=== NVHOST_IOCTL_CHANNEL_GET_SYNCPOINT ===
Returns the current syncpoint value for a given module. Identical to Linux driver.

__in u32 module_id;
__out u32 syncpt_value;
};
=== NVHOST_IOCTL_CHANNEL_GET_WAITBASE ===
Returns the current waitbase value for a given module. Always returns 0.
struct {
__in u32 module_id;
__out u32 waitbase_value;
};
