From 02fbdc6a47ba6d3ede3c5bb639035f3978ba5a5a Mon Sep 17 00:00:00 2001 From: John Audia Date: Sun, 23 Jan 2022 04:42:41 -0500 Subject: [PATCH] bcm27xx: update distroconfig.txt for faster RPi4 Newer RPi 4 Rev 6 (8 GB models and recent 2 GB / 4 GB models) ship with the so-called C0 processor which can run turbo mode at 1.8 GHz max rather than 1.5 GHz gracefully. Add 'arm_boost=1' to pi4 section of to enable. Note that this setting has no effect on older chips; they continue with their 1.5 GHz max unless users overclock them.
