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 loongson driver specifies a preferred color mode of 32. As this is the default if no format has been given, leave it out entirely. v5: - select DRM_CLIENT_SELECTION Signed-off-by: Thomas Zimmermann <tzimmermann@xxxxxxx> Cc: Sui Jingfeng <suijingfeng@xxxxxxxxxxx> Acked-by: Sui Jingfeng <sui.jingfeng@xxxxxxxxx> --- drivers/gpu/drm/loongson/Kconfig | 1 + drivers/gpu/drm/loongson/lsdc_drv.c | 4 +++- 2 files changed, 4 insertions(+), 1 deletion(-) diff --git a/drivers/gpu/drm/loongson/Kconfig b/drivers/gpu/drm/loongson/Kconfig index 9ed463a76ae2..552edfec7afb 100644 --- a/drivers/gpu/drm/loongson/Kconfig +++ b/drivers/gpu/drm/loongson/Kconfig @@ -4,6 +4,7 @@ config DRM_LOONGSON tristate "DRM support for Loongson Graphics" depends on DRM && PCI && MMU depends on LOONGARCH || MIPS || COMPILE_TEST + select DRM_CLIENT_SELECTION select DRM_KMS_HELPER select DRM_TTM select DRM_TTM_HELPER diff --git a/drivers/gpu/drm/loongson/lsdc_drv.c b/drivers/gpu/drm/loongson/lsdc_drv.c index adc7344d2f80..a19dce35c839 100644 --- a/drivers/gpu/drm/loongson/lsdc_drv.c +++ b/drivers/gpu/drm/loongson/lsdc_drv.c @@ -9,6 +9,7 @@ #include <drm/drm_aperture.h> #include <drm/drm_atomic.h> #include <drm/drm_atomic_helper.h> +#include <drm/drm_client_setup.h> #include <drm/drm_drv.h> #include <drm/drm_fbdev_ttm.h> #include <drm/drm_gem_framebuffer_helper.h> @@ -47,6 +48,7 @@ static const struct drm_driver lsdc_drm_driver = { .dumb_create = lsdc_dumb_create, .dumb_map_offset = lsdc_dumb_map_offset, .gem_prime_import_sg_table = lsdc_prime_import_sg_table, + DRM_FBDEV_TTM_DRIVER_OPS, }; static const struct drm_mode_config_funcs lsdc_mode_config_funcs = { @@ -314,7 +316,7 @@ static int lsdc_pci_probe(struct pci_dev *pdev, const struct pci_device_id *ent) if (ret) return ret; - drm_fbdev_ttm_setup(ddev, 32); + drm_client_setup(ddev, NULL); return 0; } -- 2.46.0
