libseccomp 2.5.5-2 is available on loong64 since November 25, 2024.
Thanks libseccomp's maintainer.
The building details of libseccomp 2.5.5-2 can be found at
https://buildd.debian.org/status/logs.php?pkg=libseccomp&arch=loong64.
The next, need to give-back nix for loong64, due to nix depends on the
syscall (__SNR_fchmodat2) provided by libseccomp 2.5.5-2.
Best regards,
