[PATCH v2 0/2] drm/ttm: Add an option to report graphics memory OOM
...host-memory (system memory). Add a device init flag to
have -ENOSPC propagated from the resource managers instead of being
converted to -ENOMEM, to aid driver stacks in determining what
error code to return or whether corrective action can be taken at
the driver level.
The first patch deals with a ttm_device_init() interface change,
The Second patch adds the actual functionality.
A follow-up will be posted for Xe once this is merged / backmerged.
