Dear Developers: I am referring to this document https://docs.mesa3d.org/drivers/venus.html#vtest to develop vulkan related functions, but every time I run vulkaninfo or vkcube some errors occur.
virgl_test_server prints the following: gl_version 46 - core profile enabled vtest_client_dispatch_commands: client context created. client failed: VTEST_CLIENT_ERROR_INPUT_READ Running vulkaninfo prints the following: WARNING: [Loader Message] Code 0 : terminator_CreateInstance: Failed to CreateInstance in ICD 0. Skipping ICD. Cannot create Vulkan instance. This problem is often caused by a faulty installation of the Vulkan driver or attempting to use a GPU that does not support Vulkan. ERROR at ./vulkaninfo/vulkaninfo.h:649:vkCreateInstance failed with ERROR_INCOMPATIBLE_DRIVER Running vkcube prints the following: Cannot find a compatible Vulkan installable client driver (ICD). Please look at the Getting Started guide for additional information. After debugging, I found that the error occurred when calling the system function res = read(fd, ptr, left) in the vtest_block_read(struct vtest_input *input, void *buf, int size) function, it returned 0 to the variable res, but The variable left passed in is 8. This is only true if(res == left). And I checked the Requirements by running below command: vulkaninfo | grep "Vulkan Instance Version" vulkaninfo | grep VK_EXT_external_memory_dma_buf vulkaninfo | grep VK_EXT_image_drm_format_modifier vulkaninfo | grep VK_EXT_queue_family_foreign uname -r the output: Vulkan Instance Version: 1.3.204 VK_EXT_external_memory_dma_buf : extension revision 1 VK_EXT_image_drm_format_modifier : extension revision 2 VK_EXT_queue_family_foreign : extension revision 1 5.15.0-52-generic Except the graphics card is GTX 1060 3GB, I think my other requirements are met. I use vtest, which can ignore the kernel version according to the documentation. - When you were testing, what versions of virglrenderer and mesa were you using? If you guys know, please let me know and I will try it again. - If you don't know the specific version, can you give me some debugging or method suggestions? Looking forward to your reply, thank you very much
