Hi
I enabled DMAR by kernel parameter, and started X windows.
The following error message is reported forever.
Is this driver's issue?

yeah it looks like the driver isn't using the DMA mapping API correctly.
You filed this bug in the wrong forum though, this isn't the nvidia
forum, and you're using their binary driver, nothing we can do to help
you.
