pvr_mmu_get...ble_dma_addr(9)
β¨ pvr_mmu_get_root_table_dma_addr β¨
okay so before we even start β this page lives in the Kernel API Manual, and it's the whole entire manual page for pvr_mmu_get_root_table_dma_addr(9). One function. Four sections. Let's get into it bestie π
π NAME π
pvr_mmu_get_root_table_dma_addr β get the DMA address of the root of the page table structure behind a VM context. that's literally it, that's the whole job π«Ά
πΈ SYNOPSIS πΈ
dma_addr_t pvr_mmu_get_root_table_dma_addr (struct pvr_mmu_context *ctx
);
look at her go β¨ returns a dma_addr_t, takes one pointer, no drama.
π¦ ARGUMENTS π¦
ctxβ target MMU context. like, the specific context you want the root-table DMA address of. you bring the context, she brings the address π
