Expand description
@brief Add a memory partition into a memory domain.
Add a memory partition into a memory domain. Partitions must conform to the following constraints:
- Partitions in the same memory domain may not overlap each other.
- Partitions must not be defined which expose private kernel data structures or kernel objects.
- The starting address alignment, and the partition size must conform to the constraints of the underlying memory management hardware, which varies per architecture.
- Memory domain partitions are only intended to control access to memory from user mode threads.
- If CONFIG_EXECUTE_XOR_WRITE is enabled, the partition must not allow both writes and execution.
Violating these constraints may lead to CPU exceptions or undefined behavior.
@param domain The memory domain to be added a memory partition. @param part The memory partition to be added
@retval 0 if successful @retval -EINVAL if invalid parameters supplied @retval -ENOSPC if no free partition slots available
