Re: [ros-dev] [ros-diffs] [ros-arm-bringup] 44871: NMI Support Patch 10: [NTOS]: Write barebones NMI Trap handler which does a TSS context switch to the NMI TSS and then calls the HAL NMI handler. [NTOS]: Implement KiSaveProcessorState for doing a PRCB context save/restore. You should now be able to test the new NMI functionality by either building the circuit referenced in my e-mail and attaching it to your PCI bus, or by using "nmi 0" in the QEMU stdio console.

But you know that CLI has no effect on NMIs?
