Subject: Zero copy between ISR, kernel and User
Date: Tue, 26 Sep 2006 21:01:45 -0700 [thread overview]
Message-ID: <4519F7A9.4050807@saville.com> (raw)
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
