drm/vmwgfx: Support the NOP_ERROR command
Can be used by user-space applications to test and verify the kernel
command buffer error recovery functionality.
Malicious user-space apps could potentially use this command to slow down
graphics processing somewhat, but they could also accomplish the same thing
using a random malformed command so this should be considered safe.
At least as safe as it gets.
