History

Andrew Boie 4b4f773484 libc: set up memory partitions * Newlib now defines a special z_newlib_partition containing all globals relevant to newlib. Most of these are in libc.a with a heap tracking variable in newlib's hooks. * Both C libraries now expose a k_mem_partition containing the bounds of the malloc heap arena. Threads that want to use libc malloc() will need to add this to their memory domain. * z_newlib_get_heap_bounds has been removed, in favor of the memory partition for the heap arena * ztest now includes the C library partitions in its memory domain. * The mem_alloc test now runs in user mode to prove that this all works for both C libraries.

Title: Kernel Access to Dynamic Memory Allocation functions provided by
Standard Libraries

Description:

This test verifies kernel access to the dynamic memory allocation funtions
provided by standard C libraries supported in Zephyr:
NEWLIB and MINIMAL_LIB.
It is intended to catch issues in which a library is completely absent
or non-functional, and is NOT intended to be a comprehensive test suite
of all functionality provided by the libraries.

Building and Running Project:

This project outputs to the console.  It can be built and executed
on QEMU as follows:

    make run

--------------------------------------------------------------------------------

Troubleshooting:

Problems caused by out-dated project information can be addressed by
issuing one of the following commands then rebuilding the project:

    make clean          # discard results of previous builds
                        # but keep existing configuration info
or
    make pristine       # discard results of previous builds
                        # and restore pre-defined configuration info
