Reset Management Register Functioanlity in ARM v8

techguyz

Hi Experts,

Does the Reset Management Register will be implemented mandatory or optional for the SoC based on ARMv8 and how it is practically used ?

Regards,

    In addition to what Pete said, keep in mind that setting the RMR_ELx.RR bit is only a request for a warm reset, it doesn't actually necessarily do anything by itself. For example, on ARM's Cortex-A57, setting this bit simply asserts the WARMRSTREQ signal. It's then up to the SoC to do something with this, so for example the signal being asserted could cause a power controller to warm reset the core.
