XSDFEC_GET_STATS(9)

💅 XSDFEC_GET_STATS 💅

okay so bestie, welcome to the XSDFEC_GET_STATS page — it lives in the Kernel API Manual and it's honestly kind of a vibe. it's a tiny little ioctl page but it ATE, fr fr. let's get into it 🎀

✨ Parameters ✨

• struct xsdfec_stats * — this is a pointer to the struct xsdfec_stats that will contain the updated stats values. yes, updated — it's gonna get filled in with the fresh numbers, so hand it a struct to live in 🫶

🌸 Description 🌸

it's an ioctl that returns SD-FEC core stats. that's the whole thing. iconic, honestly 💅

but — and this is the important part, no cap — this can only be used when the driver is in the XSDFEC_STOPPED state. so do a vibe check on your state first, bestie, because if the driver isn't stopped this is not the moment 😭

okay so like. XSDFEC_STOPPED only. i'm not gonna say it a third time. (i might say it a third time. XSDFEC_STOPPED. there. 🦋)
