2009-04-04acer-wmi: Blacklist Acer Aspire OneCarlos Corbacho
The Aspire One's ACPI-WMI interface is a placeholder that does nothing, and the invalid results that we get from it are now causing userspace problems as acer-wmi always returns that the rfkill is enabled (i.e. the radio is off, when it isn't). As it's hardware controlled, acer-wmi isn't needed on the Aspire One either. Thanks to Andy Whitcroft at Canonical for tracking down Ubuntu's userspace issues to this.

2009-04-04thinkpad-acpi: rework brightness supportHenrique de Moraes Holschuh
Refactor and redesign the brightness control backend... In order to fix bugzilla #11750... Add a new brightness control mode: support direct NVRAM checkpointing of the backlight level (i.e. store directly to NVRAM without the need for UCMS calls), and use that together with the EC-based control. Disallow UCMS+EC, thus avoiding races with the SMM firmware. Switch the models that define HBRV (EC Brightness Value) in the DSDT to the new mode. These are: T40-T43, R50-R52, R50e, R51e, X31-X41. Change the default for all other IBM ThinkPads to UCMS-only. The Lenovo models already default to UCMS-only.

2009-04-04thinkpad-acpi: enhanced debugging messages for rfkill subdriversHenrique de Moraes Holschuh
Enhance debugging messages for all rfkill subdrivers in thinkpad-acpi. Also, log a warning if the deprecated sysfs attributes are in use. These attributes are going to be removed sometime in 2010. There is an user-visible side-effect: we now coalesce attempts to enable/disable bluetooth or WWAN in the procfs interface, instead of hammering the firmware with multiple requests.

2009-04-04thinkpad-acpi: restrict access to some firmware LEDsHenrique de Moraes Holschuh
Some of the ThinkPad LEDs indicate critical conditions that can cause data loss or cause hardware damage when ignored (e.g. force-ejecting a powered up bay; ignoring a failing battery, or empty battery; force- undocking with the dock buses still active, etc). On almost all ThinkPads, LED access is write-only, and the firmware usually does fire-and-forget signaling on them, so you effectively lose whatever message the firmware was trying to convey to the user when you override the LED state, without any chance to restore it. Restrict access to all LEDs that can convey important alarms, or that could mislead the user into incorrectly operating the hardware. This will make the Lenovo engineers less unhappy about the whole issue. Allow users that really want it to still control all LEDs, it is the unaware user that we have to worry about.

2009-04-04thinkpad-acpi: remove HKEY disable functionalityHenrique de Moraes Holschuh
The HKEY disable functionality basically cripples the entire event model of the ThinkPad firmware and of the thinkpad-acpi driver. Remove this functionality from the driver. HKEY must be enabled at all times while thinkpad-acpi is loaded, and disabled otherwise. For sysfs, according to the sysfs ABI and the thinkpad-acpi sysfs rules of engagement, we will just remove the attributes. This will be done in two stages: disable their function now, after two kernel releases, remove the attributes. For procfs, we call WARN(). If nothing triggers it, I will simply remove the enable/disable commands entirely in the future along with the sysfs attributes. I don't expect much, if any fallout from this. There really isn't any reason to mess with hotkey_enable or with the enable/disable commands to /proc/acpi/ibm/hotkey, and this has been true for years...

2009-04-04thinkpad-acpi: add new debug helpers and warn of deprecated attsHenrique de Moraes Holschuh
Add a debug helper that discloses the TGID of the userspace task attempting to access the driver. This is highly useful when dealing with bug reports, since often the user has no idea that some userspace application is accessing thinkpad-acpi... Also add a helper to log warnings about sysfs attributes that are deprecated. Use the new helpers to issue deprecation warnings for bluetooth_enable and wwan_enabled, that have been deprecated for a while, now.

2009-04-03tc1100-wmi: Fix state reportingKrzysztof Kosiński
The tc1100-wmi driver should print the current states of wireless LAN and jogdial brightness control when "cat /sys/devices/platform/tc1100-wmi/wireless" and "cat /sys/devices/platform/tc1100-wmi/jogdial" are executed, respectively. What actually happens is that both of those commands print 0 regardless of the hardware state. The cause is that wmi_query_block returns an ACPI_TYPE_INTEGER rather than ACPI_TYPE_BUFFER as the driver assumes. Additionally, the driver intends to return a jogdial state that is inverted with respect to the commands required to set it (e.g. it intends to return 1 after the jogdial file was written with 0). This patch fixes both of those issues - the commands to query the state now work, and should return the same state that was written. http://bugzilla.kernel.org/show_bug.cgi?id=12286 Signed-off-by: Krzysztof Kosiński <tweenk.pl@gmail.com> Acked-by: Carlos Corbacho <carlos@strangeworlds.co.uk> Signed-off-by: Len Brown <len.brown@intel.com>

2009-03-31proc 2/2: remove struct proc_dir_entry::ownerAlexey Dobriyan
Setting ->owner as done currently (pde->owner = THIS_MODULE) is racy as correctly noted at bug #12454. Someone can lookup entry with NULL ->owner, thus not pinning enything, and release it later resulting in module refcount underflow. We can keep ->owner and supply it at registration time like ->proc_fops and ->data. But this leaves ->owner as easy-manipulative field (just one C assignment) and somebody will forget to unpin previous/pin current module when switching ->owner. ->proc_fops is declared as "const" which should give some thoughts. ->read_proc/->write_proc were just fixed to not require ->owner for protection. rmmod'ed directories will be empty and return "." and ".." -- no harm. And directories with tricky enough readdir and lookup shouldn't be modular. We definitely don't want such modular code. Removing ->owner will also make PDE smaller. So, let's nuke it. Kudos to Jeff Layton for reminding about this, let's say, oversight. http://bugzilla.kernel.org/show_bug.cgi?id=12454 Signed-off-by: Alexey Dobriyan <adobriyan@gmail.com>
