Introducing CMake is an important step in a larger effort to make Zephyr easy to use for application developers working on different platforms with different development environment needs. Simplified, this change retains Kconfig as-is, and replaces all Makefiles with CMakeLists.txt. The DSL-like Make language that KBuild offers is replaced by a set of CMake extentions. These extentions have either provided simple one-to-one translations of KBuild features or introduced new concepts that replace KBuild concepts. This is a breaking change for existing test infrastructure and build scripts that are maintained out-of-tree. But for FW itself, no porting should be necessary. For users that just want to continue their work with minimal disruption the following should suffice: Install CMake 3.8.2+ Port any out-of-tree Makefiles to CMake. Learn the absolute minimum about the new command line interface: $ cd samples/hello_world $ mkdir build && cd build $ cmake -DBOARD=nrf52_pca10040 .. $ cd build $ make PR: zephyrproject-rtos#4692 docs: http://docs.zephyrproject.org/getting_started/getting_started.html Signed-off-by: Sebastian Boe <sebastian.boe@nordicsemi.no> |

Title: Memory Slab APIs
Description:
This test verifies that the kernel memory slab APIs operate as expected.
--------------------------------------------------------------------------------
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
--------------------------------------------------------------------------------
Sample Output:
starting test - Test Kernel memory slabs
Starts main
===================================================================
(1) - Allocate and free 2 blocks in <main>
===================================================================

MAP_LgBlks used 2 blocks
k_mem_slab_alloc RC_FAIL expected as all (2) blocks are used.

===================================================================
===================================================================
(3) - Further allocation results in timeout in <main>
===================================================================
main: k_mem_slab_alloc times out which is expected
main: start to wait for block
===================================================================
(4) - Free a block in <helper_thread> to unblock the other task from alloc timeout
===================================================================
helper_thread: About to free a memory block
main: k_mem_slab_alloc OK, block allocated at 0x00406000
main: start to wait for block
===================================================================
(5) <helper_thread> freeing the next block
===================================================================
helper_thread: About to free another memory block
main: k_mem_slab_alloc OK, block allocated at 0x00406400
helper_thread: freed all blocks allocated by this task
PASS - helper_thread.
===================================================================
main: Used 2 block
main: 1 block freed, used 1 block
PASS - main.
