2014-06-09pvpanic: Set high notifier priorityTakashi Iwai1-0/+1
We've observed the missing pvpanic call at panic, and it turned out that this was blocked by the broken notifier of drm_fb_helper, where scheduling may be called during switching to the fb console. It's fairly difficult to fix the drm_fb problem and a quick fix isn't foreseen, a simpler solution for the missing pvpanic call would be just to call this earlier. In order to assure that, this patch sets a higher priority to pvpanic notifier_block. Once when the issue of drm_fb is resolved, we can remove this priority again.

git://git.kernel.org/pub/scm/linux/kernel/git/rafael/linux-pm into next Pull ACPI and power management updates from Rafael Wysocki: "ACPICA is the leader this time (63 commits), followed by cpufreq (28 commits), devfreq (15 commits), system suspend/hibernation (12 commits), ACPI video and ACPI device enumeration (10 commits each). We have no major new features this time, but there are a few significant changes of how things work. The most visible one will probably be that we are now going to create platform devices rather than PNP devices by default for ACPI device objects with _HID. That was long overdue and will be really necessary to be able to use the same drivers for the same hardware blocks on ACPI and DT-based systems going forward. We're not expecting fallout from this one (as usual), but it's something to watch nevertheless. The second change having a chance to be visible is that ACPI video will now default to using native backlight rather than the ACPI backlight interface which should generally help systems with broken Win8 BIOSes. We're hoping that all problems with the native backlight handling that we had previously have been addressed and we are in a good enough shape to flip the default, but this change should be easy enough to revert if need be. In addition to that, the system suspend core has a new mechanism to allow runtime-suspended devices to stay suspended throughout system suspend/resume transitions if some extra conditions are met (generally, they are related to coordination within device hierarchy). However, enabling this feature requires cooperation from the bus type layer and for now it has only been implemented for the ACPI PM domain (used by ACPI-enumerated platform devices mostly today). Also, the acpidump utility that was previously shipped as a separate tool will now be provided by the upstream ACPICA along with the rest of ACPICA code, which will allow it to be more up to date and better supported, and we have one new cpuidle driver (ARM clps711x). The rest is improvements related to certain specific use cases, cleanups and fixes all over the place. Specifics: - ACPICA update to upstream version 20140424. That includes a number of fixes and improvements related to things like GPE handling, table loading, headers, memory mapping and unmapping, DSDT/SSDT overriding, and the Unload() operator. The acpidump utility from upstream ACPICA is included too. From Bob Moore, Lv Zheng, David Box, David Binderman, and Colin Ian King. - Fixes and cleanups related to ACPI video and backlight interfaces from Hans de Goede. That includes blacklist entries for some new machines and using native backlight by default. - ACPI device enumeration changes to create platform devices rather than PNP devices for ACPI device objects with _HID by default. PNP devices will still be created for the ACPI device object with device IDs corresponding to real PNP devices, so that change should not break things left and right, and we're expecting to see more and more ACPI-enumerated platform devices in the future. From Zhang Rui and Rafael J Wysocki. - Updates for the ACPI LPSS (Low-Power Subsystem) driver allowing it to handle system suspend/resume on Asus T100 correctly. From Heikki Krogerus and Rafael J Wysocki. - PM core update introducing a mechanism to allow runtime-suspended devices to stay suspended over system suspend/resume transitions if certain additional conditions related to coordination within device hierarchy are met. Related PM documentation update and ACPI PM domain support for the new feature. From Rafael J Wysocki. - Fixes and improvements related to the "freeze" sleep state. They affect several places including cpuidle, PM core, ACPI core, and the ACPI battery driver. From Rafael J Wysocki and Zhang Rui. - Miscellaneous fixes and updates of the ACPI core from Aaron Lu, Bjørn Mork, Hanjun Guo, Lan Tianyu, and Rafael J Wysocki. - Fixes and cleanups