I've tried to package a build agent container for loong64 based on Debian sid and the recently-merged riscv64 port, seems it's not currently feasible:

FYI on LFS the test seems fine:

PYTHONPATH=../../../util VALGRIND="" python3 ./t_cccol.py 
LD_LIBRARY_PATH=`echo -L../../../lib | sed -e "s/-L//g" -e "s/ /:/g"` KRB5_CONFIG=../../../config-files/krb5.conf LC_ALL=C  ./t_cc

After the test finishes:

I've recently started working on porting the VSCodium Remote Extension Host (REH) Server to the LoongArch architecture. By replacing several binaries in the existing x64 build with LoongArch equivalents, I managed to get it working successfully. I was able to connect to the server using the VSCodium client on Windows without any issues.

My next step is to build the VSCodium REH Server natively within a LoongArch build container to streamline the process and ensure better compatibility. After that, I might look into porting the VSCodium client itself to LoongArch.

UPDATE: REH Server PR merged: VSCodium/vscodium#2087

My next steps:

1. Build some older versions of REH Server and add them to existing VSCodium releases
2. Purpose a PR for loong64 in https://github.com/jeanp413/open-remote-ssh
3. Work with lcpu-club for Electron on loong64, which seems to be the last obstacle from building the VSCodium client natively

Electron on loong64 is entirely possible (you can see from https://github.com/loongson/electron/) but lots of work required.
