→IoctlVs: Clarify state of 0x90, 0x91, 0x92 after the research I did a while back
Line 855:
Line 855:
−Presumably, the ioctlv would have validated size and alignment, and then filled in additional parameters on the command before passing it on to the shared logic that it is still accessible via the ioctlv. However, no PPC-side code exists so the exact ioctlv arguments are unknown.

−<strong>Dummied out on all current IOS versions</strong>; always returns 0x80. However, still usable as an Ioctl (which is probably unintended). System menu 4.3U (among other titles) still has a PPC-side implementation (815504c4) but this is not used (the higher-level function that calls it is gone due to not being referenced).

No PPC-side code exists for this command in any known title (it was never called, even in an unreachable in practice way, so the function was optimized out).

This does allow determination of the inputs, though:
