libLoL (LoongArch on LoongArch) is a compatibility runtime for applications designed for LoongArch's old-world ABI. By and large, these are applications built for Loongson's Loongnix reference Linux distribution and UnionTech's UOS, consisting mostly commercial applications designed for the mainland Chinese market, such as:
- Tencent's QQ for Linux
- Kingsoft's WPS for Linux
- Loongson Browser (based on Chromium)
As these applications have not yet been ported to the new-world ABI, this runtime is meant to provide help users of new-world Linux distributions use the aforementioned applications.
For a brief introduction on old-world and new-world incompatibility, please refer to this essay (in Chinese) from the Loongson Open Source Community's Are We Loong Yet? site.
libLoL consists of two components, one in the kernel-space and the other in the user-space.
- Kernel: The la_ow_syscall modules provides support for old-world system call support in the Linux Kernel, making it possible to run old-world applications on new-world (upstream) kernels.
- User-space: A patched Glibc provides symbol support for old-world applications - see the Autobuild building procedure in this repository. Additional runtime may be provided by the distribution or in binary form from Loongnix.
