Line 345:
Line 345: − If dstaddr >= LowerTreshold, the dst-range is enforced to be within the process' "MapRegion". Code can get the range of this region from [[#svcGetInfo]] id0=2,3.+ − In this case, the mapped memory will have state 0x5C3C0B.+ − As long as (dstaddr+size) < LowerThreshold, then you can map anywhere but the mapped memory will have state 0x482907 instead.+ − LowerTreshold is 0x80000000 for 36-bit address spaces, and 0x40000000 for 32-bit ones.+ − [2.0.0+] Support for the 0x482907 mappings outside the "MapRegion" were removed.+ Line 799:

Source range gets reprotected to --- (it can no longer be accessed), and bit0 is set in the source [[#MemoryAttribute]].
Source range gets reprotected to --- (it can no longer be accessed), and bit0 is set in the source [[#MemoryAttribute]].
[1.0.0] This could be used to map into either the Alias Region or the Stack region.
[2.0.0+] This can only be used to map into the Stack region.
Code can get the range of the Alias region from [[#svcGetInfo]] id0=2,3, and on 2.0.0+ the range of the Stack region via [[#svcGetInfo]] id0=14, 15 (on 1.0.0, the Stack region had hardcoded limits).
When mapped into the Alias region, the mapped memory will have state 0x482907.
When mapped into the Stack region, the mapped memory will have state 0x5C3C0B.
