🌸 zynq_slcr_cpu_state_write(9) 🌸

okay bestie, this page is from the Kernel API Manual, and today we’re reading zynq_slcr_cpu_state_write(9) together. it’s giving tiny-function-with-big-“please don’t crash” energy. 💖

✨ NAME ✨

zynq_slcr_cpu_state_write — Write cpu state. literally the name, no plot twist. 💅

🦋 SYNOPSIS 🦋

void zynq_slcr_cpu_state_write (int cpu , bool die );

🎀 ARGUMENTS 🎀

• cpu — cpu number.
• die — cpu state - true if cpu is going to die.

💜 DESCRIPTION 💜

so the vibe check is all about SLCR_REBOOT_STATUS. it saves the upper 2 bits (31/30 cpu states for cpu0 and cpu1). 0 means cpu is running, and 1 cpu is going to die. that’s the whole lore, bestie. 🔥

no cap: those upper 2 bits are the cpu-state gossip, and cpu0 / cpu1 are the main characters. 👑
