Hi guys,
while working through more old TTM functionality I stumbled over the io_reserve_lru.
Basic idea is that when this flag is set the driver->io_mem_reserve() callback can return -EAGAIN resulting in unmapping of other BOs.
But Nouveau doesn't seem to return -EAGAIN in the call path of io_mem_reserve anywhere.
So is this unused or am I missing something?
Regards, Christian.
