Description Tomi Sarvela 2017-03-21 17:36:50 UTC

This problem is fallout from commit 301ad44cdf1b868b1ab89096721da91fa8541fdc
lib: Open debugfs files for the given DRM device

Error is always the same:
(gem_ctx_basic:6494) igt-debugfs-CRITICAL: Test assertion failure function igt_drop_caches_set, file igt_debugfs.c:964:
(gem_ctx_basic:6494) igt-debugfs-CRITICAL: Failed assertion: fd >= 0
(gem_ctx_basic:6494) igt-debugfs-CRITICAL: Last errno: 2, No such file or directory
Test gem_ctx_basic failed.

Problem in a nutshell:
tomeu> test has a fd for the render node, but wants to tweak the i915_gem_drop_caches file for the legacy device

Does this need to be verified or can we close it?

Comment 3 Lakshmi 2018-08-22 10:52:56 UTC

Closing this bug as there are no failures occurred related to gem_ctx_exec, gem_ctx_param, igt@gem_ctx_create@basic, igt@gem_ctx_create@basic-files settings from CI test results.
