NVIDIA GRID 6.2

Hi All

Its time to update your NVIDIA TESLA M6, M10, M60, P4, P6, P40, P100, V100 with GRID 6.2

NVIDIA have released new drivers for NVIDIA GRID 6.2 for July 2018.

This release is great as NVIDIA released a 4GB framebuffer for vPC licenses, so customers before couldn only run a framebuffer up to 2GB (in GRID 6.1) before GRID 6.0 max FB was 1GB. This is now this is increased to 4GB with the new -2B4 vGPU type that is available for all licenses. Another great thing for cutomers is support for latest Windows 10 1803 and support for VMware Horizon 7.5  and Citrix XenDesktop/XenApp 7.18 + Citrix XenServer 7.5

Important:

  • If you are a customer using XenServer 7.2 or XenServer 7.3 its no longer supported with NVIDIA GRID 6.2 and should plan upgrading to XenServer 7.4 or 7.5.
  • Customers using Citrix XenServer 7.0 or 7.1 is supported with NVIDIA GRID 6.0
  • NVIDIA GRID 6.2 is only supported with Citrix XenDesktop 7.15, 7.17, 7.18 in HDX 3D Pro mode

This release includes the following software:

  • NVIDIA GRID Virtual GPU Manager version 390.72 for the Citrix XenServer, VMware vSphere, Huawei UVP
  • NVIDIA Windows driver version 391.81
  • NVIDIA Linux driver version 390.75

Autodesk AutoCAD 2016 / 2017 critical hotfix for Citrix customers using NVIDIA or INTEL GPUs

Earlier this year I have seen several customers having issues with AutoCAD in Citrix not defaulting to the primary display adapter, so the GPU wouldn be fully functioning and Autodesk AutoCAD 2016/2017 would turn off hardware acceleration. This issue have been seen on NVIDIA Gpus such as GRID, NVIDIA also have a official KB on this http://nvidia.custhelp.com/app/answers/detail/a_id/4092/ and issue is also seen with INTEL gpu such as Iris Pro Graphics more specific on solutions with HPE Moonshot 710p and 710x.

Issue is identified on both Citrix XenApp 7.x (Windows Server OSs) and Citrix XenDesktop 7.x (Workstation OSs)

“The primary display adapter is not shown as the default in a Citrix environment.”

Google Chrome 45.x Blocks GPU Acceleration for WebGL, Direct2D, DirectWrite with Citrix XenApp on Windows 2008R2/2012/2012R2

Solution: Google Chrome 45.x Blocks GPU Acceleration for WebGL, Direct2D, DirectWrite with Citrix XenApp on Windows 2008R2/2012/2012R2

Google Chrome v. 45  have changed their behaviour of their web browser, so they are blacklisting GPUs, which means hardware acceleration is disabled by default in a Remote session this behaviour is seen in Microsoft RDS with RemoteFX, Citrix XenApp 6.5 -> 7.6 with vGPU/GPU pass-through. Behaviour is also seen on Linux environments with Google Chrome.

Issue highlightet in a Citrix XenApp 7.6 (2008R2/2012/2012R2) with GPU

Open Google Chrome and type in chrome://gpu and then you will see if your RDS/XenApp with a GPU is working or not.
With Google Chrome v 45 the default behaviour is now that Google choose to disabling the GPU.

browser - chrome xa 2012r2 cpu issue - graphics feature issue

Google Chrome experience with a GPU (Citrix XenDesktop vs Citrix XenApp)

browser - chrome xd vs xa gpu - 2008R2 vs Win7

above picture confirms the GPU is not enabled in Google Chrome with RDS/XenApp

interesting is that Multiple Raster Threads in Win7 with a GPU is disable… why lets find out.

This is properly because you haven’t configured the CPU correctly in the hypervisor for the virtual machine.
* hint I did on purpose so you can understand it can be complex to troubleshoot if you don’t configure your environment correctly.

browser - chrome win7 cpu issue fix
best practices with HDX 3D Pro is 4 vCPU and in XenServer 6.5 you configure it 2:2

Then Multiple Raster Threads works in Win7 after you changed the configuration of the CPU on the Win7 vm.

below picture confirms the GPU is not enabled in Google Chrome with RDS/XenApp in Server 2012R2

Now we have validated that the GPU is blacklisted in RDS/XA with a GPU, lets see if we can fix this.

Performance with a WebGL web app in Google Chrome

CPU is very high when the Google Chrome is running the WebGL application. This is because its using the CPU to do software rasterize of the GPU and this makes your user able to run a webgl application without a GPU, but wait. We actually have a GPU in our RDS/XA server now, why is this not offloading the CPU, thats because Google desided to turn off GPU and blacklist them.

browser - chrome xa 2012r2 cpu issue

Solution

  1. Edit Google Chrome link and after the chrome.exe add
    –ignore-gpu-blacklistgooglechrome
  2. Open Google Chrome and run chrome://gpu in the browser
  3. Check if Hardware acceleration is now working for all functions in Google Chrome

browser - chrome xa 2012r2 cpu issue - graphics feature

GPU hardware acceleration is now working in RDS/XA with a GPU in Google Chrome and CPU is now offloaded to the GPU as you can see in the below picture.

