[PATCH v7 0/6] add dynamic driver loading function
by Longfang Liu 07 Jan '23

07 Jan '23

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 v6 -> v7: - Added dynamically loaded design documents. 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 (6): uadk: Add driver dynamic loading function uadk: update scheduler for dynamic loading uadk: improve the dynamic loading public framework uadk/doc: adding dynamically loaded design documents uadk: added ability to query supported algorithms uadk/zip: Adapt the zip module to the dynamic loading framework Makefile.am | 4 +- ...sion_and_modular_dynamic_loading_design.md | 432 ++++++++++++++ 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 +++++++++++++++++- 15 files changed, 1769 insertions(+), 166 deletions(-) create mode 100644 docs/UADK_framework_expansion_and_modular_dynamic_loading_design.md create mode 100644 include/wd_alg.h create mode 100644 wd_alg.c -- 2.33.0
