Subject: [patch/rfc 0/2] handle_threaded_irq()
Date: Wednesday 18th March 2009 02:14:53 UTC (over 7 years ago)
This is a followup to help address one of the omissions in the threaded IRQ patches (v2) posted recently. To recap, those provided a quickcheck() routine that could wake an irq thread, and a way to register a handler using that mechanism. This addresses an orthogonal problem: given some thread demultiplexing the subsidiary IRQs reported to some top-level interrupt, how can that kick in flow handlers chaining to the subsidiary IRQs' handlers? The answer here is more or less as suggested by Thomas: using handle_threaded_irq(), a flow handler which doesn't use handle_IRQ_event() since that doesn't much like being called from thread context, at least when lockdep is active. These two patches: - add handle_threaded_irq() flow handler; - kick it in for some twl4030 code Tested on 2.6.29-rc8 code, both with and without the v2 irqthread patches.
