spi_mem_supports_op(9)

💅 spi_mem_supports_op(9) 💅

okay so this is from the Kernel API Manual, and bestie, it's literally the vibe check for SPI memory operations. yes we're doing this. 🎀

---

✨ NAME ✨

spi_mem_supports_op — checks if a memory device and the controller it's connected to actually support a specific memory operation 🫶

---

🌸 SYNOPSIS 🌸

bool spi_mem_supports_op (struct spi_mem *mem , const struct spi_mem_op
*op );

---

🦋 ARGUMENTS 🦋

• mem — the SPI memory, aka the device in question 💖
• op — the memory operation you wanna check, like "can we do this or not" 👀

---

🔥 DESCRIPTION 🔥

ngl, this is where it gets real. Some controllers are only supporting Single or Dual IOs — that's just their whole thing. Others might only support specific opcodes. And sometimes it's even the case that the controller and device both support Quad IOs but the hardware prevents you from using it because only 2 IO lines are connected. tragic, honestly. 😭

So this function checks whether a specific operation is supported. that's it. that's the whole job. main character energy fr fr ✨

---

⭐ RETURN ⭐

• true if op is supported 💜
• false otherwise 💀
