Description
I'd like to use Sysman API in a container in WSL. I noticed that when I call zesInit() the app segmentation faults.
I used the latest 22.04 container + latest compute-runtime release (https://github.com/intel/compute-runtime/releases/tag/24.09.28717.12).
Container is started like so: docker run -v /usr/lib/wsl:/usr/lib/wsl:ro --device /dev/dxg --rm -it ubuntu:22.04 bash
My app is essentially just a call to zesInit:
#include <zes_api.h>
#include <stdio.h>
int main()
{
ze_result_t res = zesInit(0);
if (res == 0) {
fprintf(stderr, "all good\n");
} else {
fprintf(stderr, "all bad\n");
}
return 0;
}
Compiled with gcc l0.cpp -o l0 -I/usr/include/level_zero -lze_loader
GDB backtrace is like so:
Program received signal SIGSEGV, Segmentation fault.
