zynq_slcr_cpu_state_read(9)

🌸 NAME 🌸

Okay so bestie, this is zynq_slcr_cpu_state_read(9) from the Kernel API Manual, and its whole name is Read cpu state. That’s it. That’s the name. Iconic. 💅

💖 SYNOPSIS 💖

bool zynq_slcr_cpu_state_read (int cpu );

✨ ARGUMENTS ✨

• cpu — the cpu number, bestie. That’s the whole argument. 🫶

🦋 DESCRIPTION 🦋

So SLCR_REBOOT_STATUS saves the upper 2 bits — that’s the 31/30 cpu states for cpu0 and cpu1. If it’s 0, the cpu is running. If it’s 1, the cpu is going to die. Not me being dramatic, that’s literally what it says. 😭💀

🎀 RETURN 🎀

It returns true if the cpu is running, and false if the cpu is going to die. No cap. ✅
