From 1199d01d0f291fc18e41da498412af7b23d01582 Mon Sep 17 00:00:00 2001 From: Thomas Zimmermann Date: Thu, 7 May 2020 11:03:13 +0200 Subject: [PATCH] drm/mgag200: Use managed mode-config initialization Mode configuration is now cleanued up automatically. While at it, move all mode-config code into mgag200_mode.c. Done in preparation of switching mgag200 to simple-KMS helpers. v2: * improve commit message (Sam) * rebased during cherry pick * also move bpp_shift initialization Signed-off-by: Thomas Zimmermann Acked-by: Sam Ravnborg Tested-by: John Donnelly Link: https://patchwork.freedesktop.org/patch/msgid/20200507090315.21274-5-tzimmermann@suse.de --- drivers/gpu/drm/mgag200/mgag200_drv.h | 1 - drivers/gpu/drm/mgag200/mgag200_main.c | 28 ++------------------- drivers/gpu/drm/mgag200/mgag200_mode.c | 34 ++++++++++++++++++++++---- 3 files changed, 31 insertions(+), 32 deletions(-) diff --git a/drivers/gpu/drm/mgag200/mgag200_drv.h b/drivers/gpu/drm/mgag200/mgag200_drv.h index 93e2d232931af..65d7096cad889 100644 --- a/drivers/gpu/drm/mgag200/mgag200_drv.h +++ b/drivers/gpu/drm/mgag200/mgag200_drv.h @@ -201,7 +201,6 @@ mgag200_flags_from_driver_data(kernel_ulong_t driver_data) /* mgag200_mode.c */ int mgag200_modeset_init(struct mga_device *mdev); -void mgag200_modeset_fini(struct mga_device *mdev); /* mgag200_main.c */ int mgag200_driver_load(struct drm_device *dev, unsigned long flags); diff --git a/drivers/gpu/drm/mgag200/mgag200_main.c b/drivers/gpu/drm/mgag200/mgag200_main.c index 186197b8ffd35..fd651eda6f012 100644 --- a/drivers/gpu/drm/mgag200/mgag200_main.c +++ b/drivers/gpu/drm/mgag200/mgag200_main.c @@ -10,15 +10,8 @@ #include -#include -#include - #include "mgag200_drv.h" -static const struct drm_mode_config_funcs mga_mode_funcs = { - .fb_create = drm_gem_fb_create -}; - static int mga_probe_vram(struct mga_device *mdev, void __iomem *mem) { int offset; @@ -135,27 +128,14 @@ int mgag200_driver_load(struct drm_device *dev, unsigned long flags) if (ret) return ret; - mdev->bpp_shifts[0] = 0; - mdev->bpp_shifts[1] = 1; - mdev->bpp_shifts[2] = 0; - mdev->bpp_shifts[3] = 2; - ret = mgag200_mm_init(mdev); if (ret) goto err_mm; - drm_mode_config_init(dev); - dev->mode_config.funcs = (void *)&mga_mode_funcs; - if (IS_G200_SE(mdev) && mdev->vram_fb_available < (2048*1024)) - dev->mode_config.preferred_depth = 16; - else - dev->mode_config.preferred_depth = 32; - dev->mode_config.prefer_shadow = 1; - ret = mgag200_modeset_init(mdev); if (ret) { drm_err(dev, "Fatal error during modeset init: %d\n", ret); - goto err_modeset; + goto err_mgag200_mm_fini; } ret = mgag200_cursor_init(mdev); @@ -164,9 +144,7 @@ int mgag200_driver_load(struct drm_device *dev, unsigned long flags) return 0; -err_modeset: - drm_mode_config_cleanup(dev); - mgag200_cursor_fini(mdev); +err_mgag200_mm_fini: mgag200_mm_fini(mdev); err_mm: dev->dev_private = NULL; @@ -179,8 +157,6 @@ void mgag200_driver_unload(struct drm_device *dev) if (mdev == NULL) return; - mgag200_modeset_fini(mdev); - drm_mode_config_cleanup(dev); mgag200_cursor_fini(mdev); mgag200_mm_fini(mdev); dev->dev_private = NULL; diff --git a/drivers/gpu/drm/mgag200/mgag200_mode.c b/drivers/gpu/drm/mgag200/mgag200_mode.c index aaa73b29b04f0..7dad386913261 100644 --- a/drivers/gpu/drm/mgag200/mgag200_mode.c +++ b/drivers/gpu/drm/mgag200/mgag200_mode.c @@ -13,6 +13,7 @@ #include #include +#include #include #include #include @@ -1615,6 +1616,17 @@ static struct drm_connector *mga_vga_init(struct drm_device *dev) return connector; } +static const struct drm_mode_config_funcs mgag200_mode_config_funcs = { + .fb_create = drm_gem_fb_create +}; + +static unsigned int mgag200_preferred_depth(struct mga_device *mdev) +{ + if (IS_G200_SE(mdev) && mdev->vram_fb_available < (2048*1024)) + return 16; + else + return 32; +} int mgag200_modeset_init(struct mga_device *mdev) { @@ -1623,13 +1635,30 @@ int mgag200_modeset_init(struct mga_device *mdev) struct drm_connector *connector; int ret; + mdev->bpp_shifts[0] = 0; + mdev->bpp_shifts[1] = 1; + mdev->bpp_shifts[2] = 0; + mdev->bpp_shifts[3] = 2; + + ret = drmm_mode_config_init(dev); + if (ret) { + drm_err(dev, "drmm_mode_config_init() failed, error %d\n", + ret); + return ret; + } + mdev->mode_info.mode_config_initialized = true; dev->mode_config.max_width = MGAG200_MAX_FB_WIDTH; dev->mode_config.max_height = MGAG200_MAX_FB_HEIGHT; + dev->mode_config.preferred_depth = mgag200_preferred_depth(mdev); + dev->mode_config.prefer_shadow = 1; + dev->mode_config.fb_base = mdev->mc.vram_base; + dev->mode_config.funcs = &mgag200_mode_config_funcs; + mga_crtc_init(mdev); ret = drm_simple_encoder_init(dev, encoder, DRM_MODE_ENCODER_DAC); @@ -1651,8 +1680,3 @@ int mgag200_modeset_init(struct mga_device *mdev) return 0; } - -void mgag200_modeset_fini(struct mga_device *mdev) -{ - -} -- 2.39.5
