请教一下 redroid 支持 vgpu 吗

[ctaoist]

pve 起了一个 ubuntu 20.04，分配了一个 vgpu，型号 P4-2Q，运行一个游戏，使用 nvidia-smi 查看，没有任何进程占用 vgpu，显存也没有任何的消耗：

For Nvidia GPU, virtio-gpu is recommended.

如果只分配 virtio-gpu 这个显卡的话，容器可以启动，但 adb 连不上。如果分配 vgpu，游戏动画有点卡顿

[zhouziyang]

Possible software rendering is performed while vgpu is used.

Did you correctly setup virtio-gpu in host (qemu or libvirt)?

连接容器后 dmesg -T|grep gpu 结果：

只有一个端口，外部使用 adb connect ip:5555 连不上，正常情况下应该还有一个端口的，好像是 5357 之类的来着

虚拟机里正确识别出virtio-gpu得卡了吗 lsgpu看下

虚拟机里应该是识别到了 virtio-gpu 的卡，现在只保留了 virtio-gpu，删掉了 VGPU：

Not really related but does the passthrough GPU need hardware encoders for androidboot.redroid_gpu_mode=host to work?

[zhouziyang]

@ForsakenRei Proprietary Nvidia drivers for Android required (the open source nouveau possible works)

Uh, I had some really bad experiences with Nvidia driver on Linux recently, have a RX 6400 lying around and wondering if it will work for redroid. It doesn't have hardware encoders so streaming is a no go, but I guess GPU rendering for redroid will probably be fine?

[zhouziyang]

AMD / Intel GPUs should work out of the box.

Got it working perfectly, thanks!

[wangruiqi-git]

哥 你pve不起ubantu能直接运行redroid吗？

[wangweijun007]

I have the same problem. Nvidia1050TI, pve(vgpu)+ubuntu(vm)+docker+redroid. use androidboot.redroid_gpu_mode=host can not connect ip:5555. change androidboot.redroid_gpu_mode=guest could connect。
