I double checked it - yes: before pci_map_rom: [drm] radeon_read_bios: pci_resource_start(ROM)=000001FF10020000 radeon 0000:02:02.0: BAR 6: assigned [mem 0x1ff00000000-0x1ff0001ffff] after pci_map_rom: [drm] radeon_read_bios, bios=000001ff00000000, pci_resource_start(ROM)=000001FF00000000, size=46592 [drm] radeon_read_bios: found ROM signature at 000001ff00000000 [drm] radeon_read_bios: bios=000001ff00000000, size=46592 -- Meelis Roos (mroos@xxxxxxxx) _______________________________________________ dri-devel mailing list dri-devel@xxxxxxxxxxxxxxxxxxxxx http://lists.freedesktop.org/mailman/listinfo/dri-devel
