pvr_free_list_create(9)

💖 pvr_free_list_create(9) 💖

okay so bestie, welcome to the Kernel API Manual — yes, this is pvr_free_list_create(9), and no, it's not about making a playlist of free stuff (tho slay if it was). It's a kernel function, and it's actually iconic.

---

✨ NAME ✨

pvr_free_list_create — create a new free list and return an object pointer. literally that's the whole vibe: you call it, it makes you a fresh free list, and it hands you back a pointer to it. 🎀

---

🦋 SYNOPSIS 🦋

struct pvr_free_list * pvr_free_list_create (struct pvr_file *pvr_file ,
       struct drm_pvr_ioctl_create_free_list_args *args );

that's the whole signature, no cap. copy it exactly if you're writing it out, bestie. 💅

---

🌸 ARGUMENTS 🌸

• pvr_file — pointer to the pvr_file structure. it's giving "context, but make it a struct." 🫶
• args — creation arguments from userspace. yes, userspace is talking to you, and these are the deets it's sending. ✨

---

👑 RETURN 👑

so what do you get back? two possibilities, and only two:

• a pointer to the new free_list — slay, it worked 🎉
• ERR_PTR(-ENOMEM) on out of memory — aka the system ran out of memory and said "not today." 😭 handle it, don't ignore it!

---

💜 SEE ALSO 💜

• the kernel file ./drivers/gpu/drm/imagination/pvr_free_list.c — that's where the actual source lives, go read it, iykyk 🔥
• pvr_get_free_list_min_pages(9)
• calculate_free_list_ready_pages_locked(9)
• pvr_destroy_free_lists_for_file(9)
• pvr_free_list_put(9)

all of these are your little crew of related functions, bestie. go check them out if you want the full lore. 🌈

---

reminder: ERR_PTR(-ENOMEM) is not a normal pointer, so please don't dereference it like it's a valid free list. that would be a bad time. 💀
