I do an experiment about cpu power with a board which has 4 cores of Cortex-A55.
I try to power on/power off core1~3 parallelly.
Sometimes Both PACCEPT and PDENY are zero after changes the power state.
If I only power on/power off one core, the signals are normal, PACCEPT is asserted.
So I want to ask what can cause getting P-channel PACCEPT/PDENY fail.
Thanks for your attention!
