To whomever might be attemting to run Gentoo on the same or similar hardware. There is a Gentoo wiki page about the laptop, although it is incomplete. Perhaps someone at Gentoo might like to complete it, using the information below.

Hardware info:

The machine came with Windows pre-installed. Since I wanted to keep a small Windows partition, I used a Windows tool to shrink its partition and make (lots of) room for Gentoo.

The machine boots in EFI only as far as I can tell. In order to boot an attached USB device, I had to first disable "secure boot" in the firmware. To access the firmware, you shouldn't turn the laptop on using the normal on/off button, but instead use a sharp pointy object to depress a button hidden deep behind a small hole on the righthand edge, as shown here. From there, enter the boot settings, and disable secure boot. Reboot using the same tiny hole, and now select an external USB device containing the install image.

For whatever reason, neither the Gentoo minimal install ISO, nor the Gentoo Live ISO are able to boot in EFI on this machine. Both hang during kernel boot. However, SystemRescueCD worked just fine. So I used that to boot, then followed the standard Gentoo install handbook. The internal HD is an nvme device, prepartitioned using GPT. I added the Linux partitions, and followed the rest of the Handbook without any issues.

I built a custom kernel, and made absolutely certain it had nvme and iwlwifi support, as those are needed to be able to continue installation once booting into Gentoo. I use grub2 as boot manager, and set it as the default using efibootmgr:

Code:
james@daedalus:~$ efibootmgr
BootCurrent: 0001
Timeout: 2 seconds
BootOrder: 0001,0000,0013,0014,0015,0016,0017,0018
Boot0000* Windows Boot Manager
Boot0001* gentoo
Boot0010  Setup
Boot0011  Boot Menu
Boot0012  Diagnostic Splash
Boot0013* USB FDD:
Boot0014* NVMe: HFS512GD9TNG-62A0A                     
Boot0015* USB HDD: NORELSYS 1081
Boot0016* USB CD:
Boot0017* USB LAN:
Boot0018* USB HDD: WD Elements 25A2
james@daedalus:~$ sudo efibootmgr -o 0001


After that, no more need to fiddle around with the pointy object: the normal on/off switch boots straight into grub. I have sys-boot/os-prober installed, which adds an entry for Windows to the grub menu.

I have pretty much all the hardware working: nvme internal disk, sound, microphone, graphics (I use gnome3), wifi, webcam, keyboard, touchpad, external USB devices (mouse, disks, an astronomy camera). Haven't tried bluetooth since I never use it. I am using kernel gentoo-sources-5.2.11, and I have linux-firmware installed (honestly I don't know if it's needed. Maybe the Wifi might need it)

To get the touchpad working at all, you need, as the wiki describes, designware I2C and LPSS enabled in the kernel. In addition, to have it recognized as an actual touchpad (with two-finger scrolling etc), you need hid-multitouch enabled in the kernel.
Sound requires hda-intel and the realtek codec. The webcam needs uvcvideo (and v4l obviously). Graphics are intel i915/i965

Here are some relevant kernel messages:

My VIDEO_CARDS and INPUT_DEVICES are:
Code:
james@daedalus:~$ grep VIDEO_CARDS /etc/portage/make.conf
VIDEO_CARDS="intel i965"
james@daedalus:~$ grep INPUT_DEVICES /etc/portage/make.conf
INPUT_DEVICES="libinput"


That's all I can think of. I genuinely like the machine. It's very lightweight, with good performance. Only 8GB of RAM, which is plenty for average use. Might be on the low side for serious development work. Hopefully, the information here is helpful to anyone thinking of running Gentoo on it too!
