From: John Harrison <john.c.harri...@intel.com>
ATS has lots of extra media engines. This series adds support for them.
Note, a recent GuC FW is required - 32.0.3 is known to be good.
Version 31.0.1 causes a hang when i915 initialised the fifth VCS
engine.
v2: Clean up the I915_MAX_ENGINES define. Make assumptions about ATS
engine counts. [Tvrtko Ursulin]
v3: Rebase to a new location within the internal history and add a
NOT_UPSTREAM patch to disable the extra engines if the GuC FW in use
is too old to support them. [Daniele].
v4: Tweaks to GuC FW test (for module param overrides) and to
interrupt enabling (to support fused parts). [Daniele]

+Subject: [PATCH] NOT_UPSTREAM: drm/i915: Disable extra engines on older GuC FW
+
+The current GuC FW release (31.0.1) dies when presented with too many
+media engines. The issue was fixed by 32.0.3 (which is the next FW the
+driver is intending to switch to). It is desirable to merge the the
+patches which allow use of the new engines before the new GuC FW
+patches can be merged. E.g. for running in non-GuC mode and/or running
+with a locally patched driver for the newer FW. Hence this patch
+disables the extra engines if the newer FW is not found.
+
+v2: Cope with GuC FWs loaded via the module param (by just ignoring it
+and warning the user). [Daniele]

+ definitions)
+
+ATS has lots of extra media engines. This patch adds the basic
+definitions for them.
+
+Also, add a sentinel to the engine id enum. That way there is no need
+to know which engine is the last in the list.
+
+v2: Clean up I915_MAX_ENGINES - it is now the sentinel enum value in
+the engine id list rather than a separate define in a separate header.

+Subject: [PATCH] drm/i915/selftests: Allow for larger engine counts
+
+Increasing the engine count causes a couple of local array variables
+to exceed the kernel stack limit. So make them dynamic allocations
+instead.
