with-serde

Various types can be serialized with Serde. This can be enabled with: syscalls = { version = "0.3", features = ["with-serde"] }

The Enum column means that a Sysno enum is implemented for this architecture.

The Invoke column means that syscalls can be invoked for this architecture.

| Arch | Enum | Invoke | |:-----------:|:----:|:------:| | arm | ✅ | ✅ | | aarch64 | ❌ | ❌ | | mips | ✅ | ✅ | | mips64 | ✅ | ✅ | | powerpc | ✅ | ✅ | | powerpc64 | ✅ | ✅ | | s390x | ✅ | ✅ | | sparc | ✅ | ❌ | | sparc64 | ✅ | ❌ | | x86 | ✅ | ✅ | | x86_64 | ✅ | ✅ |

Updating the syscall list

Updates are pulled from the .tbl files in the Linux source tree.

1. Change the Linux version in syscalls-gen/src/main.rs to the latest version. Using a release candidate version is OK.
2. Run cd syscalls-gen && cargo run. This will regenerate the syscall tables in src/arch/.
