qed_dbg_grc_config(9)

🦋 qed_dbg_grc_config 🦋

okay so this is a page straight out of the Kernel API Manual (yes, the kernel has a manual, and yes it's as iconic as it sounds 💅), and it's about one tiny function that sets a GRC parameter. lowkey niche, highkey useful. let's get into it bestie 🌸

---

✨ NAME ✨

qed_dbg_grc_config — sets the value of a GRC parameter. that's it. that's the whole vibe. 🎀

---

🌈 SYNOPSIS 🌈

enum dbg_status qed_dbg_grc_config (struct qed_hwfn *p_hwfn , enum
dbg_grc_params grc_param , u32 val );

like, look at her. three args, one return, zero drama (until the errors hit, we'll get there 🙈).

---

💖 ARGUMENTS 💖

• p_hwfn — HW device data. it's the hardware function handle, the main character of the whole qed show 👑
• grc_param — GRC parameter. which knob you're turning, basically.
• val — Value to set. the actual number going in. 💫

---

🔥 RETURN 🔥

returns an error if any of these happen, so pay attention bestie, no cap:

• The version wasn't set.
• Grc_param is invalid.
• Val is outside the allowed boundaries.

fr fr, that third one is the classic "you gave me a number that doesn't fit" situation 😭 so mind your boundaries.
