Hello,
My GSoC project, providing thread stack protection support, has to be
a user-configurable feature.
My question is, what would be the best way to implement this, my idea
was to model it based on the existing system configuration
<https://docs.rtems.org/branches/master/c-user/config/intro.html>, but
Dr. Gedare pointed out that configuration is undergoing heavy changes
and may look completely different in future releases. Kindly advise me
as to what would be the best way to proceed.
before we start with an implementation. It would be good to define what
a thread stack protection support is supposed to do. Then there should
be a concept for systems with a Memory Protection Unit (MPU) and a
concept for systems with a Memory Management Unit (MMU). MMUs may
provide normal 4KiB Pages, large Pages (for example 1MiB) or something
more flexible. We should identify BSPs which should have support for
this. For each BSP should be a concept. Then we should think about how a
user can configure this feature.
