ENUM HW_PROTECTION_ACTION(9)

🌸 NAME 🌸

enum hw_protection_action — Hardware protection action. (hiii bestie, you're in the Kernel API Manual entry for enum hw_protection_action(9), and it's giving very demure, very kernel 💅)

✨ SYNOPSIS ✨

okay so here's the whole enum, copied exactly, spaces and all:

       enum hw_protection_action {
           HWPROT_ACT_DEFAULT ,
           HWPROT_ACT_SHUTDOWN ,
           HWPROT_ACT_REBOOT

       };

🎀 Constants 🎀

these are the three constants, and they are literally the whole menu:

• HWPROT_ACT_DEFAULT — The default action should be taken. This is HWPROT_ACT_SHUTDOWN by default, but can be overridden. (so it's the "whatever the default is" choice, but not locked in forever 🫶)
• HWPROT_ACT_SHUTDOWN — The system should be shut down (powered off) for HW protection. (powered off, no messing around 💀)
• HWPROT_ACT_REBOOT — The system should be rebooted for HW protection. (yep, full reboot for protection 🔥)
