[PATCH v3 0/6] uadk - add wd_comp_init2
by Yang Shen 29 Sep '22

29 Sep '22

The current uadk initialization process is: 1.Call wd_request_ctx() to request ctxs from devices. 2.Call wd_sched_rr_alloc() to create a sched(or some other scheduler alloc function if exits). 3.Initialize the sched. 4.Call wd_<alg>_init() with ctx_config and sched. Logic is reasonable. But in practice, the step of `wd_ request_ Ctx() ` and `wd_ sched_ rr_alloc() ` are very tedious. This makes it difficult for users to use the interface. One of the main reasons for this is that uadk has made a lot of configurations in the scheduler in order to provide users with better performance. Based on this consideration, the current uadk requires the user to arrange the division of hardware resources according to the device topology during initialization. Therefore, as a high-level interface, this scheme can provide customized scheme configuration for users with deep needs. All algorithm initialization interfaces have the same input parameters and behavioral logic. The pre-processing of the wd_<alg>_init is actually the configuration of `struct wd_ctx_config` and `struct wd_sched`. Therefore, the next thing to be done is to use limited and easy-to-use input parameters to describe users' requirements on the two input parameters, ensuring that the functions of the new interface init2 are the same as those of init. For ease of description, v1 is used to refer to the existing interface, and v2 is used to refer to the layer of encapsulation. At present, at least 4 parameters are required to meet the user configuration requirements with the V1 interface function remains unchanged. @device_list: The available uacce device list. Users can get it by wd_get_accel_list(). @numa_bitmask: The bitmask provided by libnuma. Users can use this parameter to control requesting ctxs devices in the bind NUMA scenario. @ctx_nums: The requested ctx number for each numa node. Due to users may have different requirements for different types of ctx numbers, needs a two-dimensional array as input. @sched_type: Scheduling type the user wants to use. What's more, some users want uadk to provide the default value about input parameters for some performance insensitive scenes. C code has no way to. Changelog: v2->v3: - update the wd_comp_init2 parameters. v1->v2: - Update the desdescription about wd_<alg>_init in wd_design.md.

[PATCH v2 0/5] crypto/uadk: introduce uadk crypto driver
by Zhangfei Gao 29 Sep '22

29 Sep '22

Introduce a new crypto PMD for hardware accelerators based on UADK [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.

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
