Linux on HP Spectre x360 14-eu0xxx

The latest and greatest Spectre x360 iteration offers new Core Ultra 155H with new ARC GPU which is at least twice as fast compared to the Xe graphics found in a few last generations, VPU for AI acceleration and many other cool features.

But can it run Linux?

Hardware

Laptop is assembled by Quanta Computer, platform code name is DA0X3DMBAG0. If you happen to have boardview and/or schematic for the motherboard or know where to buy one please file an issue to contact me (please note that widely available DA0X3AMBAG0 schematics are for 2020 Spectre, not for this one).

You can find some photos of the motherboard in the board subfolder.

Should you buy it?

Linux won't boot without ACPI overlay and Secure Boot thus won't be usable until HP fixes the ACPI (probably never).

Synaptics releases Linux-compatible firmware only if requested by the vendor so fingerprint reader won't work without HP say-so (none of previous generations got one working).

Camera has two sensors connected to IPU6 via MIPI. Main sensor (ov08x40) has a linux driver but it's neither int3472-aware nor libcamera-compatible, IR sensor (og0va1b) doesn't have a driver at all. Neither of sensors is supported by Intel IPU6 stack (although it looks like support for ov08x40 may be coming), the same with libcamera (but this one can at least be patched) so it's unlikely either of this sensors will work without patching for at least another year.

Otherwise it's a solid laptop, but think twice.

How to install with BIOS version F.10 or later?

HP have fixed the error in ACPI that caused panics so the installation is straightforward now. WiFi wakeup wasn't fixed however so SSDT patch or other workaround is still needed.

  1. Run the installation as usual.
  2. Install IASL (usually package is named acpi-tools or acpica-tools or acpica).
  3. Download SSDT patch and compile it with iasl -tc hp-spectre-x360-14-eu0xxx-f5a.asl. There's a separate patch version for a 16-inch model.
  4. There's a number of ways to apply the resulting AML file. The easiest one is to put it to the /boot and add acpi /boot/filename.aml line to the grub config, you can do it manually via e for the first time and then switch to using some helper scripts. There're kernel means, manuals and helper scripts of loading additional ACPI tables as well.
  5. Update your kernel to at least 6.7.

How to install with older BIOS versions?

If you're using Fedora see Issue #4.

  1. Trackpad and touchscreen won't work during the setup so find a way to plug in both USB stick and a mouse at the same time if you need a mouse for the installation.
  2. Disable Secure Boot in the BIOS.
  3. Boot with modprobe.blacklist=intel_lpss_pci (press e in the grub menu, add parameter to the end of linux line, press ctrl+x to boot).
  4. Run the installation as usual.
  5. Add the same kernel parameter when rebooting to the installed system.
  6. Install IASL (usually package is named acpi-tools or acpica-tools or acpica).
  7. Download SSDT patch and compile it with iasl -tc hp-spectre-x360-14-eu0xxx-f5a.asl.
  8. There's a number of ways to apply the resulting AML file. The easiest one is to put it to the /boot and add acpi /boot/filename.aml line to the grub config, you can do it manually via e for the first time and then switch to using some helper scripts. There're kernel means, manuals and helper scripts of loading additional ACPI tables as well.
  9. With SSDT patch applied you no longer need modprobe.blacklist workaround so previously disabled devices like trackpad and touchscreen should work at this point.
  10. Update your kernel to at least 6.7.

How to fix the sound?

