🌸 NAME 🌸

okay so welcome to the Kernel API Manual, bestie — this page is all about wx_get_pcie_msix_counts(9), and its whole thing is literally Gets MSI-X vector count ✨

✨ SYNOPSIS ✨

int wx_get_pcie_msix_counts (struct wx *wx , u16 *msix_count , u16
       max_msix_count );

🎀 ARGUMENTS 🎀

• wx — pointer to hardware structure, aka the hardware struct main character 🫶
• msix_count — number of MSI interrupts that can be obtained, the count bestie 💅
• max_msix_count — number of MSI interrupts that mac need, like the mac's requested number 👑
