Instalar Gentoo con Phosh y Systemd en Pinephone – Aprendiz de Ingeniero en Sistemas de Información

Pinephone es un smartphone interesante para probar diferentes sistemas operativos. Un reto interesante es instalar Gentoo, una distribución de GNU/Linux conocida por su curva de aprendizaje. En este tutorial se da por hecho que el lector tiene conocimientos sobre GNU/Linux y ha utilizado Gentoo por lo menos una vez. En mi caso voy a utilizar Qemu para realizar el procedimiento de instalación, aprovechando tamién lo que hice en este artículo

Esta guia sirve como complemento al manual oficial de Gentoo, por lo que aqui se muestran los pasos especificos para Pinephone

Actualmente es posible utilizar pipewire como servidor de audio, aunque en caso de tener problemas de compatibilidad con dispositivos de audio bluetooth es posible volver a pulseaudio

En mi caso el archivo make.conf de portage quedó así

COMMON_FLAGS="-march=armv8-a+crypto+crc -mtune=cortex-a53 -O2 -pipe -fomit-frame-pointer -ftree-vectorize"
CFLAGFS="${COMMON_FLAGS}"
CXXFLAGS="${COMMON_FLAGS}"
FCFLAGS="${COMMON_FLAGS}"
FFLAGS="${COMMON_FLAGS}"
MAKEOPTS="-j5"

Los parámetros que elegi en COMMON_FLAGS son importantes si se va a compilar los paquetes en un dispositivo diferente al pinephone, los paquetes se optimizaran para el pinephone y no para el hardware que ejecuta el compilador. El controlador de video elegido es el requerido para la gpu del pinephone. Las etiquetas USE son elegidas para mi caso de uso específico

Es necesario elegir un perfil de sistema con systemd que sea apto para Gnome

Para poder agregar repositorios de terceros es necesario instalar eselect-repository

emerge --ask app-eselect/eselect-repository

Para poder instalar Phosh es necesario el repositorio gjdwebserver

eselect repository add gjdwebserver git https://git.gjdwebserver.nl/gjdwebserver/gjdwebserver-overlay.git

En el repositorio Layla hay algunos paquetes interesantes

eselect repository add laylarepo git https://git.asgardius.company/asgardius/laylarepo.git

Algunos paquetes dependen de otros que se encuentran en el repositorio Guru

eselect repository enable guru

Elegi los siguientes servidores de paquetes binarios

[gentoo]
priority = 1
sync-uri = https://elda.asgardius.company/gentoo/releases/arm64/binpackages/23.0/arm64
location = /var/cache/binhost/gentoo
verify-signature = true

[gjdwebserver]
priority = 1
sync-uri = https://distfiles.gjdwebserver.nl/
location = /var/cache/binhost/gjdwebserver
verify-signature = false

[layla-bin]
sync-uri = https://layla-bin.momo.asgardius.company/arm64
priority = 10

Instalaremos los siguientes paquetes para tener la interfaz de usuario phosh

emerge --ask gui-wm/phosh net-misc/eg25-manager x11-misc/stevia net-im/chatty net-voip/gnome-calls gnome-extra/gnome-contacts x11-misc/phosh-mobile-settings x11-misc/sddm net-misc/networkmanager

Habilitamos NetworkManager

systemctl enable NetworkManager
systemctl enable ModemManager

Configuramos SDDM

nano /etc/sddm.conf.d/01gentoo.conf

Agregamos lo siguiente

[Autologin]
User=<Usuario>
Session=phosh

Habilitamos SDDM

systemctl enable sddm

En caso de que no funcione el audio, será necesario corregir los perfiles de ALSA. Editamos primero el siguiente archivo

nano /usr/share/alsa/ucm2/Allwinner/A64/PinePhone/PinePhone.conf

Colocamos lo siguiente

Configuramos systemd resolved y eg25-manager (para poder utilizar el modem del pinephone)

ln -sf ../run/systemd/resolve/stub-resolv.conf /etc/resolv.conf
systemctl enable systemd-resolved.service
systemctl enable eg25-manager.service
