vgsp: m86 - gsp-phys-gr-override SASS injection into the forwarded launch's program page
debugfs gsp-phys-gr-override (write-only, <= 1 page) stores bytes that the
forwarded launch places at the QMD's program offset inside the shadowed
program page, before any relocation. Intended use: a hand-assembled minimal
SM75 kernel (MOV R1, c[0x0][0x28]; EXIT) to prove native GR execution and the
release path independent of the guest kernel's SASS; the guest kernel's own
entry words observed in the shadow (00017a02 00000a00) are the same standard
prologue MOV encoding, so this isolates execution-path faults from code
content.
