Trouble to install driver from release #5
Comments
|
Update, I was able to compile kernelmode and usermode, For usermode: need to perform some move to use a more recent version of flex and bison (use win-bison and win-flex, add a new environment variable path to this installation, rename winbison and winflex to bison and flex). Compilation completes For kernelmode: I found my issues, Certificate issue (as I do not know the password for the provided pfx file) I created via VS2022 my personal certificate by opening vgpu properties then Configuration properties>Driver signing>General : for the option Test certificate it will be written Tenclass.com [......], change this value to "Create test certificate", VS2022 will create a test certificate for you. Then update the file digest algorithm to SHA256 (as requested by VS 2022). Now you can compile the solution. I have all the required file, but, same behavior, Windows can not load my driver.

Oh, if you have compiled them successfully, the problem may be the OS environment. |
|
for the BSOD, I will try to reproduce it with the 21H2 version |
|
I tested the 22H2 and got BSOD just before entering installation program, am not sure it's related to vgpu driver but more on mvisor itself : like this issue : tenclass/mvisor#1 (comment) Best regards, Nikos |

Got the same BSOD with virtio-block config, if you think this BSOD is similar to the one provided in my previous post, should we switch to this issue to diagnose the BSOD issue ? (to avoid poluting this issue) |
Post your host environment in detail. I will test it later. |

Here are the requested details : OS : Elementary 7.1 (based on Ubuntu 22.04.x LTS) To be noted, I do not have to patch src/vrend_renderer.c as it already contains the corresponding line : However, I built and installed it : Nikos |
Thank you for your patient assistance. as you see, AMD gpu doesn't need to be patch the libvirglrenderer to use BLOB feature.

I successfully compiled the user mode driver using mingw64. Using VS2019 was a waste of time. It generated a lot of compilation errors: VS2019 is more strict than GCC. Now I try to compile the kernel mode driver using VisualStudio 2019. Can you specify which VisualStudio version you used to successfully build the Kernel Module? I do have access to a Windows 11 machine. I can install teh latest VS2022 on it. However, I want to generate a driver than will run on Windows 10. |
VS2019 + WDK10.0 |
I faced this issue too, when installing Windows Driver Kit and Visual Studio 2019, it appears that Windows Driver Kit was not properly registered in Visual Studio 2019. You'll have a special program in the start menu that will perform the correct registration. Regards, Nikos |

#2 I have fixed it in release v1.0.1 |

Hello Team,
I try to install the provided driver from release pages, the following error occured :
Please find the VM Yaml configuration :
Windows version : Windows 10 Pro (1809 OS Build 17763.1)
To be noted, I was not able to install Windows 10 via Mvisor due to BSOD on installation, I had to create a VM on Qemu and then use the qcow2 file with mvisor.
Here are the steps I followed, to install the provided driver :
kernelmodeandusermodefolder toc:\windows\system32.I also tried to compile driver, usermode does not seem to compile via Visual Studio 2022 (an issue with target architecture not set), and with kernelmode, it compiles up to file/step 583 then freeze.
Best regards,
Nikos
