From db3147b5446334d69d1ffdb07234babc292dec2e Mon Sep 17 00:00:00 2001

Subject: [PATCH 8/8] gl-renderer: Use mailbox streams for scanout
X-NVConfidentiality: public
Ever since flip-event-based output repaints have been used, FIFO mode
for EGLOutput streams was not necessary.
Make the streams operate in mailbox mode. This also fixes certain
interaction issues when recovering from power-saving mode or
vt-switches.
