cmdq_pkt_write_mask_pa(9)

🎀 NAME 🎀

okay so bestie, welcome to the cmdq_pkt_write_mask_pa(9) page — yes, that’s the manual name, and it’s lowkey iconic. This one is all about cmdq_pkt_write_mask_pa — append a write command with a mask to the CMDQ packet with pa. Main character energy for CMDQ packet writes, no cap. ✨

✨ SYNOPSIS ✨

Here’s the exact signature, copied with love:

int cmdq_pkt_write_mask_pa (struct cmdq_pkt *pkt , u8 subsys , u32
       pa_base , u16 offset , u32 value , u32 mask );

💖 ARGUMENTS 💖

• pkt — the CMDQ packet. That’s the thing you’re appending to, bestie.
• subsys — unused parameter. Not me pointing out that it’s literally unused, but yes: it’s unused. 💀
• pa_base — the physical address base of the hardware register.
• offset — register offset from CMDQ sub system.
• value — the specified target register value.
• mask — the specified target register mask.

🌈 RETURN 🌈

Returns 0 for success; else the error code is returned. Zero means slay, and anything else is the error code coming through. periodt. 💅
