2014-11-11bcma: get IRQ numbers from dtHauke Mehrtens
It is not possible to auto detect the irq numbers used by the cores on an arm SoC. If bcma was registered with device tree it will search for some device tree nodes with the irq number and add it to the core configuration.

2014-11-11net: Convert LIMIT_NETDEBUG to net_dbg_ratelimitedJoe Perches
Use the more common dynamic_debug capable net_dbg_ratelimited and remove the LIMIT_NETDEBUG macro. All messages are still ratelimited. Some KERN_<LEVEL> uses are changed to KERN_DEBUG. This may have some negative impact on messages that were emitted at KERN_INFO that are not not enabled at all unless DEBUG is defined or dynamic_debug is enabled. Even so, these messages are now _not_ emitted by default. This also eliminates the use of the net_msg_warn sysctl "/proc/sys/net/core/warnings". For backward compatibility, the sysctl is not removed, but it has no function. The extern declaration of net_msg_warn is removed from sock.h and made static in net/core/sysctl_net_core.c Miscellanea: o Update the sysctl documentation o Remove the embedded uses of pr_fmt o Coalesce format fragments o Realign arguments Signed-off-by: Joe Perches <joe@perches.com> Signed-off-by: David S.

2014-11-10dm cache policy mq: simplify ability to promote sequential IO to the cacheMike Snitzer
Before, if the user wanted sequential IO to be promoted to the cache they'd have to set sequential_threshold to some nebulous large value. Now, the user may easily disable sequential IO detection (and sequential IO's implicit bypass of the cache) by setting sequential_threshold to 0. Signed-off-by: Mike Snitzer <snitzer@redhat.com>
2014-11-10dm cache policy mq: tweak algorithm that decides when to promote a blockJoe Thornber
Rather than maintaining a separate promote_threshold variable that we periodically update we now use the hit count of the oldest clean block. Also add a fudge factor to discourage demoting dirty blocks. With some tests this has a sizeable difference, because the old code was too eager to demote blocks. For example, device-mapper-test-suite's git_extract_cache_quick test goes from taking 190 seconds, to 142 (linear on spindle takes 250).

