sas_end_device_alloc(9)

💅 sas_end_device_alloc(9) — like, the kernel API manual, bestie ✨

okay so picture this: you're deep in the kernel API manual (that's the 9 section, iykyk) and you need a remote PHY for an end device. this page is exactly that. welcome 🫶

---

🌸 NAME 🌸

sas_end_device_alloc — allocate an rphy for an end device. that's the whole vibe. it makes the thing. 💖

---

✨ SYNOPSIS ✨

struct sas_rphy * sas_end_device_alloc (struct sas_port *parent );

that's it. one function, one argument, one dream. 🌈

---

🎀 ARGUMENTS 🎀

• parent — which port. like, which port, bestie. the one the new thing gets attached to. 👑

---

💅 DESCRIPTION 💅

so what it does is: allocates an SAS remote PHY structure, connected to parent. that's the tea. it hands you back a shiny new rphy that's already wired up to the port you passed in. no cap. ⭐

---

🔥 RETURN 🔥

you get the SAS PHY allocated — or NULL if the allocation failed. 😭 so like, always check your return value, fr fr. if it's NULL, that's the allocation going 💀 and you gotta handle it.

ok real talk: parent is a struct sas_port * and this returns a struct sas_rphy *. keep those straight and you're golden. 💜

that's the whole page, bestie. go allocate something iconic. mwah 💋

this lil masterpiece lives in ./drivers/scsi, dated October 2026 — and it's sas_end_device_alloc(9), obviously. periodt. 👑✨
