From 6ebf23bf5ea3ba541cced9d7dee782c62f613f9b Mon Sep 17 00:00:00 2001 From: Thomas Zimmermann Date: Tue, 30 May 2023 17:12:21 +0200 Subject: [PATCH] drm/radeon: Use regular fbdev I/O helpers MIME-Version: 1.0 Content-Type: text/plain; charset=utf8 Content-Transfer-Encoding: 8bit Use the regular fbdev helpers for framebuffer I/O instead of DRM's helpers. Radeon 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 v2: * use FB_IO_HELPERS option Signed-off-by: Thomas Zimmermann Acked-by: Alex Deucher Acked-by: Sam Ravnborg Cc: Alex Deucher Cc: "Christian König" Cc: "Pan, Xinhui" Link: https://patchwork.freedesktop.org/patch/msgid/20230530151228.22979-7-tzimmermann@suse.de --- drivers/gpu/drm/radeon/Kconfig | 1 + drivers/gpu/drm/radeon/radeon_fbdev.c | 9 +++------ 2 files changed, 4 insertions(+), 6 deletions(-) diff --git a/drivers/gpu/drm/radeon/Kconfig b/drivers/gpu/drm/radeon/Kconfig index e19d77d..fe498c8 100644 --- a/drivers/gpu/drm/radeon/Kconfig +++ b/drivers/gpu/drm/radeon/Kconfig @@ -11,6 +11,7 @@ config DRM_RADEON select DRM_SUBALLOC_HELPER select DRM_TTM select DRM_TTM_HELPER + select FB_IO_HELPERS if DRM_FBDEV_EMULATION select SND_HDA_COMPONENT if SND_HDA_CORE select POWER_SUPPLY select HWMON diff --git a/drivers/gpu/drm/radeon/radeon_fbdev.c b/drivers/gpu/drm/radeon/radeon_fbdev.c index fe76e29..28212c2 100644 --- a/drivers/gpu/drm/radeon/radeon_fbdev.c +++ b/drivers/gpu/drm/radeon/radeon_fbdev.c @@ -24,6 +24,7 @@ * David Airlie */ +#include #include #include #include @@ -190,14 +191,10 @@ static void radeon_fbdev_fb_destroy(struct fb_info *info) static const struct fb_ops radeon_fbdev_fb_ops = { .owner = THIS_MODULE, - DRM_FB_HELPER_DEFAULT_OPS, .fb_open = radeon_fbdev_fb_open, .fb_release = radeon_fbdev_fb_release, - .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_DEFAULT_IO_OPS, + DRM_FB_HELPER_DEFAULT_OPS, .fb_destroy = radeon_fbdev_fb_destroy, }; -- 2.7.4
