(In reply to comment #2) > To confirm the bisect, please try i915.enable_ppgtt=1 I have tried this "i915.enable_ppgtt=1",it can works well. Created attachment 106029 [details]

From Haswell only, you are able to select the security bit separate from the address space - and we always requested to use ppgtt. This breaks the golden render state batch execution with full-ppgtt as that is only present in the global GTT and more generally any secure batch that is not colocated in the ppgtt and ggtt. So we need to disable the use of the ppgtt selector bit for secure batches, or else we hang immediately upon boot and thence after every GPU reset... v2: Only HSW differentiates between secure dispatch and ggtt, so simply ignore the differentiation and always use secure==ggtt.
