-.Os
-.Sh NAME
-.Nm amd64_get_ioperm ,
-.Nm amd64_set_ioperm
-.Nd manage amd64 per-process I/O permission bitmap
-.Sh SYNOPSIS
-.Fd #include <sys/types.h>
-.Fd #include <machine/sysarch.h>
-.Ft int
-.Fn amd64_get_ioperm "u_long *iomap"
-.Ft int
-.Fn amd64_set_ioperm "u_long *iomap"
-.Sh DESCRIPTION
-.Fn amd64_get_ioperm
-copies the current I/O permission bitmap into the memory referenced by
-.Fa iomap .
-.Pp
-.Fn amd64_set_ioperm
-sets the I/O permission bitmap from the data pointed to by
-.Fa iomap .
-This call is restricted to the superuser.
-.Pp
-The permission bitmap contains 1024 bits in 32 longwords.
-If bit
-.Va n
-is clear in the bitmap, then access is granted to I/O port
-.Va n .
-If bit
-.Va n
-is set in the bitmap, then an attempt to access I/O port
-.Va n
-results in delivery of a
-.Dv SIGBUS
-signal unless the process's I/O permission level would grant I/O access.
-.Pp
-.Sy Note:
-Code using the
-.Fn amd64_get_ioperm
-and
-.Fn amd64_set_ioperm
-functions must be compiled using
-.Cm -lamd64 .
-.Sh RETURN VALUES
-Upon successful completion,
-.Fn amd64_get_ioperm
-and
-.Fn amd64_set_ioperm
-return 0.
-Otherwise, a value of \-1 is returned and the global variable
-.Va errno
-is set to indicate the error.
-.Sh ERRORS
-.Fn amd64_get_ioperm
-and
-.Fn amd64_set_ioperm
-will fail if:
-.Bl -tag -width [EINVAL]
-.It Bq Er EFAULT
-.Fa iomap
-points outside the process's allocated address space.
-.It Bq Er EPERM
-The caller was not the superuser.
-.El
-.Sh SEE ALSO
-.Xr amd64_iopl 2
-.Rs
-.%A Intel
-.%T AMD64 Microprocessor Programmer's Reference Manual
-.Re
-.Sh WARNING
-You can really hose your machine if you enable user-level I/O and
-write to hardware ports without care.
-.Sh BUGS
-The bitmap should really cover 65536 bits, but that's just too big for
-allocation in a kernel structure.
-If you need access to ports beyond 1024, use
-.Xr amd64_iopl 2 .
