X on GL is going to eliminate all device access from X. Everything will be handled from the OpenGL layer. When everything is finished even the OpenGL layer won't do hardware access either, it will IOCTL the DRM driver to do it. In the final solution the only user of the VGA control should be the secondary card reset program. Where is the PCI segment base address stored in the PCI driver structures? I'm still having trouble with the fact that the PCI driver does not have a clear structure representing a PCI segment. Shouldn't there be a structure corresponding to a segment? >From what I understand right now the SN2 machine can not have two active VGA cards since it does not have two PCI segments. Without two segments there is no way to tell the legacy addresses apart. -- Jon Smirl jonsmirl@gmail.com - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
