okay bestie, welcome to the Kernel API Manual 💖 this one's a kernel function, a 9-section manpage, and it's giving "small but important." buckle up 🎀

✨ NAME ✨

xe_pxp_submit_session_invalidation — literally just submits a PXP GSC invalidation. that's the whole job. iconic of it honestly 👑

---

🦋 SYNOPSIS 🦋

int xe_pxp_submit_session_invalidation (struct
       xe_pxp_gsc_client_resources *gsc_res , u32 id );

yes she returns an int, yes she takes two args, no we're not gonna argue about the spacing in the prototype, that's just how it's written, copy it exactly fr fr 🫶

---

🌸 ARGUMENTS 🌸

• gsc_res — the pxp client resources. this is your whole client setup bestie, the context of the operation 💅
• id — the session to invalidate. like, the specific session that's getting the ✨you're done✨ treatment 🌈

---

🔥 DESCRIPTION 🔥

okay so here's the tea ☕ this function submits a message to the GSC FW (that's the firmware, she's the main character here 👑) to notify it that a session has been terminated and is therefore invalid. gone. cooked. not valid anymore 💀

that's it. that's the whole function. it's a messenger and honestly? respect.

it returns 0 if the submission is successful — slay ✅ — and an errno value otherwise 😭 so like, check your return value, bestie, always. no cap.
