okay so this is the ppc440spe_desc_init_dma2pq(9) page from the Kernel API Manual, bestie β and the whole vibe is βinitialize the descriptor for PQ operation in DMA2 controller.β Thatβs the tea. β¨
πΈ NAME πΈ
ppc440spe_desc_init_dma2pq β initialize the descriptor for a PQ operation in the DMA2 controller. periodt. π
β¨ SYNOPSIS β¨
void ppc440spe_desc_init_dma2pq (struct ppc440spe_adma_desc_slot *desc ,
int dst_cnt , int src_cnt , unsigned long flags );
π ARGUMENTS π
ngl bestie, the original page is giving us nothing for these β every single one literally says -- undescribed --. So weβre not inventing lore, okay? Hereβs exactly whatβs there, plus the types straight from the synopsis so you at least know the shape of it. π«Ά
