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.
<rnd>
means random numeric string of length 13

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.

Typical i/o operation execution
This is a very brief desctiption for overall understanding of io vfs_node
operations.
Implementation of SceIofilemgr is quite solid and most of the functions are implemented in the same manner however there could be exceptions.
When io operation like sceIoLseek
is called here is what happens:
- all user space arguments are copied to kernel space, usually onto the kernel stack. all user space uids are converted to kernel space uids
- optionally control may be passed to wrapper function that also does conversion
- then control is passed to kernel level function like
sceIoLseekForDriver
- kernel level function checks 0x2198 (IoSchedulerDispatcher initialized) flag
if dispatcher is not initialized:
- kernel level function updates 0x1964 (i/o dirty) and 0x1980 (i/o counter) flags
- kernel level function spawns separate thread and passes all arguments in single structure
- separate thread then unpacks all arguments, finds
vfs_node
and calls exported function like vfs_node_func7
- exported function packs all arguments into single stucture and calls real callback since it has
vfs_node
with node operation table
- callback routine should be located in generic device driver, like SceSdstor, SceExfatfs or ScePfsMgr. It unpacks the arguments and then does something. For example SceSdstor dispatches the call further to SceSdif, SceWlanBt, SceMsif and SceUsbMass.
- kernel level function updates 0x1980 (i/o counter) flag
if dispatcher is initialized:
- kernel level function passes arguments to wrapper
- wrapper initializes
io_contex
and assigns i/o operation index
- wrapper updates 0x1964 (i/o dirty) and 0x1980 (i/o counter) flags
- wrapper runs dispatcher function (offset 0x17C00) in separate thread. this function selects proper
vfs_node
function based on i/o operation index.
- wrapper updates 0x1980 (i/o counter) flag
i/o operation index
Typically operations are dispatched from kernel functions.
However there are exceptions: sceIoLseek32, sceIoDopenAsync, sceIoDreadAsync, sceIoDcloseAsync user functions can be dispatched.
Typically operations have normal and async version - regulated by async flag in io_context
.
However there are exceptions: sceIoLseek32, sceIoIoctlForDriver, sceIoDevctlForDriver, sceIoGetstatForDriver_2, sceIoChstatForDriver_2, sceIoDreadForDriver_2 do not have async version.

SceIofilemgrForDriver vfs callbacks
Vfs callbacks are harder to reverse since it looks like not all of them are exported. Looks like some of them are not even exposed as subroutines.
Here will go an attempt to desctibe interface of actual callbacks with single ctx argument (as opposed to exported functions that pack arguments into ctx)

SceIofilemgrForDriver vfs node callbacks
It looks like vfs callbacks are exported. Callbacks can be identified using these steps:
- Find all functions that contain indirect calls
- Locate only calls that use address, taken from table, that is pointed by vfs_node (offset 0x40, then valid offset inside pointer table)
- Trace back to first exported function (usually this is single export, not far away in call stack)
- Turns out ScePfsMgr and SceExfatfs use these exports from their vfs node function callbacks, so this information can be mapped/matched.
