TencentOS Kernel is a server operating system developed by Tencent for cloud scenarios.

Tencent OS Kernel (also known as Tencent Linux, or Tlinux for short) is a Linux operating system developed by Tencent for cloud scenarios. It provides special functional features and performance optimization, providing a high-performance, more secure and reliable operating environment for applications in cloud server instances.

Support platform

X86: Support Intel, AMD (including ROME platform).
ARM64: supports hot patches and virtualization.

Main characteristics

Property Type	Characteristic content
Kernel customization	It is customized based on the 4.14.105 version that has been supported by the kernel community for a long time, adding new features suitable for cloud scenarios, improving kernel performance, and repairing major defects
Container support	The container scenario is optimized to provide isolation enhancement and performance optimization features: meminfo vmstat、cpuinfo、stat、loadavg, uptime, diskstats Sysctl isolation, such as the BUGFIX of tcp_no_delay_ack and tcp_max_orphans file systems and networks NVME IO isolated proportionally
performance optimization	The computing, storage and network subsystems have been optimized, including optimizing the xfs memory allocation, solving the xfs kmem_alloc allocation failure alarm, optimizing the network packet receiving and large memory allocation, and solving the problem of occupying too much memory when UDP packets are large, limiting the proportion of memory occupied by the system page cache, so as to avoid the impact of insufficient memory on business performance or OOM
Other characteristics	Offline scheduling algorithm (BT) Process anti gdb ARM64 hot patch pagecache limit
Defect support	It provides the kdump kernel dump capability after the operating system crashes. It provides the hot patch upgrade capability of the kernel
Security Update	Tencent Linux will be updated regularly to enhance security and functions

This is also called floor washing? Does it mean that Tesla will not wash the floor if it releases all the source code? Some people HWptds? That is to say, the language is ambiguous, which will also rise to the washing ground? Are some people too focused? Think the people he pays attention to must be staring at?

The world only knows that Android was created by Google. Several people know that Android is only a product acquired by Google. Similarly, what is the problem with Huawei's contribution to the collection of OGG open source work and integration into its own proprietary product line?

One thing to say, compared with other domestic manufacturers, Qwen's relaxed licensing fully demonstrates the style of a large factory

But the end of closed source must be open source, because many people who are dissatisfied with closed source have created open source, so the end of open source is not necessarily closed source, but to find a business model that is open source= Free Admission

Yeah, for 2024-05-17 13:42

That's too right. Old Zhou can't control Google, but he can control 360. Do not do to others what you do not want. All 360 products should be opened first.

I suggest that 360 open source all its products, and then become the leading enterprise in the domestic open source industry through open source, leading everyone to compete with foreign enterprises

Bullshit authentication

Although France is the parent community, the core developers of OCCT on github are all Russians. Without Russians, the French parent community cannot continue to operate. So Huawei took over, moved to China, changed its name and resumed open source and community operations. What's the problem?

I dare not use it

I transferred tens of thousands of yuan to my own account, which was under risk control. How did I do this? The bank should be responsible for this**

I'm laughing to death. Those who have been deeply kidnapped dare not pay? Who will use the domestic open source framework of small companies in the future will be 213!!! Wait for harvesting later
