Has it always failed? Is it 100% reliable? Has CNL changed the GTT implementation compared to the other Big Core? That is the ultimate question, whether we need to apply the w/a to CNL as well. Hello Chris, Yes, it is failing 100% of the times, We don't have any record that this test was success before. Regards. The following test case is failing on BXT igt@gem_mmap_gtt@coherency IGT-Version: 1.20-g39ac6b8 (x86_64) (Linux: 4.15.0-rc2-drm-intel-qa-ww49-commit-bdf9b36+ x86_64) (gem_mmap_gtt:4141) CRITICAL: Failed assertion: cpu[x] == i *** This bug has been marked as a duplicate of bug 100587 *** Now treating CNL as equally incoherent as Atom. |
