The Rockchip fbdev code does not add anything compared to drm_fbdev_generic_setup(); the one custom function for .fb_mmap does the same thing as gem_prime_mmap which is called by the helper.Signed-off-by: John Keeping <j...@metanate.com> --- drivers/gpu/drm/rockchip/Makefile | 1 - drivers/gpu/drm/rockchip/rockchip_drm_drv.c | 10 +- drivers/gpu/drm/rockchip/rockchip_drm_drv.h | 2 - drivers/gpu/drm/rockchip/rockchip_drm_fbdev.c | 164 ------------------ drivers/gpu/drm/rockchip/rockchip_drm_fbdev.h | 24 --- 5 files changed, 2 insertions(+), 199 deletions(-) delete mode 100644 drivers/gpu/drm/rockchip/rockchip_drm_fbdev.c delete mode 100644 drivers/gpu/drm/rockchip/rockchip_drm_fbdev.h diff --git a/drivers/gpu/drm/rockchip/Makefile b/drivers/gpu/drm/rockchip/Makefile index 17a9e7eb2130..1a56f696558c 100644 --- a/drivers/gpu/drm/rockchip/Makefile +++ b/drivers/gpu/drm/rockchip/Makefile @@ -5,7 +5,6 @@rockchipdrm-y := rockchip_drm_drv.o rockchip_drm_fb.o \rockchip_drm_gem.o rockchip_drm_vop.o rockchip_vop_reg.o -rockchipdrm-$(CONFIG_DRM_FBDEV_EMULATION) += rockchip_drm_fbdev.orockchipdrm-$(CONFIG_ROCKCHIP_ANALOGIX_DP) += analogix_dp-rockchip.orockchipdrm-$(CONFIG_ROCKCHIP_CDN_DP) += cdn-dp-core.o cdn-dp-reg.o diff --git a/drivers/gpu/drm/rockchip/rockchip_drm_drv.c b/drivers/gpu/drm/rockchip/rockchip_drm_drv.c index 69c699459dce..20d81ae69828 100644 --- a/drivers/gpu/drm/rockchip/rockchip_drm_drv.c +++ b/drivers/gpu/drm/rockchip/rockchip_drm_drv.c @@ -26,7 +26,6 @@#include "rockchip_drm_drv.h"#include "rockchip_drm_fb.h" -#include "rockchip_drm_fbdev.h" #include "rockchip_drm_gem.h"#define DRIVER_NAME "rockchip"@@ -159,10 +158,6 @@ static int rockchip_drm_bind(struct device *dev)drm_mode_config_reset(drm_dev); - ret = rockchip_drm_fbdev_init(drm_dev);- if (ret) - goto err_unbind_all; - /* init kms poll for handling hpd */ drm_kms_helper_poll_init(drm_dev);@@ -170,10 +165,11 @@ static int rockchip_drm_bind(struct device *dev)if (ret) goto err_kms_helper_poll_fini;+ drm_fbdev_generic_setup(drm_dev, 32);
Please pass 0 for the final argument. The fbdev helpers pick 32 by default. Maybe leave a comment if you require 32 here.
For RGB colors, you should rather set drm_device.mode_config.preferred_depth to 24 instead.
