pds_client_adminq_cmd(9)

🎀 pds_client_adminq_cmd(9) 🎀

okay bestie, welcome to the Kernel API Manual — more specifically, section 9 of it, and more specifically than that, we're talking about pds_client_adminq_cmd. yeah. the whole name. she's long but she's worth it 💅

---

✨ NAME ✨

pds_client_adminq_cmd — the function that processes an adminq request for the client. that's it, that's the vibe 🦋

---

🌸 SYNOPSIS 🌸

int pds_client_adminq_cmd (struct pds_auxiliary_dev *padev , union
pds_core_adminq_cmd *req , size_t req_len , union pds_core_adminq_comp
*resp , u64 flags );

she returns an int, she takes five args, and yes you have to remember all of them 💀

---

🫶 ARGUMENTS 🫶

• padev — ptr to the client device. like, the actual device object. don't lose her 🙈
• req — ptr to the buffer holding your request 👑
• req_len — the length of the actual struct being used for the request, not the vibe of it, the real length fr fr
• resp — ptr to the buffer where the answer gets copied. she's empty until Core fills her in 🍓
• flags — optional flags, and they come from pds_core_adminq_flags. optional! cute! ✨

---

⭐ RETURN ⭐

0 on success, or negative for error. so basically: zero = slay, negative = 😭

---

💖 DESCRIPTION 💖

okay so here's the little sequence of events, and honestly it's giving choreography:

• Client sends pointers to the request and response buffers
• Core copies request data into pds_core_client_request_cmd
• Core sets other fields as needed
• Core posts to AdminQ
• Core copies completion data into the response buffer

that's the whole flow, no cap. you hand over the pointers, Core does the actual work, everybody goes home 🧚

---

🔥 SEE ALSO 🔥

• Kernel file ./drivers/net/ethernet/amd/pds_core/auxbus.c
• pds_client_register(9)
• pds_client_unregister(9)

both of those are 9 sections too, so you know they're part of the same little friend group 🌈

---

ngl this one is short and sweet, but don't skip the details — req_len is the actual struct length and flags are optional flags from pds_core_adminq_flags. details are the moment 💅

okay that's the whole page, love u, go read the source 🫶 this little number lives in ./drivers/net/ethernet/amd/pds… (the kernel source tree, you know the one) and the version/date stamp on it is October 2026 — iconic, future-dated, obsessed ⭐👑
