Subject: [PATCH net-next v4 0/3] add framework for selftests in devlink
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:
v3->v4:
Addressed the changes requested by kuba@...nel.org in patch v3.
v2->v3:
1)
After discussions with jiri@...dia.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@...nel.org in patch v1.
Fixed the style issues.
Thanks,
Vikas
