SceAppMgr

AppId
Some functions take an AppId as argument.

Data segment layout
On 3.60 :

Explanation
AppMgr operates with such term as.

Different ids correspond to different paths and are described at SceAppMgr_Mount_IDs

There are many different mount functions in AppMgr which mount different paths with corresponding.

However on the bottom level there is only one single function that is responsible for all mount operations.

It is located in segment 0 at offset 0x19B51 on 3.60.


 * pid - current process pid.


 * mount_ctx_holder - root holder of appmgr_mount_t (stored in segment 1).


 * mount_id - mount id to use for this mount operation.


 * title_id - title id of the application.


 * physical_path - path like ux0:app/


 * mount_drive - virtual drive like app0:. This may be also randomly generated. This argument goes to . This argument is optional. When empty - will be generated by.


 * klicensee - klicensee for this mount operation. This argument is optional.


 * mount_point_result - mountpoint for the user. Returned from.

AppMgr maintains two parallel lists in segment 1.

One of the lists contains  items.

These are the items that are exposed to user of AppMgr library.

is what is returned as  when user calls some mount functions in AppMgr.

in many cases is randomly generated (but not always).

Other list is an internal list of  items.

These items store arguments that are used for calling PFS mount.

Each item also has randomly generated  in form of PDXXXXXXXXXXXXd.

When  is called, it creates both   and   items and links them with.

Each item is put in a corresponding list.

This mapping relation is important and shows how AppMgr mountpoint translates to PfsMgr mountpoint.

All basic relations are shown on a diagram example with black color.

However there is another  relation between items which is especially important for sceAppMgrGameDataMountForDriver.

This relation is illustrated on diagram with red color and applies to pairs of s: 0x3E8,0x3E9 or 0x3EA, 0x3EB.

Such relation is used to setup multiple mount levels. For example app (0x3E8) with patch (0x3E9) on top. Or addcont (ro) (0x3EA) with addcont (rw) (0x3EB) on top.

Additionally multiple mount levels are controlled using fios overlays, hence  in.

Overlay is a concept of filesystem path redirection/remapping. Additional description is at SceFios2Kernel

Table below shows how overlays are created for 0x3E8, 0x3E9, 0x3EA, 0x3EB for given

Overlay is created with sceFiosKernelOverlayAddForProcessForDriver

This results in a path remapping, where when user reads from  virtual drive, he will actually read from.

However if patch directory was present, further path remapping will happen, so that user will read from.
