2016-08-02w1:omap_hdq: fix regressionH. Nikolaus Schaller1-2/+0
Commit e93762bbf681 ("w1: masters: omap_hdq: add support for 1-wire mode") added a statement to clear the hdq_irqstatus flags in hdq_read_byte(). If the hdq reading process is scheduled slowly or interrupts are disabled for a while the hardware read activity might already be finished on entry of hdq_read_byte(). And hdq_isr() already has set the hdq_irqstatus to 0x6 (can be seen in debug mode) denoting that both, the TXCOMPLETE and RXCOMPLETE interrupts occurred in parallel. This means there is no need to wait and the hdq_read_byte() can just read the byte from the hdq controller. By resetting hdq_irqstatus to 0 the read process is forced to be always waiting again (because the if statement always succeeds) but the hardware will not issue another RXCOMPLETE interrupt. This results in a false timeout. After such a situation the hdq bus hangs. Link: http://lkml.kernel.org/r/b724765f87ad276a69625bc19806c8c8844c4590.1469513669.git.hns@goldelico.com Signed-off-by: H.

2016-08-02rapidio: add RapidIO channelized messaging driverAlexandre Bounine3-0/+2376
Add channelized messaging driver to support native RapidIO messaging exchange between multiple senders/recipients on devices that use kernel RapidIO subsystem services. This device driver is the result of collaboration within the RapidIO.org Software Task Group (STG) between Texas Instruments, Prodrive Technologies, Nokia Networks, BAE and IDT. Additional input was received from other members of RapidIO.org. The objective was to create a character mode driver interface which exposes messaging capabilities of RapidIO endpoint devices (mports) directly to applications, in a manner that allows the numerous and varied RapidIO implementations to interoperate. This char mode device driver allows user-space applications to setup messaging communication channels using single shared RapidIO messaging mailbox. By default this driver uses RapidIO MBOX_1 (MBOX_0 is reserved for use by RIONET Ethernet emulation driver).

2016-08-02firmware: support loading into a pre-allocated bufferStephen Boyd1-26/+99
Some systems are memory constrained but they need to load very large firmwares. The firmware subsystem allows drivers to request this firmware be loaded from the filesystem, but this requires that the entire firmware be loaded into kernel memory first before it's provided to the driver. This can lead to a situation where we map the firmware twice, once to load the firmware into kernel memory and once to copy the firmware into the final resting place. This creates needless memory pressure and delays loading because we have to copy from kernel memory to somewhere else. Let's add a request_firmware_into_buf() API that allows drivers to request firmware be loaded directly into a pre-allocated buffer. This skips the intermediate step of allocating a buffer in kernel memory to hold the firmware image while it's read from the filesystem. It also requires that drivers know how much memory they'll require before requesting the firmware and negates any benefits of firmware caching because the firmware layer doesn't manage the buffer lifetime. For a 16MB buffer, about half the time is spent performing a memcpy from the buffer to the final resting place. I see loading times go from 0.081171 seconds to 0.047696 seconds after applying this patch. Plus the vmalloc pressure is reduced. This is based on a patch from Vikram Mulukutla on codeaurora.org: https://www.codeaurora.org/cgit/quic/la/kernel/msm-3.18/commit/drivers/base/firmware_class.c?h=rel/msm-3.18&id=0a328c5f6cd999f5c591f172216835636f39bcb5 Link: http://lkml.kernel.org/r/20160607164741.31849-4-stephen.boyd@linaro.org Signed-off-by: Stephen Boyd <stephen.boyd@linaro.org> Cc: Mimi Zohar <zohar@linux.vnet.ibm.com> Cc: Vikram Mulukutla <markivx@codeaurora.org> Cc: Mark Brown <broonie@kernel.org> Cc: Ming Lei <ming.lei@canonical.com> Cc: Greg Kroah-Hartman <gregkh@linuxfoundation.org> Signed-off-by: Andrew Morton <akpm@linux-foundation.org> Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>
2016-08-02firmware: provide infrastructure to make fw caching optionalVikram Mulukutla1-2/+5
Some low memory systems with complex peripherals cannot afford to have the relatively large firmware images taking up valuable memory during suspend and resume. Change the internal implementation of firmware_class to disallow caching based on a configurable option. In the near future, variants of request_firmware will take advantage of this feature.

