This series is tested with IMX219 camera sensor.
Which tree did you base this on? The media_tree master? Or the
mainline kernel?
These patches are with linux-next base at the time I sent them out
which
are on 20200616
I now have the imx219 detected, but if I try to stream I get this:
$ v4l2-ctl --stream-mmap
<[ 512.840944] video4linux video0: MW_ACK_DONE syncpt timeout: -11

<VIDIOC_DQBUF: failed: Input/output error
[ 513.180770] video4linux video0: MW_ACK_DONE syncpt timeout: -11
And then everything hangs and I need to reset.
I'm testing with the media_tree master with your patches on top.

Are you using same device tree as I sent offline? It uses CSI A for
IMX219.
Does you setup also uses CSI-A as x2 for IMX219?
I tested them on Jetson Nano + IMX219 rasp PI module and also on Jetson
TX1 + IMX274.
I did not see any issue and am able to capture from both.
Will try again on my side with today's latest linux-next and update
result.
Please use the media_tree master, that's what I use as well.
I did some more testing and there is something weird going on.
I have a Leopard Imaging camera expansion board (LI-JTX1-MIPI-ADPT) with
three camera connectors. See here for the datasheet:
https://www.leopardimaging.com/uploads/LI-TX1-KIT-IMX274M12-T_datasheet.pdf
The first connector (with an IMX274) causes this error:
$ v4l2-ctl -d1 --stream-mmap
[ 599.265885] video4linux video1: MW_ACK_DONE syncpt timeout: -11
[ 599.473883] video4linux video1: MW_ACK_DONE syncpt timeout: -11
[ 599.681904] video4linux video1: frame start syncpt timeout: -11
[ 599.681909] video4linux video1: MW_ACK_DONE syncpt timeout: -11
<VIDIOC_DQBUF: failed: Input/output error
[ 599.897884] video4linux video1: MW_ACK_DONE syncpt timeout: -11
Similar to the test above where I had an IMX219 connected. Except it
didn't
hang with the IMX274 (I'm beginning to suspect a locking issue in the
imx219
driver that is causing the hang, I'll look at that tomorrow).
If I connect the IMX219 to the middle camera connector, then it works
fine.
I think I tested this with the IMX274 as well, but I'm not 100%
certain, also
something to double check tomorrow.
If I connect the IMX219 or IMX274 to the third camera connector, then
I get this:
Would like to know CSI port mapping to connectors as mipi calibrate
pads cells need to be updated in device tree based on CSI port in use.
Will see if I can find that from DS link you sent above.

Something is producing EMEM address decode errors. But it is streaming.
above memory controller errors may be due to access faults and not
sure why these show up on your setup. I never have these with my testing.
Also I am using CMA alloc of 256MB and not sure if low CMA alloc size
is causing this. Can you try with CMA alloc size of 256MB?
If I enable the TPG then everything is fine.
So I have currently three different behaviors for three camera
connectors.
Do you have a datasheet for your Jetson TX1 camera board? It could be
useful
to compare the two.
Yeah we have and will send it offline.
Also based on connector mapping to corresponding CSI port,
mipi-calibrate pad cell value also need to be changed.
Below is for CSI-A
nvidia,mipi-calibrate = <&mipi 0x001>
Regards,
Hans
Connector-1 is CSI-AB where you had timeouts.
Connector-2 is CSI-CD and this works for you.
Connector-3 is CSI-EF and this works for streaming from above but
there's memory access fault errors (EMEM address decode errors)
These EMEM decode errors are not related to connector but its just they
showed up during connector-3 testing I believe. Can you also keep CMA
size to 256MB and try?
Not sure if CSI-AB issue with FS and MW_ACK sp timeouts are due to some
HW/setup issue. Streaming should work on CSI-AB ports as well just like
CSI-CD/EF with proper device tree change for port index and mipi
calibrate cells for corresponding ports.
On my setup that I tested IMX274 is on CSI-AB.
Will update my side test results with today's linux-next
