dpu_core_irq_uninstall(9)

💅 dpu_core_irq_uninstall 💅

okay so bestie, welcome to the Kernel API Manual ✨ this one's a lil function from the DRM/MSM world and honestly she's short but she matters. the name is literally dpu_core_irq_uninstall and she does exactly what it says on the tin: uninstall core IRQ handler 🎀 no cap, that's the whole vibe.

---

✨ SYNOPSIS ✨

void dpu_core_irq_uninstall (struct msm_kms *kms );

so yeah, she takes exactly one (1) argument, returns nothing, and dips 🫶 she's a void girlie, she gives and she takes nothing back. main character energy fr fr.

---

🦋 ARGUMENTS 🦋

• kms — the MSM KMS handle 💫 that's your ticket, your little pass into the KMS (kernel mode setting) side of things. you hand her this handle and she knows what's up. it's giving "here's my ID, let me in" 😭

---

🌸 RETURN 🌸

none 💀 literally nothing. she returns no value. don't go looking for a return code, don't assign her to a variable, she's not that kind of function. void is void, periodt 👑
