[RFC PATCH v3 0/4] fpga: add initial KUnit tests for the subsystem

From: Marco Pagani
Date: Fri Apr 14 2023 - 12:37:36 EST


This patch set introduces initial KUnit test suites for the FPGA subsystem.

Tests can be run using:
[user@localhost linux]$ ./tools/testing/kunit/kunit.py run --kunitconfig=drivers/fpga/tests

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 fake FPGA manager
fpga: add fake FPGA bridge
fpga: add fake FPGA region
fpga: add initial KUnit test suites
