ControlProcessMemory maps memory in the specified process, this is the only SVC which allows mapping executable memory. Format of the permissions field for memory mapping SVCs: bit0=R, bit1=W, bit2=X. Type6 sets the Addr0 memory permissions to the input permissions, for already mapped memory. Type is the MemoryOperation enum, without the memory-type/memory-region. ControlProcessMemory only supports type4, type5, and type6. ControlProcessMemory does not support using the current KProcess handle alias.

MapProcessMemory maps memory from a given process into the current process using a virtual memory address range that is offset by 0x07f00000 from the original address range. In other words, the memory range [StartAddr,EndAddr] is mapped to [StartAddr+0x07f00000,EndAddr+0x07f00000]. This is used by [[RO Services]] to map memory from 0x00100000 to 0x08000000. Memory mapped by MapProcessMemory is unmapped by UnmapProcessMemory.

<code>'''MapProcessMemory'''(Handle process, u32 destAddr, u32 limit)</code> maps memory from the given process into the current process. First <code>min(limit, 0x3F00000)</code> bytes are mapped starting from <code>0x00100000</code> in the source process to <code>destAddr</code> in the current process. Then <code>min(limit - 0x7F00000, 0x6000000)</code> bytes (if more than 0) are mapped from <code>0x08000000</code> in the source process to <code>destAddr + 0x7F00000</code> in the current process. Another way to view this is that it is overlaying the two ranges <code>[0x0010_0000; 0x0400_0000]</code> and <code>[0x0800_0000; 0x0E00_0000]</code> from the source process onto <code>destAddr - 0x100000</code> in the current process, but only covering up to <code>limit + 0x100000</code> bytes. This is used by [[RO Services]] to map the program's code and heap into ro. Memory mapped by MapProcessMemory is unmapped by UnmapProcessMemory.

Note that with the MAP MemoryOperation, the kernel will refuse to MAP memory for the specified addr1, when addr1 was already used with another MAP operation as addr1. The kernel also doesn't allow memory to be freed via the FREE MemoryOperation, when other virtual-memory is mapped to this same memory(when the MAP MemoryOperation was used with this memory with addr1).
