FIOS sits on top of filesystem and provides the following functionality:
* Schedule I/O requests - queue I/O operations, prioritize I/O operations, delayed (scheduled for specific time) async I/O operations, parallelized I/O operations.
* Overlays - remap I/O operations to different location. Good example is patches or localization.
* Caching - caching layer for I/O operations. I/O operations are split into chunks. Chunks can be cached in RAM. Performance can increase.
* Dearchiving - transparent filter for I/O operations that dearchives data. Good usage would be for psarc files.
Most of these functionalities are implemented in usermode in the <code>fios2.suprx</code> module.
This kernel module is only used for overlays, so that the kernel, especially [[SceIofilemgr]], is aware of FIOS2 remapping.

FIOS sits on top of filesystem and provides the following functionality:

  • Schedule I/O requests - queue I/O operations, prioritize I/O operations, delayed (scheduled for specific time) async I/O operations, parallelized I/O operations.
  • Overlays - remap I/O operations to different location. Good example is patches or localization.
  • Caching - caching layer for I/O operations. I/O operations are split into chunks. Chunks can be cached in RAM. Performance can increase.
  • Dearchiving - transparent filter for I/O operations that dearchives data. Good usage would be for psarc files.

Most of these functionalities are implemented in usermode in the fios2.suprx module.

This kernel module is only used for overlays, so that the kernel, especially SceIofilemgr, is aware of FIOS2 remapping.
