Seems we all agree that information about SECTION, e.g. section size, sections per memory block should be kept as kernel internals, and not exposed to userspace. This patch updates Documentation/memory-hotplug.txt to refer to memory blocks instead of memory sections where appropriate and added a paragraph to explain that memory blocks are made of memory sections. The documentation update is mostly provided by Nathan. Also, as end_phys_index in code is actually not the end section id, but the end memory block id, which should always be the same as phys_index. So it is removed here.

Currently, "cma=" kernel parameter is used to specify the size of CMA, but we can't specify where it is located. We want to locate CMA below 4GB for devices only supporting 32-bit addressing on 64-bit systems without iommu. This enables to specify the placement of CMA by extending "cma=" kernel parameter. Examples: 1. locate 64MB CMA below 4GB by "cma=64M@0-4G" 2. locate 64MB CMA exact at 512MB by "cma=64M@512M" Note that the DMA contiguous memory allocator on x86 assumes that page_address() works for the pages to allocate. So this change requires to limit end address of contiguous memory area upto max_pfn_mapped to prevent from locating it on highmem area by the argument of dma_contiguous_reserve().

There is no point in calling dev_get_drvdata without a valid device. So checking for dev == NULL is pointless. If such a check is ever needed - which I doubt - the driver should do it before calling dev_get_drvdata. We were returning NULL if dev was NULL, which the caller certainly did not expect anyway, so that was only delaying the crash if the caller is not paying attention.

dma_declare_coherent_memory() takes two addresses for a region of memory: a "bus_addr" and a "device_addr". I think the intent is that "bus_addr" is the physical address a *CPU* would use to access the region, and "device_addr" is the bus address the *device* would use to address the region. Rename "bus_addr" to "phys_addr" and change its type to phys_addr_t. Most callers already supply a phys_addr_t for this argument. The others supply a 32-bit integer (a constant, unsigned int, or __u32) and need no change. Use "unsigned long", not phys_addr_t, to hold PFNs. No functional change (this could theoretically fix a truncation in a config with 32-bit dma_addr_t and 64-bit phys_addr_t, but I don't think there are any such cases involving this code).

Currently, some subsystems (e.g. PCI and the ACPI PM domain) have to resume all runtime-suspended devices during system suspend, mostly because those devices may need to be reprogrammed due to different wakeup settings for system sleep and for runtime PM. For some devices, though, it's OK to remain in runtime suspend throughout a complete system suspend/resume cycle (if the device was in runtime suspend at the start of the cycle). We would like to do this whenever possible, to avoid the overhead of extra power-up and power-down events. However, problems may arise because the device's descendants may require it to be at full power at various points during the cycle. Therefore the most straightforward way to do this safely is if the device and all its descendants can remain runtime suspended until the complete stage of system resume. To this end, introduce a new device PM flag, power.direct_complete and modify the PM core to use that flag as follows. If the ->prepare() callback of a device returns a positive number, the PM core will regard that as an indication that it may leave the device runtime-suspended. It will then check if the system power transition in progress is a suspend (and not hibernation in particular) and if the device is, indeed, runtime-suspended. In that case, the PM core will set the device's power.direct_complete flag. Otherwise it will clear power.direct_complete for the device and it also will later clear it for the device's parent (if there's one). Next, the PM core will not invoke the ->suspend() ->suspend_late(), ->suspend_irq(), ->resume_irq(), ->resume_early(), or ->resume() callbacks for all devices having power.direct_complete set. It will invoke their ->complete() callbacks, however, and those callbacks are then responsible for resuming the devices as appropriate, if necessary. For example, in some cases they may need to queue up runtime resume requests for the devices using pm_request_resume().

由 Nishanth Menon 提交于
CPUFREQ custom functions for OPP (Operating Performance Points) currently exist inside the OPP library. These custom functions currently depend on internal data structures to pick up OPP information to create the cpufreq table. For example, the cpufreq table is created precisely in the same order of how OPP entries are stored inside the list implementation. This kind of tight interdependency is purely artificial since the same functionality can be achieved using the generic OPP functions meant to do the same. This interdependency also limits the independent modification of cpufreq and OPP library. So use the generic dev_pm_opp_find_freq_ceil function that achieves the table organization as we currently use. As a result of this, we dont need to use the internal device_opp structure anymore, and we hence we can switch over to rcu lock instead of the mutex holding the internal list lock. This breaking of dependency on internal data structure imposes no change to usage of these. NOTE: This change is a precursor to moving this cpufreq specific logic out of the generic library into cpufreq.

