The openEuler kernel is the core of the openEuler OS, serving as the foundation of system performance and stability and a bridge between processors, devices, and services.

To build and enrich documentation for openEuler project.

the memory vertical expansion technology that can achieve the purpose of memory capacity expansion and memory cost reduction.

Provides the tools to drive the Device Mapper multipathing driver.

etmem, the memory vertical expansion technology, uses DRAM and high-performance storage new media to form multi-level memory storage. By grading the stored data, etmem migrates the classified cold storage data from memory to the high-performance storage medium, so as to achieve the purpose of memory capacity expansion and memory cost reduction.
