That means we mark the interrupt disabled, but\nleave the hardware unmasked. That\u0027s an optimization because we avoid\nthe hardware access for the common case where no interrupt happens\nafter we marked it disabled. If an interrupt happens, then the\ninterrupt flow handler masks the line at the hardware level and marks\nit pending.\n\nSuspend makes use of this delayed disable as it \"disables\" all\ninterrupts when preparing the suspend transition. Right before the\nsystem goes into hardware suspend state it checks whether one of the\ninterrupts which is marked as a wakeup interrupt came in after\ndisabling it.\n\nMost interrupt chips have a separate register which selects the\ninterrupts which can wake up the system from suspend, so we don\u0027t have\nto mask any on the non wakeup interrupts.\n\nBut now we have to deal with brilliant designed hardware which lacks\nsuch a wakeup configuration facility. For such hardware it\u0027s necessary\nto mask all non wakeup interrupts before going into suspend in order\nto avoid the wakeup from random interrupts.\n\nRather than working around this in the affected interrupt chip\nimplementations we can solve this elegant in the core code itself.\n\nAdd a flag IRQCHIP_MASK_ON_SUSPEND which can be set by the irq chip\nimplementation to indicate, that the interrupts which are not selected\nas wakeup sources must be masked in the suspend path. Mask them in the\nloop which checks the wakeup interrupts pending flag.\n\nSigned-off-by: Thomas Gleixner \u003ctglx@linutronix.de\u003e\nReviewed-by: Abhijeet Dharmapurikar \u003cadharmap@codeaurora.org\u003e\nLKML-Reference: \u003calpine.LFD.2.00.1103112112310.2787@localhost6.localdomain6\u003e\n\n" }, { "commit": "a439520f8b18917b322f576be04c54aba84bb044", "tree": "b835a4b32c057408ed35292c02ad214341e317ed", "parents": [ "77694b408abb8f92195ad5ed6ce5492f1d794c77" ], "author": { "name": "Thomas Gleixner", "email": "tglx@linutronix.de", "time": "Fri Feb 04 18:46:16 2011 +0100" }, "committer": { "name": "Thomas Gleixner", "email": "tglx@linutronix.de", "time": "Sat Feb 19 12:58:25 2011 +0100" }, "message": "genirq: Implement irq_data based move_*_irq() versions\n\nNo need to lookup the irq descriptor when calling from a chip callback\nfunction which has irq_data already handy.\n\nSigned-off-by: Thomas Gleixner \u003ctglx@linutronix.de\u003e\n" }, { "commit": "77694b408abb8f92195ad5ed6ce5492f1d794c77", "tree": "a0f7e81a0a155523f69146cd560cc2f49543a99e", "parents": [ "781295762defc709a609efc01d8bb065276cd9a2" ], "author": { "name": "Thomas Gleixner", "email": "tglx@linutronix.de", "time": "Tue Feb 15 10:33:57 2011 +0100" }, "committer": { "name": "Thomas Gleixner", "email": "tglx@linutronix.de", "time": "Sat Feb 19 12:58:24 2011 +0100" }, "message": "genirq; Add fasteoi irq_chip quirk\n\nSome chips want irq_eoi() only called when an interrupt is actually\nhandled.

That allows:\n\n - Fast lookup of a free slot\n - Allows the removal of descriptors\n - Prevents the create/destroy race\n - Bulk allocation of consecutive irq ranges\n - Basic design is ready for migration of life descriptors after\n further cleanups\n\nThe bitmap is also used in the SPARSE_IRQ\u003dn case for lookup and\nraceless (de)allocation of irq numbers. So it removes the requirement\nfor looping through the descriptor array to find slots.\n\nRight now it uses sparse_irq_lock to protect the bitmap and the radix\ntree, but after cleaning up all users we should be able convert that\nto a mutex and to switch the radix_tree and decriptor allocations to\nGFP_KERNEL.\n\n[ Folded in a bugfix from Yinghai Lu ]\n\nSigned-off-by: Thomas Gleixner \u003ctglx@linutronix.de\u003e\nReviewed-by: Ingo Molnar \u003cmingo@elte.hu\u003e\n" }, { "commit": "1318a481fc37c503a901b96ae06b692ca2b21af5", "tree": "2b1bb8f52af5938759af38efdfa8a868b02d5804", "parents": [ "d895f51ebb54cefe367bda135fcf2cd734d51d03" ], "author": { "name": "Thomas Gleixner", "email": "tglx@linutronix.de", "time": "Mon Sep 27 21:01:37 2010 +0200" }, "committer": { "name": "Thomas Gleixner", "email": "tglx@linutronix.de", "time": "Tue Oct 12 16:39:06 2010 +0200" }, "message": "genirq: Provide default irq init flags\n\nArch code sets it\u0027s own irq_desc.status flags right after boot and for\ndynamically allocated interrupts.
