User applications + debugfs? It's not an avenue for ABI. If you really want to provide the settings back to userspace, look at something like an i915_query or sysfs. Or if you just mean igt, then add a Testcase: If you just need to validate that we are setting and restoring them, selftests. If you need them for debugging errors, add them to the error state. -Chris _______________________________________________ Intel-gfx mailing list Intel-gfx@lists.freedesktop.org https://lists.freedesktop.org/mailman/listinfo/intel-gfx
