bazzite-win3

windows 10 dual boot, bazzite os installation needs to create these partition by manually to install the os.

/boot/efi           efi partition 300MiB
/boot               ext4 partition 1GiB
mount point: /
format:      btrfs (subvolume)

mount point: /var

mount point: /var/home

Win3 Selinux set up to permissive:

$ sudo vim /etc/selinux/config

SELINUX=permissive

$ sudo systemctl reboot

win3 rotation:

win3 windows ntfs disk for sharing to bazzite os:

/dev/nvme0n1p5 is D drive steam libary, insert the last line to /etc/fstab

Create ~/local directory for mounting ntfs D drive;

$ mkdir ~/local

Create ~/share directory for using the new steam libary;

$ mkdir ~/share

Insert the last line to /etc/fstab;

$ sudo vim /etc/fstab

rpm installation for hibernate instead of sleep( needs reboot twice and it will create 32GiB swapfile for hibernate automatically ) :

$ sudo rpm-ostree install ostree-s4swap-20231112-1.fc39.x86_64.rpm
$ sudo systemctl reboot

rpm installation for intel cpu cpu_max_perf:

$ sudo rpm-ostree install intel_set_prefs-20231112-1.fc39.x86_64.rpm
$ sudo systemctl reboot

$ intel_set_prefs -read-all

$ intel_set_prefs -write-sensor cpu_max_perf 70

{"cpu_min_perf":"8","cpu_max_perf":"70","cpu_turbo":"true","gpu_min_freq":"100","gpu_max_freq":"1300","gpu_min_limit":"350","gpu_max_limit":"1300","gpu_boost_freq":"1300","gpu_cur_freq":"350","cpu_governor":"powersave","intel_rapl_short":"40","intel_rapl_long":"162"}

Use systemd daemon to lock cpu_max_perf to 70%:

$ sudo vim /etc/systemd/system/set_prefs.service

Description=Set Performance Script
Requires=local-fs.target
After=local-fs.target


[Service]

ExecStart=/usr/bin/intel_set_prefs -write-sensor cpu_max_perf 70 || true
RemainAfterExit=no

[Install]
WantedBy=default.target

sudo systemctl daemon-reload
sudo systemctl enable set_prefs.service
sudo systemctl start set_prefs.service

Use decky terminal plugin to adjust cpu max perf

Change Default shell to /bin/bash

echo "alias i='/usr/bin/intel_set_prefs -write-sensor cpu_max_perf'" >> ~/.bashrc
source ~/.bashrc

$ i 58
{"cpu_max_perf":"58"}

Use steam-patch-intel (latest client doesn't work), steam support 3~10 tdp to change cpu_max_perf 30%~100% (need 2 rpms packages intel_set_prefs & steam-patch-intel):

$ sudo rpm-ostree install intel_set_prefs-20231112-1.fc39.x86_64.rpm steam-patch-intel-20240216-1.fc39.x86_64.rpm
$ sudo systemctl reboot

$ sudo systemctl enable steam-patch-intel@deck
$ sudo systemctl start steam-patch-intel@deck
