APPLY

The patch modifies the i386 architecture. All hardware accesses and assembler instructions are replaced with with a386 calls.

To apply the patch, follow these steps:

  1. untar a frech copy of Linux 2.3.40
  2. cd path-to-Linux-2.3.40
  3. zcat path-to/patch-a386-2.3.40.gz | patch -p1
  4. mv arch/i386 arch/a386
  5. mv include/asm-i386 include/asm-a386

COMPILE

You'll need to install a386 in order to compile Linux/a386.

To compile Linux/a386, do this:

  1. edit the value of the A386_LIB variable in arch/a386/Makefile to reflect your a386 installation
  2. ln -s path-to-a386-sources/unix/include/a386 path-to-linux/include
  3. copy this file, put it in the Linux directory, and rename it .config
  4. make ARCH=a386 oldconfig
  5. make ARCH=a386 dep
  6. make ARCH=a386

RUN

You can run Linux/a386 in an unmodified Linux/i386 2.3.22 or newer. Older kernels will work only with a special patch. Other hosting operating stystems are not yet supported by a386.

To run Linux/a386:

  1. get the binary snapshot and replace vmlinux with your newly compiled vmlinux
  2. ./load vmlinux root=2a00 init=/bin/sh 2>debug.log
