qla4_83xx_re...rite_crb_reg(9)

🌸 NAME 🌸

okay so bestie, welcome to the Kernel API Manual, page qla4_83xx_re...rite_crb_reg(9) — yes that's the actual truncated name, it's giving "my name got cut off in the group chat" energy, but we move 💅

qla4_83xx_read_write_crb_reg — read from raddr and write value to waddr. That's the whole gig. Two CRB addresses, one function, iconic behaviour.

✨ SYNOPSIS ✨

void qla4_83xx_read_write_crb_reg (struct scsi_qla_host *ha , uint32_t
raddr , uint32_t waddr );

no cap, that's the entire signature — void return, so it doesn't give you anything back, it just does the thing and leaves 🫶

🎀 ARGUMENTS 🎀

• ha — pointer to the adapter structure. literally the main character of this whole operation, everything else is just vibes without it 👑
• raddr — the CRB address to read from. this is where the info comes from 🦋
• waddr — the CRB address to write to. this is where the value goes, periodt 🌟
