[Mesa-dev] [RFC 0/6] VK_ANDROID_external_memory_android_hardware_buffer

[Tapani Pälli]

Hi;

Here's RFC for the extension. I've tested the import/export functionality
with RGBA images on Android Celadon with a custom NDK app that draws a 
textured cube using AHardwareBuffer contents. Export feature I tested
by creating just a regular image (LunarG cube texture) and then exporting
that as AHardwareBuffer, modifying buffer and then rendering the
results.

I wanted to send this RFC to get some comments on what's missing and if
I have understood the specification correctly. If supporting only RGBA
for now is fine, I believe we could go forward with these bits.

Any comments appreciated!

Thanks;
