mind to tell us, how do you allocate memory? kmalloc?
Via kmalloc.
Please use the functions written to give you large memory chunks. As you are using a video-for-linux device, why not use the apis that this framework provides you for this type of thing?
Yes V4L would be done next. There are some things being tried out, this being a custom FPGA hence some controls being experimented. As for the allocating in PAGE_SIZE chunks why am I running out of memory? Can't it steal smaller chunks from the larger chunks? Just curious about the reason.
