When I installed vulkan on ubuntu20.04, nvidia-driver: 510.47.03, vulkan could not recognize the server's graphics card.
Source code compilation Vulkan-SDK and change different versions of vulkan

Depending on the CPU architecture, some computers can run software with some specific instruction set. Using these instructions can greatly improve the speed of the program, but can also lead to crashes when not supported.
But sometimes, when shipping a software that depends on external libraries (binaries), we may want to check what instruction set they rely on (like AVX2, SSE2, etc) and assess if we can use safely this library or executable (e.g.: on Windows, a .lib, .dll or an .exe). Mostly when the final executable has to be shipped to hardware that is out of our control, but should follow some specifications.
Most of the related questions seems to tackle the problem the other way around: from the software, to check if a set of instruction is supported on the current hardware:
how verify that operating system support avx2 instructions
Detecting SIMD instruction sets to be used with C++ Macros in Visual Studio 2015
How one can check, from the binary, what kind of instruction sets are required or used? Is there some OS tools for that?
The OSs of interest would be Windows, Linux and MacOS.
According to this Vulkan tutorial, I can use vkEnumeratePhysicalDevices to get a list of available GPUs. However, I don't see my external NVIDIA GPU in there, only my Intel iGPU.
This eGPU is connected via Thunderbolt and is running CUDA code just fine. Is there anything I might have missed? Is it supposed to work out of the box?
My machine is running Arch Linux with up-to-date proprietary NVIDIA drivers.
The eGPU is a NVIDIA GTX 1050 (Lenovo Graphics Dock). Is it possible that it just does not support Vulkan somehow?
Vulkan support should work just as well with external GPUs (eGPUs). Seeing the eGPU enumerated as a Vulkan device may require the eGPU to be recoznized by Xorg (or Wayland in the future).
See recently created https://wiki.archlinux.org/title/External_GPU#Xorg for changes probably required in Xorg config.
I tried to run the Vulkan cube example after downloading the Vulkan SDK but get the following
vkEnumerateInstanceExtensionProperties failed to find the VK_KHR_surface extension.
Do you have a compatible Vulkan installable client driver (ICD) installed?
I have a Nvidia GK107M [Geforce GT 755M] graphics card.
Regarding the graphics driver, the output of
lshw -c video | grep 'configuration' is
configuration: driver=nvidia latency=0
configuration: driver=i915 latency=0
And when I see through the driver manager it shows Nvidia-352 graphics driver. Earlier I was using Nouveau display driver which I disabled thinking that it might not support Vulkan and the Nvidia driver would. But still the same thing persists.
On running .\vulkaninfo I got a message saying that vulkan instance creation failed with VK_ERROR_INCOMPATIBLE_DRIVER.
P.S: I am using the latest Vulkan SDK releases today only. I am going to try the older SDK versions. Maybe they would work.
P.P.S: I have run into a black /blank screen issue after updating Nvidia driver to 370 and rebooting.
Optimus. Well, there you have it. To quote directly from the driver package documents:
Some designs incorporating supported GPUs may not be compatible with the NVIDIA Linux driver: in particular, notebook and all-in-one desktop designs with switchable (hybrid) or Optimus graphics will not work if means to disable the integrated graphics in hardware are not available. Hardware designs will vary from manufacturer to manufacturer, so please consult with a system's manufacturer to determine whether that particular system is compatible.
So, you need to disable it (in BIOS) if possible (as it says above).
Or get updated driver from the notebook manufacturer (Well, as much chance as seeing Android update on chinatablet. If they even bother with linux support.).
Or expect exactly the kind of problems and hackery with no guaranteed success you face.
The v352 driver you have wouldn't support Vulkan. It is older than Vulkan.
Nouveau to my knowledge doesn't support Vulkan (yet) either.
There's 3 places that the Vulkan loader looks to find a Linux driver's JSON definition file:
/etc/vulkan/icd.d
/usr/share/vulkan/icd.d
And wherever you define "VK_DRIVERS_PATH" to.
If you don't have a JSON in one of those locations for your Nvidia driver that would be a problem.
Secondly, if you do have the JSON file, but it's "library_path" entry doesn't point to a valid driver, that would also not work.
Try looking for those files.
I want to build a sample included in Vulkan SDK.
I downloaded the SDK from http://vulkan.lunarg.com and install it.
Then I opened the Visual Studio (I have a 2013 version), I open the solution from this path: (C:\VulkanSDK\1.0.13.0\Demos). I choose DEMOS.sln file. Then when I click on LocalWindowsDebugger this message pops up:
vkCreateInstance Failure:
vkEnumerateInstanceExtensionProperties failed to find the VK_KHR_surface extention.
Do you have a compatible Vulkan installable client driver (ICD) insatalled? Please look at the Getting Started guide for additional information.
I have never worked with vulkan, but as it named "Demo", I think that everything inside of it should be set in order to work.
I searched the web, but as it is new, there are few resources talked about it.
What is ICD? and how to install it? (is it different from installer of VulkanSDK?) OR this error is about completely different property? like setting properties of VisualStudio?
ICD is basically your GPU driver...
Both the SDK and driver install vulkaninfo app. Use it to determine what extensions you have and whatnot.
BTW Some time ago AMD drivers forgot to export the extensions like VK_KHR_surface. Make sure you are using the latest driver (16.5.2.1 on AMD and 365.19 on NVIDIA as of time of writing).
Also you need supported GPU. Consult:
NVIDIA supported GPUs
AMD supported GPUs
Khronos maintained list
BTW: All the demos work for me.
Do you have a compatible Vulkan installable client driver (ICD) installed?
This message tells you that Vulkan's loader wasn't able to find a Vulkan driver on your device. ICD is the installable client driver that comes with the driver of your graphics card.
What GPU are you using and do you have a driver installed that actually supports Vulkan? Note that while your card may support OpenGL it may not support Vulkan.
Check NVIDIA(performance mode) is selected at "Nvidia X Server Settings" application if you are using ubuntu.
I have Spectrum Digital evaluation board (evm816x).
I have the problem, when i'm trying to port vxWorks 6.9 to the TMS320DM8168(davinci).
I load u-boot to NAND, it starts, all okey. Then, I load vxWorks image with xds510 usb emulator. All okey, vxWorks works good. Then, i'm trying to start vxWorks from u-boot, its crashing through initialization process.
After a few experiments I came to conclusion that vxWorks start only after CPU reset.
What prevents loading vxWorks in CPU?
Thank you.
Generally VxWorks 6.x BSPs are not designed to work with U-Boot. You may encounter random crash using the U-Boot go/bootelf/bootvx command after loading the VxWorks kernel. The reasons behind this might be different, for example it might be due to disagreement with the physical memory address configured in U-Boot, or inconsistent cache/MMU state.
The latest VxWorks 7 supports U-Boot as the bootloader by default on ARM and PPC targets.
Patches are now in the mainstream of the U-Boot Git repo since U-Boot v2014.01 relesae.
There may be bootable and loadable vxworks images. You are probably run loadable image. That is the default option to build vxworks in workbench. That image expects some initialization to be done by bootloader (which is bootable vxworks that runs the "boottask", which in turn loads the vxworks image).
In short, try to build bootable/romable vxworks image and to load it. Otherwise load the bootloader (bootrom) image which will load your loadable vxworks image.
