Is Huawei planning to ship Linux on its upcoming MateBook laptops instead of HarmonyOS NEXT? A fresh leak out of China this week suggests so. Huawei is no
This paper presents the design and implementation of HongMeng kernel (HM), a commercialized general-purpose microkernel that preserves most of the virtues of microkernels while addressing the above challenges.
Another interesting tidbit from the paper:
We started the HongMeng kernel (HM) project over 7 years
ago to re-examine and retrofit the microkernel into a general
OS kernel for emerging scenarios. To be practical for production deployment, HM achieves full Linux API/ABI compatibility and is capable of reusing the Linux applications and
driver ecosystems such that it can run complex frameworks
like AOSP [42] and OpenHarmony [35] with rich peripherals.
Yeah I only find this which is bit technical. Anything else seems marketing bs. Seems like they’re making something similar to fuchsia by google but with linux abi compatibility.
Having linux shim alone makes it effectively monolithic like xnu.They even claim this by saying linux shim will hold global state in this otherwise microkernel.
Unfortunately it seems to be a completely proprietary kernel. I did find a paper on it (presented by Huawei in a conference): https://www.usenix.org/conference/osdi24/presentation/chen-haibo
The first line of the abstract reads
