The xf86-video-intel repo at git://git.freedesktop.org/git/xorg/driver/xf86-video-intel has a tool called "intel_reg_dumper" in src/reg_dumper that you can use to capture the dumps. If you're having trouble building it just check out an old version like 2.5.1; current git needs a very new libdrm to build. -- Jesse Barnes, Intel Open Source Technology Center -- To unsubscribe from this list: send the line "unsubscribe linux-pci" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
