Hi all, I am facing a strange problem with in implementing kaaMoveInPixmap's UploadToScreen function to use acceleration for copying the src pixmap.In my scenario I am using a graphics card which uses buffers for copying. My SGA(smart graphics accelerator) card has input buffer and output buffer.These buffers have to be given the physical address of the buffer to copy from src(input buffer) to dst(output buffer). My output buffer is offscreen buffer which I have allocated in the kernel and passed the physical address to the kdrive driver.And then I can copy it onto onscreen using SGA.So first I have to bring the pixmap to offscreen area for copy operation to take place.But in case of kaaMoveInPixmap which moves the pixmap to offscreen if it is not offscreen I cannot copy using SGA.This is because the src pixmap address is a user space address for which I cannot obtain the corresponding physical address to give it to the SGA though I have the dst physical address i.e. framebuffer physical address.Thus I have to fallback to default memcpy.This will really degrade performance in case of Xvideo interface which I have to provide so that I can render using SGA since I have to call kaaMoveInPixmap to get the src pixmap to offscreen and even in implementing copy operation of kdrive. Is there a workaround to this?Can I somehow obtain the physical address corresponding to the non offscreen pixmap.Maybe by hacking X server code and allocating memory through kernel and passing on the physical address to user space.But I am not sure.Please Help. Thanks.
