ice_discover_flash_size(9)

💖 NAME 💖

okay so bestie, meet ice_discover_flash_size(9) from the Kernel API Manual — her whole thing is to discover the available flash size. iconic behavior, no cap. ✨

---

🦋 SYNOPSIS 🦋

int ice_discover_flash_size (struct ice_hw *hw );

---

🎀 ARGUMENTS 🎀

• hw — pointer to the HW struct. that's the whole argument, bestie, she's lowkey low-maintenance. 🫶

---

🌸 DESCRIPTION 🌸

so the device flash could be up to 16MB in size — yes, big flash energy — but it is possible that the actual size is smaller. 👀

the move is to use bisection to determine the accessible size of flash memory. periodt. that's the vibe, and we are not inventing extra steps. 💅
