2011-06-07HID: yurex: recognize GeneralKeys wireless presenter as generic HIDTomoki Sekiyama1-1/+2
Unfortunately, the device seems to have the same Vendor ID and Product ID as YUREX leg-shakes sensors, and the commit 6bc235a2e2 ("USB: add driver for Meywa-Denki & Kayac YUREX") added the ID to hid_ignore_list. I believe that we can distinguish YUREX and the Wireless Presenter by device type. The patch below makes the driver ignore only YUREX (bInterfaceProtocol==0), and recognize Wireless Presenter (bInterfaceProtocol is keyboard or mouse) as generic HID. (I don't have the Wireless Presenter, so not yet ested.) ** YUREX lsusb information: Bus 002 Device 007: ID 0c45:1010 Microdia Device Descriptor: bLength 18 bDescriptorType 1 bcdUSB 1.10 bDeviceClass 0 (Defined at Interface level) bDeviceSubClass 0 bDeviceProtocol 0 bMaxPacketSize0 8 idVendor 0x0c45 Microdia idProduct 0x1010 bcdDevice 0.03 iManufacturer 1 JESS iProduct 2 YUREX iSerial 3 10000269 bNumConfigurations 1 Configuration Descriptor: bLength 9 bDescriptorType 2 wTotalLength 34 bNumInterfaces 1 bConfigurationValue 1 iConfiguration 0 bmAttributes 0xa0 (Bus Powered) Remote Wakeup MaxPower 100mA Interface Descriptor: bLength 9 bDescriptorType 4 bInterfaceNumber 0 bAlternateSetting 0 bNumEndpoints 1 bInterfaceClass 3 Human Interface Device bInterfaceSubClass 1 Boot Interface Subclass bInterfaceProtocol 0 None iInterface 0 HID Device Descriptor: bLength 9 bDescriptorType 33 bcdHID 1.10 bCountryCode 0 Not supported bNumDescriptors 1 bDescriptorType 34 Report wDescriptorLength 31 Report Descriptors: ** UNAVAILABLE ** Endpoint Descriptor: bLength 7 bDescriptorType 5 bEndpointAddress 0x81 EP 1 IN bmAttributes 3 Transfer Type Interrupt Synch Type None Usage Type Data wMaxPacketSize 0x0008 1x 8 bytes bInterval 10 Device Status: 0x0002 (Bus Powered) Remote Wakeup Enabled Addresses https://bugzilla.kernel.org/show_bug.cgi?id=26922 Signed-off-by: Tomoki Sekiyama <[email protected]> Cc: Greg KH <[email protected]> Cc: "Rafael J.

2011-05-23hrtimers: Reorder clock basesThomas Gleixner1-1/+1
The ordering of the clock bases is historical due to the CLOCK_REALTIME and CLOCK_MONOTONIC constants. Now the hrtimer bases have their own enumeration due to the gap between CLOCK_MONOTONIC and CLOCK_BOOTTIME. So we can be more clever as most timers end up on the CLOCK_MONOTONIC base due to the virtue of POSIX declaring that relative CLOCK_REALTIME timers are not affected by time changes. In desktop environments this is slowly changing as applications switch to absolute timers, but I've observed empty CLOCK_REALTIME bases often enough. There is no performance penalty or overhead when CLOCK_REALTIME timers are active, but in case they are not we don't skip over a full cache line.

Peter is concerned about the extra scan of CLOCK_REALTIME_COS in the timer interrupt. Yes, I did not think about it, because the solution was so elegant. I didn't like the extra list in timerfd when it was proposed some time ago, but with a rcu based list the list walk it's less horrible than the original global lock, which was held over the list iteration.

2011-05-23watchdog: Change the default timeout and configure nmi watchdog period based ↵Mandeep Singh Baines1-1/+1
on watchdog_thresh Before the conversion of the NMI watchdog to perf event, the watchdog timeout was 5 seconds. Now it is 60 seconds. For my particular application, netbooks, 5 seconds was a better timeout. With a short timeout, we catch faults earlier and are able to send back a panic. With a 60 second timeout, the user is unlikely to wait and will instead hit the power button, causing us to lose the panic info. This change configures the NMI period to watchdog_thresh and sets the softlockup_thresh to watchdog_thresh * 2. In addition, watchdog_thresh was reduced to 10 seconds as suggested by Ingo Molnar.

2011-05-23watchdog: Disable watchdog when thresh is zeroMandeep Singh Baines2-3/+3
This restores the previous behavior of softlock_thresh. Currently, setting watchdog_thresh to zero causes the watchdog kthreads to consume a lot of CPU. In addition, the logic of proc_dowatchdog_thresh and proc_dowatchdog_enabled has been factored into proc_dowatchdog.

2011-05-22netpoll: disable netpoll when enslave a deviceAmerigo Wang1-0/+1
V3: rename NETDEV_ENSLAVE to NETDEV_JOIN Currently we do nothing when we enslave a net device which is running netconsole. Neil pointed out that we may get weird results in such case, so let's disable netpoll on the device being enslaved. I think it is too harsh to prevent the device being ensalved if it is running netconsole. By the way, this patch also removes the NETDEV_GOING_DOWN from netconsole netdev notifier, because netpoll will check if the device is running or not and we don't handle NETDEV_PRE_UP neither. This patch is based on net-next-2.6. Signed-off-by: WANG Cong <[email protected]> Cc: Neil Horman <[email protected]> Signed-off-by: David S. Miller <[email protected]>

2011-05-22KVM: make guest mode entry to be rcu quiescent stateGleb Natapov1-0/+9
KVM does not hold any references to rcu protected data when it switches CPU into a guest mode. In fact switching to a guest mode is very similar to exiting to userspase from rcu point of view. In addition CPU may stay in a guest mode for quite a long time (up to one time slice). Lets treat guest mode as quiescent state, just like we do with user-mode execution.

2011-05-21KVM: Use pci_store/load_saved_state() around VM device usageAlex Williamson1-0/+1
Store the device saved state so that we can reload the device back to the original state when it's unassigned. This has the benefit that the state survives across pci_reset_function() calls via the PCI sysfs reset interface while the VM is using the device.

2011-05-21PCI: Add interfaces to store and load the device saved stateAlex Williamson1-0/+4
For KVM device assignment, we'd like to save off the state of a device prior to passing it to the guest and restore it later. We also want to allow pci_reset_funciton() to be called while the device is owned by the guest. This however overwrites and invalidates the struct pci_dev buffers, so we can't just manually call save and restore. Add generic interfaces for the saved state to be stored and reloaded back into struct pci_dev at a later time.
