| |
Hello,
I would like to allow the transferring of data between ISR's, kernel and user code, without requiring copying. I envision allocating buffers in the kernel and then mapping them so that they appear at the same addresses to all code, and never being swapped out of memory.
Is this feasible for all supported Linux architectures and is there existing code that someone could point me towards?
Regards,
Wink Saville
