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.
