2017-04-18PCI: Add arch_can_pci_mmap_io() on architectures which can mmap() I/O spaceDavid Woodhouse
This is relatively esoteric, and knowing that we don't have it makes life easier in some cases rather than just an eventual -EINVAL from pci_mmap_page_range(). Signed-off-by: David Woodhouse <dwmw@amazon.co.uk> Signed-off-by: Bjorn Helgaas <bhelgaas@google.com>
2017-04-18PCI: Add arch_can_pci_mmap_wc() macroDavid Woodhouse
Most of the almost-identical versions of pci_mmap_page_range() silently ignore the 'write_combine' argument and give uncached mappings. Yet we allow the PCIIOC_WRITE_COMBINE ioctl in /proc/bus/pci, expose the 'resourceX_wc' file in sysfs, and allow an attempted mapping to apparently succeed. To fix this, introduce a macro arch_can_pci_mmap_wc() which indicates whether the platform can do a write-combining mapping. On x86 this ends up being pat_enabled(), while the few other platforms that support it can just set it to a literal '1'.

2017-04-16lightnvm: physical block device (pblk) targetJavier González
This patch introduces pblk, a host-side translation layer for Open-Channel SSDs to expose them like block devices. The translation layer allows data placement decisions, and I/O scheduling to be managed by the host, enabling users to optimize the SSD for their specific workloads. An open-channel SSD has a set of LUNs (parallel units) and a collection of blocks. Each block can be read in any order, but writes must be sequential. Writes may also fail, and if a block requires it, must also be reset before new writes can be applied. To manage the constraints, pblk maintains a logical to physical address (L2P) table, write cache, garbage collection logic, recovery scheme, and logic to rate-limit user I/Os versus garbage collection I/Os. The L2P table is fully-associative and manages sectors at a 4KB granularity. Pblk stores the L2P table in two places, in the out-of-band area of the media and on the last page of a line. In the cause of a power failure, pblk will perform a scan to recover the L2P table. The user data is organized into lines. A line is data striped across blocks and LUNs. The lines enable the host to reduce the amount of metadata to maintain besides the user data and makes it easier to implement RAID or erasure coding in the future. pblk implements multi-tenant support and can be instantiated multiple times on the same drive. Each instance owns a portion of the SSD - both regarding I/O bandwidth and capacity - providing I/O isolation for each case. Finally, pblk also exposes a sysfs interface that allows user-space to peek into the internals of pblk. The interface is available at /dev/block/*/pblk/ where * is the block device name exposed.

2017-04-14[media] v4l: Clearly document interactions between formats, controls and buffersLaurent Pinchart
V4L2 exposes parameters that influence buffers sizes through the format ioctls (VIDIOC_G_FMT, VIDIOC_TRY_FMT, VIDIOC_S_FMT, and possibly VIDIOC_G_SELECTION and VIDIOC_S_SELECTION). Other parameters not part of the format structure may also influence buffer sizes or buffer layout in general. One existing such parameter is rotation, which is implemented by the V4L2_CID_ROTATE control and thus exposed through the V4L2 control ioctls. The interaction between those parameters and buffers is currently only partially specified by the V4L2 API. In particular interactions between controls and buffers isn't specified at all. The behaviour of the VIDIOC_S_FMT and VIDIOC_S_SELECTION ioctls when buffers are allocated is also not fully specified. This patch clearly defines and documents the interactions between formats, selections, controls and buffers. The preparatory discussions for the documentation change considered completely disallowing controls that change the buffer size or layout, in favour of extending the format API with a new ioctl that would bundle those controls with format information. The idea has been rejected, as this would essentially be a restricted version of the upcoming request API that wouldn't bring any additional value. Another option we have considered was to mandate the use of the request API to modify controls that influence buffer size or layout. This has also been rejected on the grounds that requiring the request API to change rotation even when streaming is stopped would significantly complicate implementation of drivers and usage of the V4L2 API for applications. Applications will however be required to use the upcoming request API to change at runtime formats or controls that influence the buffer size or layout, because of the need to synchronize buffers with the formats and controls. Otherwise there would be no way to interpret the content of a buffer correctly.

2017-04-14blk-mq: introduce Kyber multiqueue I/O schedulerOmar Sandoval
The Kyber I/O scheduler is an I/O scheduler for fast devices designed to scale to multiple queues. Users configure only two knobs, the target read and synchronous write latencies, and the scheduler tunes itself to achieve that latency goal. The implementation is based on "tokens", built on top of the scalable bitmap library. Tokens serve as a mechanism for limiting requests. There are two tiers of tokens: queueing tokens and dispatch tokens. A queueing token is required to allocate a request. In fact, these tokens are actually the blk-mq internal scheduler tags, but the scheduler manages the allocation directly in order to implement its policy. Dispatch tokens are device-wide and split up into two scheduling domains: reads vs. writes. Each hardware queue dispatches batches round-robin between the scheduling domains as long as tokens are available for that domain. These tokens can be used as the mechanism to enable various policies. The policy Kyber uses is inspired by active queue management techniques for network routing, similar to blk-wbt. The scheduler monitors latencies and scales the number of dispatch tokens accordingly. Queueing tokens are used to prevent starvation of synchronous requests by asynchronous requests. Various extensions are possible, including better heuristics and ionice support. The new scheduler isn't set as the default yet.

2017-04-14iio: adc: add max1117/max1118/max1119 ADC driverAkinobu Mita
This adds max1117/max1118/max1119 8-bit, dual-channel ADC driver. This new driver uses the zero length spi_transfers with the cs_change flag set and/or the non-zero delay_usecs. 1. The zero length transfer with the spi_transfer.cs_change set is required in order to select CH1. The chip select line must be brought high and low again without transfer. 2. The zero length transfer with the spi_transfer.delay_usecs > 0 is required for waiting the conversion to be complete. The conversion begins with the falling edge of the chip select. During the conversion process, SCLK is ignored. These two usages are unusual. But the spi controller drivers that use a default implementation of transfer_one_message() are likely to work. (I've tested this adc driver with spi-omap2-mcspi and spi-xilinx) On the other hand, some spi controller drivers that have their own transfer_one_message() may not work. But at least for the zero length transfer with delay_usecs > 0, I'm proposing a new testcase for the spi-loopback-test that can test whether the delay_usecs setting has taken effect.
