[Matt Brubeck (:mbrubeck)]

After I set layers.accelerate-all to "true" on my T-Mobile G2, about:support still says "GPU Accelerated Windows: 0/1"

After restarting?

Comment 2

[Matt Brubeck (:mbrubeck)]

Yes.

Comment 3

[Matt Brubeck (:mbrubeck)]

During startup I see "I/Gecko   ( 1885): Failed to create EGL config!"

Comment 4

[Benoit Girard (:BenWa)]

Have you tried setting the following:
+pref("layers.acceleration.disabled", false);
+pref("layers.acceleration.force-enabled", true);

With these prefs set in the latest mozilla-central nightly on T-Mobile G2, about:support says:

Adapter Description: Android T-Mobile G2 HTC vision
WebGL Renderer: Qualcomm -- Adreno 205 -- OpenGL ES 2.0 1309647
GPU Accelerated Windows: 0/1. Blocked for your graphics card because of unresolved driver issues.

Will set this issue aside until the major fixes for opengl have been landed on m-c.

Comment 7

[Benoit Girard (:BenWa)]

Can you give us a list of supported EGL configurations for your phone? I have some time to look into this.

You can use the app 'Quadrant Standard' from the app market. Select 'System information' from the main menu. Under the 'GPU (OpenGL)' heading (far below it) you will find 'Pixel formats (x)'. Nexus S looks a bit like this:
rgba: 5650 z:0 stencil: 0
rgba: 5650 z:16 stencil: 0
etc...

From Quadrant Standard Edition:

Pixel formats (10):
rgba: 5650 z: 0 stencil: 0
rgba: 5650 z: 16 stencil: 0
rgba: 5650 z: 24 stencil: 8
rgba: 8880 z: 0 stencil: 0
rgba: 8880 z: 16 stencil: 0
rgba: 8888 z: 0 stencil: 0
rgba: 8888 z: 16 stencil: 0
rgba: 8888 z: 24 stencil: 8
rgba: 0008 z: 0 stencil: 0
rgba: 0008 z: 16 stencil: 0

Comment 9

[Benoit Girard (:BenWa)]

The function is failing because we fail to find a config that meets the following. It has OPENGL_ES2 and also supports 565 (Comment 8). This will need to be looked at with a debugger. Thanks Matt.

LOCAL_EGL_SURFACE_TYPE,    LOCAL_EGL_WINDOW_BIT,
LOCAL_EGL_RENDERABLE_TYPE, LOCAL_EGL_OPENGL_ES2_BIT,
LOCAL_EGL_RED_SIZE,        5,
LOCAL_EGL_GREEN_SIZE,      6,
LOCAL_EGL_BLUE_SIZE,       5,
LOCAL_EGL_ALPHA_SIZE,      0,
LOCAL_EGL_NONE

George is going to see if he can reproduce this.

Matt - can you reproduce this with http://people.mozilla.org/~gwright/files/fennec-12.0a1.en-US.android-arm.apk

With that build on my G2, I get "GPU Accelerated Windows: 1/1 OpenGL"

Comment 13

[George Wright (:gw280) (needinfo me!)]

OK, seems like this has been fixed then, as that build is just a vanilla build of mozilla-central with one small change I made which is unrelated to this.
