[PATCH 0/5] crypto/uadk: introduce uadk crypto driver
by Zhangfei Gao 15 Sep '22

15 Sep '22

Introduce a new crypto PMD for UADK, which relies on UADK library [1]. UADK is a framework for user applications to access hardware accelerators. UADK relies on IOMMU SVA (Shared Virtual Address) feature, which share the same page table between IOMMU and MMU. Thereby user application can directly use virtual address for device dma, which enhances the performance as well as easy usability. Currently supported platforms: HiSilicon kunpeng920 & kunpeng930. This patch adds a basic framework.

I think given the current progression it is OK for this series to leave the SMMU driver with a bit of a different view of how the API should work. The main target here is the in-kernel drivers and they won't trigger these cases. As we extend things into userspace PASID support we may want to block SMMU PASID support through iommfd/vfio until it is updated. I've been thinking on and off about this - we likely need to have a conformance test suite as part of iommufd that is specifically for checking that the iommu driver meets the API. So it would do things like exercise scenario (a), attaching domains to all sorts of combinations, and so on. We know this from other driver subsystems that drivers can implement the uAPI incorrectly and it causes a lot of pain for userspace. Jason

UADK is a framework for user application to access hardware accelerator . https://github.com/Linaro/uadk/blob/master/docs/wd_design.md UADK relies on SVA (Shared Virtual Address) that needs to be supported by IOMMU. As a result, user application can directly use virtual address for dma, since iommu and mmu share the same virtual address by coping the same page table, which enhance the performance as well as easy usability. UADK provide algorithm libraries and api for application to use. The library will find the real hardware in the platform. We also provide openssl engine for uadk, https://github.com/Linaro/uadk_engine For alignment, we planned to provide uadk dpdk pmd as well, with the name as UADK. What do you think. Thanks.
