ppc440spe_a..._xor_set_src(9)

✨ NAME ✨

okay so this is the Kernel API Manual page for ppc440spe_a..._xor_set_src(9), bestie 💅 and the full-name main character is ppc440spe_adma_memcpy_xor_set_src — its whole thing is set source address into descriptor. that's the name tea, no cap 🫶

✨ SYNOPSIS ✨

void ppc440spe_adma_memcpy_xor_set_src (struct ppc440spe_adma_desc_slot
*sw_desc , dma_addr_t addr , int index );

yep, it returns void — no return-value gossip here, just vibes and a descriptor glow-up ✨

✨ ARGUMENTS ✨

the manpage is giving mystery on purpose: every argument is literally marked -- undescribed --, so we are not inventing lore, periodt 🙈

• sw_desc — -- undescribed -- in the source; the synopsis types it as struct ppc440spe_adma_desc_slot * 🎀
• addr — -- undescribed -- too; synopsis says dma_addr_t 📌
• index — also -- undescribed --; synopsis says int 🧚

bestie, the description slot is empty. we respect the empty slot. 💀
