* don't call hwc with non-empty layer lists for blanked displaysMathias Agopian2012-09-122-17/+20
| | | | | | | | | | | | we now make sure to take the blanked state of a display into account when we build its list of visible layers, this ensures that we won't call prepare/set with a non-empty list when the display is blanked. Possibly fixes 7075380, 7103553, 7130187, 7016215 Bug: 7075380 Change-Id: I9fdd2e73d1b7621eaeca3d4ac2ae60d9fb1b3631

* Reshuffle FramebufferSurfaceAndy McFadden2012-09-116-158/+202
| | | | | | | | | | FramebufferSurface no longer speaks directly to the FB HAL. Now everything goes through HWComposer (which may or may not be connected to a hardware composer). Added display index arg to some query methods. Change-Id: Id3e157d2d4e3555d33afbb703e518b6e92e2d6d5
* SurfaceTexture: use eglWaitSyncJamie Gennis2012-09-101-5/+3
| | | | | | | | | | | This change adds a compile-option to use eglWaitSyncANDROID to ensure that texturing operations that access the current buffer of a SurfaceTexture do not occur until the buffer is completely written. It also moves this synchronization into a new SurfaceTexture method called doGLFenceWait and changes SurfaceFlinger's Layer class to use that method rather than performing its own wait on the fence.

* Ensure that viewport and frame are initialized.Jeff Brown2012-09-092-1/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | onInitializeDisplays() was posting a transaction with changes to the display projection. Unfortunately, it only set the display orientation field and left viewport and frame uninitialized. The uninitialized values flowed downstream and found themselves baked into a bogus DisplayDevice mGlobalTransform. That transform was then applied to some Rects which were turned into Regions that were them combined with other Regions. Under certain situations, the uninitialized data might have a largish value, resulting in the creation of Regions with components in excess of the Region max-value limit of 0x7ffffff (note that this is not INT_MAX). Later when performing a binary operation using the Region, the Spanner would loop indefinitely trying to figure out how to stuff a humongous region inside of a max-value region. Not content to try just once, the Spanner would continue trying again and again, pegging the CPU and hanging surface flinger during boot. Insanity soon followed.

* libgui: move fence handling into ConsumerBaseJamie Gennis2012-09-061-1/+1
| | | | | | | | This change moves some common fence handling code into the base class for BufferQueue consumer classes. It also makes the ConsumerBase class initialize a buffer slot's fence with the acquire fence every time a buffer is acquired. Change-Id: I0bd88bc269e919653b659bfb3ebfb04dd61692a0
* fix a problem where all hwc layers would have the SKIP flags setMathias Agopian2012-09-052-1/+1
| | | | | | | | | the problem was that LayerBase::setPerFrameData() was always setting this flag. in fact there was no reason to do this at that point since the layer is initialized to a default state in setGeometry(). Bug: 7111259 Change-Id: Ib37b0dd7391a6163070e9aca025512159c1705f9

| * Always reset layer acquireFenceFd after commitJesse Hall2012-09-051-0/+2
| | | | | | | | | | | | | | | | | | | | If SurfaceFlinger needs to refresh the screen but the dirty region is empty, it won't set the layer acquire fences, and stale file descriptors will be passed to HWC commit(). Now we make sure to clear the stale file descriptors for each layer right after commit(). Bug: 7078301 Change-Id: I6953ff91fc5488f105b30b07306f9c45a4c3f780

* | the visible region sent to HWC was garbageMathias Agopian2012-08-315-5/+31
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | we used to have a visibleRegion object per layer, but now it's per screen; so at somepoint the code got changed to calculate the per-screen visible region on the stack and that's what got passed to HWC. we're now setting the visibleRegionScreen at each frame and freeing at after the HWC set() call. We use the underlaying SharedBuffer so that in most cases we don't have to allocate, free or copy memory around. Bug: 7089478 Change-Id: I24fa556c76613a225d9fe7a6c6b727bb476144d8

* Banish DisplayID from the SurfaceFlinger API.Jeff Brown2012-08-278-37/+42
| | | | | | | | | | | | | | | Use only display tokens in the API to refer to new displays. Don't require the caller to specify the display when creating a surface (since in general a surface could be shown on any display). This is intended to be a minimum change just to update the API. Note that SurfaceFlinger still uses DisplayID in a few places internally that might cause some features not to work properly when there are multiple displays (LayerScreenshot, for example).
