add_update_sla(9)

💅 add_update_sla(9) — a Kernel API Manual moment 🎀

okay so bestie, welcome to the add_update_sla(9) page, it's giving kernel API manual energy and honestly we're obsessed. this is the doc for add_update_sla, and it's lowkey the whole vibe for how an SLA gets born and how it gets updated. two jobs, one function, main character energy fr fr. ✨

---

🌸 NAME 🌸

add_update_sla — handles the creation and the update of an SLA 💖

---

✨ SYNOPSIS ✨

int add_update_sla (struct adf_accel_dev *accel_dev , struct
       adf_rl_sla_input_data *sla_in , bool is_update );

---

🦋 ARGUMENTS 🦋

• accel_dev — pointer to acceleration device structure, like the actual hardware baddie we're talking to 🔥
• sla_in — pointer to user input data for a new/updated SLA, aka the lore the user is handing over 💅
• is_update — flag to indicate if this is an update or an add operation 🎀 (yes bestie, it's literally the "new or improved" toggle)

---

👑 RETURN 👑

the return values, no cap, every single one:

• 0 — ok 🌈 (slay)
• -ENOMEM — memory allocation failed 😭 (the malloc said no)
• -EINVAL — user input data cannot be used to create SLA 🙈 (the vibes were off)
• -ENOSPC — all available SLAs are in use 💀 (full, no room, periodt)

fr fr check these before you assume anything worked, bestie. 0 is the only "we ate" answer.

💖 cute little sign-off: this page lives at ./drivers/crypto/intel/qat/qat... and it's dated October 2026 — and the manual is add_update_sla(9), which we already knew but like, closure. bye bestie, go read some source 🫶⭐
