Development: Driver Performance Optimisations
Revision as of 02:50, 19 September 2009 by CityK
In some cases it may be critical to do things really right, so here is a list of just the most important points when working on a DVB driver:
- Don't do heavy work in interrupt context. Use work queues.
- Avoid busy-polling.
- Don't use extra-threads unless really necessairy. They are usually avoidable.
- Don't call the Software Demultiplexer from interrupt context if avoidable.
