Missing Firmware

Not all needed device drivers might be included in the standard installation packages. After booting the new system check the syslog and look for errors and warnings.

  # cat /var/log/syslog

You can download tar.gz from https://git.kernel.org/pub/scm/linux/kernel/git/firmware/linux-firmware.git. Extract the kbl_dmc_ver1_04.bin from the correct version of the installation.

 # cp kbl_dmc_ver1_04.bin /lib/firmware/i915
 # reboot
After rebooting the result should look like:

SMART

Install smartmon tools and check the status:

# apt-get install smartmontools
# smartctl -a /dev/sda

Power Saving

For ASPM enabling the following lines are added to the powersave service. However no noticable difference are measured:

# Enable L1 and L0s on PCIe Intel Bridge and Realtek network adapter
# Does not seem to differ anything
setpci -s 00:1c.0 0x50.B=0x43
setpci -s 01:00.0 0x80.B=0x43

Sensors

# apt-get install lm-sensors

The following NEW packages will be installed: libsensors4 lm-sensors

# sensors-detect

---------------------------------------------------------------
	Trying family `VIA/Winbond/Nuvoton/Fintek'... Yes
	Found unknown chip with ID 0xd352

The chip is an exclusive for MSI, and Nuvoton can not give me the datasheet because of an NDA with MSI. The chip looks pretty similar to NCT6793D.

modprobe nct6775 force_id=0xd120

Now “sensors” will show more info.

To load everything that is needed, add this to /etc/modules:

# nano /etc/modules

#----cut here----
# Chip drivers
coretemp
#----cut here----

Now “sensors” will show more info:

 
# sensors
