From cf1d06ac53a15b83c0a63225606cfe175e33a8a0 Mon Sep 17 00:00:00 2001 From: Andrzej Kacprowski Date: Tue, 11 Jun 2024 14:04:30 +0200 Subject: accel/ivpu: Increase autosuspend delay to 100ms on 40xx The new HW is more power efficient and there is no need to enter the D0i3/D3 so quickly. Increasing autosuspend delay reduces latency in certain usage scenarios.
