STRUCT NAND_CONTROLLER(9)

🌸 NAME 🌸

struct nand_controller — okay bestie, this is the structure used to describe a NAND controller, straight from the Kernel API Manual (struct nand_controller(9), hiii 👋). It’s giving “one struct to describe the controller” energy, and yes, we are going through every single member.

✨ SYNOPSIS ✨

Here’s the exact shape — no cap, character for character:

       struct nand_controller {
           struct mutex lock;
           const struct nand_controller_ops *ops;
           struct {
             unsigned int data_only_read: 1;
             unsigned int cont_read: 1;
           } supported_op;
           bool controller_wp;
        };

🎀 Members 🎀

• lock — the lock used to serialize accesses to the NAND controller. One at a time, bestie; no chaotic parallel-access energy 💅
• ops — the NAND controller operations. Yep, the ops. Iconic.
• supported_op — the NAND controller known-to-be-supported operations; this one is only writable by the core after initial checking. No random writes, okay? 🫶
  • supported_op.data_only_read — the controller supports reading more data from the bus without restarting an entire read operation nor changing the column. That’s the whole mood ✨
  • supported_op.cont_read — the controller supports sequential cache reads. Cute and sequential, we love that.
• controller_wp — the controller is in charge of handling the WP pin. Main character energy for that pin 👑
