💅 radeon_vce_validate_handle(9) 💅

okay so bestie, this is a page from the Kernel API Manual and it's all about radeon_vce_validate_handle — like, the little function whose whole personality is checking whether a stream handle is valid 🎀

---

✨ NAME ✨

radeon_vce_validate_handle — validate stream handle 🦋

---

✨ SYNOPSIS ✨

int radeon_vce_validate_handle (struct radeon_cs_parser *p , uint32_t
handle , bool *allocated );

like, she takes three things and gives you back an int, no cap 💜

---

✨ ARGUMENTS ✨

• p — the parser context, she's the main character of this whole operation 🫶
• handle — the handle you want to validate, literally the thing under the microscope 🔍
• allocated — did we allocate a brand new handle? a whole bool for that question bestie 💀

---

✨ DESCRIPTION ✨

so what she does is: she validates the handle and returns the found session index ✨ — or -EINVAL if we don't have another free session index 😭 like, the vibe check failed, no free sessions, that's the error, periodt.

ngl, that -EINVAL case is the "sorry bestie, no room at the inn" of this function 🙈 keep it in mind fr fr.