git://anongit.freedesktop.org/drm-intel into drm-next So here's my atomic series, finally all debugged&reviewed. Sean Paul has done a full detailed pass over it all, and a lot of other people have commented and provided feedback on some parts. Rob Clark also converted msm over the w/e and seems happy. The only small thing is that Rob wants to export the wait_for_vblank, which imo makes sense. Since there's other stuff still to do I think we should apply Rob's patch (once it has grown appropriate kerneldoc) later on top of this. This is just the core<->driver interface plus a big pile of helpers. Short recap of the main ideas: - There are essentially three helper libraries in this patch set: * Transitional helpers to use the new plane callbacks for legacy plane updates and in the crtc helper's ->mode_set callback. These helpers are only temporarily used to convert drivers to atomic, but they allow a nice separation between changing the driver backend and switching to the atomic commit logic. * Legacy helpers to implement all the legacy driver entry points (page_flip, set_config, plane vfuncs) on top of the new atomic driver interface. These are completely driver agnostic. The reason for having the legacy support as helpers is that drivers can switch step-by-step. And they could e.g. even keep the legacy page_flip code around for some old platforms where converting to full-blown atomic isn't worth it. * Atomic helpers which implement the various new ->atomic_* driver interfaces in terms of the revised crtc helper and new plane helper hooks. - The revised crtc helper implemenation essentially implements all the lessons learned in the i915 modeset rework (when using the atomic helpers only): * Enable/disable sequence for a given config are always the same and callbacks are always called in the same order. This contrast starkly with the crtc helpers, where the sequence of operations is heavily dependent on the previous config. One corollary of this is that if the configuration of a crtc only partially changes (e.g. a connector moves in a cloned config) the helper code will still disable/enable the full display pipeline. This is the only way to ensure that the enable/disable sequence is always the same. * It won't call disable or enable hooks more than once any more because it lost track of state, thanks to the atomic state tracking. And if drivers implement the ->reset hook properly (by either resetting the hw or reading out the hw state into the atomic structures) this even extends to the hardware state. So no more disable-me-harder kind of nonsense. * The only thing missing is the hw state readout/cross-check support, but if drivers have hw state readout support in their ->reset handlers it's simple to extend that to cross-check the hw state. * The crtc->mode_set callback is gone and its replacement only sets crtc timings and no longer updates the primary plane state. This way we can finally implement primary planes properly. - The new plane helpers should be suitable enough for pretty much everything, and a perfect fit for hardware with GO bits. Even if they don't fit the atomic helper library is rather flexible and exports all the functions for the individual steps to drivers. So drivers can pick what matches and implement their own magic for everything else. - A big difference compared to all previous atomic series is that this one doesn't implement async commit in a generic way. Imo driver requirements for that are too diverse to create anything reasonable sane which would actually work on a reasonable amount of different drivers. Also, we've never had a helper library for page_flips even, so it's really hard to know what might work and what's stupid without a bit of experience in the form of a few driver implementations. I think with the current flexibility for drivers to pick individual stages and existing helpers like drm_flip_queue it's rather easy though to implement proper async commit. - There's a few other differences of minor importance to earlier atomic series: * Common/generic properties are parsed in the callers/core and not in drivers, and passed to drivers by directly setting the right members in atomic state structures. That greatly simplifies all the transitional and legacy helpers an removes a lot of boilerplate code. * There's no crazy trylock mode used for the async commit since these helpers don't do async commit. A simple ordered flip queue of atomic state updates should be sufficient for preventing concurrent hw access anyway, as long as synchronous updates stall correctly with e.g. flush_work_queue or similar function. Abusing locks to enforce ordering isn't a good idea imo anyway. * These helpers reuse the existing ->mode_fixup hooks in the atomic_check callback. Which means that drivers need to adapat and move a lot less code into their atomic_check callbacks. Now this isn't everything needed in the drm core and helpers for full atomic support. But it's enough to start with converting drivers, and except for actually testing multiplane and multicrtc updates also enough to implement full atomic updates. Still missing are: - Per-plane locking. Since these helpers here encapsulate the locking completely this should be fairly easy to implement. - fbdev support for atomic_check/commit, so that multi-pipe finally works sanely in fbcon. - Adding and decoding shared/core properties. That just needs to be rebased from Rob's latest patch series, with minor adjustments so that the decoding happens in the core instead of in drivers. - Actually adding the atomic ioctl. Again just rebasing Rob's latest patch should be all that's needed. - Resolving how to deal with DPMS in atomic. Atomic is a good excuse to fix up the crazy semantics dpms currently has. I'm floating an RFC about this topic already. - Finally I couldn't test connector/encoder stealing properly since my test vehicle here doesn't allow a connector on different crtcs. So drivers which support this might see some surprises in that area. There is no semantic change though in how encoder stealing and assignment works (or at least no intended one), so I think the risk is minimal. As just mentioned I've done a fake conversion of an existing driver using crtc helpers to debug the helper code and validate the smooth transition approach. And that smooth transition was the really big motivation for this. It seems to actually work and consists of 3 phases: Phase 1: Rework driver backend for crtc/plane helpers The requirement here is that universal plane support is already implement. If universal plane support isn't implement yet it might be better though to just do it as part of this phase, directly using the new plane helpers. There are two big things to do: - Split up the existing ->update/disable_plane hooks into check/commit hooks and extract the crtc-wide prep/flush parts (like setting/clearing GO bits). - The other big change is to split the crtc->mode_set hook into the plane update (done using the plane helpers) and the crtc setup in a new ->mode_set_nofb hook. When phase 1 is complete the driver implements all the new callbacks which push the software state into hardware, but still using all the legacy entry points and crtc helpers. The transitional helpers serve as impendance mismatch here. Phase 2: Rework state handling This consists of rolling out the state handling helpers for planes, crtcs and connectors and reviewing all ->mode_fixup and similar hooks to make sure they don't depend upon implicit global state which might change in the atomic world. Any such code must be moved into ->atomic_check functions which just rely on the free-standing atomic state update structures. This phase also adds a few small pieces of fixup code to make sure the atomic state doesn't get out of sync in the legacy driver callbacks. Phase 3: Roll out atomic support Now it's just about replacing vfuncs with the ones provided by the helper and filling out the small missing pieces (like atomic_check logic or async commit support needed for page_flips). Due to the prep work in phase 1 no changes to the driver backend functions should be required, and because of the prep work in phase 2 atomic implementations can be rolled out step-by-step. So if async commit ins't implemented yet page_flip can be implemented with the legacy functions without wreaking havoc in the other operations. * tag 'topic/atomic-helpers-2014-11-09' of git://anongit.freedesktop.org/drm-intel: drm/atomic: Refcounting for plane_state->fb drm: Docbook integration and over sections for all the new helpers drm/atomic-helpers: functions for state duplicate/destroy/reset drm/atomic-helper: implement ->page_flip drm/atomic-helpers: document how to implement async commit drm/atomic: Integrate fence support drm/atomic-helper: implementatations for legacy interfaces drm: Atomic crtc/connector updates using crtc/plane helper interfaces drm/crtc-helper: Transitional functions using atomic plane helpers drm/plane-helper: transitional atomic plane helpers drm: Add atomic/plane helpers drm: Global atomic state handling drm: Add atomic driver interface definitions for objects drm/modeset_lock: document trylock_only in kerneldoc drm: fixup kerneldoc in drm_crtc.h drm: Pull drm_crtc.h into the kerneldoc template drm: Move drm_crtc_init from drm_crtc.h to drm_plane_helper.h

