Be sure to test the performance - if the numbers don't match up (for instance in the LINPACK benchmark), something is very wrong.

More recent, unofficial kernel releases for the Raspberry Pi might be found at Chris Boot's repository:.

The smallest amount that can be set is 16 MB, default is 64 MB

If more RAM is required for Linux, set the option gpu_mem in config.txt.

A fallback incremental clock can be archived by the swclock service (replaces the hwclock service). Use the ntp-client service to set the correct system time on boot. There is no hardware RTC on the Raspberry Pi.If emerge will be running on the Raspberry Pi, putting /usr/portage on squashfs will speed up things dramatically. Storage is rather slow, even with the couple of compatible SDHC class 10 cards.To enable VideoCore4 GPU acceleration on RPi device add following to /boot/config.txt:įor more info refer to Raspberry Pi VideoCore4 page. The project's GitHub page additionally contains instructions for setting up crossdev and distcc to build for the 64-bit RPi3 / RPi4.

The image contains a full Portage tree (and /etc/portage/ set) so that you can run emerge operations immediately.

Accelerated VC4 graphics, via vc4-fkms-v3d / vc4 kernel module / Mesa.

ALSA sound playback, via headphone jack and HDMI.

Access to the camera module (if fitted) and h/w video codecs, via V4L2-M2M / MMAL.

The Pi's onboard Ethernet, Wi-Fi, and Bluetooth adapters.Leveraging recently improved 64-bit support in the official Raspberry Pi kernel tree, the image supports: Those interested in trying 64-bit Gentoo on their RPi3 (model B or B+) or RPi4 (model B) may wish to check out the (unofficial) bootable image available here, from which the above screenshot has been taken (see also this forum thread).
