2015-11-24drm: Pass the user drm_mode_fb_cmd2 as const to .fb_create()Ville Syrjälä1-1/+1
Drivers shouldn't clobber the passed in addfb ioctl parameters. i915 was doing just that. To prevent it from happening again, pass the struct around as const, starting all the way from internal_framebuffer_create().

2015-10-07drm: Stop using drm_vblank_count() as the hw frame counterVille Syrjälä1-1/+1
drm_vblank_count() returns the software counter. We should not pretend it's the hw counter since we use the hw counter to figuere out what the software counter value should be. So instead provide a new function drm_vblank_no_hw_counter() for drivers that don't have a real hw counter. The new function simply returns 0, which is about the only thing it can do.

2015-10-06drm/irq: Use unsigned int pipe in public APIThierry Reding1-2/+4
This continues the pattern started in commit cc1ef118fc09 ("drm/irq: Make pipe unsigned and name consistent"). This is applied to the public APIs and driver callbacks, so pretty much all drivers need to be updated to match the new prototypes.

2015-09-08drm/atomic: Make prepare_fb/cleanup_fb only take state, v3.Maarten Lankhorst1-1/+3
This removes the need to separately track fb changes i915. That will be done as a separate commit, however. Changes since v1: - Add dri-devel to cc. - Fix a check in intel's prepare and cleanup fb to take rotation into account. Changes since v2: - Split out i915 changes to a separate commit.

2015-07-27drm/atomic: pass old crtc state to atomic_begin/flush.Maarten Lankhorst1-2/+4

Unfortunately we used the enabled flag in struct drm_crtc instead of the enabled flag in struct atmel_hlcdc_crtc. This obviously leads to discrepancies on crtc enable state.

2015-03-05drm: Pass in new and old plane state to prepare_fb and cleanup_fbTvrtko Ursulin1-1/+2
Use cases like rotation require these hooks to have some context so they know how to prepare and cleanup the frame buffer correctly. For i915 specifically, object backing pages need to be mapped differently for different rotation modes and the driver needs to know which mapping to instantiate and which to tear down when transitioning between them. v2: Made passed in states const.

2015-02-24drm: atmel-hlcdc: reset layer A2Q and UPDATE bits when disabling itBoris Brezillon1-1/+2
The A2Q (Add To Queue) and UPDATE bits are left in their previous state when resetting the layer. This lead to weird behavior when enabling the plane again: the framebuffer previously queued is dequeued and we end up with access to an old memory region. Reset those bits when resetting the channel. Signed-off-by: Boris Brezillon <[email protected]>

2015-02-22drm: atmel-hlcdc: add discard area supportBoris Brezillon3-1/+111
The HLCDC IP provides a way to discard a specific area on the primary plane (in case at least one of the overlay is activated and alpha blending is disabled). Doing this will reduce the amount of data to transfer from the main memory to the Display Controller, and thus alleviate the load on the memory bus (since this link is quite limited on such hardware, this kind of optimization is really important).

2015-01-21drm: add Atmel HLCDC Display Controller supportBoris Brezillon9-0/+3456
The Atmel HLCDC (HLCD Controller) IP available on some Atmel SoCs (i.e. at91sam9n12, at91sam9x5 family or sama5d3 family) provides a display controller device. This display controller supports at least one primary plane and might provide several overlays and an hardware cursor depending on the IP version. At the moment, this driver only implements an RGB connector to interface with LCD panels, but support for other kind of external devices might be added later.
