HP Z200 Workstation Bios VT enabled 2 x Intel i5-660 3.33GHz cpu Intel HD Graphics Chipset / i915 / inteldrmfb Bios allocated 256MB to video HP W2408H monitor connected from its hdmi port to motherboard integrated dvi port 8GB DDR3 @ 1333 MHz ram Slackware 14.1 x64 Xen 4.4.0 Lilo + either kernel: Kernel 3.10.17 using default Slackware 14.1 'huge' config - ftp://ftp.slackware.com/pub/slackware/slackware64-14.1/source/k/config-x86_64 Kernel 3.14.13 using Slackware-current (July 23 2014) 'huge' config - ftp://ftp.slackware.com/pub/slackware/slackware64-current/source/k/config-x86_64 Making this system a Dom0 results in poor & slow video performance. Video performance without Xen is normal. Haven't yet determined whether the video problem could be a symptom of some other general system performance issue when running Xen. Xen kernel differs from the original kernel only in that mbootpack ( http://www.tjd.phlegethon.org/software/ ) was used to put kernel + initrd + xen together and prerequisite Xen config options were added per http://wiki.xenproject.org/wiki/Mainline_Linux_Kernel_Configs : CONFIG_HYPERVISOR_GUEST=y (3.10+ only) CONFIG_PARAVIRT=y CONFIG_XEN=y CONFIG_PARAVIRT_GUEST=y CONFIG_PARAVIRT_SPINLOCKS=y CONFIG_HVC_DRIVER=y CONFIG_HVC_XEN=y CONFIG_XEN_FBDEV_FRONTEND=y CONFIG_XEN_BLKDEV_FRONTEND=y CONFIG_XEN_NETDEV_FRONTEND=y CONFIG_XEN_PCIDEV_FRONTEND=y CONFIG_INPUT_XEN_KBDDEV_FRONTEND=y CONFIG_XEN_FBDEV_FRONTEND=y CONFIG_XEN_XENBUS_FRONTEND=y CONFIG_XEN_SAVE_RESTORE=y CONFIG_XEN_GRANT_DEV_ALLOC=m CONFIG_XEN_TMEM=y CONFIG_CLEANCACHE=y CONFIG_FRONTSWAP=y CONFIG_XEN_SELFBALLOONING=y CONFIG_X86_IO_APIC=y CONFIG_ACPI=y CONFIG_ACPI_PROCFS=y (optional) CONFIG_XEN_DOM0=y CONFIG_PCI_XEN=y CONFIG_XEN_DEV_EVTCHN=y CONFIG_XENFS=y CONFIG_XEN_COMPAT_XENFS=y CONFIG_XEN_SYS_HYPERVISOR=y CONFIG_XEN_GNTDEV=y CONFIG_XEN_BACKEND=y CONFIG_XEN_NETDEV_BACKEND=m CONFIG_XEN_BLKDEV_BACKEND=m CONFIG_XEN_PCIDEV_BACKEND=m CONFIG_XEN_PRIVILEGED_GUEST=y CONFIG_XEN_BALLOON=y CONFIG_XEN_SCRUB_PAGES=y The resulting video symptoms occur even with no DomU's running and with xencommons + xendomains stopped - Before starting X while working with console tty's there is ~1 second lag for screen to fully redraw whenever switching between tty's. example - going back and forth via Alt-F1 and Alt-F2 results in a noticeable delay before all text is redrawn on the screen. While in X with only Firefox running, youtube/flash videos are unwatchable especially in full screen, video frames not drawing quickly enough, ends up looking like a flip book of images with some frames missed and the rest going slowly, also leads to Firefox response lag while in full screen, same even at low quality 240p. Full screen videos in mplayer look decent until trying 1080p at which point things become unwatchable and again video appears to be not drawing/refreshing quickly enough to keep up, gets hit with the slow flip book effect. Tried with no improvement: kernel 3.15.x disabled hyperthreading per http://wiki.xen.org/wiki/Tuning_Xen_for_Performance#Hyperthreading_in_Xen_4.3_and_4.4 booting with iommu=no-snoop updated BIOS to 1.21 vga=0x35A adding the following to /etc/X11/xorg.conf: Section "Device" Identifier "Intel Graphics" Driver "intel" Option "AccelMethod" "uxa" EndSection More system info follows, any suggestions would be most appreciated.
