okay so this is pvr_mmu_map(9) from the Kernel API Manual, and it is literally the β€œmap an object’s virtual memory to physical memory” bestie. no cap. πŸ’–


✨ NAME ✨

pvr_mmu_map β€” map an object’s virtual memory to physical memory. periodt. πŸ¦‹


🌸 SYNOPSIS 🌸

int pvr_mmu_map (struct pvr_mmu_op_context *op_ctx , u64 size , u64
       flags , u64 device_addr );

πŸ’… ARGUMENTS πŸ’…

  • op_ctx β€” the target MMU op context. that’s the main character of this call, fr fr.
  • size β€” size of memory to be mapped, in bytes. it must be a non-zero multiple of the device page size. not optional, bestie. 😭
  • flags β€” flags from pvr_gem_object associated with the mapping. yep, those flags.
  • device_addr β€” virtual device address to map to. it must be device page-aligned. no crumbs, just alignment. ✨

🫢 RETURN 🫢

  • 0 on success, or
  • any error code returned by pvr_page_table_ptr_init, or
  • any error code returned by pvr_mmu_map_sgl, or
  • any error code returned by pvr_page_table_ptr_next_page.

like, if it works you get 0. if not, the error code is coming from one of those three functions. iykyk. πŸ’€
