Mali errors on Xen

vik436

Hi,

We are using Xen hypervisor on Hikey960 board with Debian as Dom0 and Android as DomU. We has created passthrough node for GPU so that it is exclusive for DomU Android. On booting DomU mali drivers are loaded successfully and able to see /dev/mali0, but getting below errors continuously.
