−
This is the size of PersonalMmHeap. Maximum size as of 5.0.0 is 0x1FE00000.
+
When this is non-zero, the kernel reserves this amount of memory and dynamically uses it as needed for page table pages, KMemoryBlocks, and KBlockInfos. When this is zero, the process uses global shared heaps for these.
 +
 
 +
This enables a process to sacrifice some of the memory available to it in order to have higher limits on these resources, thus enabling the use of SvcMapPhysicalMemory.
 +

Maximum size as is 0x1FE00000.

Must be aligned to 0x1000. If zero, kernel will start the process's initial thread with sp=0.

In non-nspwn scenarios, values of 0 can also rarely break in Horizon. This might be something auto-adapting or a security feature of some sort?

MemoryRegionMap is supported by the kernel but not by [[Loader_services|Loader]]. Thus, only initial processes may possess this capability.
