Subject: [i-g-t, v6, 1/2] Revert "tests/kms_vrr: Start virtual RR test above midpoint to avoid mode fallback"
Date: Fri, 15 May 2026 06:32:50 +0000	[thread overview]
Message-ID: <20260515063251.2239524-2-shawn.c.lee@intel.com> (raw)
In-Reply-To: <20260515063251.2239524-1-shawn.c.lee@intel.com>

This reverts commit 862eb176244feac8ee711f381fe1be1fdc6a7ede.

The following patch will do full range testing. So no need to start at midpoint.
