qed_mcp_nvm_read(9)

🌸 NAME 🌸

okay so bestie, this is qed_mcp_nvm_read(9) from the Kernel API Manual, and it is literally here to Read from NVM. ✨ no cap.

🦋 SYNOPSIS 🦋

int qed_mcp_nvm_read (struct qed_dev *cdev , u32 addr , u8 *p_buf , u32
       len );

🎀 ARGUMENTS 🎀

• cdev — Qed dev pointer. like, the qed device you're working with 💅
• addr — NVM offset. where in NVM we're reading from 🫶
• p_buf — NVM read buffer. the buffer the read lands in 🍓
• len — Buffer len. how big that buffer is 💖

🔥 RETURN 🔥

Int - 0 - Operation was successul.

so yeah, it returns an int, and 0 means the operation was successful. and yes, “successul” is exactly how it's spelled on the page — I'm not fixing it, periodt 💅

🌈 SEE ALSO 🌈
