196 All of those are 32-bit integer values; the usual Linux kernel limits
200 object through a driver-specific ioctl, and can use that handle to refer
201 to the GEM object in other standard or driver-specific ioctls. Closing a

229 GEM also supports buffer sharing with dma-buf file descriptors through
230 PRIME. GEM-based drivers must use the provided helpers functions to
