commit ea1f76f9809974f20c0451d4625040e97566796a Author: Derek Foreman <[email protected]> Date: Mon Nov 20 16:53:31 2017 -0600 drm ee: Allow more than 4 buffers Multi-head is hitting corner cases where there are lots of locked buffers and it looks like right now 5 is the magic number that makes the problem go away. Make it possible to set 5 or more (via env var) for testing, make a macro for MAX_BUFFERS instead of just a number. --- src/modules/evas/engines/drm/evas_engine.h | 4 +++- src/modules/evas/engines/drm/evas_outbuf.c | 2 +- 2 files changed, 4 insertions(+), 2 deletions(-) diff --git a/src/modules/evas/engines/drm/evas_engine.h b/src/modules/evas/engines/drm/evas_engine.h index c19ac4c369..af9cc4da3d 100644 --- a/src/modules/evas/engines/drm/evas_engine.h +++ b/src/modules/evas/engines/drm/evas_engine.h @@ -41,6 +41,8 @@ extern int _evas_engine_drm_log_dom; # endif # define CRI(...)
