It’s mostly up to the specific hardware and its host-side drivers. I’d say that GPU compute security is a very under-studied area compared with CPU compute.

- ArcVRArthur 4y agoYa, that's accurate. The precise driver implementation matters a lot. Having said that there are some good 'best practices' that seem to make a difference. In my opinion 'IOMMU Aware Mediated Device' could also make some much needed improvements here as it would allow for more granular IOMMU allocations - perhaps this mode could help further support the 'App VMs' use-case using shared work queues without breaking IO virtual address translation: https://lwn.net/ml/linux-kernel/20190222021927.13132-1-baolu.lu@linux.intel.com/ https://lwn.net/ml/linux-kernel/20190222021927.13132-1-baolu...
