Kernel driver for Intel Sunrise Point-H PMC

[brundage]

I'm on kernel 4.14.65-gentoo and am having a hard time finding the driver for this one last piece of hardware.

Motherboard: ASUS H170 PRO GAMING

Anyone know if this is supported in 4.14 and where to find the CONFIG?

intel_pmc_core

device drivers -> x86 platform specific device drivers -> intel pmc core driver

odd, i have that driver enabled on my laptop but it doesn't seem to do anything... and lspci doesn't show as it being used.

I have rev 21 on my acer laptop and it shows up as being installed and used. as for what it does *shrugs*

intel_pmc_core

device drivers -> x86 platform specific device drivers -> intel pmc core driver

I have this enabled already and the system doesn't report it in use for Sunrise Point-H SMBus.

Then I don't know what to tell you, I'm kernel 4.14.62 and works, though lspci says mine is (rev 21), maybe things have changed between the revs.

Edit to add: I see yours is a H PMC, probably too new for that driver, you'll have to see if newer kernel might recognize it.

That's probably the case. Thanks.
