Display HP S410u possible workling with RaspberryPi

Mahdi2016 · 11-11-2016, 10:42 AM

Hi Michal,

i've built the evdi module and it works fine.

here is the output from lsmod:

Code:

#lsmod | grep evdi
evdi                   36280  0
drm_kms_helper        101028  3 vc4,evdi
drm                   262564  5 vc4,evdi,drm_kms_helper
syscopyarea             2945  2 evdi,drm_kms_helper
sysfillrect             3443  2 evdi,drm_kms_helper
sysimgblt               2069  2 evdi,drm_kms_helper

After that I started building the evdipp package.

After 'make install' the build breaks up with the following message:

Code:

Hi,

You need a C++14 compliant compiler. For the reasons I can't fully understand you sometimes must pass CXX flags manually, as cmake setting that I think should work doesn't

Have a look at https://github.com/mlukaszek/evdipp/...er/.travis.yml - this is the configuration for Travis CI. I was forced to run cmake with -DCMAKE_CXX_FLAGS="-std=c++14" as you'll see.

Cheers,
Michal

Hi Michal,

i've built the evdipp package without errors.

After reboot and plug in the HP s140u Monitor and type "sudo monitorsim EDIDv1_1600x900"
a new clear window opened and after 10 seconds the window closed automatically. The output of the terminal window is at follows:

Code:

pi@raspberrypi:~ $ sudo monitorsim EDIDv1_1600x900
[libevdi] ioctl: drop_master error=-1
[libevdi] ioctl: drop_master error=-1
[libevdi] ioctl: drop_master error=-1
MESA-LOADER: failed to retrieve device information
MESA-LOADER: failed to retrieve device information
MESA-LOADER: failed to retrieve device information

Please i need some help and i havent any ideas anymore.

Hmm. Try with something simpler first, e.g. the "example" program that you also built.
This won't show any pixels, but will possibly print more to the console, especially if you
enable debug printout (you need to define DEBUG for the build).

What's closing the app? Is it crashing? If yes, then running it in gdb might give some extra clues.

Cheers,
Michal

Mahdi2016 · 11-15-2016, 10:12 AM

Hi Michal,

i've built the evdipp package with debug symbols. The output of the terminal window is at follows:

Code:

(gdb) run
Starting program: /bin/monitorsim edid.dat --enable-debug
[Thread debugging using libthread_db enabled]
Using host libthread_db library "/lib/arm-linux-gnueabihf/libthread_db.so.1".

The output from 'example' command of the terminal window is at follows:

Code:

(gdb)

The "edid.dat" is generated with "tvservice -d edid.dat" (for the pluged in HDMI-Monitor).

I hope that helps.

Best regards
Michael

mlukaszek · 11-16-2016, 08:14 AM

What happens if you use a full path to edid file. The message indicates that the program had problems with opening/reading the file that you gave as an argument?

Cheers,
Michal

Mahdi2016 · 11-22-2016, 11:40 AM

Hi Michal,

i'm back from vacation.

Here is the output from 'example' command of the terminal window is at follows:

Code:

(gdb) run

[Inferior 1 (process 962) exited with code 01]

And the output from 'monitorsim' command of the terminal window is at follows:

Code:

(gdb) run
Starting program: /bin/monitorsim /home/pi/EDIDv1_1280x900 --enable-debug

I hope that helps.

Hi Michal,

I have tested as native desktop and with ssh.

Here is the output from 'example' command of the terminal window is at follows:

Code:

sudo /bin/example /home/pi/EDIDv1_1440x900
[libevdi] ioctl: drop_master error=-1
Attempting to use device /dev/dri/card1...
[libevdi] ioctl: drop_master error=-1
Press Enter or Ctrl+C to quit...

In the same time the other window is at follows:

Code:

And here is the output from 'monitorsim' command of the terminal window is at follows:

He're how it looks on my Pi - just had a moment to try a few things out. Note this is WITHOUT evdi loaded yet.

Code:

$ uname -a
Linux ubuntupi 4.4.35-v7+ #931 SMP Sat Nov 26 13:05:09 GMT 2016 armv7l armv7l armv7l GNU/Linux

Code:

$ lsmod | grep drm
drm_kms_helper        101028  2 vc4
drm_mipi_dsi            8702  1 vc4
drm                   262564  4 vc4,drm_kms_helper
syscopyarea             2945  1 drm_kms_helper
sysfillrect             3443  1 drm_kms_helper
sysimgblt               2069  1 drm_kms_helper
fb_sys_fops             1309  1 drm_kms_helper

And the most important difference - Sink Offload capability is present:

Code:

$ xrandr --listproviders 
Providers: number : 1
Provider 0: id: 0x43 cap: 0x9, Source Output, Sink Offload crtcs: 3 outputs: 1 associated providers: 0 name:modesetting

I used rpi-update and rpi-source to get the freshest kernel and its sources. What happens if you try the same?

Cheers,
Michal

Hi Michal,

I use Debian Jessi (raspbian) on my RaspberryPi 2.
The system is up-to-date.

Here is the output from 'uname -a' command of the terminal window is at follows:

Code:

Linux raspberrypi 4.4.34-v7+ #930 SMP Wed Nov 23 15:20:41 GMT 2016 armv7l GNU/Linux

Here is the output from 'lsmod | grep drm' command of the terminal window is at follows:

Here is the output from 'xrandr --listproviders ' command of the terminal window is at follows:

Code:

What kind of OS do you use on your Raspi?

Best regards
Michael
