Functions

func Filters

func Filters() seccomp.SyscallRules

Filters returns seccomp-bpf filters for this package.

func IOCTLInvoke

func IOCTLInvoke[Cmd, Arg constraints.Integer](hostFd int32, cmd Cmd, arg Arg) (uintptr, error)

IOCTLInvoke makes ioctl syscalls with the arg of the integer type.

func IOCTLInvokePtrArg

func IOCTLInvokePtrArg[Cmd constraints.Integer, Params any](hostFd int32, cmd Cmd, params *Params) (uintptr, error)

IOCTLInvokePtrArg makes ioctl syscalls with the command of the integer type and the pointer to any given params.

func RegisterTPUDevice

func RegisterTPUDevice(vfsObj *vfs.VirtualFilesystem, minor uint32) error

RegisterTPUDevice registers devices implemented by this package in vfsObj.

func RegisterVfioDevice

func RegisterVfioDevice(vfsObj *vfs.VirtualFilesystem) error

RegisterVfioDevice registers VFIO devices that are implemented by this pacakge in vfsObj.
