620685c2e684082c82657732d1e35cefd0c79006 19-Oct-2012 Andy McFadden <fadden@android.com> Fix emulator vsync

The code that reserves display IDs was only run when a hardware
composer was present. The eventControl() function, which handles
enabling of vsync, was ignoring the request because the primary
display didn't appear in its set of allocated IDs. This moves
reservation of IDs for built-in displays outside the HWC-only block.

Also, added a couple of warnings in eventControl().

Two issues:

(1) We were announcing the hotplug event before we were ready to
handle blank/unblank events, so we were losing the initial unblank
that power manager sends us when HDMI is first plugged in. This
left the display blank until you toggled the device power off/on.

(2) We were retaining fbTargetHandle for HDMI after the display was
disconnected. The value didn't get updated when HDMI was reconnected
because the display was blank, so we didn't go through that code
path. So, when HDMI was re-connected, we passed stale data into
the HWC.

27ec5739bc05330e08b02f25b62a8f597bad897a 03-Oct-2012 Andy McFadden <fadden@android.com> Fix crashes after HDMI disconnect

The display was being removed from SurfaceFlinger's list before we
had a chance to reset HWComposer's layer list, so we were passing
stale data into the hardware composer (which has its own per-display
data). This resulted in "invalid gralloc handle" complaints.
We now clear the layer list immediately after removing the display.

The display was being removed while its EGLSurface was still
"current", resulting in "cancelBuffer: BufferQueue has been
abandoned" complaints. We now call makeCurrent on the primary
display before removing the external display.

This change makes SurfaceFlinger reset the acquire fence fd to -1 after each
call to HWComposer::commit. The HWComposer implementation is resonsible for
closing the fd, so SurfaceFlinger should make sure not to pass it to HWC
multiple times.

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.

Commit 8630320 moved the eglSwapBuffers fallback (for devices with no
HWC implementation) from DisplayHardware to HWComposer. But HWComposer
only knows about the framebuffer EGL display and surface handles if
there is a HWC, so it was always passing bogus handles.

This change moves the eglSwapBuffers fallback up to SurfaceFlinger,
which has access to the framebuffer EGL handles.

we will only ever have a single instance of HWComposer, so
it's now an attribute of SurfaceFlinger, instead of being part
of DisplayHardware.

DisplayHardware now just represents a "display" (it should be renamed).

Call into the new HWC blank operation to blank or unblank the screen.
Legacy systems may have already blanked the screen via early suspend,

After a HWC set, each SurfaceFlinger Layer retrieves the release fence
HWC returned and gives it to the layer's SurfaceTexture. The
SurfaceTexture accumulates the fences into a merged fence until the
next updateTexImage, then passes the merged fence to the BufferQueue
in releaseBuffer.

In a follow-on change, BufferQueue will return the fence along with
the buffer slot in dequeueBuffer. For now, dequeueBuffer waits for the
fence to signal before returning.

The releaseFence default value for BufferQueue::releaseBuffer() is
temporary to avoid transient build breaks with a multi-project
checkin. It'll disappear in the next change.

HWComposer must abstract the HWC HAL entirely, so that the
HAL can continue to evolve (and break binary compatibility)
without breaking SurfaceFlinger. The HWC data structure had
leaked outside of HWComposer, this is now fixed.

We now have an abstract interface that provide all the
needed functionality, HWCompose provides concrete
implementations of it based on the the HWC version.

128 lines of tab separated timestamps in nanosecond.

The first line currently contains the refresh period in nanosecond.
Each 128 following line contains 3 timestamps, of respectively
the app draw time, the vsync timestamp just prior the call to set and
the timestamp of the call to set.

6163091a2c366f8311fc3ee627dc7deb9681236e 07-Jul-2011 Mathias Agopian <mathias@google.com> Fix EGLUtils::selectConfigForPixelFormat()

- renderscript now calls EGL directly instead of relying on this function
- surfaceflinger also does its own EGLConfig selection
- selectConfigForPixelFormat stays for legacy reason (many tests use it) but
it now only tries to match the alpha channel of the format rather than the
format itself.

this will allow implementations who don't support the exact formats
defined in the HAL to work properly.

There are 16 events logged in the event log:
SF_APP_DEQUEUE_BEFORE
SF_APP_DEQUEUE_AFTER
SF_APP_LOCK_BEFORE
SF_APP_LOCK_AFTER
SF_APP_QUEUE

SF_REPAINT
SF_COMPOSITION_COMPLETE
SF_UNLOCK_CLIENTS
SF_SWAP_BUFFERS
SF_REPAINT_DONE

SF_FB_POST_BEFORE
SF_FB_POST_AFTER
SF_FB_DEQUEUE_BEFORE
SF_FB_DEQUEUE_AFTER
SF_FB_LOCK_BEFORE
SF_FB_LOCK_AFTER

all events log the buffer conserned and a timestamp in microseconds.

by default the logging is not enabled, to turn it on:
adb shell service call SurfaceFlinger 1006 i31 1
adb shell setprop debug.graphic_log 1

The effect is immediate in SurfaceFlinger, but applications need to be
restarted.
