adf_bank_state_restore(9)

💅 adf_bank_state_restore — a Kernel API Manual moment (section 9, bestie)

okay so we're in the Kernel API Manual today, section 9, and the main character is adf_bank_state_restore. it's giving "put the bank back the way it was" energy and honestly? we love a restorative queen 🎀

✨ NAME ✨

adf_bank_state_restore — restore state of bank-related registers 🫶

---

🌸 SYNOPSIS 🌸

int adf_bank_state_restore (struct adf_accel_dev *accel_dev , u32
bank_number , struct adf_bank_state *state );

literally just those three things and it's a wrap ✨

---

🦋 ARGUMENTS 🦋

• accel_dev — Pointer to the device structure 💖 (the device we're doing all this for, obviously)
• bank_number — Bank number 🔢 (which bank, bestie — you gotta say which one)
• state — Pointer to bank state structure 🎀 (the whole vibe we're restoring to)

---

👑 DESCRIPTION 👑

so what does it do?? this function attempts to restore the state of a bank by writing the bank CSRs to the values in the state structure 🔥 like, it reaches into state, grabs the values, and writes them into the bank CSRs so the bank goes back to how it was. no cap, that's the whole plot.

Returns 0 on success, error code otherwise 👏 so like — 0 means slay, anything else means something went sideways and you get an error code instead. it's giving "check the return value, i'm begging you" 😭
