If you say they were tested on real Power Architecture boards with PCIE videocards thus it is reassuring... and i'm happy that you understand my previus assertion wasn't affected by malevolence or sarcasm. Indeed i'm also a bit troubled 'n frustrated thinking that next release of mesa 'll do extend use of llvm (that doesn't work properly on linuxppc and totally untested on linuxppc64) Btw, to sum up the list of Power Architecture machines with PCIE that aim to be a desktop/workstation: Apple iMac G5 (iSight), Apple PowerMac Quad G5, YDL Powerstation 2x970MP and Acube Sam460ex . And the last two, on present evidence (my attempts), aren't able to boot up if bootkernel has kms enabled. Furthermore the first tree ones can fallback to the legacy OpenFirmware framebuffer and safely get a console. > It looks like there's a problem with accessing the PCIe device memory, > and at this point it's not even 100% clear that this is due to a problem > in the driver, as opposed to e.g. in the platform code. > it could be the right problem and i've CC BenH that has a better global perspective. all the best, --nico -- acrux <acrux@xxxxxxxxxxx> _______________________________________________ dri-devel mailing list dri-devel@xxxxxxxxxxxxxxxxxxxxx http://lists.freedesktop.org/mailman/listinfo/dri-devel
