💅 generic_NCR5380_precv(9)

okay so bestie, welcome to the Kernel API Manual — this is the page for generic_NCR5380_precv, and it's lowkey a little legend. it's giving "small function, big job." let's get into it ✨

---

🌸 NAME 🌸

generic_NCR5380_precv — pseudo DMA receive

like, it receives stuff. with pseudo DMA. iconic behaviour, no cap 💖

---

✨ SYNOPSIS ✨

int generic_NCR5380_precv (struct NCR5380_hostdata *hostdata , unsigned
char *dst , int len );

that's the whole signature, copy it exactly, don't @ me 🫶

---

🎀 ARGUMENTS 🎀

so there's three of them and each one has main character energy in its own way:

• hostdata — the scsi host's private data. it's the personal stash, the vibes closet, the struct NCR5380_hostdata * that knows all the host's business 💜
• dst — the buffer you're writing into. unsigned char *, and yes it's the destination, hence the name — she's literally called dst 💅
• len — the transfer size. an int. it's how much we're moving, so be normal about it 🙈

---

🦋 DESCRIPTION 🦋

okay so the actual tea: this does a pseudo DMA mode receive from a 53C400 or equivalent device.

that's it. that's the whole bit. pseudo DMA. receive. 53C400 or equivalent. periodt 🔥

ngl, if you were hoping for a plot twist — there isn't one. the description is short and she knows it. still slay tho 💀

🌈 SEE ALSO 🌈

go touch some other docs, bestie:

• the kernel file ./drivers/scsi/g_NCR5380.c 👑
• g_NCR5380_probe_irq(9) — the sibling that probes IRQs 🔍
• generic_NCR5380_psend(9) — the send counterpart, because every precv needs a psend fr fr 🎀

and that's a wrap, bestie! this page lives in ./drivers/scsi and it's dated October 2026 — so go forth, receive your pseudo DMA, and remember: you're doing amazing, sweetie 🧚‍♀️💖✨