2016-08-02firmware: consolidate kmap/read/write logicStephen Boyd1-31/+26
Some systems are memory constrained but they need to load very large firmwares. The firmware subsystem allows drivers to request this firmware be loaded from the filesystem, but this requires that the entire firmware be loaded into kernel memory first before it's provided to the driver. This can lead to a situation where we map the firmware twice, once to load the firmware into kernel memory and once to copy the firmware into the final resting place. This design creates needless memory pressure and delays loading because we have to copy from kernel memory to somewhere else. This patch sets adds support to the request firmware API to load the firmware directly into a pre-allocated buffer, skipping the intermediate copying step and alleviating memory pressure during firmware loading. The drawback is that we can't use the firmware caching feature because the memory for the firmware cache is not managed by the firmware layer. This patch (of 3): We use similar structured code to read and write the kmapped firmware pages. The only difference is read copies from the kmap region and write copies to it. Consolidate this into one function to reduce duplication.

Handling the wraparound requires the data->last_update to be set to an initial jiffies value. Otherwise on 32-bit systems you will not be able to request a reading till the 5 minute jiffies rollover happens.

ap_configuration is malloced in ap_module_init() and should be freed before leaving from the error handling cases, otherwise it may cause memory leak. Signed-off-by: Wei Yongjun <weiyj.lk@gmail.com> Signed-off-by: Martin Schwidefsky <schwidefsky@de.ibm.com>
2016-07-31s390/zcrypt: Fix zcrypt suspend/resume behaviorIngo Tuchscherer5-6/+47
The device suspend call triggers all ap devices to fetch potentially available response messages from the queues. Therefore the corresponding zcrypt device, that is allocated asynchronously after ap device probing, needs to be fully prepared. This race condition could lead to uninitialized response buffers while trying to read from the queues. Introduce a new callback within the ap layer to get noticed when a zcrypt device is fully prepared. Additional checks prevent reading from devices that are not fully prepared.

2016-07-31s390/cio: fix premature wakeup during chp configureSebastian Ott1-14/+32
We store requests for channel path configure operations in an array but maintain an additional cfg_busy variable (indicating if we have requests stored in said array). When 2 tasks request a channel path configure operation cfg_busy could be set to 0 even if we still have unprocessed requests. This would lead to the second task being woken up although its request was not processed yet. Fix that by getting rid of cfg_busy and use the chp_cfg_task array in the wake up condition.

2016-07-31s390/cio: convert cfg_lock mutex to spinlockSebastian Ott1-9/+9
cfg_lock is never held long and we don't want to sleep while the lock is being held. Thus it can be converted to a simple spinlock. In addition we can now use the lock during the evaluation of a wake_up condition.

git://git.kernel.org/pub/scm/linux/kernel/git/tiwai/sound Pull sound updates from Takashi Iwai: "The majority of this update is about ASoC, including a few new drivers, and the rest are mostly minor changes. The only substantial change in ALSA core is about the additional error handling in the compress-offload API. Below are highlights: - Add the error propagating support in compress-offload API - HD-audio: a usual Dell headset fixup, an Intel HDMI/DP fix, and the default mixer setup change ot turn off the loopback - Lots of updates for ASoC Intel drivers, mostly board support and bug fixing, and to the NAU8825 driver - Work on generalizing bits of simple-card to allow more code sharing with the Renesas rsrc-card (which can't use simple-card due to DPCM) - Removal of the Odroid X2 driver due to replacement with simple-card - Support for several new Mediatek platforms and associated boards - New ASoC drivers for Allwinner A10, Analog Devices ADAU7002, Broadcom Cygnus, Cirrus Logic CS35L33 and CS53L30, Maxim MAX8960 and MAX98504, Realtek RT5514 and Wolfson WM8758" * tag 'sound-4.8-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/tiwai/sound: (278 commits) sound: oss: Use kernel_read_file_from_path() for mod_firmware_load() ASoC: Intel: Skylake: Delete an unnecessary check before the function call "release_firmware" ASoC: Intel: Skylake: Fix NULL Pointer exception in dynamic_debug.
