+Subject: drm/amd/display: Temporarily disable hostvm on DCN31
+
+From: Aurabindo Pillai <aurabindo.pillai@amd.com>
+
+commit ba93dddfc92084a1e28ea447ec4f8315f3d8d3fd upstream.
+
+With HostVM enabled, DCN31 fails to pass validation for 3x4k60. Some Linux
+userspace does not downgrade one of the monitors to 4k30, and the result
+is that the monitor does not light up. Disable it until the bandwidth
+calculation failure is resolved.
