Linux vGPU支持NVIFR吗？

是。
vGPU支持NVIFR和NVFBC。
是的，vGPU可用并支持。
使用4K显示器有一些许可证要求（Workstation Extended的一项功能），但这与NVENC是分开的。



以下为原文



Yes. NVIFR and NVFBC are both supported in vGPU.



Yes it is available and supported for vGPU.

There are some license requirements for the use of 4K displays (a feature of Workstation Extended), however this is separate to NVENC.

你好Jason_Southern，
谢谢你的回答，这真是个好消息！
但我与我们的开发人员进行了对话。
他们对Linux NVENC支持有疑问：
我们正在使用CUDA访问Linux的NVENC编码器。
但Linux vGPU不支持CUDA ...（我看到它只支持1个vGPU = 1 GPU模式，所以它类似于gpu passthrough。）但我不确定。
结果我有很多问题：
1.是否为vGPU linux vms启用了CUDA？
哪些vGPU类型有CUDA支持？
2.是否可以/如何在没有CUDA的情况下访问Linux vGPU vm上的硬件h264编码器？
3.有没有办法为没有CUDA的h264编码器提供OpenGL缓冲？
先谢谢你。

Hello Jason_Southern,

Thank you for your answer, it is really great news!

But I had conversation with our developers. They have doubts about Linux NVENC support:
We are using CUDA to access NVENC encoder for Linux. But CUDA is not supported for Linux vGPU... (I see it supported for 1 vGPU = 1 GPU mode only, so it is similar to gpu passthrough.) But I am not sure about that.

As result I have bunch of questions:
1. Is CUDA enabled for vGPU linux vms? Which vGPU types have CUDA support?

2. Is it possible/How to access hardware h264 encoder on linux vGPU vm without CUDA?

3. May be there are way to provide OpenGL buffers to h264 encoder without CUDA?

Thank you in advance.

CUDA目前仅适用于Passthrough，M60-8Q和M6-8Q配置。
在其他vGPU配置文件中，它将需要用于CUDA的下一代GPU架构。
所有vGPU实例都支持NVENC。
有关NVENC SDK的查询，他们需要访问https://devtalk.nvidia.com/
其他ISV在vGPU会话中使用NVENC，所以是的。
您可能还想参考GRID SDK以获取可能的示例。



以下为原文

CUDA  is currently only available in Passthrough, M60-8Q and M6-8Q configurations. It will require the next generation GPU architecture for CUDA in other vGPU profiles.

NVENC is supported in all vGPU instances.

For queries on the NVENC SDK they need to go here https://devtalk.nvidia.com/


Other ISV's are using NVENC in vGPU sessions, so yes it is possible. You may want to refer to the GRID SDK as well for possible examples.

你好Jason_Southern
我看到其他人已经在devtalk论坛上发布了主题，但没有人回答。
对于那些问题，您可能会推荐人吗？
https://devtalk.nvidia.com/default/topic/903396/gpu-accelerated-libraries/nvenc-linux-without-cuda-dependency/
在我看来，GRID SDK也依赖于NVENC问题。
（没有CUDA就不可能使用）
是否可以直接将此问题转发给NVENC开发人员？



以下为原文

Hello Jason_Southern

I see someone else already posted topic on devtalk forum, but nobody answer. May be you may recommend person for those questions?


https://devtalk.nvidia.com/default/topic/903396/gpu-accelerated-libraries/nvenc-linux-without-cuda-dependency/


It seems to me GRID SDK have dependency on NVENC issue too. (it is not possible to use without CUDA)

Is it possible to forward this question directly to NVENC developers please?
