This implements per-thread counters for PMC sampling. The thread descriptors are stored in a list attached to the process descriptor. These thread descriptors can store any per-thread information necessary for current or future features. For the moment, they just store the counters for sampling. The thread descriptors are created when the process descriptor is created. Additionally, thread descriptors are created or freed when threads are started or stopped. Because the thread exit function is called in a critical section, we can't directly free the thread descriptors. Hence, they are freed to a cache, which is also used as a source of allocations when needed for new threads.

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.
NOTES contains entries and documentation for all possible
devices, not just those commonly used.
