      Description

      I got an error when I run cinematic experience on an iMX6.

      EGLPlatformContext: eglSwapBuffers failed: 3003
      Could not lock GBM surface front buffer

      The error appear when I clone two output flow video.

       

      The error is caused by the two commit.

      a5a37a7529 eglfs: kms: Read page flip events on a dedicated thread
      5705133066 eglfs: kms: Make threaded atomic drm work

      When reverted both or one of them the error disappear.
