i try to develop some kind of a screen-grabber… for the SGX544MP GPU at android.
So i read every dokumentation i had found about this GPU and i looked at the kernel-driver for android (http://review.omapzoom.org/device/ti/proprietary-open).
But still a have some questions:
- Does SGX544MP devices use its own graphics memory ( in hardware ) or use it shared-memory ?
- When it use shared-memory, the GPU will not use some kind of direct memory access (DMA) for the transfer…it simple use some memory-mapping (which is faster,- i think)
- When both assumptions are correct, the current screen-data can found in the systen-memory. Which i can access from kerne-space to grab it.
Where can i find the curret source-lines in your driver ?
