has now released the PL3 LV1 Hypercall Tracer Payload
which can be used by developers to trace PS3 syscalls and hypercalls.
at PSX-Scene (linked above) reports that [Register or Login to view links]
has dumped the PS3 LV1 syscalls, and plans to update his payload soon to allow other developers to dump the calls.
To quote: For Those Of You Who Are Asking What This Is:
level-1 syscalls are used to call hypervisor functions. On a PS3 the hypervisor is known as as "lv1? (level1) since it is the lowest level that runs directly on top of the hardware. The operating system is executed on top of this and is known as "lv2? (level2).
The two common operating systems are GameOS which PS3 games run on, and OtherOS which is usually used to run linux. Since both OSes run on top of the same lv1 hypervisor, they use the same set of hypercalls which has been partially documented here.

FINALLY able to dump (over eth) all lv1 calls!! Will push it soon!
To everyone misunderstanding: no lv1 access, all I did was be able to dump the "call trace" of lv1 hypercalls. same as payload_dump_syscalls
