These devices do not need to return to non-graphic console for suspend, so disable that option. This means there is less work to do in the suspend/resume cycle, making it smoother and cheaper. Signed-off-by: NeilBrown <neil@xxxxxxxxxx> -- Hi Tomi, I wonder if you would consider this patch too. It works for me and removes pointless vt switching. I assume no-one would need or want that switching on suspend/resume but I guess I cannot be certain. Maybe a module-parameter could be used if there was any uncertainty. thanks, NeilBrown diff --git a/drivers/video/fbdev/omap2/dss/dpi.c b/drivers/video/fbdev/omap2/dss/dpi.c index f83e7b030249..4a29bab4ade3 100644 --- a/drivers/video/fbdev/omap2/dss/dpi.c +++ b/drivers/video/fbdev/omap2/dss/dpi.c @@ -32,6 +32,7 @@ #include <linux/string.h> #include <linux/of.h> #include <linux/clk.h> +#include <linux/suspend.h> #include <video/omapdss.h> @@ -798,6 +799,8 @@ static int omap_dpi_probe(struct platform_device *pdev) mutex_init(&dpi->lock); dpi_init_output(pdev); + /* No need to vt_switch in suspend/resume */ + pm_set_vt_switch(0); return 0; }
