HDMI audio

As with other CHT-based platforms, this requires Pierre-Louis Bossart's patchset (see [[../../Kernel_development#HDMI_audio|../../Kernel_development#HDMI_audio]]).

WiFi

Required 4.9 kernel patches

For the WiFi chip to be detected in the BIOS default SDIO controller enumeration mode (ACPI mode), this patch is required:

  • c2a6bbaf0c5f ("ACPI / scan: Prefer devices without _HID for _ADR matching")

This followup fix is also advised:

  • fdad4e7a876a ("ACPI / scan: Prefer devices without _HID for _ADR matching")
