2015-02-18x86/intel/quark: Add Isolated Memory Regions for Quark X1000Bryan O'Donoghue
Intel's Quark X1000 SoC contains a set of registers called Isolated Memory Regions. IMRs are accessed over the IOSF mailbox interface. IMRs are areas carved out of memory that define read/write access rights to the various system agents within the Quark system. For a given agent in the system it is possible to specify if that agent may read or write an area of memory defined by an IMR with a granularity of 1 KiB. Quark_SecureBootPRM_330234_001.pdf section 4.5 details the concept of IMRs quark-x1000-datasheet.pdf section 12.7.4 details the implementation of IMRs in silicon. eSRAM flush, CPU Snoop write-only, CPU SMM Mode, CPU non-SMM mode, RMU and PCIe Virtual Channels (VC0 and VC1) can have individual read/write access masks applied to them for a given memory region in Quark X1000. This enables IMRs to treat each memory transaction type listed above on an individual basis and to filter appropriately based on the IMR access mask for the memory region. Quark supports eight IMRs. Since all of the DMA capable SoC components in the X1000 are mapped to VC0 it is possible to define sections of memory as invalid for DMA write operations originating from Ethernet, USB, SD and any other DMA capable south-cluster component on VC0. Similarly it is possible to mark kernel memory as non-SMM mode read/write only or to mark BIOS runtime memory as SMM mode accessible only depending on the particular memory footprint on a given system. On an IMR violation Quark SoC X1000 systems are configured to reset the system, so ensuring that the IMR memory map is consistent with the EFI provided memory map is critical to ensure no IMR violations reset the system. The API for accessing IMRs is based on MTRR code but doesn't provide a /proc or /sys interface to manipulate IMRs. Defining the size and extent of IMRs is exclusively the domain of in-kernel code. Quark firmware sets up a series of locked IMRs around pieces of memory that firmware owns such as ACPI runtime data. During boot a series of unlocked IMRs are placed around items in memory to guarantee no DMA modification of those items can take place. Grub also places an unlocked IMR around the kernel boot params data structure and compressed kernel image. It is necessary for the kernel to tear down all unlocked IMRs in order to ensure that the kernel's view of memory passed via the EFI memory map is consistent with the IMR memory map. Without tearing down all unlocked IMRs on boot transitory IMRs such as those used to protect the compressed kernel image will cause IMR violations and system reboots. The IMR init code tears down all unlocked IMRs and sets a protective IMR around the kernel .text and .rodata as one contiguous block. This sanitizes the IMR memory map with respect to the EFI memory map and protects the read-only portions of the kernel from unwarranted DMA access.

2015-02-11toshiba_acpi: Add support for Keyboard functions modeAzael Avalos
Recent Toshiba laptops that come with the new keyboard layout have the Special Functions (hotkeys) enabled by default, which, in order to access the F{1-12} keys, you need to press the FN-F{1-12} key to access such key. This patch adds support to toggle the Keyboard Functions operation mode by creating the sysfs entry "kbd_functions_keys", accepting only two parameters, 0 to set the "Normal Operation" mode and 1 to set the "Special Functions" mode, however, everytime the mode is toggled, a restart is needed. In the "Normal Operation" mode, the F{1-12} keys are as usual and the hotkeys are accessed via FN-F{1-12}. In the "Special Functions" mode, the F{1-12} keys trigger the hotkey and the F{1-12} keys are accessed via FN-F{1-12}.

2015-02-09toshiba_acpi: Make toshiba_eco_mode_available more robustAzael Avalos
Some Toshiba laptops do not come with the ECO led installed, however, the driver is registering support for it when it should not. This patch makes the toshiba_eco_mode_available function more robust in detecting ECO led capabilities, not registering the led on laptops that do not support it and registering the led when it really does. The ECO led function now returns 0x8e00 (Not Installed) by querying with in[3] = 0, whenever theres no physical LED installed, and returning 0x8300 (Input Data Error) when it is, however, there are some BIOSes that have stub function calls not returning anything and and the LED device was being registered too, hence the change of the default return value from 1 to 0.

2015-02-06samsung-laptop: enable better lid handlingJulijonas Kikutis
Some Samsung laptops with SABI3 delay the sleep for 10 seconds after the lid is closed and do not wake up from sleep after the lid is opened. A SABI command is needed to enable the better behavior. Command = 0x6e, d0 = 0x81 enables this behavior. Returns d0 = 0x01. Command = 0x6e, d0 = 0x80 disables this behavior. Returns d0 = 0x00. Command = 0x6d and any d0 queries the state. This returns: d0 = 0x00000*01, d1 = 0x00, d2 = 0x00, d3 = 0x0* when it is enabled. d0 = 0x00000*00, d1 = 0x00, d2 = 0x00, d3 = 0x0* when it is disabled. Where * is 0 - laptop has never slept or hibernated after switch on, 1 - laptop has hibernated just before, 2 - laptop has slept just before. Patch addresses bug https://bugzilla.kernel.org/show_bug.cgi?id=75901 . It adds a sysfs attribute lid_handling with a description and also an addition to the quirks structure to enable the mode by default. A user with another laptop in the bug report says that "power button has to be pressed twice to wake the machine" when he or she enabled the mode manually using the SABI command. Therefore, it is enabled by default only for the single laptop that I have tested. Signed-off-by: Julijonas Kikutis <julijonas.kikutis@gmail.com> Signed-off-by: Darren Hart <dvhart@linux.intel.com>
2015-01-28toshiba_acpi: Add a check for TOS_NOT_SUPPORTED in the sci_open functionAzael Avalos
This was "toshiba_acpi: Change sci_open function return value" Some Toshiba laptops have "poorly implemented" SCI calls on their BIOSes and are not checking for sci_{open, close} calls, therefore, the sci_open function is failing and making some of the supported features unavailable (kbd backlight, touchpad, illumination, etc.). This patch checks whether we receive TOS_NOT_SUPPORTED and returns 1, making the supported features work on such laptops. In the case that some laptops really do not support the SCI, all the SCI dependent functions check for TOS_NOT_SUPPORTED, and thus, not registering support for the queried feature.

