freebsd kernel with SKQ
72b881cbaf
Reviewed by: jmg and jb Forced commit to provide a more meaningful commit message. John Michael-Gurney is responsible for fixing all the vast majority of the issues that arose with PCI support. Kris Kennaway and John Birrell pushed heavily on stability issues. Kris is to thank for it having even reached its current level of stability. When it reaches a production state, we will have John to thank for driving it forward. The following items are needed before sun4v can be used from CVS: - binutils/gas/config/tc-sparc.c needs to be pulled in from a modern version of binutils. - an updated version of the loader needs to be pulled in from perforce The following items need to be addressed before sun4v can be considered for deployment: - The T1 has a fairly minimal floating point unit, fsqrt and a number of other opcodes are not implemented. Emulation for unimplemented opcodes needs to be added. - Running against local disk a race condition exists whereby a cpu will sometimes run off into the weeds at tl > 2. - The MD code for interrupt handling will crash on the first ATA interrupt. - The BCM chipset (bge) is not set up correctly on the T1000. The current workaround is to use an add in Intel GigE card (em). - With KSE in the kernel signals are often not directed to the right process / thread within a process. This causes threaded processes to frequently become unkillable and gdb to not be reliable when debugging a threaded process. This issue is slowly being resolved on -threads. Many thanks go to Sun for having lent / donated a T2000 to both me and John Birrell. |

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 ``world'' target should only be used in cases where the source tree has not changed from the currently running version. See: http://www.freebsd.org/doc/en_US.ISO8859-1/books/handbook/makeworld.html for more information, including setting make(1) variables. 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.
