🎀 octeon_wdt_nmi_stage3(9) 🎀

okay so bestie, this is the Kernel API Manual page for octeon_wdt_nmi_stage3 — a whole little NMI-stage-three situation, and we're gonna read it together 💖✨

💅 NAME 💅

octeon_wdt_nmi_stage3 — (the original summary after the dash is blank, no cap; the function name is the main character here 👑)

🌸 SYNOPSIS 🌸

void octeon_wdt_nmi_stage3 (u64 reg[32] );

🦋 ARGUMENTS 🦋

• reg — pointer to register state before the NMI. That's the whole argument list, periodt 💅

🔥 DESCRIPTION 🔥

NMI stage 3 handler. NMIs are handled in the following manner:

1. First NMI handler — enables CVMSEG and transfers from the bootbus region into normal memory. It is careful to not destroy any registers. (Restraint! We love to see it 🫶)
2. Second stage handler — uses CVMSEG to save the registers and create a stack for C code. It then calls the third level handler with one argument, a pointer to the register values.
3. Third, and final, level handler — is the following C function that prints out some useful infomration. (Yes bestie, the spelling is literally infomration in the original — we keep the details exactly 😭💀)
