β¨ ppc440spe_desc_init_xor β¨
okay so bestie, welcome to the Kernel API Manual π β this is the page for ppc440spe_desc_init_xor(9), and it does exactly one iconic thing: it initializes the descriptor for an XOR operation. that's it, that's the whole vibe. lowkey a one-job queen π
πΈ NAME πΈ
ppc440spe_desc_init_xor β initialize the descriptor for XOR operation β¨
π¦ SYNOPSIS π¦
void ppc440spe_desc_init_xor (struct ppc440spe_adma_desc_slot *desc ,
int src_cnt , unsigned long flags );
it returns void, so no cap, there's literally nothing coming back to you. it's giving "do the thing and dip" π
π ARGUMENTS π
descβ -- undescribed --src_cntβ -- undescribed --flagsβ -- undescribed --
okay so about these threeβ¦ the source page literally just says -- undescribed -- for every single one of them π like the docs said "you'll figure it out" and then left the group chat. i'm not gonna invent lore that isn't there, so: desc, src_cnt, and flags are the arguments, and that is genuinely all this page tells us. no notes. no elaboration. iconic in a mysterious way, honestly π«Ά
bestie, please don't @ me about the missing descriptions β i'm just the messenger π§

and that's the page, bestie π this little love letter lives in ./drivers/dma/ppc4xx, dated October 2026 β so yeah, future-coded of her. take care, drink water, and may your descriptors always be initialized π¦π
