* drm: Introduce drm_fb_helper_prepare()Thierry Reding2014-07-081-1/+2
| | | | | | | | | | | | | | | | | | | | | To implement hotplug detection in a race-free manner, drivers must call drm_kms_helper_poll_init() before hotplug events can be triggered. Such events can be triggered right after any of the encoders or connectors are initialized. At the same time, if the drm_fb_helper_hotplug_event() helper is used by a driver, then the poll helper requires some parts of the FB helper to be initialized to prevent a crash. At the same time, drm_fb_helper_init() requires information that is not necessarily available at such an early stage (number of CRTCs and connectors), so it cannot be used yet. Add a new helper, drm_fb_helper_prepare(), that initializes the bare minimum needed to allow drm_kms_helper_poll_init() to execute and any subsequent hotplug events to be processed properly.

| * drm/gem: remove misleading gfp parameter to get_pages()David Herrmann2014-07-081-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | drm_gem_get_pages() currently allows passing a 'gfp' parameter that is passed to shmem combined with mapping_gfp_mask(). Given that the default mapping_gfp_mask() is GFP_HIGHUSER, it is _very_ unlikely that anyone will ever make use of that parameter. In fact, all drivers currently pass redundant flags or 0. This patch removes the 'gfp' parameter. The only reason to keep it is to remove flags like __GFP_WAIT. But in its current form, it can only be used to add flags. So to remove __GFP_WAIT, you'd have to drop it from the mapping_gfp_mask, which again is stupid as this mask is used by shmem-core for other allocations, too. If any driver ever requires that parameter, we can introduce a new helper that takes the raw 'gfp' parameter. The caller'd be responsible to combine it with mapping_gfp_mask() in a suitable way. The current drm_gem_get_pages() helper would then simply use mapping_gfp_mask() and call the new helper. This is what shmem_read_mapping_pages{_gfp,} does right now. Moreover, the gfp-zone flag-usage is not obvious: If you pass a modified zone, shmem core will WARN() or even BUG(). In other words, the following must be true for 'gfp' passed to shmem_read_mapping_pages_gfp(): gfp_zone(mapping_gfp_mask(mapping)) == gfp_zone(gfp) Add a comment to drm_gem_read_pages() explaining that constraint.

Now since this is init code locking is fairly redudant if it wouldn't be for the drm core registering sysfs files a bit early. And the locking WARNINGs nicely enforce that indeed all access to the mode lists are properly protected. And a full audit shows that only i915 and gma500 touch the modes lists at init time. Hence I've opted to wrap up this entire mode detection sequence for fixed panels with the mode_config mutex for both lvds and edp outputs.

There are a few relatively fresh commits in it, but they are mostly fixes and simple cleanups. ACPI took the lead this time, both in terms of the number of commits and the number of modified lines of code, cpufreq follows and there are a few changes in the PM core and in cpuidle too. A new feature that already got some LWN.net's attention is the device PM QoS extension allowing latency tolerance requirements to be propagated from leaf devices to their ancestors with hardware interfaces for specifying latency tolerance. That should help systems with hardware-driven power management to avoid going too far with it in cases when there are latency tolerance constraints. There also are some significant changes in the ACPI core related to the way in which hotplug notifications are handled. They affect PCI hotplug (ACPIPHP) and the ACPI dock station code too. The bottom line is that all those notification now go through the root notify handler and are propagated to the interested subsystems by means of callbacks instead of having to install a notify handler for each device object that we can potentially get hotplug notifications for. In addition to that ACPICA will now advertise "Windows 2013" compatibility for _OSI, because some systems out there don't work correctly if that is not done (some of them don't even boot). On the system suspend side of things, all of the device suspend and resume callbacks, except for ->prepare() and ->complete(), are now going to be executed asynchronously as that turns out to speed up system suspend and resume on some platforms quite significantly and we have a few more optimizations in that area. Apart from that, there are some new device IDs and fixes and cleanups all over. In particular, the system suspend and resume handling by cpufreq should be improved and the cpuidle menu governor should be a bit more robust now. Specifics: - Device PM QoS support for latency tolerance constraints on systems with hardware interfaces allowing such constraints to be specified. That is necessary to prevent hardware-driven power management from becoming overly aggressive on some systems and to prevent power management features leading to excessive latencies from being used in some cases. - Consolidation of the handling of ACPI hotplug notifications for device objects. This causes all device hotplug notifications to go through the root notify handler (that was executed for all of them anyway before) that propagates them to individual subsystems, if necessary, by executing callbacks provided by those subsystems (those callbacks are associated with struct acpi_device objects during device enumeration). As a result, the code in question becomes both smaller in size and more straightforward and all of those changes should not affect users. - ACPICA update, including fixes related to the handling of _PRT in cases when it is broken and the addition of "Windows 2013" to the list of supported "features" for _OSI (which is necessary to support systems that work incorrectly or don't even boot without it).

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 ...
| * | ACPI / i915: Fix incorrect <acpi/acpi.h> inclusions via <linux/acpi_io.h>Lv Zheng2013-12-071-1/+0
| |/ | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | To avoid build problems and breaking dependencies between ACPI header files, <acpi/acpi.h> should not be included directly by code outside of the ACPI core subsystem. However, that is possible if <linux/acpi_io.h> is included, because that file contains a direct inclusion of <acpi/acpi.h>. For this reason, remove the direct <acpi/acpi.h> inclusion from <linux/acpi_io.h>, move that file from include/linux/ to include/acpi/ and make <linux/acpi.h> include it for CONFIG_ACPI set along with the other ACPI header files. Accordingly, Remove the inclusions of <linux/acpi_io.h> from everywhere. Of course, that causes the contents of the new <acpi/acpi_io.h> file to be available for CONFIG_ACPI set only, so intel_opregion.o that depends on it should also depend on CONFIG_ACPI (and it really should not be compiled for CONFIG_ACPI unset anyway).
