After grepping the OMAP4 kernel, I found some code was commented in the
driver:
drivers/video/omap2/dss/dispc.c
----
if (errors & DISPC_IRQ_SYNC_LOST_DIGIT) {
DSSERR("SYNC_LOST_DIGIT\n");
/*commenting below code as with 1080P Decode we see a sync lost digit for
first frame as it takes long time to decode but it later recovers*/
#if 0
struct omap_overlay_manager *manager = NULL;
bool enable = false;
DSSERR("SYNC_LOST_DIGIT, disabling TV\n");
for (i = 0; i < omap_dss_get_num_overlay_managers(); ++i) {
struct omap_overlay_manager *mgr;
mgr = omap_dss_get_overlay_manager(i);
if (mgr->id == OMAP_DSS_CHANNEL_DIGIT) {
manager = mgr;
enable = mgr->device->state ==
OMAP_DSS_DISPLAY_ACTIVE;
mgr->device->driver->disable(mgr->device);
break;
}
}
if (manager) {
struct omap_dss_device *dssdev = manager->device;
for (i = 0; i < omap_dss_get_num_overlays(); ++i) {
struct omap_overlay *ovl;
ovl = omap_dss_get_overlay(i);
if (!(ovl->caps & OMAP_DSS_OVL_CAP_DISPC))
continue;
if (ovl->id != 0 && ovl->manager == manager)
dispc_enable_plane(ovl->id, 0);
}
dispc_go(manager->id);
mdelay(50);
if (enable)
dssdev->driver->enable(dssdev);
}
#endif
}
----
I am not sure about that.
