✨ stm32_hash_set_nblw ✨

Okay bestie, welcome to the Kernel API Manual 💖 — this one's a tiny little page from the crypto corner of the kernel, and it's literally just one job: telling the STM32 hash hardware how many bytes in that final word actually count. No cap. 🎀

🌸 NAME 🌸

stm32_hash_set_nblw — set the number of valid bytes in the last word. 💅

🦋 SYNOPSIS 🦋

void stm32_hash_set_nblw (struct stm32_hash_dev *hdev , int length );

👑 ARGUMENTS 👑

• hdev — the stm32_hash_dev device. Like, the device. The main character we're operating on. 🫶
• length — the length of the final word. That's the vibe check for the last word — how long it is. 📏

🌈 SEE ALSO 🌈

• Kernel file ./drivers/crypto/stm32/stm32-hash.c — the whole source file, go read it iykyk 🧚
• stm32_hash_wait_busy(9)
• stm32_hash_write_ctrl(9)

Two functions in the same family, and honestly they're both iconic. Go say hi. 💜

And that's the whole page, bestie — short and slay. ✨ This little beauty lives under ./drivers/crypto/stm32, and it's dated October 2026, so yes, it's from the future and it's thriving. 🦋💖🎀
