kgdb_arch_set_pc(9)

✨ NAME ✨

kgdb_arch_set_pc — Generic call back to the program counter — is serving major Kernel API Manual energy for kgdb_arch_set_pc(9). Bestie, this is the little hook that handles updating the program counter, and it's lowkey iconic because it needs an architecture-specific implementation to actually do the thing 💅

🌸 SYNOPSIS 🌸

void kgdb_arch_set_pc (struct pt_regs *regs , unsigned long pc );

🎀 ARGUMENTS 🎀

• regs — Current struct pt_regs. That's the regs snapshot you're working with, no cap.
• pc — The new value for the program counter. This is the glow-up value for the PC ✨

🦋 DESCRIPTION 🦋

Okay so real talk: this function handles updating the program counter, and it requires an architecture specific implementation. That means each architecture has to bring its own implementation — it's giving "you had one job, and it's updating the PC" 🔥
