gralloc module for Android

Hello,

I'm trying to compile the gralloc module released as opensource, but it cannot find the ump *userspace* headerfiles. I've looked in the kernel driver release, but this only includes the kernel headers for the UMP driver, not the userland headers.

Will the userland headers also be released or do I need to reverse-engineer those to be able to compile the released code?

Regards,

Ithamar.

Hi,

I think the files you're after were included in later driver releases.

HTH, Pete

The Gralloc module is used by Android's composition engine in order to allocate and manage memory which is suitable for 2D and 3D graphics usage. The Mali driver stack is able to use UMP memory directly, resulting in zero-copy operations when compositing.
