2014-03-11[media] media DocBook: fix NV16M descriptionHans Verkuil1-5/+4
The NV16M description contained some copy-and-paste text from NV12M, suggesting that this format is a 4:2:0 format when it really is a 4:2:2 format. Fixed the text.

2014-03-05[media] v4l: Document timestamp buffer flag behaviourSakari Ailus1-0/+14
Timestamp buffer flags are constant at the moment. Document them so that 1) they're always valid and 2) not changed by the drivers. This leaves room to extend the functionality later on if needed.

2014-03-05[media] v4l: Add timestamp source flags, mask and document themSakari Ailus1-6/+30
Some devices do not produce timestamps that correspond to the end of the frame. The user space should be informed on the matter. This patch achieves that by adding buffer flags (and a mask) for timestamp sources since more possible timestamping points are expected than just two. A three-bit mask is defined (V4L2_BUF_FLAG_TSTAMP_SRC_MASK) and two of the eight possible values is are defined V4L2_BUF_FLAG_TSTAMP_SRC_EOF for end of frame (value zero) V4L2_BUF_FLAG_TSTAMP_SRC_SOE for start of exposure (next value).

2014-03-05[media] v4l: Use full 32 bits for buffer flagsSakari Ailus1-15/+15
The buffer flags field is 32 bits but the defined only used 16. This is fine, but as more than 16 bits will be used in the very near future, define them as 32-bit numbers for consistency.

2014-03-05[media] v4l: Document timestamp behaviour to correspond to realitySakari Ailus1-44/+12
Document that monotonic timestamps are taken after the corresponding frame has been received, not when the reception has begun. This corresponds to the reality of current drivers: the timestamp is naturally taken when the hardware triggers an interrupt to tell the driver to handle the received frame. Remove the note on timestamp accuracy as it is fairly subjective what is actually an unstable timestamp. Also remove explanation that output buffer timestamps can be used to delay outputting a frame. Remove the footnote saying we always use realtime clock.

2014-02-12ALSA: Mandate to pass a device pointer at card creation timeTakashi Iwai1-45/+27
This is a part of preliminary works for modernizing the ALSA device structure. So far, we set card->dev at later point after the object creation. Because of this, the core layer doesn't always know which device is being handled before it's actually registered, and it makes impossible to show the device in error messages, for example. The first goal is to achieve a proper struct device initialization at the very beginning of probing. As a first step, this patch introduces snd_card_new() function (yes there was the same named function in the very past), in order to receive the parent device pointer from the very beginning. snd_card_create() is marked as deprecated. At this point, there is no functional change other than that. The actual change of the device creation scheme will follow later. Signed-off-by: Takashi Iwai <tiwai@suse.de>

2014-02-06[media] DocBook: Add a description for the Remote Controller interfaceMauro Carvalho Chehab1-1/+97
Adds a missing section to describe the remote controller interface. The DocBook is just addin the same documentation as written at Documentation/ABI/testing/sysfs-class-rc, using the DocBook's way, and dropping timestamps/contact info. While that means that we'll have the same info on two parts, there are parts of the remote controller interface that doesn't belong at Documentation/ABI/, and it makes sense to have everything on the same place. This also means that we'll need to manually track to be sure that both places will be synchronized, but, as it is not expected much changes on it, this sync can be done manually. It also adds an introduction that states that the IR is a normal evdev/input interface, plus the sysfs class nodes. Signed-off-by: Mauro Carvalho Chehab <m.chehab@samsung.com>

Updates for the "Tuners and Modulators", "Video Standards" and "Digital Video (DV) Timings" sections. Besides lots of trivial little fixes the main changes are: - Remove two footnotes from "Video Standards": the first is a discussion of alternative methods of setting standards, which is pretty pointless since the standards API is effectively frozen anyway, and the second points to 'rationale' that makes little or no sense to me. - Clarify a few things in the "Digital Video (DV) Timings" section. It was awkwardly formatted as well: there used to be a list with multiple bullets that has been reduced to a single item, so drop the list and rewrite that text.

So saying "The ioctl will succeed only when at least one output buffer is in the incoming queue." isn't true. Just drop the word 'only'.

