There are still problems to be expected is something\nattaches to a bus type where the code can hook in different struct\ndevice sub-classes (which is imho a big bogosity but I won\u0027t even try to\nargue that case now) but it will solve nicely a number of issues I\u0027ve\nhad so far.\n\nThat also means that clients interested in registering for such\nnotifications have to do it before devices are added and after bus types\nare registered. Fortunately, most bus types that matter for the various\nusage scenarios I have in mind are registerd at postcore_initcall time,\nwhich means I have a really nice spot at arch_initcall time to add my\nnotifiers.\n\nThere are 4 notifications provided. Device being added (before hooked to\nthe bus) and removed (failure of previous case or after being unhooked\nfrom the bus), along with driver being bound to a device and about to be\nunbound.\n\nThe usage I have for these are:\n\n - The 2 first ones are used to maintain a struct device_ext that is\nhooked to struct device.firmware_data. This structure contains for now a\npointer to the Open Firmware node related to the device (if any), the\nNUMA node ID (for quick access to it) and the DMA operations pointers \u0026\niommu table instance for DMA to/from this device. For bus types I own\n(like IBM VIO or EBUS), I just maintain that structure directly from the\nbus code when creating the devices. But for bus types managed by generic\ncode like PCI or platform (actually, of_platform which is a variation of\nplatform linked to Open Firmware device-tree), I need this notifier.\n\n - The other two ones have a completely different usage scenario. I have\ncases where multiple devices and their drivers depend on each other. For\nexample, the IBM EMAC network driver needs to attach to a MAL DMA engine\nwhich is a separate device, and a PHY interface which is also a separate\ndevice. They are all of_platform_device\u0027s (well, about to be with my\nupcoming patches) but there is no say in what precise order the core\nwill \"probe\" them and instanciate the various modules. The solution I\nfound for that is to have the drivers for emac to use multithread_probe,\nand wait for a driver to be bound to the target MAL and PHY control\ndevices (the device-tree contains reference to the MAL and PHY interface\nnodes, which I can then match to of_platform_devices). Right now, I\u0027ve\nbeen polling, but with that notifier, I can more cleanly wait (with a\ntimeout of course).\n\nSigned-off-by: Benjamin Herrenschmidt \u003cbenh@kernel.crashing.org\u003e\nSigned-off-by: Greg Kroah-Hartman \u003cgregkh@suse.de\u003e\n\n" }, { "commit": "d9fd4d3b317a231e47f31d64d66c8cc7765d458f", "tree": "d4a80654a42707bbb541d52ca1fffc565e92e96b", "parents": [ "f70fa6296c2ec8f541f0a9b406ccc2d9d127d639" ], "author": { "name": "Jeff Garzik", "email": "jeff@garzik.org", "time": "Wed Oct 04 07:48:03 2006 -0400" }, "committer": { "name": "Greg Kroah-Hartman", "email": "gregkh@suse.de", "time": "Wed Oct 18 12:49:56 2006 -0700" }, "message": "Driver core: bus: remove indentation level\n\nBefore potentially fixing up these functions, this cosmetic change\nreduces the indentation level to make the code easier to read and\nmaintain.\n\nNo functional changes at all.\n\nSigned-off-by: Jeff Garzik \u003cjeff@garzik.org\u003e\nSigned-off-by: Greg Kroah-Hartman \u003cgregkh@suse.de\u003e\n\n" }, { "commit": "f70fa6296c2ec8f541f0a9b406ccc2d9d127d639", "tree": "f9fd9bbb13a62683c6b41612cfb34fa3894f8676", "parents": [ "952ab431cd36c7ab573f685af8679c3677cbdc29" ], "author": { "name": "Alan Stern", "email": "stern@rowland.harvard.edu", "time": "Thu Oct 05 17:03:24 2006 -0400" }, "committer": { "name": "Greg Kroah-Hartman", "email": "gregkh@suse.de", "time": "Wed Oct 18 12:49:55 2006 -0700" }, "message": "Driver core: Don\u0027t ignore error returns from probing\n\nThis patch (as797) fixes device_add() in the driver core.

