    How do you capture the state to replay it? Is capturing low-overhead enough that end user machines could record to a circular buffer in /tmp, without disrupting normal usage?

      Can this be done in AMD GPUs too?

        This is sorely needed for AMD gpus as well.

            At a quick glance, it looks like they provide a mechanism to dump the current command buffers and mapped memory on the GPU which can then be replayed later. Looks similar to apitrace, but lower level. Something similar could be done for any GPU vendor.

              Any plans to make it happen?
