How much Linux does Huawei use? Especially with they Huawei Harmony next OS?

I think none with the Next version but Harmony OS isn’t really a replacement for Linux either. Unless HUAWEI is willing to open source Harmony China will still need an open source OS that is available to all companies in China freely. A lot of Chinese companies including Loongson are heavily reliant on Linux.

If they ban Chinese semiconductor companies from upstreaming things like compiler support into GCC they’ll be forced to fork it which wouldn’t be good. Not the end of the world but would add more development overhead to Chinese companies which is never good.

I doubt this argument. There are already two open source OS donated by Huawei to OpenAtomFoundation namely OpenHarmony and OpenEuler. Also forked from LLVM, BiSheng compiler toolchain exists that is developed by Huawei. China already tries to make itself independent from foreign software stack.

So is China immune to a Linux sanction?

Currently, i dont know may or may not. 5 years later i think yes.

Slightly tangential but Russia maintainers have been banned from contributing to the Linux kernel and have been removed from the maintainers list. There is also pressure to remove HUAWEI maintainers which would be a large blow but they’re not doing so at this time.

This is the official reason for the ban:



And this is the key piece of info for me:

all of the Linux infrastructure and a lot of its maintainers are in the US and we can't ignore the requirements of US law.

They say Linux Foundation (although international by nature) is under US law. This is noteworthy and the first time I read it so clearly stated.

Because we know US law can be very fluid, it can morph into anything at any time, this means that tomorrow they can ban Huawei, or even can ban all contributors from China. Of course we can't assume any a priori limit to what US lawmakers can do...definitely China will not, and for sure they will plan for the worst.

But software is not equipment!

Maybe China will set up a kind of China Linux Foundation with a (relatively small) group of developers that take patches from the different Chinese companies and merge them in the Chinese fork of Linux, and at the same time keep this fork in sync with upstream. It is not an impossible task, actually every company already does this for their part: they fork Linux, add their stuff, and then (also months later) submit it back for merging (but the submitted patches are already in a mergeable state, i.e. the grunt work of syncing with upstream is already done).

China had to overcome far bigger roadblocks than this in the ongoing tech war with US.

The only way US has to prevent this, is to close the sources, but at that point the glorious Linux project would be practically dead, after more than 30 years of honorable career.

Huawei and Tencent are major sponsors of the Linux Foundation. As you can see by yourself.

Which means they get Chinese financing.

NAURA's patent for "an intake pipe cleaning method and semiconductor process equipment" was published​

The present application discloses a method for cleaning an air intake pipe and a semiconductor process equipment. The air intake pipe is used as a plasma generating chamber and is used to introduce plasma into a process chamber to process wafers. The cleaning method includes: after completing the process of a preset number of wafers, introducing a first cleaning gas into the air intake pipe, and loading radio frequency power to excite the first cleaning gas; controlling the air pressure in the air intake pipe to maintain a first preset time at a first preset pressure, and to maintain a second preset time at a second preset pressure, wherein the ratio of the first preset pressure to the second preset pressure is greater than or equal to 6 and less than or equal to 14, and the ratio of the first preset time to the second preset time is greater than or equal to 0.5 and less than or equal to 2. The present application can clean the impurity particles by cleaning the air intake pipe between batches to avoid the generation of flower-shaped defects. Since the crystallization is cleaned in time, there is no need to frequently shut down the air intake pipe for replacement, thereby extending the life of the air intake pipe, reducing costs, and improving productivity.

How is it possible that a single Czech guy can create a

that is completely free of GNU and systemd and most of the shady stuff in Linux, while China is still depending on Debian as an upstream source? By the way, I wonder why both Google and Meta don't use GCC to compile the Linux kernel for their servers.

Jingcun Technology Chip Testing Headquarters Base opened to accelerate layout in the storage chip field​

Jingcun Technology has unique storage controller chip design capabilities, storage packaging solution development capabilities and chip testing factory strength. The company has a significant industry position in DRAM products, and its shipment volume in the field of embedded memory ranks among the top domestic module manufacturers. In the field of eMMC flash memory controllers, it is one of the few domestic design companies with independent intellectual property rights.

Jingcun Technology's storage chip testing headquarters base, the company has officially opened a new chapter. In the future, Jingcun Technology will take advantage of the new base to improve its overall chip testing and verification capabilities. At the same time, it will work closely with the Zhuhai Miaocun R&D team to achieve the integration of R&D and packaging and testing, accelerate the iteration speed of product R&D and production, and further enhance the company's competitiveness in the storage market.

In order to enhance the competitiveness in the storage field and promote the layout of the entire memory industry chain, since the signing of the contract at the beginning of the year, the base has been initially built and put into operation in just half a year with the joint efforts of the government and enterprises. The base mainly tests DRAM, eMMC, UFS and other chip products, which are widely used in mobile phones, tablets, OTT boxes, vehicles, artificial intelligence and the Internet of Things.

The memory chip testing headquarters base has built multiple chip testing production lines based on automation, informatization and intelligence. It has successively introduced key equipment such as automatic testing and sorting machines, Ballscan visual inspection machines, automatic plate placing machines, high and low temperature testing equipment, etc. The degree of automation has reached more than 90%, which has greatly improved production efficiency and detection accuracy, ensuring stable and reliable product quality.
