Hi, qemu supports loongarch64 architecture has been completed: .
For musl loongarch64 source code can also be obtained from If necessary, we can also provide a remote testing enviroment.
See the attachment for specific modifications.

Introduction to loongarch architecture:
The Loongarch architecture is a simplified instruction computer style instruction system architecture. The instruction length is fixed and the encoding format is regular. Most instructions have only two source operands and one destination operand. The load/store architecture is adopted, that is, only load/store memory access instructions can access the memory, and the operation objects of other instructions are all It is the immediate value in the register or instruction code in the processor core.
The Loongson architecture is divided into two versions, 32bit and 64bit, called LA32 and LA64 respectively. LA64 architecture application level is downward binary compatible with LA32 architecture.
