From 4020b220edb3419975c0d9322ee0e0c07e09f6bf Mon Sep 17 00:00:00 2001 From: Daniel Vetter Date: Thu, 28 Jan 2016 12:01:04 +0100 Subject: drm/vblank: Use drm_event_reserve_init Well we can't use that directly since that code must hold dev->event_lock already. Extract an _unlocked version. Embarrassingly I've totally forgotten about this patch and any kind of event-based vblank wait totally blew up, killing the kernel. v2: Pick the right base struct, someone didn't noticed that gcc was unhappy. No bug since the addresses at least matched (Daniel Stone) Cc: Alex Deucher Cc: Daniel Stone Cc: Laurent Pinchart Reviewed-by: Daniel Stone Signed-off-by: Daniel Vetter Link: http://patchwork.freedesktop.org/patch/msgid/1453978864-1513-1-git-send-email-daniel.vetter@ffwll.ch --- include/drm/drmP.h | 4 ++++ 1 file changed, 4 insertions(+) (limited to 'include/drm') diff --git a/include/drm/drmP.h b/include/drm/drmP.h index 306ef32ec086..1b71852d0a55 100644 --- a/include/drm/drmP.h +++ b/include/drm/drmP.h @@ -926,6 +926,10 @@ ssize_t drm_read(struct file *filp, char __user *buffer, int drm_release(struct inode *inode, struct file *filp); int drm_new_set_master(struct drm_device *dev, struct drm_file *fpriv); unsigned int drm_poll(struct file *filp, struct poll_table_struct *wait); +int drm_event_reserve_init_locked(struct drm_device *dev, + struct drm_file *file_priv, + struct drm_pending_event *p, + struct drm_event *e); int drm_event_reserve_init(struct drm_device *dev, struct drm_file *file_priv, struct drm_pending_event *p, -- cgit v1.2.3
