Set the preferred depth from the format of the scanout buffer. The value cannot be hardcoded, as the scanout buffer is only known at runtime. Also derive the fbdev emulation's bpp value from the scanout format. v2: * fix commit-message typo Signed-off-by: Thomas Zimmermann <tzimmermann@xxxxxxx> Reviewed-by: Javier Martinez Canillas <javierm@xxxxxxxxxx> Acked-by: Daniel Vetter <daniel.vetter@xxxxxxxx> --- drivers/gpu/drm/tiny/simpledrm.c | 4 ++-- 1 file changed, 2 insertions(+), 2 deletions(-) diff --git a/drivers/gpu/drm/tiny/simpledrm.c b/drivers/gpu/drm/tiny/simpledrm.c index 162eb44dcba89..30e928d627e8f 100644 --- a/drivers/gpu/drm/tiny/simpledrm.c +++ b/drivers/gpu/drm/tiny/simpledrm.c @@ -739,7 +739,7 @@ static struct simpledrm_device *simpledrm_device_create(struct drm_driver *drv, dev->mode_config.max_width = max_width; dev->mode_config.min_height = height; dev->mode_config.max_height = max_height; - dev->mode_config.preferred_depth = format->cpp[0] * 8; + dev->mode_config.preferred_depth = format->depth; dev->mode_config.funcs = &simpledrm_mode_config_funcs; /* Primary plane */ @@ -834,7 +834,7 @@ static int simpledrm_probe(struct platform_device *pdev) if (ret) return ret; - drm_fbdev_generic_setup(dev, 0); + drm_fbdev_generic_setup(dev, drm_format_info_bpp(sdev->format, 0)); return 0; } -- 2.38.1
