2010-12-06wmi: use memcmp instead of strncmp to compare GUIDsThadeu Lima de Souza Cascardo1-1/+1
While looking for the duplicates in /sys/class/wmi/, I couldn't find them. The code that looks for duplicates uses strncmp in a binary GUID, which may contain zero bytes. The right function is memcmp, which is also used in another section of wmi code. It was finding 49142400-C6A3-40FA-BADB-8A2652834100 as a duplicate of 39142400-C6A3-40FA-BADB-8A2652834100. Since the first byte is the fourth printed, they were found as equal by strncmp.

2010-11-24asus-laptop: add wimax and wwan supportCorentin Chary1-1/+96
Asus UL30A has a 3G chip, but the radio is disabled by default. The DSDT also reference a WIMAX device, which is not present on this model. This patch adds two new files: wwan and wimax to control WWAN and WIMAX devices. It does not use rfkill, because like WLED and BLED, we don't know yet that the two ACPI functions will always control the radio, they may control only the leds on some hardware. We may add rfkill switchs later. Signed-off-by: Corentin Chary <corentincj@iksaif.net> Signed-off-by: Matthew Garrett <mjg@redhat.com>

Some of the IBM servers that are supported by ibm_rtl can run in both Legacy mode (BIOS) and in UEFI mode.

2010-10-21eeepc-wmi: Add cpufv sysfs interfaceChris Bagwell1-0/+51
eeepc-laptop provides a sysfs interface to read and control what it calls cpufv. When WMI is enabled, the ACPI interface changes slightly and becames a write-only control with 3 valid values. Expose cpufv again to allow for user space utils that can extended battery life noticably and come a little closer to parity with eeepc-laptop. Write-only is OK for most user space apps because read status was mostly used to prevent unneeded mode changes. Since this same check to ignore changes to same mode also exists in the DSDT then it was wasted ACPI call. acpi_osi="!Windows 2009" can be used for get back eeepc-laptop's read support of cpufv for debugging things such as behaviour during resume. This patch was tested with EEE PC 1005PE by monitoring powertop output while writing values of "0", "1", and "2" and by reviewing the decompiled DSDT of an 1201NL and comparing it to 1005PE's DSDT.

These were tested on 1005PE and are the Fn-F3, F4, F7, and F9, respectively. Also, added a new hot key for power toggles (Fn-Space on 1005PE) and is meant to drive cpufv interface from userspace.

2010-10-21panasonic-laptop: Simplify calls to acpi_pcc_retrieve_biosdataJean Delvare1-10/+10
Function acpi_pcc_retrieve_biosdata is always called with parameters (pcc, pcc->sinf), so we can drop the second parameter. It was dangerous to pass the sinf array separately anyway, as its length is checked as pcc->num_sifr, which pretty much assumed it was pcc->sinf (or at least had the same size.) This change makes the code slightly more compact and thus marginally faster.

2010-10-21panasonic-laptop: Handle errors properly if they happenJean Delvare1-0/+2
acpi_pcc_retrieve_biosdata() returns success instead of error if HKEY.SINF is invalid. Fix this. Furthermore, if acpi_pcc_retrieve_biosdata() returns an error during device addition, initialization is properly reverted but value 0 is returned, which means success. This would cause a crash when later using or removing the device, so fix this too.

2010-10-21IBM Real-Time "SMI Free" mode driver -v7Vernon Mauery3-1/+358
After a period of RFC for this driver, I think it is ready for inclusion in the platform-driver-x86 tree, hopefully to be staged in the next merge window into Linus's tree. --Vernon ------------------------------------------------------------ IBM Real-Time "SMI Free" mode driver This driver supports the Real-Time Linux (RTL) BIOS feature. The RTL feature allows non-fatal System Management Interrupts (SMIs) to be disabled on supported IBM platforms and is intended to be coupled with a user-space daemon to monitor the hardware in a way that can be prioritized and scheduled to better suit the requirements for the system. The Device is presented as a special "_RTL_" table to the OS in the Extended BIOS Data Area. There is a simple protocol for entering and exiting the mode at runtime. This driver creates a simple sysfs interface to allow a simple entry and exit from RTL mode in the UFI/BIOS. Since the driver is specific to IBM SystemX hardware (x86- based servers) it only builds on x86 builds. To reduce the risk of loading on the wrong hardware, the module uses DMI information and checks a list of servers that are known to work.

Add new module parameter that force module not to register bluetooth rfkill. There is report that saying using this bluetooth rfkill to enable/disable bluetooth will let bluetooth device initial failed when enable on Lenovo ideapad S12. Fortunately there is another rfkill registered by bluetooth driver for S12 and user can shutdown the bluetooth by either bluetooth driver or HW RF switch. For dual OS user, it may have some trouble that using Linux after turning off bluetooth with another OS if we do not register bluetooth rfkill at all. So we will force bluetooth enable when no_bt_rfkill=1.
