Since this PR https://github.com/apache/incubator-tvm/pull/2111 was closed, I remember @cbalint13 took over the PR. I wonder what happened since then? Are there still interest in integrating x86 winograd?
Recently I got an access to Cascadelake with VNNI instruction, and that revived my interest in Winograd (I had some experience in the past). If I find enough time, I may be able to work on it.
