Does WSL2 support GPU acceleration for launching Android emulators? #13671
Description
Is your feature request related to a problem? Please describe.
I built an AOSP Android image based off Android 14.0.0_r66. I launch the built emulator with cvd start --report_anonymous_usage_stats=n --daemon --start_webrtc=true --run_adb_connector=true. Everything works fine, except that it complains the GPU acceleration is not available and switches to a software rendering.
cvd start --report_anonymous_usage_stats=n --daemon --start_webrtc=true --run_adb_connector=true
...
GPU auto mode: did not detect prerequisites for accelerated rendering support, enabling --gpu_mode=guest_swiftshader.
GPU vhost user auto mode: not needed for --gpu_mode=guest_swiftshader. Not enabling vhost user gpu.
Describe the solution you'd like
Not sure why cvd start cannot detect the GPU acceleration. It should detect it automatically.
Describe alternatives you've considered
Running with --gpu_mode=gfxstream
