| Added with [[8.0.0-18]]. This can be mapped via descriptors in the [[NCCH#CXI|CXI]] exheader. The GSP module converts this virtual-mem to phys-mem by adding the input vaddr with value 0x800000. The kernel maps this to 0x1E800000+<total size specified in exheader converted to bytes>, therefore that byte-size likely must always be 0x00400000. It's unknown what this region is used for(this phys-mem region was not known to be used at all before), this area is not accessible to the GPU(on an original 3DS system at least).
| New3DS VRAM, access to this is specified by the exheader. Added with [[8.0.0-18]]. This area is used by [[QTM Services]]. This area is not accessible to the GPU on an original 3DS system.