  1. Kernel:
    • These fixes have been submitted and accepted so you don't have to patch if you're using kernel 6.9 or later.
    • If you want to use 6.8 or older, you have to apply these two patches (patch -p1 < filename.patch in the kernel source directory) and rebuild the kernel, consult your distribution documentation on how to do it.
  2. If you have Falling back to default firmware. messages from cs35l41-hda in dmesg, your linux-firmware is outdated. You may either wait for your distribution to update the package or download the firmware from the Cirrus repository to /lib/firmware/cirrus manually. You will need following files:
    • cs35l41-dsp1-spk-cali-103c8c15-spkid0-l0.bin
    • cs35l41-dsp1-spk-cali-103c8c15-spkid0-r0.bin
    • cs35l41-dsp1-spk-cali-103c8c15-spkid1-l0.bin
    • cs35l41-dsp1-spk-cali-103c8c15-spkid1-r0.bin
    • cs35l41-dsp1-spk-cali-103c8c15.wmfw symlink to cs35l41/v6.78.0/halo_cspl_RAM_revB2_29.80.0.wmfw
    • cs35l41-dsp1-spk-prot-103c8c15-spkid0-l0.bin
    • cs35l41-dsp1-spk-prot-103c8c15-spkid0-r0.bin
    • cs35l41-dsp1-spk-prot-103c8c15-spkid1-l0.bin
    • cs35l41-dsp1-spk-prot-103c8c15-spkid1-r0.bin
    • cs35l41-dsp1-spk-prot-103c8c15.wmfw symlink to cs35l41/v6.78.0/halo_cspl_RAM_revB2_29.80.0.wmfw
  3. If you have mic mute LED constantly on, your linux-firmware is outdated. You may manually update /lib/firmware/intel/sof-ace-tplg/sof-hda-generic-2ch.tplg from the latest sof-bin release.
  4. If micmute button doesn't work on the first boot of the kernel, it can sometimes be fixed by just rebooting once more (e.g. Manjaro). If it doesn't help (e.g. Ubuntu), try to run echo -e "evdev:input:b0011v0001p0001eAB83*\n KEYBOARD_KEY_82=f20" | sudo tee /etc/udev/hwdb.d/90-internal-keyboard.hwdb > /dev/null && sudo systemd-hwdb update and reboot.

How to fix the camera?

This section is Proof-of-Concept for the time being, it might work for some use cases but it's doesn't result in a 100% functional camera. It's mostly here to show the camera will work at some point in future.

  1. Download patches 
    for i in {1..19}; do; wget -O "ipu6-$i.patch" "https://lore.kernel.org/linux-media/20240416201105.781496-$((i+1))-sakari.ailus@linux.intel.com/raw"; done
wget -O int3472.patch https://lore.kernel.org/linux-media/20231007021225.9240-1-hao.yao@intel.com/raw
wget https://raw.githubusercontent.com/aigilea/hp_spectre_x360_14_eu0xxx/main/ipu-bridge-69.patch
wget https://raw.githubusercontent.com/aigilea/hp_spectre_x360_14_eu0xxx/main/ov08x40-69.patch
  2. Apply patches in the order of download to the kernel 6.9 source tree, skip ipu6-17.patch.
  3. Ensure you have CONFIG_VIDEO_OV08X40=m, CONFIG_INTEL_SKL_INT3472=m and CONFIG_VIDEO_INTEL_IPU6=m in your kernel config file.
  4. Build & install the kernel.
  5. Ensure /lib/firmware/intel/ipu/ipu6epmtl_fw.bin file exists, update your linux-firmware package if not.
  6. Reboot and check your dmesg if ipu6 has successfully initialized and found the ov08x40 sensor.
  7. Build and install libcamera
    • git clone https://gitlab.freedesktop.org/camera/libcamera-softisp.git
    • cd libcamera-softisp
    • git checkout SoftwareISP-v10
    • wget https://raw.githubusercontent.com/aigilea/hp_spectre_x360_14_eu0xxx/main/libcamera.patch
    • patch -p1 < ./libcamera.patch
    • meson setup -Dpipelines=simple -Dipas=simple --prefix=/usr build
    • ninja -C build install
  8. Now you should be able to view the camera by launching sudo qcam -s "width=1928,height=1208". You may safely ignore missing ov08x40.yaml file error.
  9. To allow other apps to use camera you have to make pipewire to use the new libcamera, this step depends on your distribution. You can test using webrtc test page in Firefox.

Don't disable keyboard and trackpad when tilted

See Issue #5.

Enable trackpad palm rejection

The spectre has a very nice touchpad, but Linux doesn't set the correct quirks to enable the hardware palm rejection. You can install the palm-rejection systemd service to automatically set the quirks until the hid-multitouch kernel module is updated.

sudo cp palm-rejection.service /etc/systemd/system
sudo systemctl enable palm-rejection.service
sudo systemctl start palm-rejection.service
