megasas_rea...s_reg_fusion(9)
π megasas_read_fw_status_reg_fusion β a Kernel API Manual moment π
okay so bestie, welcome to the Kernel API Manual β¨ this one is a tiny little function page and honestly it's giving "small but iconic." no cap.
πΈ NAME πΈ
megasas_read_fw_status_reg_fusion β literally just returns the current FW status value π
that's the whole job. she reads the firmware status register and hands you back what it says. main character energy for a getter, fr fr.
β¨ SYNOPSIS β¨
u32 megasas_read_fw_status_reg_fusion (struct megasas_instance *instance
);
so she takes one (1) argument and gives you back a u32 π the way that return type is right there at the front. we love a clear signature.
π¦ ARGUMENTS π¦
instanceβ the Adapter soft state π«Ά that's it, that's the whole input. hand her the adapter's soft state and she's good to go.
π SEE ALSO π
bestie there are SO many siblings, this function is not an only child π every single one of these is part of the same megaraid_sas fusion family β go say hi:

ok that's the whole page π«Ά short, sweet, and every flag accounted for. go read the fusion source file if you want the lore, it's all there.
sign-off time π this lil page lives in ./drivers/scsi/megaraid, dated October 2026, and yes the footer still says megasas_rea...s_reg_fusion(9) because the title got truncated and we're just living with it π slay. bye bestie, go read a register πβ¨
