From 35f4f8c9fc972248055096d63b782060e473311b Mon Sep 17 00:00:00 2001 From: Maíra Canal Date: Wed, 3 Apr 2024 17:24:50 -0300 Subject: drm/v3d: Don't increment `enabled_ns` twice MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit The commit 509433d8146c ("drm/v3d: Expose the total GPU usage stats on sysfs") introduced the calculation of global GPU stats. For the regards, it used the already existing infrastructure provided by commit 09a93cc4f7d1 ("drm/v3d: Implement show_fdinfo() callback for GPU usage stats"). While adding global GPU stats calculation ability, the author forgot to delete the existing one. Currently, the value of `enabled_ns` is incremented twice by the end of the job, when it should be added just once. Therefore, delete the leftovers from commit 509433d8146c ("drm/v3d: Expose the total GPU usage stats on sysfs").
