Updates the app_kernel benchmark so that its default configuration does not enable timeslicing. As it is still valuable to know what kind of performance overhead is incurred by enabling timeslicing, new test configurations have been added. Signed-off-by: Peter Mitsis <peter.mitsis@intel.com> |

Title: Kernel Object Performance Description: The app_kernel test is used to measure the performance of the following kernel objects: message queues, semaphores, memory slabs, mailboxes and pipes. When the userspace version is selected (CONF_FILE=prj_user.conf), this benchmark will execute with four configurations (kernel/kernel, kernel/user, user/kernel and user/user). However, any configuration involving user threads will omit both the memory slabs and mailbox tests. -------------------------------------------------------------------------------- Sample Output:
