Linux/arm64

This table is a reference of linux syscalls for the arm64 architecture and their compatibility status in gVisor. gVisor does not support all syscalls and some syscalls may have a partial implementation.

This page is automatically generated from the source code.

Of 293 syscalls, 237 syscalls have a full or partial implementation. There are currently 56 unsupported syscalls.
