OpenCPN on Raspberry PI2

[verkerkbr]

You can also do:

sudo apt dist-upgrade

This gives a distribution update with Wayland.

OpenGL in OpenCPN can be switched to on.

This gives even more fast charts movements in OpenCPN

Hi,

I try to test the OpenGL speed on RPI3 but I can reach only about 100FPS.
And I need to perform a 'sudo apt dist-upgrade'
to move from 20FPS to 100FPS see my notes:

Thanks! I just updated to Wayland. I am getting glxgears 100-150fps, depending on what other apps are running, so this seems to be a SW renderer, not a HW accelerated opengl? Can someone with more knowledge confirm?

Still, opencpn seems to work well with opengl=on.

Dirk,

open logfile info:

OpenGL rendering string Gallium 0.4 on llvmpipe (LLVM 3.9 128 bits)
OpenGl version reported 3.0 Mesa 13.0.0

and more OpenGL settings.

Not yet tried the combination with the VC4 driver.

With the OpenGL setting to on it works very well.

VC4 worked also very well, but gave problems with zooming out. Then the image was scattered.

Anyway this without the VC4 driver, is a big improvement.

Regards,

Bram

Just tried the OpenGL VC4 driver. If you click on the setting in raspi-config, additional software is installed.

It works in OpenCPN but locks up. Glxgears reported errors with libGL and Mesa and also locks up.

Hi,

after doing a apt-get update and apt-get dist-upgrade I can run glxgears with round about 90 to 105 fps. OC with my rastercharts works faster with OpenGL = on then before the upgrade and with OpenGL=off. No Limits when zooming or panning it just works.

Now I tried the vc4 driver but I made a fault and the pi crashes when booting.

Now I´m just putting the backup to the sd-card and then starting again.

Regards

Andreas

[Andreas29]

Hi,

after playing around with the pi2 and the grafic-drivers I can say this:

After doing a apt-get update and apt-get dist-upgrade (and reboot) it´s possible to get 70 to 105 fps with glxgears without enabling the experimental pi grafic driver. Glxinfo said that there is hw-grafic acceleration.
When switching OpenGL on in OC it works without any crashes. Zooming and panning without probs (tested with my rastercharts up to 50mb). Trying different Settings for the video ram, 64 or 128 mb seems to be the best.
Using OpenGL in OC makes it working much smoothier.

When enabling the experimental grafic driver (vc4) then it´s possible to get much more fps in OC but it still crashes when zooming out to much.

Kernel version from my pi ist 4.4.37.

Regards

Andreas

Hi,

I found out why I have had only up to 105FPS while somebody can have up to 140FPS on RPi after (update, upgrade, dist-upgrade, rpi-update).
And the answer is so simply as changing power supply to bigger one.
Now I moved from ~100FPS to ~170FPS with only changed power supply

pi@openplotter:~ $ sudo glxgears
648 frames in 5.0 seconds = 129.563 FPS
813 frames in 5.0 seconds = 162.495 FPS
860 frames in 5.0 seconds = 171.983 FPS

798 frames in 5.0 seconds = 159.397 FPS
837 frames in 5.0 seconds = 167.369 FPS
792 frames in 5.0 seconds = 158.212 FPS
789 frames in 5.0 seconds = 157.790 FPS
874 frames in 5.0 seconds = 174.615 FPS

Bram,

I can confirm this, also have faults when using the VC4-driver.

Without using the VC-4 Driver all is fine.
CPU load when using OpenGL=on in OC and my 50mb rastercharts is 50 to 60 %.

But panning is much usable then before, yes.

Regards

Andreas

[verkerkbr]

Allo Andreas,

now with Wayland and the latest kernel upgrade to 4.4.38 and the latest upgrades, VC4 driver seems to work with OpenCPN.

Still not perfect, but you can give it a try.

Switching off is easy to do.

Have memory setting on 80.

Regards,


Bram

I have just installed OpenCPN on RPI 3B. Everything mostly works fine until I click the 'Options' button, then OpenCPN crashes.

I have both ENC & RNC charts installed, and they both display.

Any ideas?

magick,

try building with cmake -DCMAKE_BUILD_TYPE=Debug and get a backtrace

Hi Magict,

Have you enlarge the Partition on the SD Card ? It is in the Raspberry menu.

This is always the first thing you must do.

And take a fast micro SD with reading speed of 80. 16 or 32 GB.

Bram

[magick]

Installed the latest version.

4.2.0 Build 2016-02-03.

Works fine now.

Thanks for your suggestions.

I have tried the new raspbian with vc4 driver....

I had to build opencpn from source. Maybe we should provide binaries for raspberry so the usual method with apt-get can work. Otherwise you need much more disk space to install all the development requirements.

It appears that opengl doesn't support texture compression. I think maybe they fixed this in the git version of the driver to support ETC1 in biggl (which is non-standard) but I will try again to see if I can use gles with the vc4 driver and opencpn.


I have a lot of pending pull requests which improve performance considerably as well, especially in certain cases.

Now I reinstall to 32gb as 4gb isn't enough to do development.
