PL011 and semihosting are the obvious choices for early debug output. There's no 8250 in the virt board so that definitely isn't going to work. We don't currently implement the ICE DCC channel, though I think Edgar was considering connecting it up to a chardev backend. Really though, I think the UART and semihosting should be enough for whatever the guest wants to do in the way of early debug. Why do you need more options? thanks -- PMM _______________________________________________ kvmarm mailing list kvmarm@xxxxxxxxxxxxxxxxxxxxx https://lists.cs.columbia.edu/mailman/listinfo/kvmarm
