Threading is handled by Mesa infrastructure (see the glthread.[ch] files there) - the driver itself it's not aware of the multiple threads, just multiple GL contexts. But since software rendering works OK it must be something more subtle. > And how > could I go on debugging this (knowing that I have also access to a laptop > with a Radeon Mobility chip but which has a rather old DRI version installed > on it - the one shipped with Mandrake 9) ? I don't know which version Mondrake 9 ships, but you really should get yourself a recent version to avoid debugging problems which may already been solved. There are driver snapshots for XFree86 4.3.0 from http://dri.sf.net/snapshots , but if you plan to do some serious debugging it may be easier to compile from CVS (see the web site for more info). You can use the RADEON_DEBUG env var with some values to generate more debugging. See radeon_context.c for more info. José Fonseca PS: The DRI source tree (spite being a cut-down version of the XFree86 source tree) is stil huge. Check the Developer FAQ on http://dri.sf.net/doc/faq for pointers to where the things are. ------------------------------------------------------- This SF.Net email is sponsored by: INetU Attention Web Developers & Consultants: Become An INetU Hosting Partner.
