@loongson-zn thank you for this PR. At first sight, the test/benchmark results look good and the code is clean. My first question is regarding testing, since we don't have access to this hardware. We test other architectures for which we don't have regular hosted CI available through QEMU (see https://github.com/numpy/numpy/blob/main/.github/workflows/linux_qemu.yml). Is there QEMU support for loongarch, and if so can you add a CI job in that linux_qemu.yml file?

LoongArch is promoting the Debian community, and ubuntu does not yet have a suitable toolchain, so ci is not applicable( ex: apt install gcc-xx). I am verifying with QEMU, but I have encountered some trouble. Please give me some time to debug.

@rgommers I have x86_64 crosscompile toolchain and enabling native execution via binfmt, but I encountered issues related to Python. Perhaps you can provide me with some help

I can give you a hand, what kind of issues are you facing? maybe it would be better to open a separate pull request that adds a CI test for LoongArch.

Thanks @seiko2plus, I will try my best to provide a CI testing environment within a week and start a new issue.
