freebsd with flexible iflib nic queues

I do not yet understand why, but apm *depended* on the fact that the old PSE code caused the first 1MB of ram to be mapped read/write because it was in the same 4MB page as the kernel text+data+bss blob. If anybody ever tried DISABLE_PSE before, apm would not work. If your cpu did not have PSE, apm would not work there either (eg: 486). This bug has been around for a Very Long Time. The Pentium-4-fix commits did not emulate this unintended side effect of the PSE post-early-boot fixup, and thus apm blew up. I've added a hack to emulate the bug until either apm is fixed or we set fire to our bridges. This is bad though because it gives kernel mode code the opportunity to accidently write to the first few megs of the general page pool which is remapped at KERNBASE. It needs to be fixed properly. |

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/doc/en_US.ISO8859-1/books/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.