for the ACPI processor and ACPI PAD (Processor Aggregator Device) drivers from Baoquan He, Manuel Schölling, Tony Camuso, and Toshi Kani. - System suspend/resume optimization in the ACPI battery driver from Lan Tianyu. - OPP (Operating Performance Points) subsystem updates from Chander Kashyap, Mark Brown, and Nishanth Menon. - cpufreq core fixes, updates and cleanups from Srivatsa S Bhat, Stratos Karafotis, and Viresh Kumar. - Updates, fixes and cleanups for the Tegra, powernow-k8, imx6q, s5pv210, nforce2, and powernv cpufreq drivers from Brian Norris, Jingoo Han, Paul Bolle, Philipp Zabel, Stratos Karafotis, and Viresh Kumar. - intel_pstate driver fixes and cleanups from Dirk Brandewie, Doug Smythies, and Stratos Karafotis. - Enabling the big.LITTLE cpufreq driver on arm64 from Mark Brown. - Fix for the cpuidle menu governor from Chander Kashyap. - New ARM clps711x cpuidle driver from Alexander Shiyan. - Hibernate core fixes and cleanups from Chen Gang, Dan Carpenter, Fabian Frederick, Pali Rohár, and Sebastian Capella. - Intel RAPL (Running Average Power Limit) driver updates from Jacob Pan. - PNP subsystem updates from Bjorn Helgaas and Fabian Frederick. - devfreq core updates from Chanwoo Choi and Paul Bolle. - devfreq updates for exynos4 and exynos5 from Chanwoo Choi and Bartlomiej Zolnierkiewicz. - turbostat tool fix from Jean Delvare. - cpupower tool updates from Prarit Bhargava, Ramkumar Ramachandra and Thomas Renninger. - New ACPI ec_access.c tool for poking at the EC in a safe way from Thomas Renninger" * tag 'pm+acpi-3.16-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/rafael/linux-pm: (187 commits) ACPICA: Namespace: Remove _PRP method support. intel_pstate: Improve initial busy calculation intel_pstate: add sample time scaling intel_pstate: Correct rounding in busy calculation intel_pstate: Remove C0 tracking PM / hibernate: fixed typo in comment ACPI: Fix x86 regression related to early mapping size limitation ACPICA: Tables: Add mechanism to control early table checksum verification.

2014-05-20acer-wmi: Switch to acpi_video_unregister_backlightHans de Goede1-1/+1
Switch from acpi_video_unregister(), to acpi_video_unregister_backlight(), so that the hotkeys handler registered by acpi-video stays in place. Since there are no mappings for the atkbd raw codes for the brightness keys used by newer Acer models in /lib/udev/hwdb.d/60-keyboard.hwdb, and since we map the wmi events with a code of KE_IGNORE, we rely on acpi-video to do the hotkey handling for us. For laptops such as the Acer Aspire 5750 which uses intel gfx this works despite us calling acpi_video_unregister() because the following happens: 1) acpi-video module gets loaded (as it is a dependency of acer-wmi and i915) 2) acpi-video does NOT call acpi_video_register() 3) acer-wmi loads (assume it loads before i915), calls acpi_video_dmi_promote_vendor(); which sets ACPI_VIDEO_BACKLIGHT_DMI_VENDOR 4) calls acpi_video_unregister -> not registered, nop 5) i915 loads, calls acpi_video_register 6) acpi_video_register registers the acpi_notifier for the hotkeys, does NOT register a backlight device because of ACPI_VIDEO_BACKLIGHT_DMI_VENDOR But on the Acer Aspire 5750G, which uses nvidia graphics the following happens: 1) acpi-video module gets loaded (as it is a dependency of acer-wmi) 2) acpi-video calls acpi_video_register() 3) acpi_video_register registers the acpi_notifier for the hotkeys, and a backlight device 4) acer-wmi loads, calls acpi_video_dmi_promote_vendor() 5) calls acpi_video_unregister, this unregisters BOTH the acpi_notifier for the hotkeys AND the backlight device And we end up without any handler for the brightness hotkeys. This patch fixes this by switching over to acpi_video_unregister_backlight() which keeps the hotkey handler in place.

2014-04-06x86, acpi: LLVMLinux: Remove nested functions from Thinkpad ACPIBehan Webster1-41/+45
The only real change is passing in event_mask to the formerly nested functions. Otherwise it's just moving around function and macro code. This is the only place in the Linux kernel where nested functions are still in use. Nested functions aren't part of the C standards, and complicate the generated code. Although the Linux Kernel has never set out to be entirely C standard compliant, it is increasingly compliant to the standard which is supported by other compilers such as Clang. The LLVMLinux project is working on being able to compile the Linux kernel with Clang. The use of nested functions blocks this effort.

