xspi_dirmap_write(9)

🌸 NAME 🌸

okay bestie, meet xspi_dirmap_write(9) — straight from the Kernel API Manual — and it's literally the function for writing data to xspi memory. 💅

✨ SYNOPSIS ✨

ssize_t xspi_dirmap_write (struct device *dev , u64 offs , size_t len ,
       const void *buf );

🎀 ARGUMENTS 🎀

• dev — the xspi device. main character energy, obviously. 👑
• offs — offset. the starting spot, bestie.
• len — number of bytes to be written. yes, we're counting. 🍓
• buf — buffer holding write data. the data lives here. 🫶

🦋 DESCRIPTION 🦋

So this function writes data into xspi memory. That's the whole vibe. ✨

On success it returns the number of bytes written; otherwise it returns a negative errno. No cap — negative means something went sideways. 😭
