Was just testing it here and ran into a bug: I've L2 accessing the HPET
MMIO region that my L1 passed through from L0 (where it is supposed to
be emulated in this setup). This used to work with an older posting of
Jun, but now it locks up (infinite loop over L2's MMIO access, no L2->L1
transition). Any ideas where to look for debugging this?
