Hi, I am working on a use case for cortex-a9/realview BSP that deals with page tables and MMU. I need your help in gathering the required API and calls and any other details to implement the following case (if applicable) :
1- A thread running on a core that updates the page table. 2- On another core another thread is running and trying to update the page table. Is that use case possible, or disabling dispatches, MMU, and interrupts avoids that situation ? Is it possible to force a thread to run on a specific core ? or the current SMP scheduler handles that ? I am thinking of applying a SHARED_MEMORY attribute on page tables itself and implement the mentioned use case. Regards, Hesham