Mozilla Firefox 40.x Blocks GPU Acceleration for WebGL, Direct2D, DirectWrite with Citrix XenApp on Windows 2008R2/2012/2012R2

Mozilla Firefox 40.x Blocks GPU Acceleration for WebGL, Direct2D, DirectWrite with Citrix XenApp on Windows 2008R2/2012/2012R2

One of the great things about adding a GPU in a Citrix XenApp environment is that you can allow rich graphics and offload CPU and run your DirectX, OpenGL  applications on a XenApp server. In latest version of Mozilla Firefox WebGL, Direct2D, DirectWrite this have been disabled, so you can’t open webpages that uses these graphics in a Citrix XenApp session.

Symptoms or Error

If you open Mozilla Firefox 40.x and try to open a webGL website like http://madebyevan.com/webgl-water
this will not load anymore cause WebGL is default now disabled in Mozilla Firefox. Mozilla Firefox 40.x  blocks GPU acceleration for WebGL, Direct2D, DirectWrite in remote sessions on Windows Server operating systems.

2015-09-15_1553

To determine what content Firefox is blocking, run Firefox in your XenApp remote session and enter the address about:support into the browser address bar. In the section labelled “Graphics” you will see the following content disabled (as of Firefox version 40.0.3):

Direct2D Enabled             Blocked for your graphics card because of unresolved driver issues.
DirectWrite Enabled         false (6.3.9600.17999)
WebGL Renderer             Blocked for your graphics card because of unresolved driver issues.

2015-09-15_1555

Solution

The text “Blocked for your graphics card” is misleading as, in this case, it is not the specific graphics card but general Windows Server operating system remote sessions that are blocked. Mozilla‚Äôs published advice on how to override the graphics driver blocks also applies to XenApp sessions on workstation operating system (see bottom of this Mozilla Wiki – Blocklisting/Blocked Graphics Drivers).

Enable WebGL in Mozilla Firefox

In Mozilla Firefox entering the address about:config into the address bar and setting webgl.force-enabled=true will enable WebGL for XenApp on operating system (Server 2008R2/2012/2012R2)

webgl

 

You can double click on it and then it will become enabled. (with the value=true) and this is user set.
These settings can be change with a policy or with profile management such as RES Workspace Manager or others.

webgl-working

Now you can open the WebGL demo and the graphics will work

Enable DirectDraw2D

In Mozilla Firefox entering the address about:config into the address bar and setting gfx.direct2d.force-enabled=true will enable WebGL for XenApp on operating system (Server 2008R2/2012/2012R2)

direct2d

You can double click on it and then it will become enabled. (with the value=true) and this is user set.
These settings can be change with a policy or with profile management such as RES Workspace Manager or others.

direct2d-working

Enable DirectDraw2D

In Mozilla Firefox entering the address about:config into the address bar and setting gfx.font_rendering.directwrite.enabled=true will enable DirectWrite for XenApp on operating system (Server 2008R2/2012/2012R2)

directwrite

You can double click on it and then it will become enabled. (with the value=true) and this is user set.
These settings can be change with a policy or with profile management such as RES Workspace Manager or others.

directwrite-working

Users should be aware and note the caveats and warnings that Mozilla advises if taking this route to above settings for DirectWrite, Direct2D, WebGL

This issue only affects server operating system (example – Win 2012 R2 and Win 2008 R2) and XenApp.

How to force-enable blocked graphics features

If you would like to forcibly enable a graphics feature that is blocked on your system, follow these instructions. Warning: do this at your own risk. There usually are good reasons why features are blocked.

To force-enable WebGL, go to about:config and set webgl.force-enabled=true.

To force-enable WebGL anti-aliasing, go to about:config and set webgl.msaa-force=true.

To force-enable Layers Acceleration, go to about:config and set layers.acceleration.force-enabled=true.

On Windows Vista and Windows 7, to force-enable Direct2D Content Acceleration, go to about:config and set gfx.direct2d.force-enabled=true.

On Android, to force-enable StageFright software decoding, go to about:config and set stagefright.force-enabled=true.

On Windows, you can also spoof your graphics system information to help debug driver blacklisting issues (see bug 604771):

  1. Create spoofed-firefox.bat in the installation folder (e.g. C:\Program Files (x86)\Mozilla Firefox)
  2. Set the new values of spoofed variables ending with a command to launch Firefox:
    SET MOZ_GFX_SPOOF_WINDOWS_VERSION=60001
    SET MOZ_GFX_SPOOF_VENDOR_ID=0x8086
    SET MOZ_GFX_SPOOF_DEVICE_ID=0x0046
    SET MOZ_GFX_SPOOF_DRIVER_VERSION=8.15.10.2302
    “C:\Program Files (x86)\Mozilla Firefox\firefox.exe” -p -no-remote
  3. Double-click spoofed-firefox.bat and create a profile if required
  4. Click the Firefox button, then select Help, finally Troubleshooting Information and check the Graphics section.

If force-enabling a feature doesn’t work, that probably means that your hardware doesn’t support it. For example, layers acceleration currently requires support for 4Kx4K textures, which rules out some graphics cards, like the Intel G31/G33.
