Hello again Liwei! Thanks for your patch it applied good :) With your patch I can run my ATI 5450 as primary GPU (I have no secondary at all) as basic VGA: Windows XP can start and show the desktop if it has no installed drivers. It is very big progress for me :) After I installed drivers it can't init the GPU. I think when you tries to install Win7 you got same - because it already have buildin drivers and tries to init extended display mode. My logs is: root@xen:/var/log/xen# tail -f /var/log/xen/qemu-dm-winxp.log (here domU started up) pt_iomem_map: e_phys=d0000000 maddr=d0000000 type=8 len=268435456 index=0 first_map=1 pt_bar_reg_read: first read BARs of gfx pt_bar_reg_read: first read BARs of gfx pt_iomem_map: e_phys=febc0000 maddr=febc0000 type=0 len=131072 index=2 first_map=1 pt_bar_reg_read: first read BARs of gfx pt_bar_reg_read: first read BARs of gfx pt_ioport_map: e_phys=e000 pio_base=e000 len=256 index=4 first_map=1 pt_iomem_map: e_phys=f1000000 maddr=febfc000 type=0 len=16384 index=0 first_map=1 platform_fixed_ioport: changed ro/rw state of ROM memory area. now is rw state. platform_fixed_ioport: changed ro/rw state of ROM memory area. now is ro state.
