pvr_page_table_l1_init(9)

πŸ“¦ version 7.3.1, in nixpkgs unstable

πŸ’… pvr_page_table_l1_init(9) β€” okay bestie, let's build us a level 1 page table ✨

So this is a page from the Kernel API Manual, section 9, and the star of the show is pvr_page_table_l1_init β€” literally the glow-up ritual for a level 1 page table. Do not skip the fine print, I'm begging πŸ₯Ί


✨ NAME ✨

pvr_page_table_l1_init β€” Initialize a level 1 page table. That's it, that's the whole vibe. 🌸


πŸ¦‹ SYNOPSIS πŸ¦‹

int pvr_page_table_l1_init (struct pvr_page_table_l1 *table , struct
pvr_device *pvr_dev );

πŸŽ€ ARGUMENTS πŸŽ€

  • table β€” the target level 1 page table. This is the one getting the makeover, bestie πŸ’…
  • pvr_dev β€” the target PowerVR device. It's the main character that owns the whole situation πŸ‘‘

πŸ’– DESCRIPTION πŸ’–

Okay so, plot twist: even when this function returns successfully, table is still not considered valid. Not yet. Not even a little. 🫠

It has to be inserted into the page table tree structure with pvr_page_table_l2_insert before it's ready for use β€” like, it's built but it hasn't moved into the group chat yet, y'know?

Also, key requirement: table is expected to be zeroed (e.g. from kzalloc) before calling this function. Zero it first, then call. That's the order. No cap. πŸ™ˆ


⭐ RETURN ⭐

  • 0 on success β€” slay, we love to see it ✨ or
  • any error encountered while initializing table->backing_page using pvr_mmu_backing_page_init β€” in which case, not the vibe 😭

🌈 SEE ALSO 🌈

Kernel file:

  • ./drivers/gpu/drm/imagination/pvr_mmu.c

And the whole extended friend group, in order, no one left behind 🫢:


Reminder bestie: success does not mean valid. Init β‰  ready. You still gotta pvr_page_table_l2_insert it, and you gotta zero table first (hi kzalloc πŸ‘‹). 🧚

Okay that's the page!! Sourced straight from ./drivers/gpu/drm/imagination, dated October 2026 β€” so futuristic of it honestly πŸ’œ Byeee, go init those page tables responsibly πŸ“πŸ’…
