Gentoo Overlay containing packages for the Raspberry Pi4 I have been unable to find in Portage Overlays or elsewhere. Testing and updating of these ebuilds is rather irregular.

There generally are two methods to install this overlay.

To install this overlay using app-portage/layman, run the following command

layman -o https://raw.githubusercontent.com/Jarodiv/rpi4-overlay/master/repositories.xml -f -a rpi4-overlay

More information on this can be found in the Gentoo Wiki.

To install this overlay as a local repository, create a file /etc/portage/repos.conf/rpi4-overlay.conf containing the following text:

[rpi4-overlay]
priority = 50
location = /var/db/repos/rpi4-overlay
sync-type = git
sync-uri = https://github.com/Jarodiv/rpi4-overlay.git
auto-sync = Yes

Then run emaint -r rpi4-overlay sync, Portage should now find and update the repository.

• sys-firmware/brcm43455-firmware upstream

  • Provides the firmware files for use with the RPi3 B+ / RPi 4 B's dual-band WiFi WiFi chip set (Cypress CYW43455). Also provides a newer copy of the uploadable file /lib/firmware/brcm/brcmfmac43455-sdio.bin. :warning: To avoid conflicts with the older version provided by sys-kernel/linux-firmware, you need to emerge that package with the Use flag savedconfig enabled, comment out or delete the line brcm/brcmfmac43455-sdio.bin in the file /etc/portage/savedconfig/sys-kernel/linux-firmware-<version> and re-emerge the package.

• sys-kernel/raspberrypi4-sources upstream

  • Provides the kernel sources for use with the RPi4 B (with make bcm2711_defconfig already being run)
