Editing Iso module

= Explanation =

Isolated modules are used for de-/encryption, rehashing etc.

Commonly found in [[CoreOS]], [[Talk:Files_on_the_PS3#dev_flash|dev_flash]], embedded sony selfs and service packages like [[Remarry Bluray Drive]].

They are SPU .self binaries which can be called whenever needed: e.g. decrypting and hashcheck [[Flash#EID0_-_Section_0|EID0]] for [[Product Code]] inside [[IDPS]] when called upon by lv1 (HyperVisor) to set up restrictions for Retail/CEX or Debug/DEX etc.

''Note: This page lists all isolated modules, except bootldr, metldr and other loaders from [[CoreOS]], see also [[Boot Order]]''

=== sc_iso.self ===

sc_iso.self is used by the system to handle communications to/from syscon. Once debug printing is enabled after you load it, you can see some of the internal workings including error codes for when you are trying to use the module on your own.

==== Communicating w/ sc_iso.self ====

Look in the hv bible for more detailed info, but the gist is this:

1) Send the mbmsg start packet {1, 1, [sc_iso_cmd], [sc_iso_cmd_size]}. This is in response to the 0x80 mbox int.
<br />2) On 0x81 mbox int, receive the packet (same location you sent it from), do stuff, then write back new packets and then spu_in_mbox_write(problem, seqno++)
