2006-09-25drivers/base: Platform notify needs to occur before drivers attach to the deviceBrian Walsh
The platform_notify call for Arm and PPC architectures needs to be called before the driver attaches to the device. The problem only presents itself when hotplugging certain devices while the driver is already loaded.

2006-09-25add __must_check to device management codeAndrew Morton
We're getting a lot of crashes in the sysfs/kobject/device/bus/class code and they're very hard to diagnose. I'm suspecting that in some cases this is because drivers aren't checking return values and aren't handling errors correctly. So the code blithely blunders on and crashes later in very obscure ways. There's just no reason to ignore errors which can and do occur. So the patch sprinkles __must_check all over these APIs. Causes 1,513 new warnings. Heh.

Make sysfs_remove_bin_file() void. If it detects an error, printk the file name and call dump_stack(). sysfs_hash_and_remove() now returns an error code indicating its success or failure so that sysfs_remove_bin_file() can know success/failure.

2006-09-25Driver core: add ability for devices to create and remove bin filesGreg Kroah-Hartman
Makes it easier for devices to create and remove binary attribute files so they don't have to call directly into sysfs. This is needed to help with the conversion from struct class_device to struct device. Signed-off-by: Greg Kroah-Hartman <gregkh@suse.de>
2006-09-25Class: add support for class interfaces for devicesGreg Kroah-Hartman
When moving class_device usage over to device, we need to handle class_interfaces properly with devices. This patch adds that support. Signed-off-by: Greg Kroah-Hartman <gregkh@suse.de>
2006-09-25Driver core: create devices/virtual/ treeGreg Kroah-Hartman
This change creates a devices/virtual/CLASS_NAME tree for struct devices that belong to a class, yet do not have a "real" struct device for a parent. It automatically creates the directories on the fly as needed. Cc: Kay Sievers <kay.sievers@vrfy.org> Signed-off-by: Greg Kroah-Hartman <gregkh@suse.de>
2006-09-25Driver core: add device_rename functionGreg Kroah-Hartman

2006-09-25Driver core: add ability for classes to handle devices properlyGreg Kroah-Hartman
This adds two new callbacks to the class structure: int (*dev_uevent)(struct device *dev, char **envp, int num_envp, char *buffer, int buffer_size); void (*dev_release)(struct device *dev); And one pointer: struct device_attribute * dev_attrs; which all corrispond with the same thing as the "normal" class devices do, yet this is for when a struct device is bound to a class. Someday soon, struct class_device will go away, and then the other fields in this structure can be removed too. But this is necessary in order to get the transition to work properly. Tested out on a network core patch that converted it to use struct device instead of struct class_device. Signed-off-by: Greg Kroah-Hartman <gregkh@suse.de>
2006-09-25Driver core: allow devices in classes to have no parentGreg Kroah-Hartman
This fixes an oops when a device is attached to a class, yet has no "parent" device. An example of this would be the "lo" device in the network core. We should create a "virtual" subdirectory under /sys/devices/ for these, but no one seems to agree on a proper name for it yet... Oh, and update my copyright on the driver core.

2006-09-25PM: no suspend_prepare() phaseDavid Brownell
Remove the new suspend_prepare() phase. It doesn't seem very usable, has never been tested, doesn't address fault cleanup, and would need a sibling resume_complete(); plus there are no real use cases.

Updates to match current code: - Make writes to the /sys/devices/.../power/state files fail cleanly if the device requires the irqs-off call variants. - Fix comments describing the /sys/devices/.../power/state file writes to match the code; the last several releases have invalidated the previous text.

2006-09-25PM: USB HCDs use PM_EVENT_PRETHAWDavid Brownell

2006-09-25PM: PCI and IDE handle PM_EVENT_PRETHAWDavid Brownell
Convert some framework code to handle the new PRETHAW message. - IDE just treats it like a FREEZE. - The pci_choose_state() thingie still doesn't use PCI_D0 when it gets a FREEZE (and now PRETHAW) event, which seems rather buglike but wasn't something to change with this patch.

2006-09-25PM: define PM_EVENT_PRETHAWDavid Brownell
This adds a new pm_message_t event type to use when preparing to restore a swsusp snapshot. Devices that have been initialized by Linux after resume (rather than left in power-up-reset state) may need to be reset; this new event type give drivers the chance to do that. The drivers that will care about this are those which understand more hardware states than just "on" and "reset", relying on hardware state during resume() methods to be either the state left by the preceding suspend(), or a power-lost reset. The best current example of this class of drivers are USB host controller drivers, which currently do not work through swsusp when they're statically linked. When the swsusp freeze/thaw mechanism kicks in, a troublesome third state could exist: one state set up by a different kernel instance, before a snapshot image is resumed. This mechanism lets drivers prevent that state. Signed-off-by: David Brownell <dbrownell@users.sourceforge.net> Cc: "Rafael J.

2006-09-25fix broken/dubious driver suspend() methodsDavid Brownell
Small driver suspend() fixes in preparation for the PRETHAW events: - Only compare message events for equality against PM_EVENT_* codes; not against integers, or using greater/less-than comparisons. (PM_EVENT_* should really become a __bitwise thing.) - Explicitly test for SUSPEND events (rather than not-something-else) before suspending devices. - Removes more of the confusion between a pm_message_t (wraps event code) and a "state" ... suspend() originally took a target system state. These updates are correct and appropriate even without new PM_EVENT codes. benh: "I think in the Mesh case, we should handle the freeze case as well or we might get wild DMA."

2006-09-25[PATCH] VIDIOC_ENUMSTD bugJonathan Corbet
The v4l2 API documentation for VIDIOC_ENUMSTD says: To enumerate all standards applications shall begin at index zero, incrementing by one until the driver returns EINVAL. The actual code, however, tests the index this way: if (index<=0 || index >= vfd->tvnormsize) { ret=-EINVAL; So any application which passes in index=0 gets EINVAL right off the bat - and, in fact, this is what happens to mplayer. So I think the following patch is called for, and maybe even appropriate for a 2.6.18.x stable release.

2006-09-25[PATCH] load_module: no BUG if module_subsys uninitializedEd Swierk
Invoking load_module() before param_sysfs_init() is called crashes in mod_sysfs_setup(), since the kset in module_subsys is not initialized yet. In my case, net-pf-1 is getting modprobed as a result of hotplug trying to create a UNIX socket. Calls to hotplug begin after the topology_init initcall. Another patch for the same symptom (module_subsys-initialize-earlier.patch) moves param_sysfs_init() to the subsys initcalls, but this is still not early enough in the boot process in some cases. In particular, topology_init() causes /sbin/hotplug to run, which requests net-pf-1 (the UNIX socket protocol) which can be compiled as a module. Moving param_sysfs_init() to the postcore initcalls fixes this particular race, but there might well be other cases where a usermodehelper causes a module to load earlier still. The patch makes load_module() return an error rather than crashing the kernel if invoked before module_subsys is initialized.

Problem description: We have additional_cpus= option for allocating possible_cpus. But nid for possible cpus are not fixed at boot time. cpus which is offlined at boot or cpus which is not on SRAT is not tied to its node. This will cause panic at cpu onlining. Usually, pxm_to_nid() mapping is fixed at boot time by SRAT. But, unfortunately, some system (my system!) do not include full SRAT table for possible cpus. (Then, I use additiona_cpus= option.)
