* hwmon: (it87) Validate auto pwm settingsJean Delvare2010-03-05
| | | | | | | | Before switching to automatic fan control mode, make sure that all the trip points make sense. Otherwise, the control loop could lead to weird fan behavior. Signed-off-by: Jean Delvare <khali@linux-fr.org>
* hwmon: (it87) Add support for old automatic fan speed controlJean Delvare2010-03-05
| | | | | | | | | | | | | | Add support for the automatic fan speed control interface as implemented by IT8705F chips up to revision F and IT8712F chips up to revision G. This implementation fits very well in our standard sysfs interface. I implemented the old and not the new interface because the only chip I have at hand is an old one, and the new interface is more difficult to map to the standard sysfs interface. Adding support later should be possible though, if someone with a supported chip is interested. Signed-off-by: Jean Delvare <khali@linux-fr.org>

* hwmon: (lm90) Add SMBus alert supportJean Delvare2010-03-05
| | | | | | | | | | | | | | Tested successfully with an ADM1032 chip on its evaluation board. It should work fine with all other chips as well. At this point this is more of a proof-of-concept, we don't do anything terribly useful on SMBus alert: we simply log the event. But this could later evolve into libsensors signaling so that user-space applications can take an appropriate action.

VERBOSE_IDE_CD_ERRORS has been replace by config option CONFIG_BLK_DEV_IDECD_VERBOSE_ERRORS. STANDARD_ATAPI is no longer needed, since the non-standard drivers, which required bcd2bin are now detected, and there's a flag for them. NO_DOOR_LOCKING is now a sysctl parameter for cdrom drivers. CDROM_NBLOCKS_BUFFER is not used anymore. The READAUDIO is now in cdrom.c and it allocates as much as user space has requested to read, backing off if it fails. TEST is not there anymore or in cdrom either. ide allows to send ATA commands through ioctl, although it may be helpful to send MMC packets through the cdrom layer directly.

All off the 83xx device trees in arch/powerpc/boot/dts/ specify 5 interrupts per DMA controller: one for the controller, and one for each channel. These interrupts are all attached to the same IRQ line. This causes an interesting situation if two channels interrupt at the same time. The per-controller handler will handle the first channel, and the per-channel handler will handle the remaining channels. Instead of this mess, we fix the bug in the per-controller handler, and make it handle all channels that generated an interrupt. When a per-controller handler is specified in the device tree, we prefer to use the shared handler instead of the per-channel handler. The 85xx/86xx controllers do not have a per-controller interrupt, and instead use a per-channel interrupt. This behavior has not been changed. Signed-off-by: Ira W.

This involves numerous changes throughout usbcore, especially to hub.c and driver.c. Perhaps the most notable change is that CONFIG_USB_SUSPEND now depends on CONFIG_PM_RUNTIME instead of CONFIG_PM. Several fields in the usb_device and usb_interface structures are no longer needed. Some code which used to depend on CONFIG_USB_PM now depends on CONFIG_USB_SUSPEND (requiring some rearrangement of header files). The only visible change in behavior should be that following a system sleep (resume from RAM or resume from hibernation), autosuspended USB devices will be resumed just like everything else. They won't remain suspended. But if they aren't in use then they will naturally autosuspend again in a few seconds.

If a driver knows that its device can handle suspends and resumes correctly, it can enable autosuspend all by itself. This is equivalent to the user writing "auto" to the device's power/level attribute. The implementation differs slightly from what it used to be. Now autosuspend is disabled simply by doing usb_autoresume_device() (to increment the usage counter) and enabled by doing usb_autosuspend_device() (to decrement the usage counter). The set_level() attribute method is updated to use the new routines, and the USB Power-Management documentation is updated. The patch adds a usb_enable_autosuspend() call to the hub driver's probe routine, allowing the special-case code for hubs in quirks.c to be removed.

It's conditional on CONFIG_USB_DEBUG, so it won't affect normal users. The new check makes sure that the actual type of the endpoint described by urb->pipe agrees with the type encoded in the pipe value. The USB error code documentation is updated to include the code returned by the new check, and the usbfs SUBMITURB handler is updated to use the correct pipe type when legacy user code tries to submit a bulk transfer to an interrupt endpoint.

The maximum number of values that can be set at once is 7 which means the device will not get enough data to work with and none of the configuration values will be used. At least one existing cxacru-cf.bin file contains invalid data which will prevent the modem from syncing properly. Fixing it is likely to break existing systems, and the new sysfs interface for setting configuration parameters can provide the same functionality.

Until the day I somehow find out a model or BIOS cut date to not provide this feature to ThinkPads that can do video switching through X RandR, change permissions so that only processes with CAP_SYS_ADMIN can access any sort of video output control state. This bug could be considered a local DoS I suppose, as it allows any non-privledged local user to cause some versions of X.org to hard-crash some ThinkPads.

The SMBus alert protocol allows several SMBus slave devices to share a single interrupt pin on the SMBus master, while still allowing the master to know which slave triggered the interrupt. This is based on preliminary work by David Brownell. The key difference between David's implementation and mine is that his was part of i2c-core, while mine is split into a separate, standalone module named i2c-smbus. The i2c-smbus module is meant to include support for all SMBus extensions to the I2C protocol in the future. The benefit of this approach is a zero cost for I2C bus segments which do not need SMBus alert support. Where David's implementation increased the size of struct i2c_adapter by 7% (40 bytes on i386), mine doesn't touch it. Where David's implementation added over 150 lines of code to i2c-core (+10%), mine doesn't touch it. The only change that touches all the users of the i2c subsystem is a new callback in struct i2c_driver (common to both implementations.) I seem to remember Trent was worried about the footprint of David'd implementation, hopefully mine addresses the issue.

This will reduce latencies for thin streams that are not able to trigger fast retransmissions due to high packet interarrival time. This mechanism is only active if enabled by iocontrol or syscontrol and the stream is identified as thin. Signed-off-by: Andreas Petlund <apetlund@simula.no> Signed-off-by: David S.
