MPU devices that enforce power-of-two alignment now specify the size of the buffer used for the newlib heap. This buffer will be properly aligned and a pointer exposed in a kernel header, such that it can be added to a user thread's memory domain configuration if necessary. MPU devices that don't have these restrictions allocate the heap as normal. In all cases, if an MPU/MMU region needs to be programmed, the z_newlib_get_heap_bounds() API will return the necessary information. Given how precious MPU regions are, no automatic programming of the MPU is done; applications will need to do this as needed in their memory domain configurations. On x86, the x86 MMU-specific code has been moved to arch/x86 using the new z_newlib_get_heap_bounds() API. Fixes: #6814 Signed-off-by: Andrew Boie <andrew.p.boie@intel.com> |
