List of parameters
| Location | /sys/devices/platform/msi-ec/fw_version |
| Access | Read |
| Valid values | a 12 character long string |
| EC address | [0xa0..0xac) (12 bytes) |
This entry reports the version of the EC firmware. Not to be confused with the BIOS firmware version.
| Location | /sys/devices/platform/msi-ec/fw_version |
| Access | Read |
| Valid values | a 19 character long string |
| EC address | [0xac..0xbc) (16 bytes) |
This entry reports the release date and time of the EC firmware.
| Location | /sys/devices/platform/msi-ec/webcam |
| Access | Read, Write |
| Valid values | on, off |
| Possible EC addresses | 0x2e |
This entry enables/disables the integrated webcam (same way the keyboard button does it)
| Location | /sys/devices/platform/msi-ec/webcam_block |
| Access | Read, Write |
| Valid values | on, off |
| Possible EC addresses | 0x2f |
This parameter disables the integrated webcam and blocks it from being enabled by a keyboard button. on means the webcam is blocked
| Location |
/sys/devices/platform/msi-ec/fn_key /sys/devices/platform/msi-ec/win_key
|
| Access | Read, Write |
| Valid values | left, right |
| Possible EC addresses | 0xbf, 0xe8 |
This entry allows swapping the function key and the windows key
| Location | /sys/devices/platform/msi-ec/cooler_boost |
| Access | Read, Write |
| Valid values | on, off |
| Possible EC addresses | 0x98 |
This entry enables the cooler boost function. It improves the laptop cooling by boosting the fan speed.
The EC address seems to be universal ([0x98], bit 7), at least across the models supported by this driver.
| Location | (1) /sys/devices/platform/msi-ec/shift_mode (2) /sys/devices/platform/msi-ec/available_shift_modes
|
| Access | (1) Read, Write (2) Read |
| Valid values | unspecified (read-only), eco, comfort, sport, turbo |
| Possible EC addresses | 0xf2, 0xd2 |
This parameter represents the performance modes. available_shift_modes reports the available modes.
Originally this was the only parameter known to be related to the "Shift Mode" parameter of the MSI Dragon Center, thus the name. Now we know another one (see Super Battery) but don't have enough info to properly rename it.
Reference EC values:
| mode | value |
|---|---|
| unspecified | 0x80 |
| eco | 0xc2 |
| comfort | 0xc1 |
| sport | 0xc0 |
| turbo | 0xc4 |
| Location | /sys/devices/platform/msi-ec/super_battery |
| Access | Read, Write |
| Valid values | - |
| Possible EC addresses | 0xd5, 0xeb, 0xe5 |
Warning: this parameter is WIP
This entry represents the performance modes (different from the Shift Mode).
The parameter changes with the Shift Mode of the MSI Dragon Center. Originally we associated it only with the "super battery" shift mode, thus the name.
| Location | (1) /sys/devices/platform/msi-ec/fan_mode (2) /sys/devices/platform/msi-ec/available_fan_modes
|
| Access | (1) Read, Write (2) Read |
| Valid values | auto, silent, basic, advanced |
| Possible EC addresses | 0xf4, 0xd4 |
The fan_mode parameter controls the fan mode. It provides a set of profiles for adjusting the fan speed under specific criteria. available_fan_modes reports the available modes.
Supported modes are:
-
auto: the fan speed is controlled automatically -
silent: very low fan speed to keep the fan quiet -
basic: custom constant fan speed -
advanced: custom fan curve
Reference EC values:
| mode | values |
|---|---|
| auto | 0x0d, 0x0f |
| silent | 0x1d, 0x1f |
| basic | 0x4d, 0x4f |
| advanced | 0x8d, 0x8f |
| Location | (1) /sys/class/power_supply/<supply_name>/charge_control_start_threshold (2) /sys/class/power_supply/<supply_name>/charge_control_end_threshold
|
| Access | Read, Write |
| Valid values | 0 - 100 (percent) |
| Possible EC addresses | 0xef, 0xd7 |
These parameters control charging thresholds. Battery stops charging when it reaches the end threshold and starts charging when it reaches the start threshold. Thresholds are always 10% apart
