💖 validate_hb_ctrs_cnt(9) 💖

okay so first things first, bestie: we're deep in the Kernel API Manual section 9 today, and the star of the show is validate_hb_ctrs_cnt. yes it's a mouthful. yes it's iconic. let's get into it 🫶

---

✨ NAME ✨

validate_hb_ctrs_cnt — checks if the number of heartbeat counters should be updated by one to support the currently loaded firmware.

like, it's literally doing a vibe check on whether your heartbeat counter count needs a lil +1 because of whatever firmware is loaded rn 💅

---

🌸 SYNOPSIS 🌸

bool validate_hb_ctrs_cnt (struct adf_accel_dev *accel_dev );

she takes one argument and gives you back a bool. simple. elegant. main character energy 👑

---

🎀 ARGUMENTS 🎀

• accel_dev — Pointer to acceleration device. that's the whole thing, no cap. it's the device we're asking about 💖

---

🦋 RETURN 🦋

so there's basically two moods here, and she will tell you which one she's in:

• true — hb_ctrs must increased by ADF_NUM_PKE_STRAND 🔥 (yes, that's exactly how it's written in the original, we don't touch the wording of the facts, only the vibes ✨)
• false — no changes needed. nothing to do. she's chill. 😌

---

👑 SEE ALSO 👑

• Kernel file ./drivers/crypto/intel/qat/qat_common/adf_heartbeat.c — go read it, iykyk 🧚

---

ngl bestie, this one's short and sweet, but that does NOT mean you skip the details. true means the counter goes up by ADF_NUM_PKE_STRAND, false means hands off. periodt 💅

---

and that's the whole page, bestie! 🌈 this lil gem comes to you from the source/version line ./drivers/crypto/intel/qat/qat... dated October 2026, and yes the page is officially validate_hb_ctrs_cnt(9) — drink water, read your kernel source, slay 💜🍓
