As I know,the application use V4L API to get the Capture Data from the CCDC,it
use the mmap() function.
And if you want to know more about this, please refer to
"drivers/media/video/davinci_vpfe.c" and "drivers/media/video/video-buf.c"
and please take attention to below functions
"vpfe_mmap(struct file *file, struct vm_area_struct *vma)"
"videobuf_mmap_mapper(struct videobuf_queue *q,struct vm_area_struct *vma)"
Hope it helps.

Hi all:
Does DVEVM DEMO use EDMA function? if it uses EDMA, where are the correlative
fils? I think it needs EMDA to transfer image capture data from CCDC shared
buffer logic(SBL) to DDR2, who has this experience, please give me a help,
thank you!
BESTREGARDS
