[PATCH v4 1/3] drm/i915/gt: Disable HW load balancing for CCS

2024-03-05 Thread Andi Shyti
The hardware should not dynamically balance the load between CCS engines. Wa_14019159160 recommends disabling it across all platforms. Fixes: d2eae8e98d59 ("drm/i915/dg2: Drop force_probe requirement") Signed-off-by: Andi Shyti Cc: Chris Wilson Cc: Joonas Lahtinen Cc: Matt Roper Cc: # v6.2+
