- Remove the sched_add wrapper that used sched_add_internal() as a backend. Its only purpose was to interpret one flag and turn it into an int. Do the right thing and interpret the flag in sched_add() instead. - Pass the flag argument to sched_add() to kseq_runq_add() so that we can get the SRQ_PREEMPT optimization too. - Add a KEF_INTERNAL flag. If KEF_INTERNAL is set we don't adjust the SLOT counts, otherwise the slot counts are adjusted as soon as we enter sched_add() or sched_rem() rather than when the thread is actually placed on the run queue. This greatly simplifies the handling of slots. - Remove the explicit prevention of migration for ithreads on non-x86 platforms. This was never shown to have any real benefit. - Remove the unused class argument to KSE_CAN_MIGRATE(). - Add ktr points for thread migration events. - Fix a long standing bug on platforms which don't initialize the cpu topology. The ksg_maxid variable was never correctly set on these platforms which caused the long term load balancer to never inspect more than the first group or processor. - Fix another bug which prevented the long term load balancer from working properly. If stathz != hz we can't expect sched_clock() to be called on the exact tick count that we're anticipating. - Rearrange sched_switch() a bit to reduce indentation levels. |

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.
