 |
|
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
lshw
| Code: | *-memory UNCLAIMED
description: Memory controller
product: Sunrise Point-H PMC
vendor: Intel Corporation
physical id: 1f.2
bus info: pci@0000:00:1f.2
version: 31
width: 32 bits
clock: 33MHz (30.3ns)
capabilities: bus_master
configuration: latency=0
resources: memory:df344000-df347fff
|
lspci
| Code: | 00:1f.2 Memory controller: Intel Corporation Sunrise Point-H PMC (rev 31)
Subsystem: ASUSTeK Computer Inc. Sunrise Point-H PMC
Flags: bus master, fast devsel, latency 0
Memory at df344000 (32-bit, non-prefetchable) [size=16K]
|
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 this enabled already and the system doesn't report it in use for Sunrise Point-H SMBus.
| Code: | 0 blaze src/linux # zcat /proc/config.gz|egrep INTEL_PMC_CORE
CONFIG_INTEL_PMC_CORE=y

| Code: | 0 blaze src/linux # lspci -k

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.
