Mark, can you still take these changes first? Since this failed
test that Caleb reported here is already existing on the top of
the mainline tree, I would like to treat this mail as a separate
bug report and fix it with a separate patch.

Besides, this series of changes don't change any function flow.

Thank you

Sorry! I should have created a separate thread for this subject. My
comments have *nothing* to do with this patch set, except they are
about the same source files.

--- To Caleb ---

I'm re-setting up my loopback test to try to verify these most recent changes.
I really appreciate your verification and help.
Of course! I have this wandboard permanently set up for this
verification test, so that I can easily repeat whenever I touch our
kernel.

It's a dead-simple hardware mod just to connect TX to RX.

Those last 4 lines are the channel slips -- the least significant
nibble should be the channel number: i.e. should go 0, 1, 2, 3, 4, 5,
6, 7.

Ugh, so it's basically quite broken again -- before these patches.
I remember Arnaud reviewed one of my changes back to September.
So I suppose the test should be fine at that time -- so a change
being merged recently might have impacted the test result.

It's certainly possible that I'm doing something wrong again -- it
wouldn't be the first time :-)

Hi All,

Sorry but I will be busy until mid January, I could help testing and fixing broken multi channel after.
Anyway, I don't see specific issues with Nicolin patches.
We can take time to fix what was broken before this patch set... after.

Arnaud


I guess I need to go backwards in time and see what rev re-broke it.
I don't really have time to dig too deep on this again.

I'd be happy to provide the hardware to anybody that can diagnose and
debug this more quickly than I can. I'm very inefficient at kernel
drivers I think. My day job is acoustical and electrical
engineering.

Here's what the hardware looks like for anybody that's interested.
Just a single wire loopback on the wandboard header.
I would definitely like to take the hardware to debug it as long
as you are willing to provide me. Can you send me a private mail
to discuss about it?
Absolutely.
