Hi ,
I have an use-case where i need to reserve high volume memory
buffer - (Video buffer) and it has to be shared between user-space and
kernel space. Please help me how to we achieve this using "/dev/pmem" device
?When registering platform device - PMEM device, we are supplying base address .And this memory is ioremap-ed under pmem driver . Please let me know how this memory is reserved ? Is it necessary to boot linux with param MEM , to define less memory ? -- With Regards, ShankarGanesh K .
