From a6c822020d368106b01f399673116ff8716835c7 Mon Sep 17 00:00:00 2001 From: markm Date: Sun, 1 Aug 2004 11:40:54 +0000 Subject: Break out the MI part of the /dev/[k]mem and /dev/io drivers into their own directory and module, leaving the MD parts in the MD area (the MD parts _are_ part of the modules). /dev/mem and /dev/io are now loadable modules, thus taking us one step further towards a kernel created entirely out of modules. Of course, there is nothing preventing the kernel from having these statically compiled. --- sys/amd64/include/memdev.h | 38 ++++++++++++++++++++++++++++++++++++++ 1 file changed, 38 insertions(+) create mode 100644 sys/amd64/include/memdev.h (limited to 'sys/amd64/include/memdev.h') diff --git a/sys/amd64/include/memdev.h b/sys/amd64/include/memdev.h new file mode 100644 index 0000000..b6d3122 --- /dev/null +++ b/sys/amd64/include/memdev.h @@ -0,0 +1,38 @@ +/*- + * Copyright (c) 2004 Mark R V Murray + * 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.
