In November 2021 Linux kernel 5.16 release, the detection of Vortex86 processors is added with properly identification.
DMP’s Vortex86 SoCs work well with various legacy Linux distributions without a dedicated but a generic x86 32-bit kernel. The Vortex86 32-bit SoCs have worked under Linux for those distributions still maintaining 32-bit x86 support and where not hitting corner-cases of some i686 level features not being supported by some Vortex86 cores. Now with the detection in Linux Kernel 5.16, not only legacy but also new application powered by Vortex86 can take the advantage of this kernel release.
Vortex86 CPUs aren't vulnerable to Spectre and Meltdown since they are an in-order design and lack CLFLUSH instruction. Also, the Linux kernel has properly catered to Vortex86 and identified them correctly applying the no performance-hitting mitigations.
