So the easiest way is to run the sub device\nhandlers in the context of the demultiplexing handler thread.\n\nTo avoid that a separate thread is created for the subdevices the\nfunction set_nested_irq_thread() is provided which sets the\nIRQ_NESTED_THREAD flag in the interrupt descriptor.\n\nA driver which calls request_threaded_irq() must not be aware of the\nfact that the threaded handler is called in the context of the\ndemultiplexing handler thread. The setup code checks the\nIRQ_NESTED_THREAD flag which was set from the irq chip setup code and\ndoes not setup a separate thread for the interrupt. The primary\nfunction which is provided by the device driver is replaced by an\ninternal dummy function which warns when it is called.\n\nFor the demultiplexing handler a helper function handle_nested_irq()\nis provided which calls the demux interrupt thread function in the\ncontext of the caller and does the proper interrupt accounting and\ntakes the interrupt disabled status of the demultiplexed subdevice\ninto account.\n\nSigned-off-by: Thomas Gleixner \u003ctglx@linutronix.de\u003e\nCc: Mark Brown \u003cbroonie@opensource.wolfsonmicro.com\u003e\nCc: Dmitry Torokhov \u003cdmitry.torokhov@gmail.com\u003e\nCc: Trilok Soni \u003csoni.trilok@gmail.com\u003e\nCc: Pavel Machek \u003cpavel@ucw.cz\u003e\nCc: Brian Swetland \u003cswetland@google.com\u003e\nCc: Joonyoung Shim \u003cjy0922.shim@samsung.com\u003e\nCc: m.szyprowski@samsung.com\nCc: t.fujak@samsung.com\nCc: kyungmin.park@samsung.com,\nCc: David Brownell \u003cdavid-b@pacbell.net\u003e\nCc: Daniel Ribeiro \u003cdrwyrm@gmail.com\u003e\nCc: arve@android.com\nCc: Barry Song \u003c21cnbao@gmail.com\u003e\n\n" }, { "commit": "70aedd24d20e75198f5a0b11750faabbb56924e2", "tree": "8492641c61aa3af6f4dea421b8f628efe6fc92bd", "parents": [ "b25c340c195447afb1860da580fe2a85a6b652c5" ], "author": { "name": "Thomas Gleixner", "email": "tglx@linutronix.de", "time": "Thu Aug 13 12:17:48 2009 +0200" }, "committer": { "name": "Thomas Gleixner", "email": "tglx@linutronix.de", "time": "Mon Aug 17 10:54:05 2009 +0200" }, "message": "genirq: Add buslock support\n\nSome interrupt chips are connected to a \"slow\" bus (i2c, spi ...).
