Kernel timeouts have always been a 32 bit integer despite the existence of generation macros, and existing code has been inconsistent about using them. Upcoming commits are going to make the timeout arguments opaque, so fix things up to be rigorously correct. Changes include: + Adding a K_TIMEOUT_EQ() macro for code that needs to compare timeout values for equality (e.g. with K_FOREVER or K_NO_WAIT). + Adding a k_msleep() synonym for k_sleep() which can continue to take integral arguments as k_sleep() moves away to timeout arguments. + Pervasively using the K_MSEC(), K_SECONDS(), et. al. macros to generate timeout arguments. + Removing the usage of K_NO_WAIT as the final argument to K_THREAD_DEFINE(). This is just a count of milliseconds and we need to use a zero. This patch include no logic changes and should not affect generated code at all. Signed-off-by: Andy Ross <andrew.j.ross@intel.com> |

Title: Microkernel Object Performance
Description:
AppKernel is used to measure the performance of microkernel events, mutexes,
semaphores, FIFOs, mailboxes, pipes, memory maps, and memory pools.
--------------------------------------------------------------------------------
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
