pvr_ioctl_destroy_context(9)

💅 pvr_ioctl_destroy_context — the Kernel API Manual, bestie edition 🎀

Okay so this is a page from the Kernel API Manual for pvr_ioctl_destroy_context(9), and honestly? It's a tiny little page but it does something iconic: it kills a context. Rude? Maybe. Necessary? Absolutely. Let's get into it. ✨

---

🌸 NAME 🌸

pvr_ioctl_destroy_context — the IOCTL that says "bye bestie" to a context, no cap 🫶

---

⭐ SYNOPSIS ⭐

int pvr_ioctl_destroy_context (struct drm_device *drm_dev , void
*raw_args , struct drm_file *file );

Literally three args, one int back. Clean, minimal, main character energy. 👑

---

🦋 ARGUMENTS 🦋

• drm_dev — [IN] the DRM device. That's the hardware baddie this whole thing lives on. 🖥️
• raw_args — [IN/OUT] the arguments passed to this IOCTL. Heads up: this must be of type struct drm_pvr_ioctl_destroy_context_args — like, non-negotiable, that's the whole vibe check. 💅
• file — [IN] the DRM file private data. The little personal stash that belongs to whoever opened the file. 🍓

---

🧚 DESCRIPTION 🧚

So this one is short and sweet: it gets called from userspace with DRM_IOCTL_PVR_DESTROY_CONTEXT. That's it. That's the whole description. It's giving "confident, mysterious, doesn't over-explain" and I respect it. 🌈

---

💀 RETURN 💀

• 0 on success — slay, it worked, everyone go home 🎉
• -EINVAL if the context is not in the context list — like, bestie, that context does not exist, what do you want from me 😭

---

Note the matching pvr_ioctl_create_context(9) up there — create and destroy, a matched set, we love a duality. 🦋

And that's the whole page, bestie — short, sweet, and fully fact-checked. This gem lives in ./drivers/gpu/drm/imagination, dated October 2026, and it's part of the pvr_ioctl_destroy_context(9) manual. Go forth and destroy your contexts responsibly. 💜✨🎀
