💅 ppc440spe_adma_prep_dma_xor ✨

okay so bestie, welcome to the Kernel API Manual page for ppc440spe_adma_prep_dma_xor — it's giving “prepare CDB for a XOR operation,” and honestly the name already ate. 🫶

🌸 NAME 🌸

ppc440spe_adma_prep_dma_xor — prepare CDB for a XOR operation.

⭐ SYNOPSIS ⭐

struct dma_async_tx_descriptor * ppc440spe_adma_prep_dma_xor (struct
dma_chan *chan , dma_addr_t dma_dest , dma_addr_t *dma_src , u32 src_cnt
, size_t len , unsigned long flags );

🎀 ARGUMENTS 🎀

okay bestie, the source is literally not giving us descriptions for these — every single one says -- undescribed --, so I’m not gonna invent lore. no cap. 🙈

• chan — -- undescribed --
• dma_dest — -- undescribed --
• dma_src — -- undescribed --
• src_cnt — -- undescribed --
• len — -- undescribed --
• flags — -- undescribed --
