vgsp: golden9d - FBMEM channel memdescs and FBMEM MAIN
The golden9c cycle reached the promote commit and hung the GR engine in the
ctxsw wait (FECS_A/B TDR records then a fatal assert). The real golden capture
carried client-local FBMEM instance/USERD/RAMFC/mthd memdescs and FBMEM ctx
buffers; the host-sysmem substitution is the remaining aperture difference.
Allocate one FBMEM block for the four channel memdescs (sliced 0x1000/0x200/
0x1000/0x1000 like the client memmgr) and back the promoted MAIN with the
server FBMEM allocation (VIDMEM physAttr 0x4, VIDMEM PDB leaf PTEs) for mode
25. PATCH/FECS/PRIV/UNR stay host sysmem in this iteration.
