[igt-dev] [PATCH i-g-t v2 00/11] Resurrect GuC Relay Logging

[Alan Previn <alan.previn.teres.alexis@intel.com>]

This series brings GuC relay logging back to life by
re-aligning the (previously implicit, now query-able)
guc-log-relay subbuffer-specs, debugfs file handle names
and usages between intel_guc_logger tool and i915.

This series depends on fixes and updates on the
kernel side via this series:
https://patchwork.freedesktop.org/series/103767/

Changes from prio revs:
   v1: - With MTL and multi-tile, add support for GT-ID
         selection for GuC logging.
       - Add new design changes to flusher thread to do
         decoding of the GuC log buffer header data and
         unwrap all head-->tail regions into a linear
         sequence so we can concatenate the GuC log outoput
         file to make it look like a single large contiguous
         GuC Log buffer (as it it came direct from memory).
         This was a design miss from original code and is
         needed to ensure internal tools can decode the logs.
