History

David B. Kinder ac74d8b652 license: Replace Apache boilerplate with SPDX tag Replace the existing Apache 2.0 boilerplate header with an SPDX tag throughout the zephyr code tree. This patch was generated via a script run over the master branch. Also updated doc/porting/application.rst that had a dependency on line numbers in a literal include. Manually updated subsys/logging/sys_log.c that had a malformed header in the original file. Also cleanup several cases that already had a SPDX tag and we either got a duplicate or missed updating.

Title: Memory Slab APIs

Description:

This test verifies that the kernel memory slab APIs operate as expected.

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

Building and Running Project:

This microkernel 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

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

(3) - Further allocation results in  timeout in <RegressionTask>
===================================================================
RegressionTask: k_mem_slab_alloc times out which is expected
RegressionTask: start to wait for block
===================================================================
(4) - Free a block in <HelperTask> to unblock the other task from alloc timeout
===================================================================
HelperTask: About to free a memory block
RegressionTask: k_mem_slab_alloc OK, block allocated at 0x00104a00
RegressionTask: start to wait for block

(5) <HelperTask> freeing the next block
===================================================================
HelperTask: About to free another memory block
RegressionTask: k_mem_slab_alloc OK, block allocated at 0x00104e00
HelperTask: freed all blocks allocated by this task
===================================================================
PASS - HelperTask.
RegressionTask: Used 2 block
RegressionTask: 1 block freed, used 1 block
===================================================================
PASS - RegressionTask.
