Description

AIM (Appliance Info Manager) is a Process socket service supported by the hypervisor (lv1).

It is used to retrieve the IDPS, Target ID, Open PSID and PS Code from the EID0 data that is passed in.

Responsible is the isolated SPU module aim_spu_module.self from CoreOS / Flash.

This service is accessible from GameOS via syscall 867 and requires 0x40 Root flag (Capability Flags) set in Plaintext Capability Header.

int cellSsAimGetPsCode(out:uint8[8]);

0x19005 - Get Open PS ID

calling from GameOS:

struct ss_aim_get_open_ps_id {
    u8 field0[16];
};

int cellSsAimGetOpenPsId(out:uint8[0x10])

0x19006 - unkonwn

  • Usage found in bdp_BDVD for example... with 1 param (= 0)
  • Seems to be handled by lv2_kernel, not AIM itself.
  • It looks up for qa-flag (if flagged, sets token seed to an lv2 internal buffer), fself flag & device_id.

calling from GameOS:

int syscall(867, 0x19006);
  • note: this packet id doesnt need another parameter
