Gpumodeswitch用于Hyper-V 2016上GPU的Passthrough（DDA）

嗨蒂姆，
用不同的线程提出不同的问题是没有意义的。
Q1->图形模式
Q2->已经回答了。
对于VDI，如果没有QvDWS，这将是一个问题，但对于RDSH，这是可以的。
Q3->取决于几个因素。
视频播放总是需要CPU，因此它取决于主机上运行的会话计数和可用资源。
一般来说，全屏视频播放并不是什么大问题。
Q4->重要的是在视频播放器中启用硬件解码，尤其是对于使用H264的视频。
如果我们谈论Youtube视频，您应该确保您的浏览器使用H264ify插件在硬件中解码，这在性能和播放方面产生巨大差异。
问候
西蒙

Hi Tim,

It makes no sense to ask different questions with different threads.
Q1->Graphics Mode
Q2->Already answered. For VDI this would be an issue without QvDWS but for RDSH this is OK.
Q3->Depends on several factors. Video Playback always needs also CPU so it depends on the session count running on the host and available resources. In general fullscreen video playback is not a big deal.
Q4->Important do enable hardware decode in the video player especially for videos that use H264. If we talk about Youtube videos you should make sure that your browser uses H264ify plugin to decode in hardware which makes a huge difference in performance and playback.

When I tried to use the gpumodeswitch.exe command line utility it does these things on the HOST of the machine....

gpumodeswitch.exe --listgpumodes (will crash)
gpumodeswitch.exe --gpumode graphics (will give this error message below)

ERROR: Unable to setup NVFLASH driver (0x00000020)
Detailed :The process cannot access the file because it is being used by another process.

I know that you said in the other thread that my GPU is new and it's already in graphics mode, but I am just checking to see if there is something wrong with my card.

I have shutdown the VM's and rebooted the host and I am still getting these messages.

你需要先卸载vGPU管理器。
如果您的电路板处于图形模式，请简单地检查lspci。
这样更容易......
lspci -n |
grep 10de（应该有类300）
问候
西蒙



以下为原文

Tim,

you would need to uninstall vGPU manager first. Please simply check with lspci if your board is in Graphics mode. This is way easier...
lspci -n | grep 10de (should have class type 300)

我没有使用linux而且我无法访问grep。
有没有办法在Windows中使用才能找到答案？
另外，当我全屏播放视频时，我的速度有些慢。
我知道GPU正在运行，因为我正在运行GPU分析器，我发现它使用5-10％的GPU来渲染DIVX 1080P视频，但如果我全屏显示，有时会有一些暂停。
如果我在一个窗口中这样做，它工作正常。
知道为什么会这样吗？
此外，也许我需要使用另一个播放器而不是VLC（打开硬件加速）。
也许k-lite Codec Pack PLUS附带的播放器会更好吗？



以下为原文



I'm not using linux and I don't have access to grep.  Is there a way that I can use in Windows to find out?

Also, I am having some slowness when I play videos in full screen.  I know that the GPU is working because I am running a GPU profiler and I see that it's using 5-10 percent of the GPU to render a DIVX 1080P video, but if I do it full screen there are some pauses sometimes.  If I do it in a window, it works fine.

Any idea why this would be?

Also, maybe I need to use another player instead of VLC (with hardware acceleration turned on).  Would maybe the k-lite Codec Pack PLUS the player that comes with it be better?

您需要在虚拟机管理程序级别检查图形模式，而不是在VM中检查。
由于您没有使用Citrix / VMware的VDI解决方案，我认为您的问题不是GPU而是远程端点的远程处理。
您可以尝试Splash作为视频播放器，也可以使用FRAPS获取视频帧速率。
在大多数情况下，GPU渲染的帧数不够多，但远程处理“太慢”无法获得到终点的恒定30fps，因此您会看到缺乏/口吃。

以下为原文

You need to check Graphics mode on hypervisor level and not within a VM. As you don't use a VDI solution from Citrix/VMware I would assume that your issue is not the GPU but the remoting to the endpoint. You could try Splash as video player and also use FRAPS for getting the video framerate. In most cases the GPU renders more than sufficient frames but the remoting is "too slow" to get the constant 30fps to the endpoint and therefore you see lack/stuttering.

好吧，这是有道理的，它是远程软件的缓慢。
你知道它是否归结为远程桌面客户端的版本？
因为我在6.1版本（Windows 7 Embedded）上进行了测试，并且它非常不稳定，但Windows 10版本的性能要好得多，而且版本是10.xxx。
我之前问过这个问题，但没有人回答我......
在执行DDA和remotefx时，是否需要执行此操作所需的推荐或必需的远程桌面客户端？
至于图形模式。
我在HyperVisor上使用该实用程序（Windows Server 2016上的HyperV），但我刚收到该错误，我无法看到它的模式。我假设显卡是因为它是一张新卡。
关于直通GPU支持，我可以使用的任何其他技巧？
是否有一个开源远程桌面软件（客户端）使用比微软更新的技术，可能会更好？



以下为原文

Okay, that makes sense that it's the slowness of the remoting software.  Do you know if it comes down to the version of remote desktop client in general?

Because I tested this on a 6.1 version (Windows 7 Embedded) and it was super choppy, but the Windows 10 version was a lot better on performance and that version was 10.xxx something.

I have asked this before, but nobody has answered me...

When doing DDA and remotefx is there a recommended or required Remote Desktop Client that is needed to do this?

As far as the graphics mode.  I was using the utility on the HyperVisor (HyperV on Windows Server 2016), but I just got that error and I couldn't see what mode it was in.  I assume graphics because it's a new card.

Any other tips that I can use regarding passthrough GPU support?

Is there maybe an open source Remote Desktop Software (client) that uses newer technology than Microsoft that might work better?

你是对的。
在Win7上，RDP 10.x的性能远远优于RDP。
不幸的是，没有比RDP10.x更好的“免费”了。为了获得最佳性能，您需要Citrix / VMWare / Nice的其他软件...以获得额外费用。
问候
Simonn



以下为原文

You're right. RDP 10.x performs much better than RDP on Win7.
Unfortunately there is nothing better "for free" than RDP10.x For best performance you would need additional software from Citrix/VMWare/Nice... for additional costs.

我看了一下GRID打包和许可指南，我知道我们需要GRID虚拟应用程序的永久并发用户许可证，您只需支付一年的SUMS费用，但我不知道如何开始使用
找到如何购买此许可证。



以下为原文

I took a look at the GRID Packaging and Licensing Guide and I know we want the Perpetual Concurrent User License for the GRID Virtual Applications which you have to pay the SUMS fee for just one year, but I don't know how to get started on finding how the purchase this license.

您可以直接向大多数OEM购买GRID许可证，或者联系NPN首选合作伙伴。

You can buy GRID licenses directly with most of the OEMs or you contact a NPN preferred partner.
