[chop cc list] s390 mdev maintainers, Can I ask your help to test this with the two S390 mdev drivers? Now that gvt is passing and we've covered alot of the QA ground it is a good time to run it. Take the branch from here: https://git.kernel.org/pub/scm/linux/kernel/git/jgg/iommufd.git/log/?h=for-… And build the kernel with CONFIG_VFIO_CONTAINER=n CONFIG_IOMMUFD=y CONFIG_IOMMUFD_VFIO_CONTAINER=y And your existing stuff should work with iommufd providing the iommu support to vfio. There will be a dmesg confirming this. Let me know if there are any problems! If I recall there was some desire from the S390 platform team to start building on iommufd to create some vIOMMU acceleration for S390 guests, this is a necessary first step. Thanks, Jason

[PATCH v6 0/5] add dynamic driver loading function
by Longfang Liu 27 Dec '22

27 Dec '22

Update the current driver adaptation and usage method, from fixed use of Hisilicon device driver to automatic registration of the driver according to the algorithm. When the algorithm API layer uses the driver, it is no longer bound to the fixed device driver, but dynamically obtained and stored according to the algorithm query to use. Update the driver and API layer of the zip and sec module, keep the function of the init interface unchanged, update the implementation of the init2 interface and match the dynamic loading function. Changes v5 -> v6: - Rebase based on the patch of the zlib interface. Changes v4 -> v5: - Enhance the inclusiveness of the init2 interface. Changes v3 -> v4: - Remove the template instance code of cipher. - Split the scheduler code into a separate patch. Changes v2 -> v3: - Add dynamic library file search function - Fix some memory handling issues Changes v1 -> v2: - Fixed the compatibility method with the previous library file loading Longfang Liu (5): uadk: Add driver dynamic loading function uadk: update scheduler for dynamic loading uadk: improve the dynamic loading public framework uadk: added ability to query supported algorithms uadk/zip: Adapt the zip module to the dynamic loading framework Makefile.am | 4 +- drv/hisi_comp.c | 59 +++- include/drv/wd_comp_drv.h | 27 -- include/wd.h | 12 + include/wd_alg.h | 95 +++++++ include/wd_alg_common.h | 11 + include/wd_sched.h | 6 +- include/wd_util.h | 63 ++++- libwd.map | 8 + wd.c | 56 +++- wd_alg.c | 265 ++++++++++++++++++ wd_comp.c | 243 +++++++++-------- wd_sched.c | 105 +++++++- wd_util.c | 549 +++++++++++++++++++++++++++++++++++++- 14 files changed, 1337 insertions(+), 166 deletions(-) create mode 100644 include/wd_alg.h create mode 100644 wd_alg.c -- 2.33.0
