Message-ID: To: kernelnewbies@lists.kernelnewbies.org List-Id: kernelnewbies.lists.kernelnewbies.org some colleagues are considering implementing some user space drivers that need to recognize and process interrupts. i'm aware of the possibilities -- UIO, for example -- but other than the technical possibility of doing that, can anyone provide feedback on the viability or benchmarking of that? is there an example someone can point at that demonstrates the goodness or not of such an approach? has anyone out there done this, and lived to regret it in terms of performance? thanks. rday -- ======================================================================== Robert P.
