Then I run i915 self-test case "igt_ctx_readonly" in KVMGT's guest. The case doesn't report any errors. Can I know if there are any other reasons that you think GVT breaks read-only support? I thought it was from a ci result, but going back through the logs we have never run the selftests at that time under CI. So call it a lack of testing and a misread of the code. igt_ctx_readonly should be sufficient to prove the test, except it needs a bit of refinement to be stricter over hang detection. https://patchwork.freedesktop.org/patch/256433/ -Chris _______________________________________________ Intel-gfx mailing list Intel-gfx@xxxxxxxxxxxxxxxxxxxxx https://lists.freedesktop.org/mailman/listinfo/intel-gfx
