A prebuilt busybox isn't currently available, but we could publish one. Is there a central location for the qemu community to get these? Or is it expected that each target has their own? Note that this series implements a subset of the instructions. I plan to submit the others once this series is accepted. So, I wouldn't be surprised if busybox doesn't work with this series. I know that it works with the full set of instructions implemented at https://github.com/quic/qemu. In fact, we demo'ed it during our talk at the 2019 KVM Forum https://www.youtube.com/watch?v=3EpnTYBOXCI&list=PLW3ep1uCIRfwwtvUS1Pco6Y0X-5tykpyG&index=33. > > Also I noticed these sample apps: > https://developer.qualcomm.com/software/hexagon-dsp-sdk/sample-apps > > These could be nice to have as integration testing: > > - appi_fir > APPI-based module that applies a FIR filter to audio data > - image downscale > Example showing deeply optimized 2D image downscaling function > - cornerApp > Example that detects corners in an image, using aDSP FastCV primitives All of the SDK examples run on our RTOS, not linux-user. I could convert some of them to work in linux-user mode. Would tests/tcg/hexagon be the right place for these? > Any other real-world binary you could share? In addition to busybox, we could build other open source packages. Would that be of interest? Thanks, Taylor
