Intel MID

From postmarketOS
Note This page is documenting some initial research regarding the Intel MID platform

The Intel Mobile Internet Devices are a discontinued series of SoCs made by Intel. The SoFIA platform was made together with Rockchip.

Mainline support

There seems to be support for Moorefield, Moorestown, Medfield, Merrifield, in /arch/x86/platform/intel-mid. Menlow seems to be based on classic ACPI. SoFIA is unsupported on mainline, but Asus has published a downstream kernel with SoFIA support.

Firmware

Most (if not all) seem to be using the Simple Firmware Interface, which contains some elements of ACPI but is not ACPI compatible. At least Merrifield and Moorefield use SFI according to this config option (because these CPU cores are only used in Merrifield and Moorefield). SFI has been marked obsolete in the Linux kernel due to missing maintainers, but is not yet dropped. SFI was written for Moorestown, but the Linux kernel later renamed Moorestown to Intel MID which includes different SoC series, see https://lkml.org/lkml/2013/10/10/81.

SFI is similar to ACPI and it can be replaced by device tree but a lot of x86 bootloader dont support device tree.Therefore, the second stage bootloader Petitboot is neeeded to boot newer kernels with devicetree.(See Motorola RAZR i (XT890) (motorola-smi)'s device package)

Graphics

Merrifield and Moorefield make use of a PowerVR GPU, SoFIA uses a Mali GPU. The Lima driver has not yet been tested on x86, as Mali is normally used on ARM platforms.

Platforms that use PowerVR could benefit from the openpvrsgx project which is upstreaming the kernel modules so the proprietary userspace software can be used on the mainline kernel.

Devices

Note This list tries to be exhaustive, but probably isn't

Bonnell microarchitecture

Menlow platform (Silverthorne processor)

Note Menlow devices *should* be supported because it uses regular ACPI. There might be missing drivers for peripherals.
