drm: move drm_can_sleep() to drm_util.h

2019-01-14T09:58:37Z

Move drm_can_sleep() out of drmP.h to allow users to get rid of the drmP.h include. There was no header file that was a good match for this helper function. So add this to drm_util with the relevant includes. Add include of drm_util.h to all users. v2: - Update comments to use kernel-doc style (Daniel) - Add FIXME to drm_can_sleep and add note that this function should not be used in new code (Daniel) v3: - Fix kernel-doc syntax (Daniel) - Plug drm_util.h into drm-internels.rst (Daniel) Signed-off-by: Sam Ravnborg Cc: Maarten Lankhorst Cc: Maxime Ripard Cc: Sean Paul Cc: David Airlie Cc: Daniel Vetter Cc: Alex Deucher Cc: "Christian König" Cc: "David (ChunMing) Zhou" Cc: Gerd Hoffmann Cc: Rob Clark Cc: Tomi Valkeinen Cc: Eric Anholt Signed-off-by: Daniel Vetter Link: https://patchwork.freedesktop.org/patch/msgid/20190112193251.20450-2-sam@ravnborg.org

drm/omap: Replace drm_gem_object_unreference_unlocked with put function

2018-10-02T06:36:56Z

This patch unifies the naming of DRM functions for reference counting of struct drm_gem_object. The resulting code is more aligned with the rest of the Linux kernel interfaces. Signed-off-by: Thomas Zimmermann Signed-off-by: Tomi Valkeinen

drm/omap: Group CRTC, encoder, connector and dssdev in a structure

2018-09-03T13:13:27Z

Create an omap_drm_pipeline structure to model display pipelines, made of a CRTC, an encoder, a connector and a DSS display device. This allows grouping related parameters together instead of storing them in independent arrays and thus improves code readability.

drm/omap: gem: Replace struct_mutex usage with omap_obj private lock

2018-06-28T10:41:05Z

The DRM device struct_mutex is used to protect against concurrent GEM object operations that deal with memory allocation and pinning. All those operations are local to a GEM object and don't need to be serialized across different GEM objects. Replace the struct_mutex with a local omap_obj.lock or drop it altogether where not needed. Signed-off-by: Laurent Pinchart Reviewed-by: Tomi Valkeinen Signed-off-by: Tomi Valkeinen

drm/omap: Init fbdev emulation only when we have displays

2018-03-01T07:18:18Z

Do not try to init the fbdev if either num_crtcs or num_connectors is 0. In this case we do not have display so the fbdev init would fail anyways. Signed-off-by: Peter Ujfalusi Signed-off-by: Tomi Valkeinen Reviewed-by: Laurent Pinchart

drm/omap: cleanup fbdev init/free

2018-03-01T07:18:18Z

omap_fbdev_init() and omap_fbdev_free() use priv->fbdev directly. However, omap_fbdev_init() returns the fbdev, and omap_drv.c also assigns the return value to priv->fbdev. This is slightly confusing. Clean this up by removing the omap_fbdev_init() return value, as we don't care whether fbdev init succeeded or not. Also change omap_drv.c to call omap_fbdev_free() always, and omap_fbdev_free() does the check if fbdev was initialized. While at it, rename omap_fbdev_free() to omap_fbdev_fini() to better match the "init" counterpart. Signed-off-by: Tomi Valkeinen Reviewed-by: Laurent Pinchart

drm/omap: fix omap_fbdev_free() when omap_fbdev_create() wasn't called

2018-03-01T07:18:18Z

If we have no crtcs/connectors, fbdev init goes fine, but omap_fbdev_create() is never called. This means that omap_fbdev->bo is NULL and omap_fbdev_free() crashes. Add a check to omap_fbdev_free() to handle the NULL case. Signed-off-by: Tomi Valkeinen Reviewed-by: Laurent Pinchart

drm: omapdrm: Remove filename from header and fix copyright tag

2017-12-19T09:21:32Z

Having the filename in the header serves little purpose and is often wrong after renames as it is here in several places, just drop it from all omapdrm files. While we are here unify the copyright tags to the TI recommended style. Signed-off-by: Andrew F. Davis
