i.MX6 Android BSP HWcomposer error.

[satoshishimoda]

Hi community,

I have a question about i.MX6DQ Android BSP (jb4.2.2_1.0.0).

Our partner tried to switching a screen from Android application, but it was failed with the following error which is output by /device/fsl-proprietary/gpu-viv/lib/hw/hwcomposer_viv.imx6.so.

Hi Karina Valencia Aguilar,

Unfortunately, I could not download the .so file even though I clicked the link with a "Unauthorized" message.

Could you send me it again?

Hi Michel,

We have two questions about the library you sent me.

Q1.

What is modified?

Q2.

Does Android 4.2.2_1.1.0 BSP include this library?

Clipping was added to make sure the coordinates were valid on the screen.

That change is included in jb4.3 and in the next release.

Hi Michel,

Thank you for your reply, but sorry I did not understand what is "clipping".

Could you kindly let me know what is it?

And what is "next release"?

Next release of android 4.2.2? or next release of jb4.3?

If it means next release of jb4.3, does the library work well on jb4.2 even though android version is not same?

Best Regards,

Clipping means that only the a valid rectangle is switched to the other screen, by "clipping" what is not valid.

The change will be available in jb4.3 and there should be no problem in using the SO provided in this thread since it comes from the same source three.

Just keep in mind the change hasn't been extensively tested, just unittested. It will be extensively tested in jb4.3.

Hi Michel,

I have another hwcomposer issue at below thread.

imx6DL dual display - hwcomposer_viv.imx6.so crash

My environment is 4.4.2 and upgrade to android_kk4.4.2_1.0.0-ga_core_source.tar.gz already.

This issue was gone after update your hwcomposer_viv.imx6.so.zip

Is any official release for this library? release note?

Where I can get newest release for 4.4.2?

Thanks.

Hi Michel,

Thank you, I could download it.

And please wait a little to test the library.
