pvr_mmu_op_c..._load_tables(9)

πŸ“¦ version 7.3.1, in nixpkgs unstable

πŸ’… NAME πŸ’…

okay so bestie, this page is from the Kernel API Manual, and the function is pvr_mmu_op_context_load_tables β€” literally the glow-up that loads pointers to tables in each level of the page table tree structure you need to reference the physical page that a MMU op context is pointing at. no cap, it's giving β€œset up the whole map so the page can be found” energy πŸ’–


✨ SYNOPSIS ✨

int pvr_mmu_op_context_load_tables (struct pvr_mmu_op_context *op_ctx ,
bool should_create , enum pvr_mmu_sync_level load_level_required );

πŸŽ€ ARGUMENTS πŸŽ€

  • op_ctx β€” the target MMU op context. that's the main character here πŸ‘‘
  • should_create β€” tells the function whether new page tables should be created when empty page table entries are encountered during traversal. so like, do we make new tables or just vibe with what's there? πŸ¦‹
  • load_level_required β€” the maximum page table level to load. how high are we climbing, bestie? 🌸

πŸ’œ DESCRIPTION πŸ’œ

if should_create is true, this function may modify the stored required sync level of op_ctx as new page tables are created and inserted into their respective parents. so yeah, it can update the sync-level bookkeeping as it builds out tables β€” periodt πŸ’…

since there is only one root page table, it is technically incorrect to call this function with a value of load_level_required greater than or equal to the root level number. like, technically incorrect, bestie 😭 however, this is not explicitly disallowed here. the function won't stop you, it's just not the move. iykyk.


🌈 RETURN 🌈

  • 0 on success ✨
  • any error returned by pvr_page_table_l1_get_or_create if load_level_required >= 1 except -ENXIO, or
  • any error returned by pvr_page_table_l0_get_or_create if load_level_required >= 0 except -ENXIO.
bestie pls note that -ENXIO gets excluded from both of those error paths β€” it's literally written that way, don't @ me πŸ’€
