ACPI INT340E PTID device

ACPI INT340E PTID device

[Armin Wolf]

Hello,

a user has asked if the ACPI INT340E device could be supported. Its seems that this device exposes
thermal and power sensors to the operating system, plus some general purpose "OSD" sensors.

The device is already supported by the Hackintosh community, see here:
https://github.com/RehabMan/OS-X-FakeSMC-kozlek/blob/master/ACPISensors/PTIDSensors.cpp

Back in 2014, the INT340E device was mentioned in message "1408622934.3315.8.camel@rzhang1-toshiba" as:

	The PTID device has _CID PNP0C02, but it is also represents an
    	INT340E device, there is a platform bus driver for this device
    	which will be introduced by myself soon.

Before developing a new driver for this device, i wanted to ask what happened to the driver mentioned
in this email? I am willing to do the testing, upstreaming and maintenance if necessary.

Thanks,
Armin Wolf

What does this device bring to the user?

Hmm, I don't know what this device really means. At least it is not
related with the other INT340X devices.

Interesting, I cannot recall what happened, maybe that device ID is
deprecated later.

CC srinivas, and we will make clear what it does before doing anything.

He wants to be able to monitor the fan speed on his MSI GF63-12VF, see
https://github.com/lm-sensors/lm-sensors/issues/475 for details.

Thanks,

it would be helpful if Intel could provide some documentation on how to use this
device (ACPI control methods, etc).

Hi, Armin,

This device is deprecated. There is no guarantee that this device will
exist and function in current and future devices.
I don't have any plan to support this device and there is no document
about it.

thanks,
