Peter Maydell a96edb687e target/arm: Implement FEAT WFxT and enable for '-cpu max' ... FEAT_WFxT introduces new instructions WFIT and WFET, which are like the existing WFI and WFE but allow the guest to pass a timeout value in a register. The instructions will wait for an interrupt/event as usual, but will also stop waiting when the value of CNTVCT_EL0 is greater than or equal to the specified timeout value. We implement WFIT by setting up a timer to expire at the right point; when the timer expires it sets the EXITTB interrupt, which will cause the CPU to leave the halted state. If we come out of halt for some other reason, we unset the pending timer. We implement WFET as a nop, which is architecturally permitted and matches the way we currently make WFE a nop.
