From f14ea10694ed07a2d0627c9efa2b79c03b19639d Mon Sep 17 00:00:00 2001 From: sos Date: Sun, 25 Jun 1995 17:32:43 +0000 Subject: First incarnation of our Linux emulator or rather compatibility code. This first shot only incorporaties so much functionality that DOOM can run (the X version), signal handling is VERY weak, so is many other things. But it meets my milestone number one (you guessed it - running DOOM). Uses /compat/linux as prefix for loading shared libs, so it won't conflict with our own libs. Kernel must be compiled with "options COMPAT_LINUX" for this to work. --- sys/modules/linux/linux.c | 58 +++++++++++++++++++++++++++++++++++++++++++++++ 1 file changed, 58 insertions(+) create mode 100644 sys/modules/linux/linux.c (limited to 'sys/modules/linux/linux.c') diff --git a/sys/modules/linux/linux.c b/sys/modules/linux/linux.c new file mode 100644 index 0000000..183ad3e --- /dev/null +++ b/sys/modules/linux/linux.c @@ -0,0 +1,58 @@ +/*- + * Copyright (c) 1994 Søren Schmidt + * All rights reserved. + * + * Redistribution and use in source and binary forms, with or without + * modification, are permitted provided that the following conditions + * are met: + * 1.
