VMW_DEBUG_USER(9)

💖 VMW_DEBUG_USER(9) 💖

okay bestie, this is the VMW_DEBUG_USER(9) page from the Kernel API Manual, and it’s giving “kernel macro but make it user-space debug.” no cap, it’s a macro, and we’re gonna read it together 💅✨

✨ NAME ✨

VMW_DEBUG_USER — Debug output for user-space debugging. That’s literally the whole vibe: user-space debug output, but from the kernel side 🫶

🌸 SYNOPSIS 🌸

VMW_DEBUG_USER (fmt , ... );

🎀 ARGUMENTS 🎀

• fmt — a printf like format string. Yes bestie, that kind of format string 💖
• ... — variable arguments. The extra lil’ args that go with the format ✨

🦋 DESCRIPTION 🦋

This macro is for logging user-space error and debugging messages — for example, command buffer execution errors due to malformed commands, invalid context, etc. So if the command buffer is being messy because a command is malformed or the context is invalid, this is the macro doing the logging, fr fr 😭👑
