[U-Boot] Driver model test breakages

[Simon Glass]

Hi,

The following three commits causes breakages in the driver model tests:

4efad20a      sf: Update status reg check in spi_flash_cmd_wait_ready
45b47734     net/arp: account for ARP delay, avoid duplicate packets on timeout
9961a0b6    sandbox: add a sandbox timer and basic test

Can you please take a look? You can run them with ./test/dm/test-dm.sh

The last one looks a bit complicated - I suspect it will be harder to
fix. I am going to try to come up with some ideas...

Regards,
Simon

I didn't add a timer to test.dts. Please check if the dm timer fixed 
with this patch.

You can comment out the test declaration in test/dm/eth.c.

Jagan this is still broken - any ideas please?

This is still broken - Joe do you have any ideas? The release is coming soonish.

This seems to be fixed - thanks Thomas!

This was the first commit that caused the timeout to not get skipped,
however it would time out and proceed.

What caused the test to start hanging indefinitely is this commit:

159fb22 (sandbox: add a sandbox timer and basic test)

I'm still looking into why.

That's actually the incorrect hash - should be 9961a0b

It seems to be the same repair needed for the timer test. Simply need
to add the timer to test.dts.

OK, it could be fixed in u-boot-dm/master - there was no timer enabled
in sandbox!

It appears that ac1d313 (net: eth: Check return value in various
places) breaks the eth_rotate test.

Looking into it. Bin, do you have any ideas?

I will look into this.

BTW: I applied the following two patches [1][2] to the tree based on
dm/master, and got a segmentation fault:

Test: dm_test_usb_keyb
./test/dm/test-dm.sh: line 14: 24902 Segmentation fault
./sandbox/u-boot -d ./sandbox/arch/sandbox/dts/test.dtb -c "ut dm"

Interesting. I haven't tested on top of dm/master, but I tested it
based on origin/master and the issue is resolved.

Which issue is resolved? I just tested on top of origin/master with

The segmentation fault happens after "Test: dm_test_usb_keyb". It
seems to be a new issue.

I am looking into _dm_test_eth_rotate1 failure, but I don't understand
the comments here.

/* If ethrotate is no, then we should fail on a bad MAC */
setenv("ethact", "eth at 10004000");
setenv("ethrotate", "no");
ut_asserteq(-EINVAL, net_loop(PING));
ut_asserteq_str("eth at 10004000", getenv("ethact"));

Does 'bad MAC' mean no MAC address? For eth at 10004000, it does have a
MAC address defined in the env variable in sandbox.h.

I also tested manually with the same test sequence from U-Boot shell,
it can pass. I am still looking into it.

=> setenv ethact eth at 10004000;setenv ethrotate no;ping 1.1.1.1
Using eth at 10004000 device
host 1.1.1.1 is alive
=> printenv ethact
ethact=eth at 10004000

Bin

I agree it's a new issue that was masked by the net_retry hang.

I think if you look at dm_test_eth_rotate(), the eth1addr is deleted
before the test. Later, ethaddr is deleted before the second part of
the test.

It's not as though it hangs or something, but it now fails to return
the error code that it used to before your patch.

Test: dm_test_eth_rotate
../test/dm/eth.c:160, _dm_test_eth_rotate1(): -EINVAL ==
net_loop(PING): Expected -22, got 0

It appears, not too surprisingly, that d77a7d8 (dm: test: usb:
sandbox: Add keyboard tests for sandbox) is the source of the seg
fault.

In looking for the seg fault in the usb kbd test, I found that the
udev ptr passed to usb uclass is garbage, so the usb_ops is null, so
we crash. Do you have a quick explanation for how this emulated USB is
supposed to work? I haven't looked at it before. I'll keep digging
until you can provide some insight.

Actually the controller passed in is OK and the driver ptr is OK, but
the ops ptr is NULL. Seems odd.

Jagan, do you have any thoughts on the SPI flash crash with
test/dm/test0dm,sh? It is still broken and the release is almost upon
us. This means that SPI flash is not working correct at present.

Sorry, that I couldn't find this mail as it moved some where.

And I never ran these dm tests before tried now - please see below.

Test: dm_test_rtc_set_get
Test: dm_test_spi_find
../test/dm/spi.c:63, dm_test_spi_find(): -ENOENT ==
spi_get_bus_and_cs(busnum, cs, speed, mode, "spi_flash_std", "name",
&bus, &slave): Expected -2, got -22
Test: dm_test_spi_flash
./test/dm/test-dm.sh: line 14: 14628 Segmentation fault      (core
dumped) ./sandbox/u-boot -d ./sandbox/arch/sandbox/dts/test.dtb -c "ut
dm"

these are the issues? from you mail how come these issues related to

4efad20a      sf: Update status reg check in spi_flash_cmd_wait_ready

Because this particular change is respective to spi_flash core and the
drivers/mtd/spi/sandbox is not using I suppose.

Please let me know your inputs.

thanks!

Please ignore the 'Segmentation fault' issue. Simon got it fixed in
other patches.

I believe Simon pinpointed this commit via 'git bisect'. You should be
able to use 'git bisect' to get the same result.

Please see u-boot-dm/master. There are also patches in this series
which I have not applied yet:

http://patchwork.ozlabs.org/patch/562195/

Also you can disable any tests you don't want by commenting out things
in the Makefile. Unfortunately you can't run the SPI tests by
themselves (with 'ut dm <testname>') unless you create the test file
manually.

Please let me know if you come up with a fix.

During debug I've noticed another strange issue:

Sometimes the sandbox's setenv() does not successfully set the
environment variable to the expected value. This occurs from time to
time, even with the same u-boot image. Do you have any idea about
this?

I may have been dazed that I looked the wrong message line. The issue
is complicated. My commit just exposed an existing issue that have
been in the dm eth codes from the beginning, that the eth_set_dev()
logic is not controlled by the env variable "ethrotate". If the
"ethact" is set to an eth device which cannot be probed (eg: no valid
ethaddr) and "ethrotate" is set to "no" (like in this test case), the
"ethact" will still point to the first probable eth device, in this
sandbox case, eth at 10002000.

I am still figuring out where to fix. Joe, you might want to have a look?
