AFAICT, it affects CPUidle also, since CPUidle replaces pm_idle, which is protected by the hlt_counter check. I think the CPUidle folks are looking for a way to replace using pm_idle though. After that happens, there are a couple options. 1) add a check for hlt_counter in the CPUidle path, or 2) just disable CPUidle at Kconfig level. >> If runtime configuration of this is needed, then adding a debugfs >> entry for the ARM-generic hlt/nohlt interface should be added. > Is there a need for it? I don't think so. But my point was that if anyone wants this feature back, this would be the way to add it.
