Thers are 1-7 patches on this series. The kernel patches are targetted for support of memory allocation during boot time for large buffers. This will allow the user to get contiguous buffers beyond linux memory and can configure the location and size of the buffer using parametrs configured during boot time using bootargs. The current implementation will allow the application to get MMAP buffers but those buffers cannot be contiguous and create defragmentation. The approach to provide contiguous buffers is inherited from the ../drivers/media/video/sh_mobile_ceu_camera.c already exist in the community code which uses dma_alloc_coherent function to get the contiguous buffers from the memory. During runtime the driver will allocate the required buffers from the contiguous memory. The memory can be configured using the following arguments on the bootargs 1. Davinci display and vpfe cature driver davinci_display.cont2_bufsize=<size of the total display buffers in bytes> davinci_display.cont2_bufoffset=<offset for the display buffers from linux memory in bytes> vpfe_capture.cont_bufsize==<size of the total capture buffers in bytes> vpfe_capture.cont_bufoffset==<offset for the capture buffer from linux memory bytes> 2. DavinciHD VPIF display and capture driver vpif_display.cont_bufsize=<size of the display buffers in bytes> vpif_display.cont_bufoffset=<offset for the display buffers from linux memory in bytes> vpif_capture.cont_bufsize=<size of the capture buffers in bytes> vpif_capture.cont_bufoffset=<offset for the capture buffers from linux memory in bytes> The patches will be applied to the davinci tree the ../drivers/media/video/davinci and will affect the both the capture and display drivers. Apply these patches to the git kernel. -- To unsubscribe from this list: send the line "unsubscribe linux-media" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
