Provide an initializer macro for struct drm_driver that sets the callback according to the kernel configuration. Call drm_client_setup() to run the kernel's default client setup for DRM. Set fbdev_probe in struct drm_driver, so that the client setup can start the common fbdev client. The radeon driver specifies a preferred color mode depending on the available video memory, with a default of 32. Adapt this for the new client interface. v2: - style changes Signed-off-by: Thomas Zimmermann Cc: Alex Deucher Cc: "Christian König" Cc: Xinhui Pan Acked-by: Alex Deucher --- drivers/gpu/drm/radeon/radeon_drv.c | 14 +++- drivers/gpu/drm/radeon/radeon_fbdev.c | 114 ++------------------------ drivers/gpu/drm/radeon/radeon_mode.h | 12 ++- 3 files changed, 27 insertions(+), 113 deletions(-) diff --git a/drivers/gpu/drm/radeon/radeon_drv.c b/drivers/gpu/drm/radeon/radeon_drv.c index f36aa71c57c7..eae79f02d254 100644 --- a/drivers/gpu/drm/radeon/radeon_drv.c +++ b/drivers/gpu/drm/radeon/radeon_drv.c @@ -38,8 +38,10 @@ #include #include +#include #include #include +#include #include #include #include @@ -261,6 +263,7 @@ static int radeon_pci_probe(struct pci_dev *pdev, unsigned long flags = 0;