2014-11-09irqchip: bcm7120-l2: Extend driver to support 64+ bit controllersKevin Cernekee
Most implementations of the bcm7120-l2 controller only have a single 32-bit enable word + 32-bit status word. But some instances have added more enable/status pairs in order to support 64+ IRQs (which are all ORed into one parent IRQ input). Make the following changes to allow the driver to support this: - Extend DT bindings so that multiple words can be specified for the reg property, various masks, etc. - Add loops to the probe/handle functions to deal with each word separately - Allocate 1 generic-chip for every 32 IRQs, so we can still use the clr/set helper functions - Update the documentation This uses one domain per bcm7120-l2 DT node. If the DT node defines multiple enable/status pairs (i.e. >=64 IRQs) then the driver will create a single IRQ domain with 2+ generic chips. Multiple generic chips are required because the generic-chip code can only handle one enable/status register pair per instance.

2014-11-07drivers: base: support cpu cache information interface to userspace via sysfsSudeep Holla
This patch adds initial support for providing processor cache information to userspace through sysfs interface. This is based on already existing implementations(x86, ia64, s390 and powerpc) and hence the interface is intended to be fully compatible. The main purpose of this generic support is to avoid further code duplication to support new architectures and also to unify all the existing different implementations. This implementation maintains the hierarchy of cache objects which reflects the system's cache topology. Cache devices are instantiated as needed as CPUs come online. The cache information is replicated per-cpu even if they are shared. A per-cpu array of cache information maintained is used mainly for sysfs-related book keeping. It also implements the shared_cpu_map attribute, which is essential for enabling both kernel and user-space to discover the system's overall cache topology. This patch also add the missing ABI documentation for the cacheinfo sysfs interface already, which is well defined and widely used.

2014-11-07ASoC: samsung: add support for exynos7 I2S controllerPadmavathi Venna
Exynos7 I2S controller has no internal dma, supports more no. of root clock sampling frequencies and has more no.of Rx fifos to support 7.1CH recording in TDM mode. Due to more no. of root clock frequency values some of the bit offsets got shifted up by one. Also I2S1 on previous Samsung platforms uses v3 dai type but on Exynos7 it is upgraded to v5 with slightly modified register offsets for supporting more no.of RFS values. Due to the above changes, the driver has to be modified to handle all versions of I2S controller. For this I introduced a new structure to hold modified bit offsets and masks which is passed as dai data.

2014-11-06serial: mxs-auart: use mctrl_gpio helpers for handling modem signalsJanusz Uzycki
Dedicated CTS and RTS pins are unusable together with a lot of other peripherals because they share the same line. Pinctrl is limited. Moreover, the AUART controller doesn't handle DTR/DSR/DCD/RI signals, so we have to control them via GPIO. This patch permits to use GPIOs to control the CTS/RTS/DTR/DSR/DCD/RI signals.

2014-11-06PCI: Allow numa_node override via sysfsPrarit Bhargava
NUMA systems with ACPI normally describe the physical topology via _PXM methods. But many BIOSes don't implement _PXM, which leaves the kernel with no way to discover the device topology, which reduces performance because we can't put memory and processes close to the device. The NUMA node of a PCI device is already exported in the sysfs "numa_node" file. Make that file writable so users can workaround the lack of _PXM methods in the BIOS. For example: echo 3 > /sys/devices/pci0000:ff/0000:03:1f.3/numa_node sets the node for PCI device 0000:03:1f.3. Writing the file emits a FW_BUG warning to encourage users to request firmware updates. It also taints the kernel with TAINT_FIRMWARE_WORKAROUND because overriding the node incorrectly can cause performance issues.
