Hi, This patchset adds support for selftests in the devlink framework. It adds a callback .selftests_check and .selftests_run in devlink_ops. User can add test(s) suite which is subsequently passed to the driver and driver can opt for running particular tests based on its capabilities.
Patchset adds a flash based test for the bnxt_en driver.
Suggested commands at user level would be as below:
changes from: v4->v5: Addressed the changes requested by jiri@nvidia.com in patch v4.
v3->v4: Addressed the changes requested by kuba@kernel.org in patch v3.
v2->v3: 1) After discussions with jiri@nvidia.com, passing a testmask from user to kernel is removed and a flag based arguments are adopted. This way we can have more than 32/64 selftests defined in the kernel. Below is the format from user to kernel and vice-versa.
Kernel to user for show command . Users can know what all tests are supported by the driver. A return from kernel to user if driver supports TEST1, TEST4, and TEST7. ______ |NEST | |_____ |TEST1|TEST4|TEST7|...
User to kernel to execute test: If user wants to execute test4, test8, test1... ______ |NEST | |_____ |TEST4|TEST8|TEST1|...
After executing the tests kernel return to user. |NEST | |_____ | NEST| |NEST| |NEST| TEST4,RES4 TEST8,RES8 TEST1, RES1 2) Added dumpit in devlink for list/show command.
v1->v2: Addressed the changes requested by kuba@kernel.org in patch v1. Fixed the style issues.
Thanks, Vikas