Hi all, my panasonic cf-51 does no longer react to the suspend and hibernate keys. I cannot tell when this started since I no longer use the machine on a daily basis, but I suspect it started when userspace switched from using /proc/acpi/event to the input layer, wich was quite some time ago ;-) Today I investigated the issue and found that the firmware simply does not generate any event on "key down" for those keys, but only on "key up".

git://git.kernel.org/pub/scm/linux/kernel/git/tiwai/sound Pull sound updates from Takashi Iwai: "There have been lots of changes in ALSA core, HD-audio and ASoC, also most of PCI drivers touched by conversions of printks. All these resulted in a high volume and wide ranged patch sets in this release. Many changes are fairly trivial, but also lots of nice cleanups and refactors. There are a few new drivers, most notably, the Intel Haswell and Baytrail ASoC driver. Core changes: - A bit modernization; embed the device struct into snd_card struct, so that it may be referred from the beginning. A new snd_card_new() function is introduced for that, and all drivers have been converted. - Simplification in the device management code in ALSA core; now managed by a simple priority list instead - Converted many kernel messages to use the standard dev_err() & co; this would be the pretty visible difference, especially for HD-audio. HD-audio: - Conexant codecs use the auto-parser as default now; the old static code still remains in case of regressions. Some old quirks have been rewritten with the fixups for auto-parser. - C-Media codecs also use the auto-parser as default now, too. - A device struct is assigned to each HD-audio codec, and the formerly hwdep attributes are accessible over the codec sysfs, too. hwdep attributes still remain for compatibility. - Split the PCI-specific stuff for HD-audio controller into a separate module, ane make a helper module for the generic controller driver. This is a preliminary change for supporting Tegra HDMI controller in near future, which slipped from 3.15 merge. - Device-specific fixes: mute LED support for Lenovo Ideapad, mic LED fix for HP laptops, more ASUS subwoofer quirks, yet more Dell laptop headset quirks - Make the HD-audio codec response a bit more robust - A few improvements on Realtek ALC282 / 283 about the pop noises - A couple of Intel HDMI fixes ASoC: - Lots of cleanups for enumerations; refactored lots of error prone original codes to use more modern APIs - Elimination of the ASoC level wrappers for I2C and SPI moving us closer to converting to regmap completely and avoiding some randconfig hassle - Provide both manually and transparently locked DAPM APIs rather than a mix of the two fixing some concurrency issues - Start converting CODEC drivers to use separate bus interface drivers rather than having them all in one file helping avoid dependency issues - DPCM support for Intel Haswell and Bay Trail platforms, lots of fixes - Lots of work on improvements for simple-card, DaVinci and the Renesas rcar drivers. - New drivers for Analog Devices ADAU1977, TI PCM512x and parts of the CSR SiRF SoC, TLV320AIC31XXX, Armada 370 DB, Cirrus cs42xx8 - Fixes for the simple-card DAI format DT mess - DT support for a couple more devices. - Use of the tdm_slot mapping in a few drivers Others: - Support of reset_resume callback for improved S4 in USB-audio driver; the device with boot quirks have been little tested, which we need to watch out in this development cycle - Add PM support for ICE1712 driver (finally!); it's still pretty partial support, only for M-Audio devices" * tag 'sound-3.15-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/tiwai/sound: (610 commits) ALSA: ice1712: Add suspend support for M-Audio ICE1712-based cards ALSA: ice1712: add suspend support for ICE1712 chip ALSA: hda - Enable beep for ASUS 1015E ALSA: asihpi: fix some indenting in snd_card_asihpi_pcm_new() ALSA: hda - add headset mic detect quirks for three Dell laptops ASoC: tegra: move AC97 clock handling to the machine driver ASoC: simple-card: Handle many DAI links ASoC: simple-card: Add DT documentation for multi-DAI links ASoC: simple-card: dynamically allocate the DAI link and properties ASoC: imx-ssi: Add .xlate_tdm_slot_mask() support.

