megasas_issue_polled(9)

🎀 megasas_issue_polled(9) 🎀

okay bestie, welcome to the megasas_issue_polled(9) page from the Kernel API Manual. this one is short and iconic: it’s all about issuing a polling command, and there’s literally one MFI requirement you cannot skip. 💅

🌸 NAME 🌸

megasas_issue_polled — Issues a polling command ✨

🦋 SYNOPSIS 🦋

int megasas_issue_polled (struct megasas_instance *instance , struct
       megasas_cmd *cmd );

🍓 ARGUMENTS 🍓

• instance — Adapter soft state. this is your adapter’s soft-state bestie 🫶
• cmd — Command packet to be issued. the actual command packet going out 💌

💜 DESCRIPTION 💜

okay so for polling, MFI requires the cmd_status to be set to MFI_STAT_INVALID_STATUS before posting. that’s the requirement, no cap. set it before posting and you’re matching the MFI vibe check. 💅
