2006-09-25Driver Core: add ability for drivers to do a threaded probeGreg Kroah-Hartman
This adds the infrastructure for drivers to do a threaded probe, and waits at init time for all currently outstanding probes to complete. A new kernel thread will be created when the probe() function for the driver is called, if the multithread_probe bit is set in the driver saying it can support this kind of operation. I have tested this with USB and PCI, and it works, and shaves off a lot of time in the boot process, but there are issues with finding root boot disks, and some USB drivers assume that this can never happen, so it is currently not enabled for any bus type. Individual drivers can enable this right now if they wish, and bus authors can selectivly turn it on as well, once they determine that their subsystem will work properly with it.

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.

2006-09-25sysfs_remove_bin_file: no return value, dump_stack on errorRandy.Dunlap
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. Convert the only driver that checked the return value of sysfs_remove_bin_file(). Signed-off-by: Randy Dunlap <rdunlap@xenotime.net> Signed-off-by: Greg Kroah-Hartman <gregkh@suse.de>
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
The network layer needs this to convert to using struct device instead of a struct class_device. Signed-off-by: Greg Kroah-Hartman <gregkh@suse.de>
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: issue 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.

2006-09-25fix 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.
