuf to bind using vm = global_gtt instead (if aliasing). -Chris
