megasas_fire_cmd_gen2(9)

💅 NAME 💅

Okay bestie, you found it: megasas_fire_cmd_gen2(9) from the Kernel API Manual. Its whole job? Sends command to the FW. That's the name, that's the vibe, no cap. ✨

🎀 SYNOPSIS 🎀

void megasas_fire_cmd_gen2 (struct megasas_instance *instance ,
dma_addr_t frame_phys_addr , u32 frame_count , struct
megasas_register_set __iomem *regs );

Return type is void, so it's giving “do the thing and don't hand me a value back” energy. 💅

🦋 ARGUMENTS 🦋

Here's the squad it takes, one by one:

• instance — adapter soft state. Your main character struct for this adapter, iykyk. 👑
• frame_phys_addr — physical address of cmd. Literally where the command lives in physical memory. 📍
• frame_count — number of frames for the command. Count 'em, bestie. 🔢
• regs — MFI register set. The register set it gets to play with. 🎛️
