💖 ice_aq_read_nvm(9) — the kernel API manual, but make it cute 🎀

okay so bestie, welcome to the ice_aq_read_nvm page — it lives in the Kernel API Manual and it's genuinely iconic. grab a snack, we're reading the NVM together 🦋

✨ NAME ✨

ice_aq_read_nvm — yes, that's the whole name, and honestly? it ate. this is the function that reads the NVM using the admin queue commands (0x0701). main character energy fr fr 💅

🌸 SYNOPSIS 🌸

int ice_aq_read_nvm (struct ice_hw *hw , u16 module_typeid , u32 offset
, u16 length , void *data , bool last_command , bool read_shadow_ram ,
struct ice_sq_cd *cd );

that's the whole signature, copied exactly, no cap. seven arguments, one return int, let's get into it 👑

🫶 ARGUMENTS 🫶

  • hw — pointer to the HW struct. your hardware bestie, the whole context of the operation ✨
  • module_typeid — module pointer location in words from the NVM beginning. words, not bytes, bestie, don't mix it up 🙈
  • offset — byte offset from the module beginning. like an address but for how far into the module you're looking 🌸
  • length — length of the section to be read (in bytes from the offset). how much you're grabbing, in bytes 🎀
  • data — command buffer (size [bytes] = length). so the buffer has to be exactly as big as length bytes, that's the vibe check ✔️
  • last_command — tells if this is the last command in a series. like the final text in a group chat — flags when you're done 🫡
  • read_shadow_ram — tell if this is a shadow RAM read. yes, shadow RAM, very mysterious, very spooky-season 👻
  • cd — pointer to command details structure or NULL. pass NULL if you don't have one, it's literally fine 💜

🔥 DESCRIPTION 🔥

Read the NVM using the admin queue commands (0x0701). that's the whole lore — it reads the NVM, it does it through the admin queue commands, and the opcode is 0x0701. periodt 💅

ngl this one's short and sweet, so there's no chaos to warn you about — just keep your length matching your data buffer size and you're golden 🧚
