STRUCT ZYNQMP_IPI_MCHAN(9)

💖 NAME 💖

okay so bestie, welcome to the struct zynqmp_ipi_mchan(9) page from the Kernel API Manual 💅. This struct is literally the description of a Xilinx ZynqMP IPI mailbox channel — that’s the whole vibe, no cap. iconic ✨

✨ SYNOPSIS ✨

Here’s the struct in all its exact, copy-paste-safe glory:

       struct zynqmp_ipi_mchan {
           int is_opened;
           void __iomem *req_buf;
           void __iomem *resp_buf;
           void *rx_buf;
           size_t req_buf_size;
           size_t resp_buf_size;
           unsigned int chan_type;
        };

🎀 Members 🎀

Each member is doing its own main character thing:

• is_opened — indicate if the IPI channel is opened
• req_buf — local to remote request buffer start address
• resp_buf — local to remote response buffer start address
• rx_buf — receive buffer to pass received message to client
• req_buf_size — request buffer size
• resp_buf_size — response buffer size
• chan_type — channel type
