I need a realtime behavour in the (-current) kernel with 1ms resolution and a presision of 500us. I thought about these two ways: - use timeout(9), but it seems that on i386 we only have a resolution of 10ms. And I don't know of what presision quality I can expect. Can the resolution changed to 1ms as we have on alpha? - attach to the clock service routine. I asume the presision will be good enough. But how can I find out the resolution on a given hardware? What is the best way to solve the problem? -- B.Walter BWCT http://www.bwct.de ticso@bwct.de info@bwct.de
