mlx5hws_is_supported(9)

💖 mlx5hws_is_supported(9) — from the Kernel API Manual, bestie 💖

okay so real talk, this is a kernel API page and it's genuinely one of the shortest ones you will ever meet, so like… enjoy it? it's giving "little function, big job" energy ngl 🎀

---

✨ NAME ✨

mlx5hws_is_supported — the vibe-check function. it straight up checks whether HWS is supported, periodt.

---

🌸 SYNOPSIS 🌸

bool mlx5hws_is_supported (struct mlx5_core_dev *mdev );

like, that's it. that's the whole signature. so clean, so minimal, main character energy fr 💅

---

🦋 ARGUMENTS 🦋

• mdev — the device you want to check. that's the whole assignment, bestie. hand it the device, let it do its thing 🫶

---

⭐ RETURN ⭐

• true — if it's supported. slay, you're good to go ✨
• false — if it's not. no cap, that's the whole answer 😭

this one returns a plain bool, so don't go looking for an error code or anything fancy. it either is or it isn't, iykyk 💀
