Michael Scire 28717bfd27 fusee/pm: on 5.0.0+, fix system memory pool increase. 
Previously, we were only setting resource limit,
which didn't modify actual reserved pool size for
the system pool. This adds kernel patches which reduce
the applet pool size, granting the extra memory to
the system partition. The given value has been chosen
specifically to allow normal applet usages. Further
reduction may result in crashes during normal applet usage.

Atmosphère is a work-in-progress customized firmware for the Nintendo Switch.

Components

Atmosphère consists of multiple components, each of which replaces/modifies a different component of the system:

  • Fusée: First-stage Loader, responsible for loading and validating stage 2 (custom TrustZone) plus package2 (Kernel/FIRM sysmodules), and patching them as needed. This replaces all functionality normally in Package1loader/NX Bootloader.
    • Sept: Payload used to enable support for runtime key derivation on 7.0.0.
  • Exosphère: Customized TrustZone, to run a customized Secure Monitor
  • Thermosphère: EL2 EmuNAND support, i.e. backing up and using virtualized/redirected NAND images
  • Stratosphère: Custom Sysmodule(s), both Rosalina style to extend the kernel/provide new features, and of the loader reimplementation style to hook important system actions
  • Troposphère: Application-level Horizon OS patches, used to implement desirable CFW features