git://git.kernel.org/pub/scm/linux/kernel/git/rafael/linux-pm Pull ACPI and power management updates from Rafael Wysocki: "As far as the number of commits goes, the top spot belongs to ACPI this time with cpufreq in the second position and a handful of PM core, PNP and cpuidle updates. They are fixes and cleanups mostly, as usual, with a couple of new features in the mix. The most visible change is probably that we will create struct acpi_device objects (visible in sysfs) for all devices represented in the ACPI tables regardless of their status and there will be a new sysfs attribute under those objects allowing user space to check that status via _STA. Consequently, ACPI device eject or generally hot-removal will not delete those objects, unless the table containing the corresponding namespace nodes is unloaded, which is extremely rare. Also ACPI container hotplug will be handled quite a bit differently and cpufreq will support CPU boost ("turbo") generically and not only in the acpi-cpufreq driver. Specifics: - ACPI core changes to make it create a struct acpi_device object for every device represented in the ACPI tables during all namespace scans regardless of the current status of that device. In accordance with this, ACPI hotplug operations will not delete those objects, unless the underlying ACPI tables go away. - On top of the above, new sysfs attribute for ACPI device objects allowing user space to check device status by triggering the execution of _STA for its ACPI object. From Srinivas Pandruvada. - ACPI core hotplug changes reducing code duplication, integrating the PCI root hotplug with the core and reworking container hotplug. - ACPI core simplifications making it use ACPI_COMPANION() in the code "glueing" ACPI device objects to "physical" devices. - ACPICA update to upstream version 20131218. This adds support for the DBG2 and PCCT tables to ACPICA, fixes some bugs and improves debug facilities. From Bob Moore, Lv Zheng and Betty Dall. - Init code change to carry out the early ACPI initialization earlier. That should allow us to use ACPI during the timekeeping initialization and possibly to simplify the EFI initialization too. From Chun-Yi Lee. - Clenups of the inclusions of ACPI headers in many places all over from Lv Zheng and Rashika Kheria (work in progress). - New helper for ACPI _DSM execution and rework of the code in drivers that uses _DSM to execute it via the new helper. From Jiang Liu. - New Win8 OSI blacklist entries from Takashi Iwai. - Assorted ACPI fixes and cleanups from Al Stone, Emil Goode, Hanjun Guo, Lan Tianyu, Masanari Iida, Oliver Neukum, Prarit Bhargava, Rashika Kheria, Tang Chen, Zhang Rui. - intel_pstate driver updates, including proper Baytrail support, from Dirk Brandewie and intel_pstate documentation from Ramkumar Ramachandra. - Generic CPU boost ("turbo") support for cpufreq from Lukasz Majewski. - powernow-k6 cpufreq driver fixes from Mikulas Patocka. - cpufreq core fixes and cleanups from Viresh Kumar, Jane Li, Mark Brown. - Assorted cpufreq drivers fixes and cleanups from Anson Huang, John Tobias, Paul Bolle, Paul Walmsley, Sachin Kamat, Shawn Guo, Viresh Kumar. - cpuidle cleanups from Bartlomiej Zolnierkiewicz. - Support for hibernation APM events from Bin Shi. - Hibernation fix to avoid bringing up nonboot CPUs with ACPI EC disabled during thaw transitions from Bjørn Mork. - PM core fixes and cleanups from Ben Dooks, Leonardo Potenza, Ulf Hansson. - PNP subsystem fixes and cleanups from Dmitry Torokhov, Levente Kurusa, Rashika Kheria. - New tool for profiling system suspend from Todd E Brandt and a cpupower tool cleanup from One Thousand Gnomes" * tag 'pm+acpi-3.14-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/rafael/linux-pm: (153 commits) thermal: exynos: boost: Automatic enable/disable of BOOST feature (at Exynos4412) cpufreq: exynos4x12: Change L0 driver data to CPUFREQ_BOOST_FREQ Documentation: cpufreq / boost: Update BOOST documentation cpufreq: exynos: Extend Exynos cpufreq driver to support boost cpufreq / boost: Kconfig: Support for software-managed BOOST acpi-cpufreq: Adjust the code to use the common boost attribute cpufreq: Add boost frequency support in core intel_pstate: Add trace point to report internal state. cpufreq: introduce cpufreq_generic_get() routine ARM: SA1100: Create dummy clk_get_rate() to avoid build failures cpufreq: stats: create sysfs entries when cpufreq_stats is a module cpufreq: stats: free table and remove sysfs entry in a single routine cpufreq: stats: remove hotplug notifiers cpufreq: stats: handle cpufreq_unregister_driver() and suspend/resume properly cpufreq: speedstep: remove unused speedstep_get_state platform: introduce OF style 'modalias' support for platform bus PM / tools: new tool for suspend/resume performance optimization ACPI: fix module autoloading for ACPI enumerated devices ACPI: add module autoloading support for ACPI enumerated devices ACPI: fix create_modalias() return value handling ...