When the kernel is built with CONFIG_PREEMPT it is possible to reach a state when all modules loaded but some driver still stuck in the deferred list and there is a need for external event to kick the deferred queue to probe these drivers. The issue has been observed on embedded systems with CONFIG_PREEMPT enabled, audio support built as modules and using nfsroot for root filesystem. The following log fragment shows such sequence when all audio modules were loaded but the sound card is not present since the machine driver has failed to probe due to missing dependency during it's probe. The board is am335x-evmsk (McASP<->tlv320aic3106 codec) with davinci-evm machine driver: ... [ 12.615118] davinci-mcasp 4803c000.mcasp: davinci_mcasp_probe: ENTER [ 12.719969] davinci_evm sound.3: davinci_evm_probe: ENTER [ 12.725753] davinci_evm sound.3: davinci_evm_probe: snd_soc_register_card [ 12.753846] davinci-mcasp 4803c000.mcasp: davinci_mcasp_probe: snd_soc_register_component [ 12.922051] davinci-mcasp 4803c000.mcasp: davinci_mcasp_probe: snd_soc_register_component DONE [ 12.950839] davinci_evm sound.3: ASoC: platform (null) not registered [ 12.957898] davinci_evm sound.3: davinci_evm_probe: snd_soc_register_card DONE (-517) [ 13.099026] davinci-mcasp 4803c000.mcasp: Kicking the deferred list [ 13.177838] davinci-mcasp 4803c000.mcasp: really_probe: probe_count = 2 [ 13.194130] davinci_evm sound.3: snd_soc_register_card failed (-517) [ 13.346755] davinci_mcasp_driver_init: LEAVE [ 13.377446] platform sound.3: Driver davinci_evm requests probe deferral [ 13.592527] platform sound.3: really_probe: probe_count = 0 In the log the machine driver enters it's probe at 12.719969 (this point it has been removed from the deferred lists). McASP driver already executing it's probing (since 12.615118). The machine driver tries to construct the sound card (12.950839) but did not found one of the components so it fails. After this McASP driver registers all the ASoC components (the machine driver still in it's probe function after it failed to construct the card) and the deferred work is prepared at 13.099026 (note that this time the machine driver is not in the lists so it is not going to be handled when the work is executing). Lastly the machine driver exit from it's probe and the core places it to the deferred list but there will be no other driver going to load and the deferred queue is not going to be kicked again - till we have external event like connecting USB stick, etc. The proposed solution is to try the deferred queue once more when the last driver is asking for deferring and we had drivers loaded while this last driver was probing. This way we can avoid drivers stuck in the deferred queue.

It's perfectly valid to create irqchips dynamically, so let's fix up the issue by resolving the interrupt resources when platform_get_irq is called. And then we also need to accept the fact that some irqdomains do not exist that early on, and only get initialized later on. So we can make the current WARN_ON into just into a pr_debug(). We still attempt to populate irq resources when we create the devices. This allows current drivers which don't use platform_get_irq to continue to function. Once all drivers are fixed, this code can be removed.

For the following the scenarios using the regmap-mmio, for example: Index CPU Device Endianess flag for values ---------------------------------------------------------- 1 LE LE REGMAP_ENDIAN_DEFAULT/NATIVE 2 LE BE REGMAP_ENDIAN_BIG 3 BE BE REGMAP_ENDIAN_DEFAULT/NATIVE 4 BE LE REGMAP_ENDIAN_LITTLE For one device driver, which will support all the cases above, needs two boolean properties in DT node like: 'big-endian' for case 2 and 'little-endian' for case 4, and for cases 1 and 3 they all will be absent.

Keep all power-domains already enabled by bootloader on, even if no driver has claimed them. This is useful for debug and development, but should not be needed on a platform with proper driver support. Signed-off-by: NTushar Behera <tushar.behera@linaro.org> Signed-off-by: NRafael J.

Since regmap core and mmio have already support for 1/2/8 bytes wide values, so adds support for 1/2/8 bytes wide registers address. Signed-off-by: NXiubo Li <Li.Xiubo@freescale.com> Signed-off-by: NMark Brown <broonie@linaro.org>
