🌸 microblaze_unwind_inner(9) 🌸

okay so bestie, welcome to the Kernel API Manual — this one's a kernel-level page for microblaze_unwind_inner(9), and it's literally the girlie that walks the stack for you. no cap, let's get into it 🫶

✨ NAME ✨

microblaze_unwind_inner — unwind the stack from the specified point 💅

🎀 SYNOPSIS 🎀

void microblaze_unwind_inner (struct task_struct *task , unsigned long
pc , unsigned long fp , unsigned long leaf_return , struct stack_trace
*trace , const char *loglvl );

🦋 ARGUMENTS 🦋

• task — the task whose stack we're gonna unwind (it may be NULL, she's flexible like that 🙈)
• pc — the program counter where we start unwinding ✨
• fp — the frame (stack) pointer where we start unwinding, the starting point of the whole vibe check 📍
• leaf_return — the value of r15 at pc. if the function is a leaf, this is the caller's return address 👑
• trace — where to store the stack backtrace (the PC values). if it's NULL, that's the signal to print the backtrace to the kernel log instead 🖨️
• loglvl — used for the printk log level if (trace == NULL). lowkey the volume knob for your logging 💬

⚠️ heads up bestie: task and trace both take NULL, but they mean different things — task = just no specific task, trace = print it to the kernel log instead of storing it. don't mix them up, iykyk 💀

that's the whole page, periodt. 💖 this absolute icon comes to you from ./arch/microblaze/kernel, dated October 2026, and yes she's serving kernel API realness in microblaze_unwind_inner(9) form — go unwind some stacks babe, you got this ⭐🧚‍♀️