The\nproblem is that __driver_attach() tries to acquire the device\u0027s\nparent\u0027s semaphore, but the caller of bus_remove_device() is quite\nlikely to own that semaphore already.\n\nIt isn\u0027t sufficient just to replace klist_remove() with klist_del().\nDoing so runs the risk that the device would remain on the bus\u0027s klist\nof devices for some time, and so could be bound to another driver even\nafter it was unregistered. What\u0027s needed is a new way to distinguish\nwhether or not a device is registered, based on a criterion other than\nwhether its klist_node is linked into the bus\u0027s klist of devices. That\nway driver binding can fail when the device is unregistered, even if\nit is still linked into the klist.\n\nThis patch (as782) implements the solution, by adding a new bitflag to\nindiate when a struct device is registered, by testing the flag before\nallowing a driver to bind a device, and by changing the definition of\nthe device_is_registered() inline.\n\nSigned-off-by: Alan Stern \u003cstern@rowland.harvard.edu\u003e\nSigned-off-by: Greg Kroah-Hartman \u003cgregkh@suse.de\u003e\n\n" }, { "commit": "f86db396ff455ed586751d21816a1ebd431264e5", "tree": "dfbeb27206b673ed46482b18ee6d779786be7ed1", "parents": [ "370226449ced358e52d198081120826ef52c166b" ], "author": { "name": "Andrew Morton", "email": "akpm@osdl.org", "time": "Mon Aug 14 22:43:20 2006 -0700" }, "committer": { "name": "Greg Kroah-Hartman", "email": "gregkh@suse.de", "time": "Mon Sep 25 21:08:39 2006 -0700" }, "message": "drivers/base: check errors\n\nAdd lots of return-value checking.\n\n\u003cpcornelia.huck@de.ibm.com\u003e: fix bus_rescan_devices()]\nCc: \"Randy.Dunlap\" \u003crdunlap@xenotime.net\u003e\nSigned-off-by: Cornelia Huck \u003ccornelia.huck@de.ibm.com\u003e\nSigned-off-by: Andrew Morton \u003cakpm@osdl.org\u003e\nSigned-off-by: Greg Kroah-Hartman \u003cgregkh@suse.de\u003e\n\n" }, { "commit": "35acfdd7253025e8441883fd8f879f5240844f95", "tree": "d1fb2d170964572c4b5446f73a44db88599c0e46", "parents": [ "9de72ee59029087fc8300633113c75a5fe73a7b8" ], "author": { "name": "Yoichi Yuasa", "email": "yoichi_yuasa@tripeaks.co.jp", "time": "Sat Jul 15 01:30:11 2006 +0900" }, "committer": { "name": "Greg Kroah-Hartman", "email": "gregkh@suse.de", "time": "Mon Sep 25 21:08:39 2006 -0700" }, "message": "Driver core: fixed add_bind_files() definition\n\nWhen CONFIG_HOTPLUG is n, add_bind_files() definition is wrong.\nThis patch has fixed it.\n\nSigned-off-by: Yoichi Yuasa \u003cyoichi_yuasa@tripeaks.co.jp\u003e\nSigned-off-by: Greg Kroah-Hartman \u003cgregkh@suse.de\u003e\n\n" }, { "commit": "7e4ef085ea4b00cfc34e854edf448c729de8a0a5", "tree": "cc8b12d3b25e0b5a6cc2524faccc2d05dcff61c8", "parents": [ "42734dafa43e453a8b6769a5ebd3a01ffc1fd116" ], "author": { "name": "Adrian Bunk", "email": "bunk@stusta.de", "time": "Mon Jun 26 22:26:56 2006 +0200" }, "committer": { "name": "Greg Kroah-Hartman", "email": "gregkh@suse.de", "time": "Wed Jul 12 16:09:08 2006 -0700" }, "message": "[PATCH] Driver core: bus.c cleanups\n\nThis patch contains the following cleanups:\n- make the needlessly global bus_subsys static\n- #if 0 the unused find_bus()\n\nSigned-off-by: Adrian Bunk \u003cbunk@stusta.de\u003e\nSigned-off-by: Greg Kroah-Hartman \u003cgregkh@suse.de\u003e\n" }, { "commit": "6ab3d5624e172c553004ecc862bfeac16d9d68b7", "tree": "6d98881fe91fd9583c109208d5c27131b93fa248", "parents": [ "e02169b682bc448ccdc819dc8639ed34a23cedd8" ], "author": { "name": "Jörn Engel", "email": "joern@wohnheim.fh-wedel.de", "time": "Fri Jun 30 19:25:36 2006 +0200" }, "committer": { "name": "Adrian Bunk", "email": "bunk@stusta.de", "time": "Fri Jun 30 19:25:36 2006 +0200" }, "message": "Remove obsolete #include \u003clinux/config.h\u003e\n\nSigned-off-by: Jörn Engel \u003cjoern@wohnheim.fh-wedel.de\u003e\nSigned-off-by: Adrian Bunk \u003cbunk@stusta.de\u003e\n" }, { "commit": "b9d9c82b4d081feb464f62dfc786c8621d09ecd2", "tree": "511d15b4d7aaba80a2c0fe49622a3224ca386122", "parents": [ "23681e479129854305da1da32f7f1eaf635ef22c" ], "author": { "name": "Kay Sievers", "email": "kay.sievers@suse.de", "time": "Thu Jun 15 15:31:56 2006 +0200" }, "committer": { "name": "Greg Kroah-Hartman", "email": "gregkh@suse.de", "time": "Wed Jun 21 12:40:49 2006 -0700" }, "message": "[PATCH] Driver core: add generic \"subsystem\" link to all devices\n\nLike the SUBSYTEM\u003d key we find in the environment of the uevent, this\ncreates a generic \"subsystem\" link in sysfs for every device.

