From 5f58e9742df3f1cdf1034a26569649f5f4fd776b Mon Sep 17 00:00:00 2001 From: Daniel Vetter Date: Mon, 26 Jun 2017 18:19:48 +0200 Subject: [PATCH] drm/vmwgfx: Drop drm_vblank_cleanup Again stopping the vblank before uninstalling the irq handler is kinda the wrong way round, but the fb_off stuff should take care of disabling the dsiplay at least in most cases. So drop the drm_vblank_cleanup code since it's not really doing anything, it looks all cargo-culted. v2: Appease gcc better. v3: Simplify code (Sean Paul) Cc: Sinclair Yeh Cc: Thomas Hellstrom Reviewed-by: Sean Paul Reviewed-by: Thomas Hellstrom Signed-off-by: Daniel Vetter Link: http://patchwork.freedesktop.org/patch/msgid/20170626161949.25629-1-daniel.vetter@ffwll.ch --- drivers/gpu/drm/vmwgfx/vmwgfx_kms.c | 8 ++------ drivers/gpu/drm/vmwgfx/vmwgfx_kms.h | 2 -- drivers/gpu/drm/vmwgfx/vmwgfx_ldu.c | 4 ---- drivers/gpu/drm/vmwgfx/vmwgfx_scrn.c | 9 --------- drivers/gpu/drm/vmwgfx/vmwgfx_stdu.c | 27 +-------------------------- 5 files changed, 3 insertions(+), 47 deletions(-) diff --git a/drivers/gpu/drm/vmwgfx/vmwgfx_kms.c b/drivers/gpu/drm/vmwgfx/vmwgfx_kms.c index a8876b070168..5fab9edf359c 100644 --- a/drivers/gpu/drm/vmwgfx/vmwgfx_kms.c +++ b/drivers/gpu/drm/vmwgfx/vmwgfx_kms.c @@ -1771,7 +1771,7 @@ int vmw_kms_init(struct vmw_private *dev_priv) int vmw_kms_close(struct vmw_private *dev_priv) { - int ret; + int ret = 0; /* * Docs says we should take the lock before calling this function @@ -1779,11 +1779,7 @@ int vmw_kms_close(struct vmw_private *dev_priv) * drm_encoder_cleanup which takes the lock we deadlock. */ drm_mode_config_cleanup(dev_priv->dev); - if (dev_priv->active_display_unit == vmw_du_screen_object) - ret = vmw_kms_sou_close_display(dev_priv); - else if (dev_priv->active_display_unit == vmw_du_screen_target) - ret = vmw_kms_stdu_close_display(dev_priv); - else + if (dev_priv->active_display_unit == vmw_du_legacy) ret = vmw_kms_ldu_close_display(dev_priv); return ret; diff --git a/drivers/gpu/drm/vmwgfx/vmwgfx_kms.h b/drivers/gpu/drm/vmwgfx/vmwgfx_kms.h index 13f2f1d2818a..f94b4ca38ab2 100644 --- a/drivers/gpu/drm/vmwgfx/vmwgfx_kms.h +++ b/drivers/gpu/drm/vmwgfx/vmwgfx_kms.h @@ -405,7 +405,6 @@ int vmw_kms_update_proxy(struct vmw_resource *res, * Screen Objects display functions - vmwgfx_scrn.c */ int vmw_kms_sou_init_display(struct vmw_private *dev_priv); -int vmw_kms_sou_close_display(struct vmw_private *dev_priv); int vmw_kms_sou_do_surface_dirty(struct vmw_private *dev_priv, struct vmw_framebuffer *framebuffer, struct drm_clip_rect *clips, @@ -433,7 +432,6 @@ int vmw_kms_sou_readback(struct vmw_private *dev_priv, * Screen Target Display Unit functions - vmwgfx_stdu.c */ int vmw_kms_stdu_init_display(struct vmw_private *dev_priv); -int vmw_kms_stdu_close_display(struct vmw_private *dev_priv); int vmw_kms_stdu_surface_dirty(struct vmw_private *dev_priv, struct vmw_framebuffer *framebuffer, struct drm_clip_rect *clips, diff --git a/drivers/gpu/drm/vmwgfx/vmwgfx_ldu.c b/drivers/gpu/drm/vmwgfx/vmwgfx_ldu.c index d3987bcf53f8..449ed4fba0f2 100644 --- a/drivers/gpu/drm/vmwgfx/vmwgfx_ldu.c +++ b/drivers/gpu/drm/vmwgfx/vmwgfx_ldu.c @@ -582,13 +582,9 @@ err_free: int vmw_kms_ldu_close_display(struct vmw_private *dev_priv) { - struct drm_device *dev = dev_priv->dev; - if (!dev_priv->ldu_priv) return -ENOSYS; - drm_vblank_cleanup(dev); - BUG_ON(!list_empty(&dev_priv->ldu_priv->active)); kfree(dev_priv->ldu_priv); diff --git a/drivers/gpu/drm/vmwgfx/vmwgfx_scrn.c b/drivers/gpu/drm/vmwgfx/vmwgfx_scrn.c index 8d7dc9def7c2..3b917c9b0c21 100644 --- a/drivers/gpu/drm/vmwgfx/vmwgfx_scrn.c +++ b/drivers/gpu/drm/vmwgfx/vmwgfx_scrn.c @@ -746,15 +746,6 @@ int vmw_kms_sou_init_display(struct vmw_private *dev_priv) return 0; } -int vmw_kms_sou_close_display(struct vmw_private *dev_priv) -{ - struct drm_device *dev = dev_priv->dev; - - drm_vblank_cleanup(dev); - - return 0; -} - static int do_dmabuf_define_gmrfb(struct vmw_private *dev_priv, struct vmw_framebuffer *framebuffer) { diff --git a/drivers/gpu/drm/vmwgfx/vmwgfx_stdu.c b/drivers/gpu/drm/vmwgfx/vmwgfx_stdu.c index bad31bdf09b6..b4d4074c0ae0 100644 --- a/drivers/gpu/drm/vmwgfx/vmwgfx_stdu.c +++ b/drivers/gpu/drm/vmwgfx/vmwgfx_stdu.c @@ -1634,36 +1634,11 @@ int vmw_kms_stdu_init_display(struct vmw_private *dev_priv) if (unlikely(ret != 0)) { DRM_ERROR("Failed to initialize STDU %d", i); - goto err_vblank_cleanup; + return ret; } } DRM_INFO("Screen Target Display device initialized\n"); - return 0; - -err_vblank_cleanup: - drm_vblank_cleanup(dev); - return ret; -} - - - -/** - * vmw_kms_stdu_close_display - Cleans up after vmw_kms_stdu_init_display - * - * @dev_priv: VMW DRM device - * - * Frees up any resources allocated by vmw_kms_stdu_init_display - * - * RETURNS: - * 0 on success - */ -int vmw_kms_stdu_close_display(struct vmw_private *dev_priv) -{ - struct drm_device *dev = dev_priv->dev; - - drm_vblank_cleanup(dev); - return 0; } -- 2.20.1
