      drm/i915/guc: Update to GuC version 70.1.1 · 2584b354
      John Harrison authored
      The latest GuC firmware drops the context descriptor pool in favour of
      passing all creation data in the create H2G. It also greatly simplifies
      the work queue and removes the process descriptor used for multi-LRC
      submission. So, remove all mention of LRC and process descriptors and
      update the registration code accordingly.
      
      Unfortunately, the new API also removes the ability to set default
      values for the scheduling policies at context registration time.
      Instead, a follow up H2G must be sent. The individual scheduling
      policy update H2G commands are also dropped in favour of a single KLV
      based H2G. So, change the update wrappers accordingly and call this
      during context registration..
      
      Of course, this second H2G per registration might fail due to being
      backed up. The registration code has a complicated state machine to
      cope with the actual registration call failing. However, if that works
      then there is no support for unwinding if a further call should fail.
      Unwinding would require sending a H2G to de-register - but that can't
      be done because the CTB is already backed up.
      
      So instead, add a new flag to say whether the context has a pending
      policy update. This is set if the policy H2G fails at registration
      time. The submission code checks for this flag and retries the policy
      update if set. If that call fails, the submission path early exists
      with a retry error. This is something that is already supported for
      other reasons.

       "Here are two small driver core changes for 5.18-rc2.
      
        They are the final bits in the removal of the default_attrs field in

        changes to do this came in through different development trees, and
        then one new user snuck in. So this series has two changes:
      
         - removal of the default_attrs field in the powerpc/pseries/vas code.
      
           The change has been acked by the PPC maintainers to come through
           this tree
      
         - removal of default_attrs from struct kobj_type now that all
           in-kernel users are removed.
      
           This cleans up the kobject code a little bit and removes some
           duplicated functionality that confused people (now there is only
           one way to do default groups)
