ppc440spe_test_raid6(9)

🦋 ppc440spe_test_raid6(9) 🦋

okay so bestie, this is a page straight out of the Kernel API Manual ✨ it's called ppc440spe_test_raid6(9), and it's basically a little vibe check for RAID-6 capabilities. No cap 💅

🌸 NAME 🌸

ppc440spe_test_raid6 — this is the “test are RAID-6 capabilities enabled successfully” moment, bestie. For this we just perform one WXOR operation with the same source and destination addresses, and the GF-multiplier is 1; so if RAID-6 capabilities are enabled then we'll get src/dst filled with zero. That's the whole test, and it ate 🔥

✨ SYNOPSIS ✨

here's the signature, copy it exactly, iykyk:

int ppc440spe_test_raid6 (struct ppc440spe_adma_chan *chan );

🎀 ARGUMENTS 🎀

• chan — -- undescribed -- 😭 the page literally says undescribed, so I'm not gonna invent lore. It's the struct ppc440spe_adma_chan * from the signature, and that's all the tea we have 🍓

mwah 💋 before you go: the footer's source/version is ./drivers/dma/ppc4xx, and the date is October 2026. That's the whole page, bestie — go forth and test those RAID-6 capabilities 🫶✨
