NVIDIA received notification of a security exploit that uses NVIDIA UNIX device files to map and program registers to redirect the VGA window. Through the VGA window, the exploit can access any region of physical system memory. This arbitrary memory access can be further exploited, for example, to escalate user privileges.

Because any user with read and write access to the NVIDIA device files (which is needed to execute applications that use the GPU) could potentially exploit this vulnerability to gain access to arbitrary system memory, this vulnerability is classified as high risk by NVIDIA.

NVIDIA is resolving this problem by blocking user-space access to registers that control redirection of the VGA window. Further, NVIDIA is also blocking user-space access to registers that control GPU-internal microcontrollers, which could be used to achieve a similar exploit.

NVIDIA is committed to security and is working on more robust solutions to prevent malicious manipulations of GPUs.

NVIDIA has released an updated UNIX graphics driver 304.32 which contains the fix.

======== Release 304 Entries ========

    * Fixed a bug that caused applications that use DirectColor visuals, such as
      Enemy Territory: Quake Wars and Braid, to appear in shades of blue instead
      of the correct colors.

    * Modified handling of RRSetScreenSize requests to ignore requests that
      do not actually resize the screen.  This reduces screen flicker in certain
      cases when using GNOME.

    * Added a new option, "--disable-nouveau" to nvidia-installer. This
      option changes the action that is chosen by default when Nouveau
      is detected by nvidia-installer. If the "--disable-nouveau" option
      is set, then the default will be to attempt to disable Nouveau when
      it is detected; otherwise, no attempt will be made unless requested.

3D-Tech News Around The Web / Kishonti GLBenchmark 2.5
« on: August 01, 2012, 07:20:54 PM »
GLBenchmark 2.5 is a graphics performance benchmark tool that measures different graphic and computation capabilities of your mobile device. The majority of the tests focus on graphic resources, measuring the quality and performance of the underlying OpenGL ES 2.x implementation.

The benchmark, among other features, contains high-level 3D animations (the new Egypt HD and Egypt Classic from GLBenchmark 2.1) and low-level graphic measurements. GLBenchmark Egypt HD is the upgraded version of the old Egypt 2.1 test: it is more complex, uses more and higher resolution textures and is optimized for 1080p.

The mashed looking screen is an offscreen test.

3D-Tech News Around The Web / HWiNFO32 v4.02 released
« on: July 31, 2012, 06:18:37 PM »
Changes in HWiNFO32 v4.02 - Released on: Jul-31-2012:

    Added support of IRF IR3564.
    Added preliminary support of AMD Mars.
    Added fan speed monitoring on Clevo W860, W870, W880, P150, P170, P180.
    Added preliminary support of AMD Steamroller family.
    Fixed BSOD with certain Intel RST drivers.
    Added support of IRF IR3563 Digital PWM.
    Enhanced sensor monitoring on GIGABYTE Z77X-UP series.
    Added nVidia Quadro K1000M, K2000M, K3000M, K4000M, K5000M.
    Added nVidia GeForce GTX 650M and GeForce GTX 680M.
    Enhanced sensor monitoring on ASUS MAXIMUS V EXTREME and MAXIMUS V FORMULA.


======== Release 304 Entries ========

    * Added support for RandR per-CRTC gamma manipulation through the
      RandR 1.2 RRGetCrtcGammaSize, RRGetCrtcGamma, and RRSetCrtcGamma

    * Fixed a bug that caused RRSetOutputPrimary requests to incorrectly
      generate BadValue errors when setting the primary output to None.  This
      caused gnome-settings-daemon to crash after changing the screen
      configuration in response to a display hotplug or the display change
      hot-key being pressed.

    * Fixed a problem where RENDER Glyphs operations would exhibit severe
      performance issues in certain cases, such as when used with gradients
      by Cairo and Chromium.

    * Fixed a bug that caused X to hang when resuming certain DisplayPort
      display devices (such as Apple brand mini-DisplayPort to dual-link DVI
      adapters) from power-saving mode.

    * Added support for the following GPU:
        * Tesla K10

    * Fixed a bug that caused an X screen to be extended to Quadro SDI Output
      devices by default.  An X screen will still use an SDI Output device if
      it is the only display device available.  To use a SDI Output device on
      an X screen with other display devices available, include the SDI Output
      device with either the "UseDisplayDevice" or "MetaMode" X configuration

    * Updated X11 modeline validation such that modes not defined in a
      display device's EDID are discarded if the EDID 1.3 "GTF Supported"
      flag is unset or if the EDID 1.4 "Continuous Frequency" flag is
      unset.  The new "AllowNonEdidModes" token for the ModeValidation
      X configuration option can be used to disable this new check.

    * Fixed a bug, introduced in the 295.xx release series, with EDID
      detection on some laptop internal panels.  This bug caused the
      laptop internal panel to show six small copies of the desktop.

    * Added support for FXAA, Fast Approximate Anti-Aliasing.

What's your program tool (eVGA Precision, MSI AfterBurner...) you got "6.9 fps"?

Afterburner which has been updated today btw
I took only a quick look yesterday with my NVIDIA rig.

However i'm more curious how much CUDA is actually used.
atm my ATI GPU crashes at the following program counter

3D-Tech News Around The Web / MSI Afterburner 2.2.3 (2012-07-24)
« on: July 24, 2012, 05:27:48 PM »
... Afterburner 2.2.3 official version is ready for you to download. this version supports the control of South Island and Kepler card, if you get the card, you may try to play it.

Changes list includes:

• Revised I2C access API for NVIDIA 301.xx and newer display drivers
• Added core, memory and auxiliary PEXVDD voltage control for custom design MSI N680GTX Lightning series graphics cards with CHL8318+uP6262 voltage regulators
• Added memory and VRM temperature monitoring for custom design MSI N680GTX Lightning series graphics cards with NCT7718W thermal sensors
• Added core, memory and auxiliary PEXVDD voltage control for custom design MSI N670GTX Power Edition series graphics cards with uP6262 voltage regulators


In 2002, NVIDIA released a demo called Dawn to demonstrate the power and programmability of GeForce FX. It showcased a fairy character of extraordinary detail, seamless curves, and lifelike expressions. Among the many technology demos NVIDIA has released before and since, Dawn has remained the most memorable. It was the first time a fully animated and totally credible character was brought to life in real time. Even today, many games have yet to realize a character with Dawn's level of detail.

Fast forward ten years, and NVIDIA has brought back Dawn once again, in a demo simply titled "A New Dawn".

NVIDIA claims Kepler to be required, but it works on Fermi too...
