 * `i915` (upstream): official upstream kernel driver for older Intel client GPUs. Included in the common Linux distributions like Ubuntu.
 * `xe`: official upstream kernel driver for the latest (Xe2 or newer architecture) Intel GPUs.
 
-Although given KMD may seem to work fine also on other hardware (HW), it's validated only for [hardware it officially supports](https://dgpu-docs.intel.com/devices/hardware-table.html), and can have problems on others. User-space APIs also differ between these KMDs, so care should taken to use in a container an User Space Driver (UMD) matching to the underlying KMD on the host.
