resource_validate_probe_set(9)

💅 resource_validate_probe_set(9) — a Kernel API Manual moment

okay so bestie, welcome to the Kernel API Manual ✨ and today's main character is resource_validate_probe_set — the function that looks at your probe descriptor set and is like "hmm, will the ASIC actually do this?" 🎀

---

🌸 NAME 🌸

resource_validate_probe_set — validate a probe descriptor set against the ASIC. That's it, that's the whole vibe check 💅

---

🦋 SYNOPSIS 🦋

enum dc_status resource_validate_probe_set (struct dc *dc , const struct
dc_probe_state *probes , uint8_t probe_count );

---

✨ ARGUMENTS ✨

• dc — the DC instance, aka the one handing you the HWSS capability hooks 🫶 it's giving "here's what the hardware can actually do" energy
• probes — the desired probe descriptors, i.e. the probe set you're manifesting 🔥
• probe_count — the number of valid entries in probes. note the word valid bestie, we're not out here counting garbage 🙈

---

💖 RETURN 💖

DC_OK if it's achievable 😌 otherwise a DC error 😭 no cap, that's the whole deal.
