These patches is to add dependencies of POWER_RESET for MIPS Malta, x86, and PowerMac. To simplify the enablement of the poweroff support, selecting the required options for CONFIG_POWER_RESET=y may make many people happyespecially when they are using a customized config (maybe tinyconfigbased) for a target qemu board. Without normal poweroff support from the kernel side, qemu will simply hang[1] there after a 'poweroff' command, which is a very bad experience for the automatical tests. Currently, based on tinyconfig, it is very hard to find the exact poweroff options[2]. Some architectures' poweroff works well without any dependence, the others' poweroff options are hidden deeply, which make things hard. After multiple verifications, these options have been identified as the minimum dependencies required for poweroff to function normally. Zhangjin and I invested a significant amount of time in searching for the current options on these devices. We hope that this set of patcheswill save time for others. If community like it, we will consider adding dependencies for POWER_RESET on other devices. --- [1]: https://lore.kernel.org/lkml/511b2f6009fb830b3f32b4be3dca99596c684fa3.1689759351.git.falcon@xxxxxxxxxxx/ [2]: https://lore.kernel.org/all/983843582e52e83fba79ad45cea6c79e1f62ec6c.1690489039.git.falcon@xxxxxxxxxxx/ Yuan Tan (3): kconfig: add dependencies of POWER_RESET for mips malta kconfig: add dependencies of POWER_RESET for x86 kconfig: add dependencies of POWER_RESET for PowerMac arch/mips/Kconfig | 3 +++ arch/powerpc/platforms/powermac/Kconfig | 1 + arch/x86/Kconfig | 2 ++ 3 files changed, 6 insertions(+) -- 2.34.1
