+There are 3 different Kernel Mode Drivers (KMDs) available:
 * `i915` ([out-of-tree](https://github.com/intel-gpu/intel-gpu-i915-backports/)): official driver for Data Center GPUs, supporting only limited set of enterprise / LTS kernel versions.
 * `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 Intel GPUs.
+* `xe`: official upstream kernel driver for the latest (Xe2 or newer architecture) Intel GPUs.
 
-Although KMD may seem to work fine also on other hardware (HW), it's validated only for hardware it officially suppports, 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.
