Can you post the mvisor log? did it output some error information？ |
|
|
|
Oh, maybe the MvisorVGPUx64.dll was not loaded. |
|
|
Use q35.yaml instead of i440fx.
|
|
@purplepalmdash how about other tests in GpuTest ? |
|
all of the tests in GpuTest under current config(i440fx) got the same result(blank window and no result), I'm currently trying the q35 way. |
You can use ProcessHack to check if the guest dll were loaded. |
|
q35 get the same result. Mvisor version: though copied all user dll under gputest, not loaded when running test:
|
GpuTest_GUI would create sub process to test opengl, check if the sub process loaded opengl32.dll. |
|
As you see, the MvisorVGPUx64.dll is the entrance of vgpu device, it implements the opengl api in opengl32.dll and transport all the request to kernel driver(Mvisor VGPU). |
|
both dll(MvisorVGPUx64/opengl32) are loaded.
Seems the virglrender didn't received the commands from guest? |
Close the Gputest.exe, try to disabled the Mvisor VGPU device in device manager, and then enable it. |
Yes, it seems that the vgpu device didn't receive any commands from guest dll. Maybe the vgpu driver did not start. |
|
Hello, I also encountered the same problem. This is the output of dbgview when running gputest. Have you encountered such a situation? |
|
|
Thank you for your reply, I tried restart vm and restart vgpu device, I got the same error when running gputest. |
don't restart vm, just disable the vgpu device and then enable it again. |
I tried disable Mvisor VGPU device and enable it, then run gputest with UAC, but it doesn't work. I use pre-built vgpu-drive and virtio-win-0.1.240, do I need to change the OS? |
|
oh~You may need to debug it why the IOCTL_VIRTIO_VGPU_GET_CAPS got failed. It was the beginning of VGPU initialization. |
Yes, I think so, I'll debug it later, thanks for the advice! |
|
If the driver didn't output anything error, the problem maybe the |
Of course, I will find a free time to test it. |
Hello nooodles, Happy New Year! Recently I try to debug MvisorVGPUx64.dll by following the steps:
At this time I found that gputest did not load MvisorVGPUx64.dll.
I found that the size of MvisorVGPUx64.dll I built was 23MB, but the pre-built dll was only 20MB. My compile command line is as follows: Some environmental information: Did I make a mistake somewhere? |
|
Another question, Can you tell me what the function of opengl32.dll in the pre-built package? It doesn't seem to be used in install.bat. |
so, you made it !!!? |
Yes, the windows already got the openg32.dll in system32, the dll was just a interface collections, it needed implemention from GPU driver. |
|
Yes, I got MvisorVGPUx64.dll from sources code sucessfully and copy it to C:\Windows\System32, but gputest can not load it. |
Thanks, I get it, maybe I don't need to care about opengl32.dll that build from sources. |
Oh, maybe there are some other dlls depended lost. For example, zlib.dll or zstd.dll |
Maybe, I'll check the deps later. |
it's works after add dll deps, i print some information in
But it looks like it returns a handle normally. |
|
I got a specific error when run gputest with MvisorVGPUx64.dll in debug mode: My device manager: My mvsior vm config: Can you give me some advice? |
failed=31 means that the vgpu device didn't work. it was windows error. Print the handle value |
I have no idea with this now, have you modified the code about stw_pf_color?But it seems the gpu device worked |
I haven't modified the code about stw_pf_color, i think i need debug it again. |
I also encountered this error, is there any solution now? |
Sadly not yet, I know nothing about windows, I'm learning it |

Hi, I installed the prebuilt driver in win10 vm, but gputest could not use this device, during the test it shows nothing then exit.
From the issue #1 you could see GpuTest could detect graphical infos during testing , but in my vm it show nothing, just a blank window then exit.
From the mvisor's log I couldn't find any log related to
virtio_vgpu.cclike in #1Mvisor VGPUdevice seems OK in device manager:My enviroment is listed as following:
nvidia-smi output:
vgpu config:
Any suggestions?
