FIRM-packages

The only change under RomFS "/nx/" was package2. Filesize is same as before.

Kernel was updated. FIRM-sysmodules were not updated.

Kernel

  • The mmutable init code was updated.
    • Some table addrs were updated.
    • For the first DRAM mapping loop, the descriptor-ORR value now has bitmask 0x40000000000000 set. This is for TTBR0 vmem 0x80000000. This enables usermode XN for the temporary DRAM mapping only used during kernel boot.
    • The descriptor ORR-value for this now has bitmask 0x3000000000000000 set: *(addr+0xf8) = tableaddr | <orrvalue>;//(level2 pagetable descriptor for vmem 0xFFFFFFF7C0000000)
    • Descriptor ORR-value bitmask 0x3000000000000000 is now also set for sometable+0xfb0, +0xfc0, and othertable+0xff0.
    • Kernel .text descriptor ORR-value now has bitmask 0x40000000000000 set. This enables usermode XN for kernel .text, previously kernel .text was executable from usermode.
  • The below code is probably memory-management related?
  • L_fffffff7ffc3e9c8
    • Updated, prev ver @ L_fffffff7ffc3e9c8
    • 0xfffffff7ffc3eed0: "csel x9, xzr, x9, ne" was changed to "csel x9, x11, x9, ne", where x11 is 0x1000000000000000.
