chromium-browser dies when trying to run a webgl application with GLES on ARM

[Ricardo Salveti]

Binary package hint: chromium-browser

With a Pandaboard, running with the PVR SGX drivers installed from ti-omap/omap-trunk PPA, chromium browser dies when trying to run a webgl application.

To use the GLES support you need to start up chromium giving the "--use-gl=egl", then go to http://khronos.org/webgl/wiki/Demo_Repository and try to run any webgl demo, and chromium will die.

The only messages you get from chromium is about the lack of PCI support:

+ exec /usr/lib/chromium-browser/chromium-browser --use-gl=egl

pcilib: Cannot open /proc/bus/pci
pcilib: Cannot find any working access method.
pcilib: Cannot open /proc/bus/pci
pcilib: Cannot find any working access method.

This is because the method CollectGraphicsInfo (chrome/gpu/gpu_info_collector_linux.cc) expects the user to be running on a machine with proper PCI support, to get more info about the board. But even with the wrong code, I don't know this should affect in a way that would freeze chromium.

And it's correctly loading libEGL and libGLESv2.

whether you have SGX or mesa doesn't make a difference?

Natty have reached EOL since a while; and many changes/upgraded versions have been made; so it needs to be confirmed, if necessary, with a more recent version.Closing it by now.
