mlx4_en_phc_enable(9)

💅 NAME 💅

ok so bestie, welcome to the mlx4_en_phc_enable page — this is the mlx4_en_phc_enable(9) situation, from the Kernel API Manual (yes the manual name goes here, slay). what does it do? it enables or disables an ancillary feature. that's the whole vibe. keep reading tho 🫶

---

✨ SYNOPSIS ✨

int mlx4_en_phc_enable (struct ptp_clock_info *ptp , struct
       ptp_clock_request *request , int on );

like, that's the signature. copy it exactly, don't come for me 💀

---

🎀 ARGUMENTS 🎀

• ptp — the ptp clock structure. yes queen, the clock struct, it's giving main character ✨
• request — the desired resource to enable or disable. whatever it is you're trying to turn on (or off, no judgement)
• on — the caller passes one to enable, or zero to disable. 1 = slay, 0 = not slay. simple as that 🔥

---

🌸 DESCRIPTION 🌸

okay so the actual tea: this function enables (or disables) ancillary features of the PHC subsystem. iconic. BUT — and this is the important part, no cap — currently, no ancillary features are supported. literally none. zero. the feature list is empty. it's giving "we made the door but there's no room behind it" 😭🙈

so like, it exists, it takes your args, it goes in the request/on pipeline... and there's nothing on the other side yet. that's not a bug, that's just the current state, fr fr 💜

ngl the "no ancillary features are supported" line is the whole plot twist here. don't forget it. it's load-bearing 💅
