Hello All, I'm pretty new to the OMAP DSS and would like to understand how it works under Linux/Android. I have read the TRM and understood that the DSS uses DMA to move pixels from the main memory to several hardware pipelines, with each burst of a few lines. But I am wondering - 1 - when will DSS start to move a new frame from the framebuffer to hardware pipelines? Is it triggered by some timer, or by some signals from the LCD panel (e.g., VSYNC)? 2 - is it possible to measure/estimate the time taken in DMAing a frame? I also looked into the kernel doc and source code but found no answer. I appreciate any comments or pointers. Thanks a lot! -Felix -- To unsubscribe from this list: send the line "unsubscribe linux-omap" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
