2015-06-11NFC: nci: add generic uart supportVincent Cuissard
Some NFC controller supports UART as host interface. As with SPI, a lot of code can be shared between vendor drivers. This patch add the generic support of UART and provides some extension API for vendor specific needs. This code is strongly inspired by the Bluetooth HCI ldisc implementation. NCI UART vendor drivers will have to register themselves to this layer via nci_uart_register. Underlying tty will have to be configured from user land thanks to an ioctl.

By trial-and-error I found that these are connected to the two keys named "power" and "home" on the motherboard. Register the GPIO block and these two keys in the device tree using the PL061 GPIO driver and the generic gpio keys. - Map POWER, HOME, VOL+ and VOL- to the obvious input events. - Map RLOCK to KEY_SCREENLOCK/KEY_COFFEE unless someone can explain better what this is for. - Map the NMI button to KEY_SYSREQ as this is used like so in the SYSREQ debugging hack.

2015-06-11dm thin: range discard supportJoe Thornber
Previously REQ_DISCARD bios have been split into block sized chunks before submission to the thin target. There are a couple of issues with this: - If the block size is small, a large discard request can get broken up into a great many bios which is both slow and causes a lot of memory pressure. - The thin pool block size and the discard granularity for the underlying data device need to be compatible if we want to passdown the discard. This patch relaxes the block size granularity for thin devices. It makes use of the recent range locking added to the bio_prison to quiesce a whole range of thin blocks before unmapping them. Once a thin range has been unmapped the discard can then be passed down to the data device for those sub ranges where the data blocks are no longer used (ie. they weren't shared in the first place). This patch also doesn't make any apologies about open-coding portions of block core as a means to supporting async discard completions in the near-term -- if/when late bio splitting lands it'll all get cleaned up.

2015-06-11dm cache: age and write back cache entries even without active IOJoe Thornber
The policy tick() method is normally called from interrupt context. Both the mq and smq policies do some bottom half work for the tick method in their map functions. However if no IO is going through the cache, then that bottom half work doesn't occur. With these policies this means recently hit entries do not age and do not get written back as early as we'd like. Fix this by introducing a new 'can_block' parameter to the tick() method. When this is set the bottom half work occurs immediately. 'can_block' is set when the tick method is called every second by the core target (not in interrupt context).

2015-06-11dm cache: add fail io mode and needs_check flagJoe Thornber
If a cache metadata operation fails (e.g. transaction commit) the cache's metadata device will abort the current transaction, set a new needs_check flag, and the cache will transition to "read-only" mode. If aborting the transaction or setting the needs_check flag fails the cache will transition to "fail-io" mode. Once needs_check is set the cache device will not be allowed to activate. Activation requires write access to metadata. Future work is needed to add proper support for running the cache in read-only mode. Once in fail-io mode the cache will report a status of "Fail". Also, add commit() wrapper that will disallow commits if in read_only or fail mode. Signed-off-by: Joe Thornber <ejt@redhat.com> Signed-off-by: Mike Snitzer <snitzer@redhat.com>

2015-06-11dm cache: add stochastic-multi-queue (smq) policyJoe Thornber
The stochastic-multi-queue (smq) policy addresses some of the problems with the current multiqueue (mq) policy. Memory usage ------------ The mq policy uses a lot of memory; 88 bytes per cache block on a 64 bit machine. SMQ uses 28bit indexes to implement it's data structures rather than pointers. It avoids storing an explicit hit count for each block. It has a 'hotspot' queue rather than a pre cache which uses a quarter of the entries (each hotspot block covers a larger area than a single cache block). All these mean smq uses ~25bytes per cache block. Still a lot of memory, but a substantial improvement nontheless. Level balancing --------------- MQ places entries in different levels of the multiqueue structures based on their hit count (~ln(hit count)). This means the bottom levels generally have the most entries, and the top ones have very few. Having unbalanced levels like this reduces the efficacy of the multiqueue. SMQ does not maintain a hit count, instead it swaps hit entries with the least recently used entry from the level above. The over all ordering being a side effect of this stochastic process. With this scheme we can decide how many entries occupy each multiqueue level, resulting in better promotion/demotion decisions. Adaptability ------------ The MQ policy maintains a hit count for each cache block. For a different block to get promoted to the cache it's hit count has to exceed the lowest currently in the cache. This means it can take a long time for the cache to adapt between varying IO patterns. Periodically degrading the hit counts could help with this, but I haven't found a nice general solution. SMQ doesn't maintain hit counts, so a lot of this problem just goes away. In addition it tracks performance of the hotspot queue, which is used to decide which blocks to promote. If the hotspot queue is performing badly then it starts moving entries more quickly between levels. This lets it adapt to new IO patterns very quickly. Performance ----------- In my tests SMQ shows substantially better performance than MQ. Once this matures a bit more I'm sure it'll become the default policy.

The 'timeout' value comes from userspace (CLOCK_MONOTONIC), but converting this directly to jiffies doesn't take into account the initial jiffies count at boot, which may differ from the base time of CLOCK_MONOTONIC. TODO: add ktime_delta_jiffies() when rebasing on 4.1 and use that instead of ktime_sub/ktime_to_timespec/timespec_to_jiffies combo (as suggested by Arnd) v2: switch over from 'struct timespec' to ktime_t throughout, since 'struct timespec' will be deprecated (as suggested by Arnd) v3: minor cosmetic tweaks Cc: Arnd Bergmann <arnd@arndb.de> Signed-off-by: Rob Clark <robdclark@gmail.com>
