Exynos does not use damage handling, so DRM's fbdev helpers are mere wrappers around the fbdev code. By using fbdev helpers directly within each DRM fbdev emulation, we can eventually remove DRM's wrapper functions entirely. v4: * use initializer macros for struct fb_ops v3: * don't reorder Makefile rules (Sam) v2: * use FB_IO_HELPERS option Signed-off-by: Thomas Zimmermann Acked-by: Sam Ravnborg Cc: Inki Dae Cc: Seung-Woo Kim Cc: Kyungmin Park Cc: Krzysztof Kozlowski Cc: Alim Akhtar --- drivers/gpu/drm/exynos/Kconfig | 1 + drivers/gpu/drm/exynos/exynos_drm_fbdev.c | 9 ++++----- 2 files changed, 5 insertions(+), 5 deletions(-) diff --git a/drivers/gpu/drm/exynos/Kconfig b/drivers/gpu/drm/exynos/Kconfig index 0cb92d651ff1..7ca7e1dab52c 100644 --- a/drivers/gpu/drm/exynos/Kconfig +++ b/drivers/gpu/drm/exynos/Kconfig @@ -7,6 +7,7 @@ config DRM_EXYNOS select DRM_DISPLAY_HELPER if DRM_EXYNOS_DP select DRM_KMS_HELPER select VIDEOMODE_HELPERS + select FB_IO_HELPERS if DRM_FBDEV_EMULATION select SND_SOC_HDMI_CODEC if SND_SOC help Choose this option if you have a Samsung SoC Exynos chipset. diff --git a/drivers/gpu/drm/exynos/exynos_drm_fbdev.c b/drivers/gpu/drm/exynos/exynos_drm_fbdev.c index ea4b3d248aac..fdf65587f1fe 100644 --- a/drivers/gpu/drm/exynos/exynos_drm_fbdev.c +++ b/drivers/gpu/drm/exynos/exynos_drm_fbdev.c @@ -8,6 +8,8 @@ * Seung-Woo Kim */ +#include + #include #include #include @@ -47,13 +49,10 @@ static void exynos_drm_fb_destroy(struct fb_info *info) static const struct fb_ops exynos_drm_fb_ops = { .owner = THIS_MODULE, + __FB_DEFAULT_IO_OPS_RDWR, DRM_FB_HELPER_DEFAULT_OPS, + __FB_DEFAULT_IO_OPS_DRAW, .fb_mmap = exynos_drm_fb_mmap, - .fb_read = drm_fb_helper_cfb_read, - .fb_write = drm_fb_helper_cfb_write, - .fb_fillrect = drm_fb_helper_cfb_fillrect, - .fb_copyarea = drm_fb_helper_cfb_copyarea, - .fb_imageblit = drm_fb_helper_cfb_imageblit, .fb_destroy = exynos_drm_fb_destroy, };
