Wandboard Quad experience (good!)

Wandboard Quad experience (good!)

[Chris Tapp]

Thanks to help from Otavio and others, I now have an image building for the Wandboard Quad.

I've built a custom OpenGLES application running under EGL (which I normally run on a Cedar Trail platform) and it's mostly running as expected - just need to work out why my gstreamer pipeline isn't working.

The only bit that I had to work round was broadcom-nvram-config, which resulted in:

NOTE: Resolving any missing task queue dependencies
ERROR: Nothing RPROVIDES 'linux-firmware-INVALID' (but /media/SSD-RAID/meta-fsl-arm-extra-git/recipes-bsp/broadcom-nvram-config/broadcom-nvram-config.bb RDEPENDS on or otherwise requires it)
NOTE: Runtime target 'linux-firmware-INVALID' is unbuildable, removing...

I got round this by commenting out:

MACHINE_EXTRA_RRECOMMENDS += " broadcom-nvram-config"

in the machine file.

I fixed this and pused this for master-next; please confirm it works :-)

Hi Chris,

First off - thanks for trying out the kernel.  Let me know if you see
anything that needs to be fixed.  Patches are welcome, of course.

I chatted with Otavio about this issue because I'm working on getting Quad
up and running tonight.  He already has a patch to submit.  If you're
interested in trying this tonight, all you need to do is rename:

meta-fsl-arm-extra/recipes-bsp/broadcom-nvram-config/files/wandboard-dual

to

meta-fsl-arm-extra/recipes-bsp/broadcom-nvram-config/files/wandboard
(without the '-dual')

When we did this in the beginning, all we had with Wifi on it was the
Dual.  Now we have Quad, so we need to use a common directory.

John

Thanks, that's done the trick.

Kernel looks good so far - I just need to enable CONFIG_HID_APPLE so my keyboard works ;-)

Does that mean anything? I think this may be related to the gstreamer problems I've been having, but...

Re: Wandboard Quad experience (good!)

[John Weber]

Chris,

This looks like it is coming from the Vivante GPU driver in:
drivers/mxc/gpu-viv/hal/kernel/gc_hal_kernel.c, line 1315.

How would I replicate this problem?

I did make one commit to this driver to init some uninitialized variables. 
These were throwing some errors during kernel compile.  Other than that, this 
driver is untouched by me.

Good question! Simply running (with GST_DEBUG="*:2")

gst-launch playbin2 uri=http://media.w3.org/2010/05/sintel/trailer.webm video-sink="queue2 ! mfw_v4lsink"

sometimes gives this:

Re: Wandboard Quad experience (good!)

[John Weber]

Hi Chris,

Thanks.  You've probably noticed, but this is a different error from the first 
one you sent.  The first one was in the Vivante driver.

This one seems related to a memory limitation and perhaps related to the 
CONFIG_SWAP being on by default in the kernel build.  Since there is no swap 
partition, having CONFIG_SWAP seems a little useless.  Oddly enough, all of the 
default i.MX6 defconfigs set CONFIG_SWAP.  I'm seeing if we can remove that option.

John

Yes, I had spotted it was different...

Since there is no swap partition, having CONFIG_SWAP seems a little useless.  Oddly enough, all of the default i.MX6 defconfigs set CONFIG_SWAP.  I'm seeing if we can remove that option.

but I had no idea it was related to swap ;-) I'll disable locally and see if that makes a difference. I can't see why swap should be getting used as the app never uses anywhere near the 2GB the board has, but I've see linux hit swap when there still seems to be plenty of physical memory about, so this may be expected.

It is just possible that this may be related to the other issue, as I can imagine a gstreamer-heavy app does a lot of memory allocation/deallocation...

Re: Wandboard Quad experience (good!)

[Chris Tapp]

Hi John,

This (2nd crash) still happens when CONFIG_SWAP is not set, but it's just possible that the Vivante one has gone! I've had a board running my app. for over 6 hours hours and the problem hasn't shown yet. I'll keep it running...

However, I now see lots of:

[ 1481.696860] Not power off before vpu open!

Any idea what these are about?

I've also noticed that the Wandboard is very sensitive to power quality. The specs say a 5v, 2A PSU is suitable - but it's not if it's got a very fast current limit :-) I get reboots (uboot reports 'POR' reset cause) if I use a lab PSU set to 2A.

Re: Wandboard Quad experience (good!)

[John Weber]

Hi Chris,

You might want to consider emailing the wandboard-dev mailing list for Wandboard 
kernel questions.

wandboard-dev@lists.wandboard.org

You'll need to sign up of course:
http://wandboard.org/cgi-bin/mailman/listinfo/wandboard-dev

Or the main user group at
wandboard@googlegroups.com

I haven't seen that message in using the video encoder functionality of the VPU 
from Gstreamer.  Just greping the source, that message comes from the vpu driver 
(as expected).  During vpu_open(), it seems to be enabling the clock to the VPU, 
then checking to see if the clock is enabled by checking a program counter of 
what is I'm guessing the integrated bitstream processor in the VPU.  If that is 
greater than 0x0, then it pops that debug message.  Then it disables the vpu 
clock, then moves on.

Since there is no swap partition, having CONFIG_SWAP seems a little useless.  Oddly enough, all of the default i.MX6 defconfigs set CONFIG_SWAP.  I'm seeing if we can remove that option.

Re: Wandboard Quad experience (good!)

[Thomas Senyk]

I do get the 
[ 1685.143891] Physical memory allocation error!

errors as well! (same back-trace so I will not repeat)

I'm using a nitrogen6x right now.
I've already set CONFIG_SWAP=n, which didn't help for me.

This morning I used to somehow(! read a bit below why it's not a solution for 
me) work around this issue with this patch:
http://pastebin.com/hRgpitvP

inspired by a patch from:
https://community.freescale.com/message/316472#316472


However this morning I switched to master for all my layers (meta-fsl-arm-
extra is master-next), now if I apply this patch I get kernel-panic at start-
up:
< I don't have the log/back-trace right now, if requested I can provide it >



Anyway .. I'm not sure it's the right solution!... because although I got rid 
of the kernel errors I had a different problem then:

Somehow the kernel and/or the application started to misbehave at some point.
The framebuffer went black (and even /dev/urandom couldn't do anything about 
it), and if I tried to kill the application (SIGTERM or SIGKILL) it became a 
zombie and consumed ~25-30% CPU continuously. Only a reboot helped.

Sound like 'it ended up in a kernel endless loop' .. doesn't it?

some clearification bout 'at some point':
I'm playing the same file (big bug bunny 1080p) over and over again and after 
the 3-5th loop the screen gets dark and the application becomes a zombie.

Just tested with the new kernel, I only got memory-error twice and could just 
continue playing with 'trying again'




One addition from wandsolo:
I just finished my wandsolo build and this error happens as soon as I try to 
play anything with 1080p. It's working with 720p.

Any advice?
Maybe it's related .. maybe it's just '512mb isn't enough  for 1080p' .. but 
that would be surprising, wouldn't it?
