2010-02-26[S390] Define new s390 ELF note sections in elf.hMichael Holzheu1-0/+5
S390 ELF core dump currently only contains the PSW, the general purpose registers, the floating point registers and the access registers stored in PRSTATUS/PRFPREG note sections. For analyzing s390 kernel problems additional registers are important. In order to be able to include these registers to a kernel ELF core dump, this patch adds the following five new note sections to elf.h: * NT_S390_TIMER: S390 timer register * NT_S390_TODCMP: S390 TOD comparator register * NT_S390_TODPREG: S390 TOD programmable register * NT_S390_CTRS: S390 control registers * NT_S390_PREFIX: S390 prefix register The new note sections have been already defined and accepted in the upstream binutils package.

2010-02-26USB: implement non-tree resume ordering constraints for PCI host controllersAlan Stern1-0/+1
This patch (as1331) adds non-tree ordering constraints needed for proper resume of PCI USB host controllers from hibernation. The main issue is that non-high-speed devices must not be resumed before the high-speed root hub, because it is the ehci_bus_resume() routine which takes care of handing the device connection over to the companion controller. If the device resume is attempted before the handover then the device won't be found and it will be treated as though it had disconnected. The patch adds a new field to the usb_bus structure; for each full/low-speed bus this field will contain a pointer to the companion high-speed bus (if one exists). It is used during normal device resume; if the hs_companion pointer isn't NULL then we wait for the root-hub device on the hs_companion bus. A secondary issue is that an EHCI controlller shouldn't be resumed before any of its companions. On some machines I have observed handovers failing if the companion controller is reinitialized after the handover. Thus, the EHCI resume routine must wait for the companion controllers to be resumed. The patch also fixes a small bug in usb_hcd_pci_probe(); an error path jumps to the wrong label, causing a memory leak.

2010-02-26PM: Allow device drivers to use dpm_wait()Rafael J. Wysocki1-0/+2
There are some dependencies between devices (in particular, between EHCI USB controllers and their OHCI/UHCI siblings) which are not reflected by the structure of the device tree. With synchronous suspend and resume these dependencies are taken into accout automatically, because the devices in question are always registered in the right order, but to meet these constraints with asynchronous suspend and resume the drivers of these devices will need to use dpm_wait() in their suspend/resume routines, so introduce a helper function allowing them to do that.

2010-02-26PM: Add facility for advanced testing of async suspend/resumeRafael J. Wysocki1-0/+11
Add configuration switch CONFIG_PM_ADVANCED_DEBUG for compiling in extra PM debugging/testing code allowing one to access some PM-related attributes of devices from the user space via sysfs. If CONFIG_PM_ADVANCED_DEBUG is set, add sysfs attribute power/async for every device allowing the user space to access the device's power.async_suspend flag and modify it, if desired. Signed-off-by: Rafael J. Wysocki <rjw@sisk.pl>
2010-02-26PM: Asynchronous suspend and resume of devicesRafael J. Wysocki3-0/+16
Theoretically, the total time of system sleep transitions (suspend to RAM, hibernation) can be reduced by running suspend and resume callbacks of device drivers in parallel with each other. However, there are dependencies between devices such that we're not allowed to suspend the parent of a device before suspending the device itself. Analogously, we're not allowed to resume a device before resuming its parent. The most straightforward way to take these dependencies into accout is to start the async threads used for suspending and resuming devices at the core level, so that async_schedule() is called for each suspend and resume callback supposed to be executed asynchronously. For this purpose, introduce a new device flag, power.async_suspend, used to mark the devices whose suspend and resume callbacks are to be executed asynchronously (ie. in parallel with the main suspend/resume thread and possibly in parallel with each other) and helper function device_enable_async_suspend() allowing one to set power.async_suspend for given device (power.async_suspend is unset by default for all devices). For each device with the power.async_suspend flag set the PM core will use async_schedule() to execute its suspend and resume callbacks. The async threads started for different devices as a result of calling async_schedule() are synchronized with each other and with the main suspend/resume thread with the help of completions, in the following way: (1) There is a completion, power.completion, for each device object. (2) Each device's completion is reset before calling async_schedule() for the device or, in the case of devices with the power.async_suspend flags unset, before executing the device's suspend and resume callbacks. (3) During suspend, right before running the bus type, device type and device class suspend callbacks for the device, the PM core waits for the completions of all the device's children to be completed. (4) During resume, right before running the bus type, device type and device class resume callbacks for the device, the PM core waits for the completion of the device's parent to be completed. (5) The PM core completes power.completion for each device right after the bus type, device type and device class suspend (or resume) callbacks executed for the device have returned.

2010-02-26PM / Runtime: Add sysfs switch for disabling device run-time PMRafael J. Wysocki2-0/+5
Add new device sysfs attribute, power/control, allowing the user space to block the run-time power management of the devices. If this attribute is set to "on", the driver of the device won't be able to power manage it at run time (without breaking the rules) and the device will always be in the full power state (except when the entire system goes into a sleep state).

2010-02-26V4L/DVB: saa7146_vv: fix regression where v4l2_device was registered too lateHans Verkuil1-0/+1
v4l2_device_register needs to be called before the i2c subdevs are loaded. However, it was called afterwards in the saa7146 driver. This caused an oops when loading the mxb and hexium drivers. The vv_init function is now split into two: one registers the v4l2_device, the other does the rest of the initialization. The three drivers that depend on this have been updated to call the new vv_devinit function. Thanks to Michael Hunold for reporting this.

2010-02-26V4L/DVB: cx25840, v4l2-subdev, ivtv, pvrusb2: Fix ivtv/cx25840 tinny audioAndy Walls1-0/+1
This change attempts to fix the ivtv tinny audio problem by keeping digitizer to encoder audio clocks running, while disabling the video clocks as needed to avoid unpredictable PCI bus hangs. To accomplish this, for the cx25840 module enabling of audio streaming had to be separated from enabling video streaming, requiring an additional v4l2_subdev_audio_op and calls to this new op in the pvrusb2 and ivtv drivers. The cx231xx and cx23885 driver use the cx25840 module for affecting only video on s_stream calls, so those drivers needed no change. The CX23418 hardware does not exhibit either the tinny audio problem nor the PCI bus hang, so the cx18 driver did not need corresponding changes. CX2341[56] based cards that are not using the CX2584x family of chips do not seem to be affected by the tinny audio problem, and this change should not affect how they are configured. It will delay their first capture by starting by another 300 msec though. Many thanks go to Argus <pthorn-ivtvd@styx2002.no-ip.org> and Martin Dauskardt <martin.dauskardt@gmx.de> whose persistent testing and investigation of this problem will hopefully fix this problem once and for all for many ivtv users.
