pvrdma_modify_srq(9)

💅 pvrdma_modify_srq(9) — from the Kernel API Manual, bestie 🎀

okay so like. this is a page from the Kernel API Manual and it's about pvrdma_modify_srq, which is lowkey the glow-up function for a shared receive queue. it changes the SRQ's attributes. that's the whole vibe. let's get into it ✨

✨ NAME ✨

pvrdma_modify_srq — modify shared receive queue attributes 🦋

like literally, you're editing the attributes of a shared receive queue. main character function behavior only 👑

---

🌸 SYNOPSIS 🌸

int pvrdma_modify_srq (struct ib_srq *ibsrq , struct ib_srq_attr *attr ,
enum ib_srq_attr_mask attr_mask , struct ib_udata *udata );

okay so it takes in an ib_srq *, an ib_srq_attr *, an enum ib_srq_attr_mask, and an ib_udata *, and it hands you back an int. that's the whole cast of characters, and yes they're all iconic in their own way 💖

🫶 ARGUMENTS 🫶

• ibsrq — the shared receive queue to modify 💫 this is the one getting the makeover, the subject of the whole episode
• attr — the shared receive queue's new attributes ✨ this is the new fit. the new look. the new stats, for the SRQ in question
• attr_mask — attributes mask 🎀 it tells you which of the attributes are in play, iykyk
• udata — user data 🌸 the user data that rides along with the call

---

🔥 DESCRIPTION 🔥

ngl the description here is short and sweet and honestly it ate:

returns 0 on success, otherwise returns an errno. periodt. 💀

so like, 0 means slay, you did it, the SRQ attributes are modified. anything else is an errno telling you what went sideways 😭 no cap, that's the entire documented behaviour.

fr fr: 0 = success, anything else = an errno. that's the whole contract bestie, don't overthink it 💅

• pvrdma_create_srq(9) — where the SRQ gets born ✨
• pvrdma_destroy_srq(9) — where it says bye 💀

it's giving full SRQ lifecycle, honestly. create her, query her, modify her, destroy her. the whole character arc 🌈
