ppc440spe_dma_put_desc(9)
π ppc440spe_dma_put_desc(9) β the Kernel API Manual girlies rise
okay so first things first, bestie: this page lives in section 9 of the Kernel API Manual, and it's literally the entire manual for ppc440spe_dma_put_desc. it's a little one. a snack-sized manpage. but we're gonna treat it with respect because that's the vibe β¨
πΈ NAME πΈ
ppc440spe_dma_put_desc β put DMA0,1 descriptor to FIFO. called with irqs disabled.
that's it. that's the whole name section. and yes, "irqs disabled" is doing a LOT of heavy lifting in that sentence, so if you're calling this with interrupts enabled you need to stop and think about your choices, queen π
π¦ SYNOPSIS π¦
void ppc440spe_dma_put_desc (struct ppc440spe_adma_chan *chan , struct
ppc440spe_adma_desc_slot *desc );
returns void β so like, no report card, no grade, it just does the thing and leaves π
π ARGUMENTS π
chanβ undescribed β no cap, the manpage literally does not describe it. that's not me being lazy, that's the source material being mysterious and giving main character energy πdescβ undescribed β same situation, bestie. the docs said "you figure it out" and honestly? iconic of them.
lowkey obsessed with a manpage that just hands you two pointers and a dream π«Ά
