| * ACPI / PM: Fix problems with acpi_pm_device_sleep_state()Rafael J. Wysocki2010-10-152-10/+18
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | There is a number of problems with acpi_pm_device_sleep_state() now. First, if _S0W is not defined, it prevents devices from being put into D3 by PCI runtime PM, which shouldn't happen. Second, it shouldn't use adev->wakeup.state.enabled, because if it's set, it only means that either the device is permanently enabled to wake up the system, or that it has been enabled to do that through /proc/acpi/wakeup. Finally, it should be compiled if CONFIG_PM_SLEEP is not set, so that PCI runtime PM works correctly in that case. Fix these problems.

| | | * | ACPI: Do not export hid/modalias sysfs file for ACPI objects without a HIDThomas Renninger2010-10-011-16/+20
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Boot and compile tested. The fact that pnp.ids can now be empty needs testing on some further machines, though. This should handle a "modprobe is wrongly called by udev" issue: https://bugzilla.kernel.org/show_bug.cgi?id=19162 Modaliase files in /sys/devices/LNXSYSTM:00/ went down from 113 to 71 on my tested system. This is a sysfs change, but userspace must already be able to handle it. Also do not fill up pnp.ids list with a "struct hid" entry. This comment: * This generic ID isn't useful for driver binding, but it provides * the useful property that "every acpi_device has an ID." is still half way true: Best you never touch pnp.ids list directly or make sure it can be empty, instead use: char *acpi_device_hid() which always returns a value ("device" as a dummy if the object has no hid).

In this case, it reports the LastFullChargedCapacity == 100, BatteryPresentRate = 0xFFFFFFFF, and BatteryRemaingCapacity a percentage value, which actually means RemainingBatteryPercentage. Now we found some battery follows this rule even if it's a rechargeable. https://bugzilla.kernel.org/show_bug.cgi?id=15979 Handle these batteries correctly in ACPI battery driver so that they won't break userspace.

Module level code is the executable AML code outside of control method, for example, below AML code creates a node \_SB.PCI0.GFX0.DD02.CUBL If (\_OSI ("Windows 2006")) { Scope (\_SB.PCI0.GFX0.DD02) { Name (CUBL, Ones) ... } } Scope() op does not actually create a new object, it refers to an existing object(\_SB.PCI0.GFX0.DD02 in above example). However, for Scope(), we want to indeed open a new scope, so the child nodes(CUBL in above example) can be created correctly under it. https://bugzilla.kernel.org/show_bug.cgi?id=19462 Signed-off-by: Bob Moore <robert.moore@intel.com> Signed-off-by: Lin Ming <ming.m.lin@intel.com> Signed-off-by: Len Brown <len.brown@intel.com>

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | IOC3 is also being used on SGI MIPS systems but this particular driver is only being used on IA64 systems so linux-mips made no sense as a list. Pat also thinks linux-serial@vger.kernel.org is the better list. Signed-off-by: Ralf Baechle <ralf@linux-mips.org>

We can get it to descend into the platform directories by setting $(obj-). The dec Platform file was unconditionally setting platform-, obliterating its previous contents and preventing some directories from being cleaned. This is change to an append operation '+=' to allow cavium-octeon to be cleaned.

* | | | | virtio: console: Don't block entire guest if host doesn't read dataAmit Shah2010-10-201-3/+14

To overcome this, let's not block till the host signals it has given back the virtio ring element we passed it. Instead, send the buffer to the host and return to userspace. This operation then becomes similar to how non-blocking writes work, so let's use the existing code for this path as well. This code change also ensures blocking write calls do get blocked if there's not enough room in the virtio ring as well as they don't return -EAGAIN to userspace.
