Subject: [Intel-gfx] [PATCH 00/18] Non-interface changing GuC CTBs updates
Date: Tue, 25 May 2021 23:42:19 -0700	[thread overview]
Message-ID: <20210526064237.77853-1-matthew.brost@intel.com> (raw)

As discussed in [1] we are breaking that large series into a several
smaller ones. This series is the non-interface changing part of step #2
- it makes all the changes needed before updating the GuC firwmare to a
new version without breaking any old interfaces.

A follow on series will be squashed into a single patch that updates the
GuC firmware + the required interface changes.

Patch number #13 needs an Ack from Michal Wajdeczko.
Patch number #6, #15 need reviews.

v2: Fix some checkpatch warnings, add patch number #6 to address CI
failure [2] in first rev
