Where did you get this from? I haven't started looking at GA100 yet, but this
is news to me.
From Open RM:
GA100 returns FRTS size = 0 via kgspGetFrtsSize__0x00000000, while all
other Turing/Ampere/Ada chips use kgspGetFrtsSize_TU102, which returns
1MB.
GA100's kgspPrepareForFwsecFrts is stubbed out. It returns
NV_ERR_NOT_SUPPORTED, vs. the real kgspPrepareForFwsecFrts_TU102 used by
GA102+.
The boot sequence in kernel_gsp_tu102.c guards FWSEC-FRTS with if
(kgspGetFrtsSize_HAL(...) > 0), so GA100 (returning 0) skips it
entirely.
