I would urge you however to be careful when making changes to the SAREA to ensure that it does not contain any OS-specific elements. If/when I port the DRI to FreeBSD, I want to make it possible to run Linux DRI programs under FreeBSD's Linux emulator. This would involve running a Linux DRI program linked to a Linux version of e.g. gamma.so which was talking to the FreeBSD kernel DRI component and a FreeBSD native X server. This is actually a pretty reasonable setup as long as the SAREA has identical format on both Linux and FreeBSD. The arguments to DRI ioctls can be converted if necessary (I would prefer to avoid it but it is possible) but since the SAREA is a shared memory structure, it will not be possible to convert this in FreeBSD's Linux emulator. -- Doug Rabson Mail: [EMAIL PROTECTED] Nonlinear Systems Ltd.
