Add min_timeout (minimum timeout) and max_timeout values so that the framework can check if the new timeout value is between the minimum and maximum timeout values. If both values are 0, then the framework will leave the check for the watchdog device driver itself.

Add support for extra ioctl calls by adding a ioctl watchdog operation. This operation will be called before we do our own handling of ioctl commands. This way we can override the internal ioctl command handling and we can also add extra ioctl commands. The ioctl watchdog operation should return the appropriate error codes or -ENOIOCTLCMD if the ioctl command should be handled through the internal ioctl handling of the framework.

The WatchDog Timer Driver Core is a framework that contains the common code for all watchdog-driver's. It also introduces a watchdog device structure and the operations that go with it. This is the introduction of this framework. This part supports the minimal watchdog userspace API (or with other words: the functionality to use /dev/watchdog's open, release and write functionality as defined in the simplest watchdog API). Extra functionality will follow in the next set of patches.

There are no reads in these functions, so if MMIO writes are posted, the writes in enable/disable may not have completed by the time these functions return. If the functions run from different CPUs, it's in theory possible for the writes to be interleaved, which would be disastrous for this driver. At the very least, we need an mmiowb() before releasing the lock, but since it seems desirable for the watchdog timer to be actually stopped or reset when these functions return, read the lock register to force the writes out.

At least on the Versatile Express' V2M, calling wdt_disable followed by wdt_enable, for instance by running the following sequence: echo V > /dev/watchdog; echo V > /dev/watchdog results in an immediate reset. The wdt_disable function writes 0 to the load register; while the watchdog interrupts are disabled at this point, this special value is defined to trigger an interrupt immediately. It appears that in this instance, the reset happens when the interrupts are subsequently enabled by wdt_enable. Putting in a short delay after writing a new load value in wdt_enable solves the issue, but it seems cleaner to simply never write 0 to the load register at all: according to the hardware docs, writing 0 to the control register suffices to stop the counter, and the write of 0 to the load register is questionable anyway since this register resets to 0xffffffff.

Inspired by Nat Gurumoorthy's recent patches for cleaning up the it87 drivers to use request_muxed_region for accessing the SuperIO area on these chips, and the fact I have a GPIO driver for the pc8741x basically ready for submission, here is a patch to cleanup the pc87413 watchdog driver to use request_muxed_region for accessing the SuperIO area. It also pulls out the details about the SWC IO area on initial driver load, and properly does a request_region for that area - there's no requirement to touch the SuperIO area after doing the initial watchdog enable and IO base retrieval. While I have hardware with a pc87413 on it it is not wired in a way that allows the watchdog to reboot the machine, so I have not been able to fully test these changes - I have checked that the driver correctly initialises itself still and requests the SWC io region ok.

由 Nat Gurumoorthy 提交于
Changes the it87 watchdog drivers to use "request_muxed_region". Serialize access to the hardware by using "request_muxed_region" macro defined by Alan Cox. Call to this macro will hold off the requestor if the resource is currently busy. The use of the above macro makes it possible to get rid of spinlocks in it8712f_wdt.c and it87_wdt.c watchdog drivers. This also greatly simplifies the implementation of it87_wdt.c driver. "superio_enter" will return an error if call to "request_muxed_region" fails. Rest of the code change is to ripple an error return from superio_enter to the top level.

Align unfenced buffers on older hardware to the power-of-two object size. The docs suggest that it should be possible to align only to a power-of-two tile height, but using the already computed fence size is easier and always correct. We also have to make sure that we unbind misaligned buffers upon tiling changes. In order to prevent a repetition of this bug, we change the interface to the alignment computation routines to force the caller to provide the requested alignment and size of the GTT binding rather than assume the current values on the object.

There is no software fallback implemented for SCTP or FCoE checksumming, and so it should not be passed on by software devices like bridge or bonding. For VLAN devices, this is different. First, the driver for underlying device should be prepared to get offloaded packets even when the feature is disabled (especially if it advertises it in vlan_features). Second, devices under VLANs do not get replaced without tearing down the VLAN first. This fixes a mess I accidentally introduced while converting bonding to ndo_fix_features.
