started, but also by the turnstiles to mark a thread as runnable for all locks, for instance sleepqueues do: setrunnable()->sched_wakeup()->sched_add() In r326218 code was added to allow booting from non-zero CPU numbers by setting the ts_cpu field inside the ULE scheduler's sched_add() function. This had an undesired side-effect that prior sched_pin() and sched_bind() calls got disregarded. This patch fixes the initialization of the ts_cpu field for the ULE scheduler to only happen once when the initial thread is constructed during system init. Forking will then later on ensure that a valid ts_cpu value gets copied to all children.

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. See build(7) and https://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. See build(7), config(8), and https://www.freebsd.org/doc/en_US.ISO8859-1/books/handbook/kernelconfig.html for more information.
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 kernel configuration files reside in the sys/<arch>/conf
sub-directory. GENERIC is the default configuration used in release builds.
