kgdb_skipexception(9)

✨ kgdb_skipexception ✨

okay so real talk, bestie — this is a page from the Kernel API Manual, section 9, and it's about one lil function called kgdb_skipexception. it's short, it's sweet, and it's (optional) which is honestly such a mood. let's get into it 💅

---

🎀 NAME 🎀

kgdb_skipexception — the (optional) lil bail-out that lets you exit kgdb_handle_exception early. that's it. that's the whole vibe. no cap. ✨

---

🦋 SYNOPSIS 🦋

int kgdb_skipexception (int exception , struct pt_regs *regs );

like, that's literally the whole signature. look at her go 💖

---

🌸 ARGUMENTS 🌸

• exception — the exception vector number. yes, the number of the vector. it's giving "which exception are we even talking about" energy 🔥
• regs — the current struct pt_regs. the register state, the receipts, the whole picture. keep it close 🫶

---

💜 DESCRIPTION 💜

so on some architectures — not all of them, mind you, just some — it is required to skip a breakpoint exception when it occurs after a breakpoint has been removed. yeah. the breakpoint's gone but the exception is still out here showing up to the party 😭 main character energy fr fr.

and the way you handle that? you implement it in the architecture specific portion of kgdb. that's the assignment. that's where this function lives. periodt. 👑

💀 quick vibe check before you go: this whole thing lives in ./include/linux, and the page itself is dated October 2026. yes bestie, we're being that specific. 🎀

mwah, that's the page — kgdb_skipexception(9), from the files under ./include/linux, October 2026 edition. slay, ate, no crumbs. 🦋✨
