This patch set introduces an initial set of KUnit test suites for the core components of the FPGA subsystem. Tests can be run using: [user@localhost linux]$ ./tools/testing/kunit/kunit.py run --kunitconfig=drivers/fpga/tests v10: - Improved code style and fixed comment typos for FPGA Manager ops v9: - Improved and commented test ops for the FPGA Manager test suite - Fixed minor capitalization discrepancies v8: - Using memset to set header and payload of the test image - Using sg_miter_* functions to check the image in the write_sg op - Includes sorted in alphabetical order - Add commas for fpga_bridge_ops - Improved Makefile v7: - Dropped RFC prefix - Add comments to explain fakes and helper functions - Changed the implementation of the Bridge used in the Region suite v6: - Restructured the code into self-contained test modules - Added tests for the basic behaviors of the components - Improved programming tests for the FPGA Manager - Fixed code/comments mismatch in the list of Bridges test case v5: - Removed most of the exported functions using shared buffers for stats - Moved all KUnit expectations/assertions to the main test module - Removed standalone use case to simplify the code - Removed instances counters from fake components (using device.id instead) - Set header size in the .parse_header op - Improved bridge get_put_list test case v4: - Fix build error v3: - Calling fpga_bridges_put() between reconfigurations - Functions for registering fake modules allocate and return context structs v2: - Restructured code into multiple suites to test components in isolation - Reduced code duplication using init and exit methods - Using a get_bridges() method to build the list of bridges just before programming - Regions and Bridges are organized topologically - Changed bitstream/bit to images - Allocate images dynamically - Renamed fpga-tests to fpga-test - Simplified Kconfig - Add license info to the fpga-test module Marco Pagani (4): fpga: add an initial KUnit suite for the FPGA Manager fpga: add an initial KUnit suite for the FPGA Bridge fpga: add an initial KUnit suite for the FPGA Region fpga: add configuration for the FPGA KUnit test suites. drivers/fpga/Kconfig | 2 + drivers/fpga/Makefile | 3 + drivers/fpga/tests/.kunitconfig | 5 + drivers/fpga/tests/Kconfig | 11 + drivers/fpga/tests/Makefile | 6 + drivers/fpga/tests/fpga-bridge-test.c | 175 ++++++++++++++ drivers/fpga/tests/fpga-mgr-test.c | 327 ++++++++++++++++++++++++++ drivers/fpga/tests/fpga-region-test.c | 211 +++++++++++++++++ 8 files changed, 740 insertions(+) create mode 100644 drivers/fpga/tests/.kunitconfig create mode 100644 drivers/fpga/tests/Kconfig create mode 100644 drivers/fpga/tests/Makefile create mode 100644 drivers/fpga/tests/fpga-bridge-test.c create mode 100644 drivers/fpga/tests/fpga-mgr-test.c create mode 100644 drivers/fpga/tests/fpga-region-test.c base-commit: fdf0eaf11452d72945af31804e2a1048ee1b574c -- 2.41.0