Pull MTD changes from Brian Norris: - Unify some compile-time differences so that we have fewer uses of #ifdef CONFIG_OF in atmel_nand - Other general cleanups (removing unused functions, options, variables, fields; use correct interfaces) - Fix BUG() for new odd-sized NAND, which report non-power-of-2 dimensions via ONFI - Miscellaneous driver fixes (SPI NOR flash; BCM47xx NAND flash; etc.) - Improve differentiation between SLC and MLC NAND -- this clarifies an ABI issue regarding the MTD "type" (in sysfs and in the MEMGETINFO ioctl), where the MTD_MLCNANDFLASH type was present but inconsistently used - Extend GPMI NAND to support multi-chip-select NAND for some platforms - Many improvements to the OMAP2/3 NAND driver, including an expanded DT binding to bring us closer to mainline support for some OMAP systems - Fix a deadlock in the error path of the Atmel NAND driver probe - Correct the error codes from MTD mmap() to conform to POSIX and the Linux Programmer's Manual. This is an acknowledged change in the MTD ABI, but I can't imagine somebody relying on the non-standard -ENOSYS error code specifically. Am I just being unimaginative? :) - Fix a few important GPMI NAND bugs (one regression from 3.12 and one long-standing race condition) - More?

Pull networking updates from David Miller: 1) The addition of nftables. No longer will we need protocol aware firewall filtering modules, it can all live in userspace. At the core of nftables is a, for lack of a better term, virtual machine that executes byte codes to inspect packet or metadata (arriving interface index, etc.) and make verdict decisions. Besides support for loading packet contents and comparing them, the interpreter supports lookups in various datastructures as fundamental operations. For example sets are supports, and therefore one could create a set of whitelist IP address entries which have ACCEPT verdicts attached to them, and use the appropriate byte codes to do such lookups. Since the interpreted code is composed in userspace, userspace can do things like optimize things before giving it to the kernel. Another major improvement is the capability of atomically updating portions of the ruleset. In the existing netfilter implementation, one has to update the entire rule set in order to make a change and this is very expensive. Userspace tools exist to create nftables rules using existing netfilter rule sets, but both kernel implementations will need to co-exist for quite some time as we transition from the old to the new stuff. Kudos to Patrick McHardy, Pablo Neira Ayuso, and others who have worked so hard on this. 2) Daniel Borkmann and Hannes Frederic Sowa made several improvements to our pseudo-random number generator, mostly used for things like UDP port randomization and netfitler, amongst other things. In particular the taus88 generater is updated to taus113, and test cases are added. 3) Support 64-bit rates in HTB and TBF schedulers, from Eric Dumazet and Yang Yingliang. 4) Add support for new 577xx tigon3 chips to tg3 driver, from Nithin Sujir. 5) Fix two fatal flaws in TCP dynamic right sizing, from Eric Dumazet, Neal Cardwell, and Yuchung Cheng. 6) Allow IP_TOS and IP_TTL to be specified in sendmsg() ancillary control message data, much like other socket option attributes. From Francesco Fusco. 7) Allow applications to specify a cap on the rate computed automatically by the kernel for pacing flows, via a new SO_MAX_PACING_RATE socket option. From Eric Dumazet. 8) Make the initial autotuned send buffer sizing in TCP more closely reflect actual needs, from Eric Dumazet. 9) Currently early socket demux only happens for TCP sockets, but we can do it for connected UDP sockets too. Implementation from Shawn Bohrer. 10) Refactor inet socket demux with the goal of improving hash demux performance for listening sockets. With the main goals being able to use RCU lookups on even request sockets, and eliminating the listening lock contention. From Eric Dumazet. 11) The bonding layer has many demuxes in it's fast path, and an RCU conversion was started back in 3.11, several changes here extend the RCU usage to even more locations. From Ding Tianhong and Wang Yufen, based upon suggestions by Nikolay Aleksandrov and Veaceslav Falico. 12) Allow stackability of segmentation offloads to, in particular, allow segmentation offloading over tunnels. From Eric Dumazet. 13) Significantly improve the handling of secret keys we input into the various hash functions in the inet hashtables, TCP fast open, as well as syncookies. From Hannes Frederic Sowa. The key fundamental operation is "net_get_random_once()" which uses static keys. Hannes even extended this to ipv4/ipv6 fragmentation handling and our generic flow dissector. 14) The generic driver layer takes care now to set the driver data to NULL on device removal, so it's no longer necessary for drivers to explicitly set it to NULL any more. Many drivers have been cleaned up in this way, from Jingoo Han. 15) Add a BPF based packet scheduler classifier, from Daniel Borkmann. 16) Improve CRC32 interfaces and generic SKB checksum iterators so that SCTP's checksumming can more cleanly be handled. Also from Daniel Borkmann. 17) Add a new PMTU discovery mode, IP_PMTUDISC_INTERFACE, which forces using the interface MTU value. This helps avoid PMTU attacks, particularly on DNS servers. From Hannes Frederic Sowa. 18) Use generic XPS for transmit queue steering rather than internal (re-)implementation in virtio-net.
