How to get number of Intel GPUs without dpctl? #1256
Description
Activity
Dpctl uses the dpcpp SYCL runtime, so the count of devices correlate to what the SYCL runtime exposes. For example, you can have a Nvidia GPU on your system, but it will not be counted as a device unless you specially build dpcpp and dpctl with Nvidia support (ref #1124).
If you do not want to use dpctl, then you can use
sycl-lsto get the list of devices that are supported by your SYCL runtime. I do not recommend looking at driver directories as dpcpp can support different types of drivers: opencl, level_zero, cuda, rocm (last two need separate plugins).Converting the issue to a discussion.

Hi,
I have a question about get device count of Intel GPUs.
By using dpctl, I can easily get count with
len(dpctl.get_devices("level_zero", "gpu"))However, using this API should import dpctl,
If I don't want to import dpctl, how can I get the device count?
Like Nvidia GPU detection: by check the driver list in folder
/proc/driver/nvidia/gpusThanks.
