adf_isr_resource_alloc(9)

✨ adf_isr_resource_alloc ✨

okay so bestie, welcome to the Kernel API Manual 💅 this is the adf_isr_resource_alloc(9) page and it's literally the glow-up your acceleration device's interrupt game has been waiting for. buckle up 🎀

---

🌸 NAME 🌸

adf_isr_resource_alloc — the function that grabs an IRQ for your acceleration device, no cap 🫶

---

🦋 SYNOPSIS 🦋

int adf_isr_resource_alloc (struct adf_accel_dev *accel_dev );

like, that's the whole signature. iconic. she's short and she knows it ✨

---

🎀 ARGUMENTS 🎀

• accel_dev — a pointer to the acceleration device. that's it. that's the whole argument. she takes exactly one (1) pointer and she's not sorry about it 💅

---

💖 DESCRIPTION 💖

so what does she even do? the function allocates interrupts for the acceleration device — like, it goes and gets the IRQ situation sorted so your device can actually get attention when it needs it 🔥 main character energy fr fr.

you hand her the accel_dev pointer, she handles the interrupt allocation. simple. clean. slay.

---

⭐ RETURN ⭐

• 0 on success — we love a zero, zero means yes, zero is the good number 🎉
• an error code otherwise — not zero, so like... something went sideways, bestie 😭 check that code and go fix it

🌈 SEE ALSO 🌈

• Kernel file ./drivers/crypto/intel/qat/qat_common/adf_isr.c — the actual source, go read her, she's right there 🧚
• adf_isr_resource_free(9) — the bestie who undoes all of this. every alloc needs their free, balance, periodt 💜
• adf_init_misc_wq(9) — another one from the same friend group, go say hi 🌸

---

ngl this one's a short page but she's still important — you can't just malloc an IRQ and dip, you have to actually free it later with adf_isr_resource_free(9) 🙈

---

and that's the page, babes 🎀💖 cute little sign-off: this beauty comes from the source file ./drivers/crypto/intel/qat/qat... and she's dated October 2026 ⭐ go forth and allocate responsibly 🦋👑
