vmw_dma_select_mode(9)

💖 NAME 💖

okay so this page is vmw_dma_select_mode(9) from the Kernel API Manual, and it's literally about figuring out how DMA mappings should be set up for this system. 💅

✨ SYNOPSIS ✨

int vmw_dma_select_mode (struct vmw_private *dev_priv );

🎀 ARGUMENTS 🎀

• dev_priv — pointer to a struct vmw_private. That's the whole input, bestie, no cap 🫶

🦋 DESCRIPTION 🦋

So this function is out here trying to determine what actions the driver needs to take to make system pages visible to the device. 👀✨

If it decides DMA is not possible, it returns -EINVAL. Then the driver may try to disable features of the device that require DMA. 💀
