pvr_page_ta...ntry_raw_set(9)
π NAME π
okay so bestie, welcome to pvr_page_table_l1_entry_raw_set(9) from the Kernel API Manual, section 9 β and it is literally the function that writes a valid entry into a raw level 1 page table. No cap. π
β¨ SYNOPSIS β¨
void pvr_page_table_l1_entry_raw_set (struct pvr_page_table_l1_entry_raw
*entry , dma_addr_t child_table_dma_addr );
π ARGUMENTS π
entryβ the target raw level 1 page table entry. This is the little slot you're writing into. πchild_table_dma_addrβ the DMA address of the level 0 page table that gets associated withentry. This one has requirements, bestie β see below. π«Ά
πΈ DESCRIPTION πΈ
When you call this function, child_table_dma_addr must be a valid DMA address, and it must be a multiple of 4 KiB. That is a hard requirement, not a suggestion. Do not try to sneak in a weird address and hope the vibe check passes. π
