Hi, I have a Lenovo ideapad 300-14ISK, 12GB RAM, I'm a newbie in Gentoo, Linux, hardware, software, live... 8O 8O and I'm feeling really comfortable with the freedom it gives me but I have a question:

Code:

lspci -k

... some hardware that the kernel can manage

00:00.0 Host bridge: Intel Corporation Sky Lake Host Bridge/DRAM Registers (rev 08)
   Subsystem: Lenovo Skylake Host Bridge/DRAM Registers
00:14.2 Signal processing controller: Intel Corporation Sunrise Point-LP Thermal subsystem (rev 21)
   Subsystem: Lenovo Sunrise Point-LP Thermal subsystem
00:1f.0 ISA bridge: Intel Corporation Sunrise Point-LP LPC Controller (rev 21)
   Subsystem: Lenovo Sunrise Point-LP LPC Controller
00:1f.2 Memory controller: Intel Corporation Sunrise Point-LP PMC (rev 21)
   Subsystem: Lenovo Sunrise Point-LP PMC


I searched a lot of time the right software for those devices, but couldn't find anything special, I read that those are missing drivers, is it true? how can I solve this problem? (if it's a problem). Any suggestion about the kernel building?

Boot a livecd like Sabayon and run:
lspci -k > ~kernel_drivers
This will put the file in /root

Save the file and when you go back to your Gentoo install you read from that output and activate all the various drivers you need.

Skylake is too new to be used there. Worked like a charm on my previous laptop though

Thanks, it's was really useful, i've run the sabayon boot cd and i found 2 more drivers, if it helps someone else, those are the drivers:
Code:

00:14.2 Signal processing controller: Intel Corporation Sunrise Point-LP Thermal subsystem (rev 21)
   Subsystem: Lenovo Sunrise Point-LP Thermal subsystem
   Kernel driver in use: intel_pch_thermal
   Kernel module: intel_pch_thermal
00:1f.2 Memory controller: Intel Corporation Sunrise Point-LP PMC (rev 21)
   Subsystem: Lenovo Sunrise Point-LP PMC
   Kernel driver in use: intel_pmc_core


The PCM driver is here and i think the Skylake host bridge driver will be a little bit tricky. please it's the last driver, any idea? :D

There's no driver for the host bridge and none necessary either. this device connects the processor core to memory and
other busses and is configured by firmware at powerup.
