Mount Points

This table is stored in data segment of SceIofilemgr as array of vfs_mount_point_info elements.

When sceVfsMount is executed it finds vfs_add_data element by filesystem string and then selects appropriate mount scenario by devMinor and devMajor.

Block Device Naming Rules

First level prefix: hardware device

  • int: internal eMMC
  • ext: device in game card slot
  • gcd: game card
  • mcd: device in memory card slot
  • uma: USB mass for PSTV (or pins on FAT PSVita)
  • usd: ?
  • xmc: external memory card

Second level prefix: partition table related?

  • lp - general.
  • pp - not general. cannot use on sceIoMount etc(need more test).

Third level prefix: active/inactive partition selection

  • ina: inactive
  • act: active
  • ign: ignore (for devices that don't support this)

Fourth level prefix: partition

  • a
  • unused
  • idstor
  • sloader
  • os
  • vsh
  • vshdata
  • vtrm
  • user
  • userext
  • gamero
  • gamerw
  • updater
  • sysdata
  • mediaid
  • pidata
  • entire

Partition Block Devices

Each partition has numeric alias (string) that looks like to be used to reference the partition.

Numeric names most likely follow order of partitions in MBR.

To access device node use /dev prefix (like /dev/gcd-lp-ign-gamero).

In total there can be 16 aliases from 0 to 15 per physical device (eMMC, Game Card, Memory Card). Alias 16 is hardcoded and is called entire.

Aliases 0-15 correspond to eMMC.

Aliases 100-115 correspond to Game Card.

Aliases 200-215 correspond to Memory Card.

Used by SceAppMgr.

Sets a callback function that does path mapping:

  • function tries to OverlayResolveSync input path
  • checks that it is not a PD path (Pseudo Drive mount point aquired by ScePfsMgr)
  • takes beginning of path until symbol ":"
  • tries to do a lookup by that path copy in data segment global 0x3470C mount_point_data_entry item array
  • if item is found then path from mount_point_data_entry item is copied to result_path
  • in any other case OverlayResolveSync result path is copied to result_path
