Fitlet: Installing Linux Mint 17.2
From fit-PC wiki
Outdated. See AMD: Installing Linux Mint 19
Prepare installation media
- A USB DVD-ROM drive or a USB Flash drive of at least 2GB should be used as installation media
- Download Linux Mint 17.2 "Rafaela" - Cinnamon (64-bit)"
- For installation with a USB DVD-ROM - flash the downloaded image directly onto a DVD
- For installation with a USB Flash drive, please follow How to install Linux Mint via USB tutorial
Base installation of Linux Mint
- Follow the standard Linux Mint installation procedure - choose timezone, partitions, username, password etc.
- Disconnect the installation media and reboot.
- Login using previously selected username and password.
ATI Catalyst video driver
- fglrx is a proprietary ATI Catalyst video driver that provides XvBA (X-video Bitstream Acceleration) support.
- WARNING!!! fglrx driver has been updated on 2015-05-19, from version 13.350 to 15.200. There is a bug or some incompatibility in the new package. Please blacklist new version until Ubuntu or ATI will release the fix. Create file /etc/apt/preferences.d/fglrx.13.350.pref
Package: fglrx* Pin: release a=trusty Pin-Priority: 1001
- Install fglrx driver and other required utilities with the command below:
$ sudo apt-get update $ sudo apt-get install fglrx-updates fglrx-amdcccle-updates xvba-va-driver vainfo
- Note: system reboot is required after the installation of the fglrx driver.
Kodi and VLC
- Kodi (formerly known as XBMC) and VLC are well known free and open-source multimedia players
- Both of them use GPU accelerated video decoding and give excellent playback quality
- Both of them compatible with the most popular video formats
$ sudo add-apt-repository ppa:team-xbmc/ppa $ sudo apt-get update $ sudo apt-get install kodi vlc
- Kodi will support GPU accelerated video decoding out of the box
- In VLC you need to check Tools->Preferences->Input and Codecs->Use GPU accelerated decoding checkbox to take advantage of GPU accelerated video decoding
- Install tools for monitoring CPU and storage temperature
$ sudo apt-get install lm-sensors hddtemp
$ sensors k10temp-pci-00c3 Adapter: PCI adapter temp1: +60.9°C (high = +70.0°C) (crit = +105.0°C, hyst = +104.0°C)
$ sudo hddtemp /dev/sda /dev/sda: SanDisk SD6SF1M064G: 42°C
Aggressive Link Power Management (ALPM)
- It's a mechanism where a SATA controller can put the disk into a very low power mode during periods of zero I/O activity and into an active power state when work needs to be done. Tests show that this can save some power and decrease mSATA average temperature.
- Create text file /etc/pm/power.d/sata_alpm
#!/bin/sh for i in /sys/class/scsi_host/host*/link_power_management_policy; do echo min_power > $i done
- Make it executable
$ sudo chmod +x /etc/pm/power.d/sata_alpm
- Reboot, check that SATA power management policy has been changed
$ cat /sys/class/scsi_host/host*/link_power_management_policy min_power min_power
- NOTE! Not supported in mainline Linux kernel yet. Linux Kernel 3.16 for Fitlet should be installed to make this feature work
- The AMD FCH (Fusion Controller Hub) supports a user configurable watchdog
- Once the watchdog is enabled the system restarts once the timeout period elapses, in order to prevent it the user needs to either feed the watchdog or to disable it
$ sudo apt-get install watchdog
- Uncomment watchdog-device line in /etc/watchdog.conf
watchdog-device = /dev/watchdog
- Set responsible kernel module to sp5100_tco in /etc/default/watchdog
- By default the timeout value is 60 sec and the watchdog deamon feeds the watchdog every 10 sec
- As example you can simulate kernel panic (as root user):
$ echo c > /proc/sysrq-trigger
- As a result, the watchdog is not fed and the system will reboot after 60 sec
- NOTE! Not supported in mainline Linux kernel. Linux Kernel 3.16 for Fitlet should be installed to make this feature work
- GPIO interface on fitlet consists of 9 GPIOs provided by AMD FCH (Fusion Controller Hub)
- The responsible kernel module is gpio_fch
- The kernel module uses the following pin naming convention:
|Pin Number||Color Code||GPIO name||Power domain||HW source||Notes|
- The GPIO sysfs interface allows users to manipulate any GPIO from userspace dynamically.
- A basic example of GPIO P-1 (Brown) usage (as root user):
$ modprobe fch_gpio $ echo 89 > /sys/class/gpio/export $ echo out > /sys/class/gpio/gpio89/direction $ echo 1 > /sys/class/gpio/gpio89/value ## at this point voltage measuring on P-1 (Brown) should give 3.3V $ echo 0 > /sys/class/gpio/gpio89/value ## at this point voltage measuring on P-1 (Brown) should give 0.0V $ echo 89 > /sys/class/gpio/unexport
- The GPIO framework and GPIO sysfs interface are documented in https://www.kernel.org/doc/Documentation/gpio/gpio.txt
