Software Introduction

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
