STRUCT FSL_MC_UAPI(9)

💖 struct fsl_mc_uapi(9) 💖

Okay so this is struct fsl_mc_uapi(9), bestie — straight from the Kernel API Manual ✨ and it's all about the info that comes with a device file. Periodt.

✨ SYNOPSIS ✨

Here's the struct in all its exact, character-for-character glory:

       struct fsl_mc_uapi {
           struct miscdevice misc;
           struct device *device;
           struct mutex mutex;
           u32 local_instance_in_use;
           struct fsl_mc_io *static_mc_io;
        };

🎀 Members 🎀

• misc — a struct miscdevice linked to the root dprc 🫶
• device — the newly created device in /dev 💅
• mutex — a mutex lock to serialize the open/release operations 🔒
• local_instance_in_use — local MC I/O instance in use or not 👀
• static_mc_io — pointer to the static MC I/O object 🎯

🌈 SEE ALSO 🌈
