The gather filter is a feature present on Tegra124 and newer where the

This commit enables the gather filter on all supporting hardware.

TRM says that "Invalid Gbuffer cmd" interrupt would be raised when filtering
happens. Is that interrupt disabled by default or it would cause 'unhandled
interrupt'?
It's disabled by default. Jobs that are stopped by the filter are then
handled by the usual timeout mechanism.
