EasyOS 64-bit running faster in Pi4

January 10, 2021 — BarryK

I posted today about EasyOS booting up on the Raspberry Pi 4, getting a desktop and sound and wifi working, but everything running incredibly slow:

It has defaulted to the "powersave" governor, and the CPUs are running at 600MHz. I bumped that up:

# cat /sys/devices/system/cpu/cpufreq/policy0/cpuinfo_cur_freq
# echo performance > /sys/devices/system/cpu/cpufreq/policy0/scaling_governor
# cat /sys/devices/system/cpu/cpufreq/policy0/cpuinfo_cur_freq

An improvement, but everything still very sluggish. Then I remembered something about VideoCore graphics on the Pi3, and in file 'config.txt' in the boot partition, I commented-out the line "dtoverlay=vc4-fkms-v3d":

# Enable VC4 Graphics

# Force arm in 64bit mode. See:

#Enable the onboard ALSA audio

#load initrd into ram immediately after kernel
initramfs initrd followkernel

The desktop is now quite snappy. haven't tried 'hardinfo' speed tests yet! I suspect they will still be abysmally slow.
