PXI Services
The 'pxi' sysmodule contains the following services:
- PxiFS0
- PxiFS1
- PxiFSB
- PxiFSR
- PxiPM
- pxi:am9
- pxi:dev
- pxi:mc
- pxi:ps9
Each of these services has up to 4 static IPC buffers of size 0x1000. When any of these service ports are sync:d, the IPC cmdbuf (TLS+0x80+) is sent over PXI to the ARM9.
Each PXI service can only have one session open for it at a time.
