Crosshair VI Hero WiFi AC (X370) Support
darcagn opened this issue · comments
board_name: ROG CROSSHAIR VI HERO (WI-FI AC)
mutex name: \AMW0.ASMX (same as others)
This board is being used in an Ubuntu LTS server with an older 5.4 kernel -- it was unable to compile at first because linux/dev_printk.h and linux/units.h weren't found. I removed the includes for those two header files and it seems to compile and work just fine, but I am unsure if functionality has been affected.
These sensors work just fine and match the same output from asus-wmi-sensors:
SENSOR_SET_TEMP_CHIPSET_CPU_MB | SENSOR_TEMP_T_SENSOR | SENSOR_CURR_CPU
SENSOR_FAN_CPU_OPT_X470 is the same situation as the X470 board, CPU_OPT is at 0x00bc (in place of Water_Flow for 500-series).
I plugged in fans/probes to the other sensor connectors and could not get a reading from any other sensor, including CPU voltage. I didn't get to poke around the registers with this board though, so there may be other undiscovered sensors exposed in the EC.
I have attached the DSDT file for this board if it helps.

Now, what does REC2() do?
Recompiling and testing with these new values:
- SB 1.05V Voltage shows up, but it's only showing about 338mV when asus-wmi-sensors shows 1.06V. I don't know what the *=0x0C35 means, though.
- Chipset Temp, Tsensor 1 Temp, CPU VRM Temp, CPU VRM Current, and CPU OPT values are working properly and agree with asus-wmi-sensors.
- The three sensors showing REC2 don't work, I guess something else has to be changed.
Now, what does REC2() do?
Here is its code:
Method (REC2, 2, Serialized)
{
IBFY ()
EC6C = 0x91
IBFY ()
EC68 = 0xFF
IBFY ()
EC68 = Arg0
IBFY ()
EC6C = 0x90
IBFY ()
EC68 = Arg1
OBFY ()
Local0 = EC68 /* \AMW0.EC68 */
Return (Local0)
}
Looks like it reads from a EC controller via ports 0x68 and 0x6c, but what are constants 0x91 and 0x90 for?
- SB 1.05V Voltage shows up, but it's only showing about 338mV when asus-wmi-sensors shows 1.06V. I don't know what the *=0x0C35 means, though.
I guess it is a conversion factor to volts. 0x0C35 (=3125) * 0.338 = 1.056, which is pretty close to 1.06.
- Chipset Temp, Tsensor 1 Temp, CPU VRM Temp, CPU VRM Current, and CPU OPT values are working properly and agree with asus-wmi-sensors.
Great!
- The three sensors showing REC2 don't work, I guess something else has to be changed.
They need to be read via other EC ports (see REC2() above).
I guess it is a conversion factor to volts. 0x0C35 (=3125) * 0.338 = 1.056, which is pretty close to 1.06.
Sorry, to µV, of course: 3125 * 338 * 1e-6 = 1.05625
