bootinfo block in register r8. In locore.s we save the address in the global variable 'pa_bootinfo'. In machdep.c we compare this value against the hardwired address, but don't depend on its validity yet (ie: we still expect the bootinfo block to be at the hardwired address). After a small amount of time, we'll flip the switch and depend on the loader to pass us the address. From that moment on the loader is free to put it anywhere it likes, provided the machine itself likes it as well. Add some verbosity to aid in the transition. We emit a message if the loader didn't pass the address and we also emit a message if there's no bootinfo block at the hardwired address. While in locore.s, reduce the number of redundant serialization instructions. A srlz.i is a proper superset of a srlz.d and thus is a valid replacement. Also slightly reorder the movl instructions to improve bundle density. |

UPDATING |
This is the top level of the FreeBSD source directory. This file was last revised on: $FreeBSD$ For copyright information, please see the file COPYRIGHT in this directory (additional copyright information also exists for some sources in this tree - please see the specific source directories for more information). The Makefile in this directory supports a number of targets for building components (or all) of the FreeBSD source tree, the most commonly used one being ``world'', which rebuilds and installs everything in the FreeBSD system from the source tree except the kernel, the kernel-modules and the contents of /etc. The ``buildkernel'' and ``installkernel'' targets build and install the kernel and the modules (see below). Please see the top of the Makefile in this directory for more information on the standard build targets and compile-time flags. Building a kernel is a somewhat more involved process, documentation for which can be found at: http://www.FreeBSD.org/handbook/kernelconfig.html And in the config(8) man page. Note: If you want to build and install the kernel with the ``buildkernel'' and ``installkernel'' targets, you might need to build world before. More information is available in the handbook. The sample kernel configuration files reside in the sys/<arch>/conf sub-directory (assuming that you've installed the kernel sources), the file named GENERIC being the one used to build your initial installation kernel. The file NOTES contains entries and documentation for all possible devices, not just those commonly used. It is the successor of the ancient LINT file, but in contrast to LINT, it is not buildable as a kernel but a pure reference and documentation file.
