🔥 firmware_data_write(9) 🔥

okay so bestie, you're in the Kernel API Manual and this page is literally about firmware_data_write — the write method for firmware. it's giving sysfs write energy, no cap 💅

---

✨ NAME ✨

firmware_data_write — write method for firmware 🫶

---

🌸 SYNOPSIS 🌸

       ssize_t firmware_data_write (struct file *filp , struct kobject *kobj ,
       const struct bin_attribute *bin_attr , char *buffer , loff_t offset ,
       size_t count );

---

🎀 ARGUMENTS 🎀

• filp — the open sysfs file, bestie. that's the file pointer in question ✨
• kobj — the kobject for the device. yes ma'am, device stuff 🦋
• bin_attr — the bin_attr structure. iconic binary-attribute behavior 💫
• buffer — the buffer being written. the actual data vibes 🍓
• offset — the buffer offset for write in total data store area. like, where exactly in the big data pile we're dropping this 👀
• count — the buffer size. how much we're writing, periodt 💅

---

🦋 DESCRIPTION 🦋

Data written to the 'data' attribute will be later handed to the driver as a firmware image. that's the whole plot, bestie — the driver gets the firmware image later, and this write method is doing its main character thing 💖
