🎀 igb_get_bus_info_pcie(9) 🎀

okay bestie, welcome to the Kernel API Manual page for igb_get_bus_info_pcie 💖 this is the little function that handles getting PCIe bus information, and we're gonna go through it together, no cap.

✨ NAME ✨

igb_get_bus_info_pcie — get PCIe bus information 🦋

💅 SYNOPSIS 💅

s32 igb_get_bus_info_pcie (struct e1000_hw *hw );

🫶 ARGUMENTS 🫶

• hw — pointer to the HW structure. that's it, that's the whole argument, she's simple and iconic 💅

🔥 DESCRIPTION 🔥

okay so what this function actually does: it determines and stores the system bus information for a particular network interface. literally the whole vibe is "figure out the bus deets and keep them." 💾✨

the following bus information is determined and stored:

• bus speed
• bus width
• type (PCIe)
• PCIe function

so yeah, it's giving "collect the PCIe lore and stash it in the HW structure." main character energy fr fr 🌸
