pvr_page_table_l1_insert(9)
π NAME π
pvr_page_table_l1_insert(9) β a Kernel API Manual page, bestie, and it's literally about inserting an entry referring to a level 0 page table into a level 1 page table. That's the whole vibe. π
β¨ SYNOPSIS β¨
void pvr_page_table_l1_insert (struct pvr_mmu_op_context *op_ctx ,
struct pvr_page_table_l0 *child_table );
π ARGUMENTS π
op_ctxβ target MMU op context pointing at the entry you're inserting the L0 page table into. πchild_tableβ the L0 page table to insert. Slay. π¦
π§ DESCRIPTION π§
okay so there are exactly two "bestie, that's on you" clauses here, and they are not optional:
Caller job #1: it is the caller's responsibility to ensure op_ctx.curr_page points to a valid L1 entry. β¨
Caller job #2: it is also the caller's responsibility to execute any memory barries (yes, that's the spelling on the page π you know what it means) to ensure that the creation of child_table is ordered before the L1 entry is inserted. Do not skip this, fr fr. π₯
