PSDKLA 3.00 on Jacinto-6 :: Not able to initialize EGL with "EGL_PIXMAP_BIT" frame buffer configuration

Jeyaprabu Jeyakumar

Hi,

EVM: Jacinto-6 running on PSDKLA 3.00

I am trying to initialize EGL. I am trying to use frame buffer configuration of type "EGL_PIXMAP_BIT ".

But on PSDKLA 3.00, there seems to be no such frame buffer configuration available for frame buffer type "EGL_PIXMAP_BIT", but available on GLSDK 7.04 (Checked with eglGetConfigAttrib).

All frame buffer types available on PSDKLA 3.00 are of type "EGL_WINDOW_BIT" (Checked with eglGetConfigAttrib).

How to use frame buffer type "EGL_PIXMAP_BIT " on PSDKLA 3.00 ?

Thanks,

Jeyaprabu.

Hi,

Can you let us know your use case? The pixmap bit is typically used when you need offscreen surfaces.

The relevant portions are undergoing changes in 3.00 release compared to 7.04. We want to make sure your feature is covered.

Anand

Hi Anand,

Yes we need offscreen surfaces. We want to use pixmap for our application.

Can we implement it in PSDKLA 3.00 ?

Hi Jeyaprabu,

This feature is under development and should be available by end-Oct.

Which EGL backend are you using? GBM?

Anand

Hi Anand,

Yes we are using GBM.

The great resemblance of our application is sample eglPixmap Application from you.

Hi Jeyaprabu,

Thanks for confirming. If you are using the GFX sample application we had provided, it should be fine.

This feature is getting reviewed and will be published by end-Oct. In addition, we are also adding a feature to import a DMABUF as GBM pixmap. In our earlier implementation, it was not straightforward to access the underlying DMABUF for a pixmap. Thushara had questions on this front earlier.

With the new model, you can create a DMABUF and import it as a GBM pixmap or an EGLImage. This way, application can maintain correlation between the DRM buffer and higher level EGL layers.

Anand

Hi Anand,

We need to know whether the features(pixmap) under development are ready in PSDKLA 3.0.

Hi Jeyaprabu,

The EGLImage import of DMABUF feature was published on 25-Oct:
git.ti.com/.../fccafce7d0a023e36c064ccbaa7d33e89252ea00

The GBM pixmap feature is under review and will be published by mid-Dec timeframe.

Hi Anand,

Is support for PIXMAP added in PSDKLA. If not when can it be expected?

We checked that the support for PIXMAP is not included in PSDKLA 3.01.00.03, using EGL PIXMAP application available at

Hi Jeyaprabu,

The support is being formally added to PSDKLA 3.02 release which will be available by end of next week.