2015-01-23samsung-laptop: Add use_native_backlight quirk, and enable it on some modelsHans de Goede
Since kernel 3.14 the backlight control has been broken on various Samsung Atom based netbooks. This has been bisected and this problem happens since commit b35684b8fa94 ("drm/i915: do full backlight setup at enable time") This has been reported and discussed in detail here: http://lists.freedesktop.org/archives/intel-gfx/2014-July/049395.html Unfortunately no-one has been able to fix this. This only affects Samsung Atom netbooks, and the Linux kernel and the BIOS of those laptops have never worked well together. All affected laptops already have a quirk to avoid using the standard acpi-video interface and instead use the samsung specific SABI interface which samsung-laptop uses. It seems that recent fixes to the i915 driver have also broken backlight control through the SABI interface. The intel_backlight driver OTOH works fine, and also allows for finer grained backlight control. So add a new use_native_backlight quirk, and replace the broken_acpi_video quirk with this quirk for affected models. This new quirk disables acpi-video as before and also stops samsung-laptop from registering the SABI based samsung_laptop backlight interface, leaving only the working intel_backlight interface. This commit enables this new quirk for 3 models which are known to be affected, chances are that it needs to be used on other models too.

thinkpad-acpi: acpi: Remove _OSI(Linux) for ThinkPads thinkpad-acpi: Try to use full software mute control Signed-off-by: Darren Hart <dvhart@linux.intel.com>
2014-12-04thinkpad-acpi: Try to use full software mute controlAndy Lutomirski
ThinkPads have hardware volume controls and three buttons to control them. (These are separate from the standard mixer.) By default, the buttons are: - Mute: Mutes the hardware volume control and, on some models, generates KEY_MUTE. - Up: Unmutes, generates KEY_VOLUMEUP, and increases volume if applicable. (Newer thinkpads only have hardware mute/unmute.) - Down: Unmutes, generates KEY_VOLUMEDOWN, and decreases volume if applicable. This behavior is unfortunate, since modern userspace will also handle the hotkeys and change the other mixer. If the software mixer is muted and the hardware mixer is unmuted and you push mute, hilarity ensues as they both switch state. Rather than adding a lot of complex ALSA integration to fix this, just disable the special ThinkPad volume controls when possible. This turns the mute and volume buttons into regular buttons, and standard software controls will work as expected. ALSA already knows about the mute light on models with a mute light, so everything should just work. This should also allow us to remove _OSI(Linux) for all ThinkPads. For future reference: It turns out that we can ask ACPI for one of three behaviors directly on very new models. They are "latch" (the default), "none" (no automatic control), and "toggle" (mute unmutes when muted). All of the modes besides "none" seem to be a bit buggy, though, and there doesn't seem to be a consistent way to get any notification when the HW mute state is changed.

2014-12-04acerhdf: Use bang-bang thermal governorPeter Feuerer
acerhdf has been doing an on-off fan control using hysteresis by post-manipulating the outcome of thermal subsystem trip point handling. This patch enables acerhdf to use the bang-bang governor, which is intended for on-off controlled fans.

2014-12-03platform: x86: dell-laptop: Add support for keyboard backlightPali Rohár
This patch adds support for configuring keyboard backlight settings on supported Dell laptops. It exports kernel leds interface and uses Dell SMBIOS tokens or keyboard class interface. With this patch it is possible to set: * keyboard backlight level * timeout after which will be backlight automatically turned off * input activity triggers (keyboard, touchpad, mouse) which enable backlight * ambient light settings Settings are exported via sysfs: /sys/class/leds/dell::kbd_backlight/ Code is based on newly released documentation by Dell in libsmbios project. Thanks to Dan Carpenter who reported bug about unpredictable results in quirks->kbd_timeouts for loop. His fix adds needs_kbd_timeouts flag to quirk structure to indicate if kbd_timeouts array is empty or not.

A previous patch added support to handle more events. This patch adds support to update the sysfs group whenever we receive a 0x92 event, which indicates a change in the keyboard backlight mode, removing the update group code from toshiba_kbd_bl_mode_store, as it is no longer needed there.
