arb_framebuffer_object: Add a test for blit-based mipmap generation (!428) · Merge requests · Mesa / piglit

Chia-I Wu requested to merge olv/piglit:blit into master Dec 08, 2020

This currently passes on i965 but fails on iris. This mimics virglrenderer which translates guest glGenerateMipmap to blit-based mipmap generation.

I am not confident in my GL understanding. Let me know if the test is wrong and I will go fix virglrenderer.