This facility is needed by USB device drivers,\nowing to the peculiar way USB devices work:\n\n\tA device provides multiple interfaces, and drivers are bound\n\tto interfaces rather than to devices;\n\n\tNevertheless a reset, reset-configuration, suspend, or resume\n\taffects the entire device and requires the caller to hold the\n\tlock for the device, not just a lock for one of the interfaces.\n\nSince a USB driver\u0027s probe method is always called with the interface\nlock held, the locking order rules (always lock parent before child)\nprevent these methods from acquiring the device lock. The solution\nprovided here is to call all probe and remove methods, for all devices\n(not just USB), with the parent lock already acquired.\n\nAlthough currently only the USB subsystem requires these changes, people\nhave mentioned in prior discussion that the overhead of acquiring an\nextra semaphore in all the prove/remove sequences is not overly large.\n\nUp to now, the USB core has been using its own set of private\nsemaphores. A followup patch will remove them, relying entirely on the\ndevice semaphores provided by the driver core.\n\nThe code paths affected by this patch are:\n\n\tdevice_add and device_del: The USB core already holds the parent\n\tlock, so no actual change is needed.\n\n\tdriver_register and driver_unregister: The driver core will now\n\tlock both the parent and the device before probing or removing.\n\n\tdriver_bind and driver_unbind (in sysfs): These routines will\n\tnow lock both the parent and the device before binding or\n\tunbinding.\n\n\tbus_rescan_devices: The helper routine will lock the parent\n\tbefore probing a device.\n\nI have not tested this patch for conflicts with other subsystems. As\nfar as I can see, the only possibility of conflict would lie in the\nbus_rescan_devices pathway, and it seems pretty remote. Nevertheless,\nit would be good for this to get a lot of testing in -mm.\n\nSigned-off-by: Alan Stern \u003cstern@rowland.harvard.edu\u003e\nSigned-off-by: Greg Kroah-Hartman \u003cgregkh@suse.de\u003e\n" }, { "commit": "2b08c8d0468866f86da97f836c6ac14338cb81a9", "tree": "eca60a3b6811a825cd3642a666aa523a18fe484b", "parents": [ "133747e8d1e912863edfb3869e36b97b9939d4fc" ], "author": { "name": "Alan Stern", "email": "stern@rowland.harvard.edu", "time": "Wed Nov 23 15:43:50 2005 -0800" }, "committer": { "name": "Linus Torvalds", "email": "torvalds@g5.osdl.org", "time": "Wed Nov 23 23:03:06 2005 -0800" }, "message": "[PATCH] Small fixes to driver core\n\nThis patch (as603) makes a few small fixes to the driver core:\n\nChange spin_lock_irq for a klist lock to spin_lock;\n\nFix reference count leaks;\n\nMinor spelling and formatting changes.\n\nSigned-off-by: Alan Stern \u003cstern@rowland.harvard.edu\u003e\nAcked-by Patrick Mochel \u003cmochel@digitalimplant.org\u003e\nSigned-off-by: Greg Kroah-Hartman \u003cgregkh@suse.de\u003e\nSigned-off-by: Linus Torvalds \u003ctorvalds@osdl.org\u003e\n" }, { "commit": "34bb61f9ddabd7a7f909cbfb05592eb775f6662a", "tree": "06232f6fc975bd279236fd8005c7d5528220ec68", "parents": [ "df4edad1787bbfa3c9c10824e4f11e9f4a7ec5c6" ], "author": { "name": "James Bottomley", "email": "James.Bottomley@HansenPartnership.com", "time": "Tue Sep 06 16:56:51 2005 -0700" }, "committer": { "name": "Linus Torvalds", "email": "torvalds@g5.osdl.org", "time": "Wed Sep 07 18:26:54 2005 -0700" }, "message": "[PATCH] fix klist semantics for lists which have elements removed on traversal\n\nThe problem is that klists claim to provide semantics for safe traversal of\nlists which are being modified.
