.Dt OSF/1 4 alpha
|
|
.Os
|
|
.Sh NAME
|
|
.Nm osf1
|
|
.Nd OSF/1 ABI support
|
|
.Sh SYNOPSIS
|
|
To load the OSF/1 ABI support kernel module:
|
|
.Dl kldload osf1
|
|
.Sh DESCRIPTION
|
|
The
|
|
.Nm
|
|
module provides limited
|
|
alpha OSF/1 (also known as Digital UNIX, later known as Tru64 UNIX)
|
|
ABI (application binary interface)
|
|
compatibility for userland applications.
|
|
The module provides the following significant facilities:
|
|
.Bl -bullet
|
|
.It
|
|
An image activator
|
|
for ecoff executable images
|
|
.It
|
|
Special signal handling for activated images
|
|
.It
|
|
OSF/1 to native system call translation
|
|
.El
|
|
.Pp
|
|
It is important to note that the OSF/1 ABI support
|
|
it not provided through an emulator.
|
|
Rather, a true (albeit limited) ABI implementation is provided.
|
|
.Pp
|
|
The
|
|
.Nm
|
|
module can be loaded as required.
|
|
The following command will load the module
|
|
if it is not already loaded as a module:
|
|
.Bd -literal -offset indent
|
|
if ! kldstat -v | grep -E osf1_ecoff > /dev/null; then
|
|
kldload osf1 > /dev/null 2>&1
|
|
fi
|
|
.Ed
|
|
.Pp
|
|
Note that dynamically linked OSF/1 executables
|
|
will require a suitable environment in
|
|
.Pa /compat/osf1 .
|
|
.Pp
|
|
For information on loading the
|
|
.Nm
|
|
kernel loadable module automatically on system startup,
|
|
see
|
|
.Xr rc.conf 5 .
|
|
.Sh FILES
|
|
.Bl -tag -width /compat/osf1 -compact
|
|
.It Pa /compat/osf1
|
|
minimal OSF1 run-time environment
|
|
.El
|
|
.Sh BUGS
|
|
We cannot run OSF/1 applications which rely on the
|
|
.Xr pthread 3
|
|
API, such as the JDK.
|
|
OSF/1's pthreads library uses Mach system calls.
|
|
Mach system calls would be very difficult to support in
|
|
.Fx .
|
|
.Pp
|
|
Linking the
|
|
.Nm
|
|
module into the kernel statically is not supported.
|
|
.Sh HISTORY
|
|
OSF/1 ABI support first appeared in
|
|
.Fx 4.0 .
