scePsmlMfsrInit, the shared-resource calls and the 800M3_2 context calls
threw or answered "not initialized", so a title that sets PSSR up at
start-up stopped there even when it never uses PSSR on hardware without
it (PPSA08330 calls the setup unconditionally and only dispatches when
sceKernelIsTrinityMode is set, which AnyPS5 reports as 0).
The layouts come from the calls in PPSA08330 and PPSA03016: requirements
are {block bytes, alignment, block count}, handles are 8-byte values
written through the first argument, and a context parameter carries its
block list at 8/16 and the shared-resources handle at 0x38. Init sets
the initialized state, the requirements ask for four 2 MiB blocks (what
PPSA08330 allocates regardless of the returned count), and create and
release keep bookkeeping objects. Invalid arguments throw because their
error codes are unknown.
The 1100 calls, scePsmlMfsrCreateContext1300 and the 900/1000/1300
dispatch packets keep returning 0x8A810001 before Init and throw after
it; packet size, mip bias and capture still throw.
The guest test links libc and gets Windows unwinding so it can check the
refused calls.

Functional
- scePsmlMfsrInit (libScePsml) - succeeds and only sets the initialized state; the shared resources and contexts are bookkeeping objects that use none of the guest blocks. Whether Sony's library fails on hardware without PSSR is unknown. PPSA08330 calls the setup unconditionally and only uses a context when its cached
sceKernelIsTrinityModeresult is set (0x3c643d, 0x567f97; otherwise it stores a -0.25 mip bias itself at 0x567fe2), which AnyPS5 reports as 0, so the dispatch, mip bias and capture calls still throw
