Hi, Jacob, > Kernel workqueues were disabled due to flawed use of kernel VA and SVA API. > Now That we have the support for attaching PASID to the device's default s/That/that/ > domain and the ability to reserve global PASIDs from SVA APIs, we can re-enable > the kernel work queues and use them under DMA API. > > We also use non-privileged access for in-kernel DMA to be consistent with the > IOMMU settings.
