2019-08-21media: dt-bindings: media: Convert Allwinner A10 IR to a schemaMaxime Ripard
The older Allwinner SoCs have a IR receiver supported in Linux, with a matching Device Tree binding. Now that we have the DT validation in place, let's convert the device tree bindings for that controller over to a YAML schemas.

2019-08-19media: docs-rst: Document memory-to-memory video decoder interfaceTomasz Figa
Due to complexity of the video decoding process, the V4L2 drivers of stateful decoder hardware require specific sequences of V4L2 API calls to be followed. These include capability enumeration, initialization, decoding, seek, pause, dynamic resolution change, drain and end of stream. Specifics of the above have been discussed during Media Workshops at LinuxCon Europe 2012 in Barcelona and then later Embedded Linux Conference Europe 2014 in Düsseldorf. The de facto Codec API that originated at those events was later implemented by the drivers we already have merged in mainline, such as s5p-mfc or coda. The only thing missing was the real specification included as a part of Linux Media documentation. Fix it now and document the decoder part of the Codec API.

2019-08-19media: videodev2.h: add V4L2_FMT_FLAG_DYN_RESOLUTIONMaxime Jourdan
Add an enum_fmt format flag to specifically tag coded formats where dynamic resolution switching is supported by the device. This is useful for some codec drivers that can support dynamic resolution switching for one or more of their listed coded formats. It allows userspace to know whether it should extract the video parameters itself, or if it can rely on the device to send V4L2_EVENT_SOURCE_CHANGE when such changes are detected.

Add an enum_fmt format flag to specifically tag coded formats where full bytestream parsing is supported by the device. Some stateful decoders are capable of fully parsing a bytestream, but others require that userspace pre-parses the bytestream into frames or fields (see the corresponding pixelformat descriptions for details). If this flag is set, then this pre-parsing step is not required (but still possible, of course).

2019-08-19media: uapi: h264: Add the concept of start codeEzequiel Garcia
Stateless decoders have different expectations about the start code that is prepended on H264 slices. Add a menu control to express the supported start code types (including no start code). Drivers are allowed to support only one start code type, but they can support both too. Note that this is independent of the H264 decoding mode, which specifies the granularity of the decoding operations. Either in frame-based or slice-based mode, this new control will allow to define the start code expected on H264 slices.

When the support for serial busses was introduced in V4L2, it was decided to use the existing parallel bus media bus pixel codes to describe them. While this was a practical choice at the time, it necessitates choosing which one of the many parallel mbus pixel codes to use, for on the serial busses these formats are effectively all equivalent. The practice has always been to use the pixel code that describes a bus that transfers a single sample per clock. Document this.

git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip Pull pti updates from Thomas Gleixner: "The performance deterioration departement is not proud at all to present yet another set of speculation fences to mitigate the next chapter in the 'what could possibly go wrong' story. The new vulnerability belongs to the Spectre class and affects GS based data accesses and has therefore been dubbed 'Grand Schemozzle' for secret communication purposes. It's officially listed as CVE-2019-1125. Conditional branches in the entry paths which contain a SWAPGS instruction (interrupts and exceptions) can be mis-speculated which results in speculative accesses with a wrong GS base. This can happen on entry from user mode through a mis-speculated branch which takes the entry from kernel mode path and therefore does not execute the SWAPGS instruction. The following speculative accesses are done with user GS base. On entry from kernel mode the mis-speculated branch executes the SWAPGS instruction in the entry from user mode path which has the same effect that the following GS based accesses are done with user GS base. If there is a disclosure gadget available in these code paths the mis-speculated data access can be leaked through the usual side channels. The entry from user mode issue affects all CPUs which have speculative execution. The entry from kernel mode issue affects only Intel CPUs which can speculate through SWAPGS. On CPUs from other vendors SWAPGS has semantics which prevent that. SMAP migitates both problems but only when the CPU is not affected by the Meltdown vulnerability. The mitigation is to issue LFENCE instructions in the entry from kernel mode path for all affected CPUs and on the affected Intel CPUs also in the entry from user mode path unless PTI is enabled because the CR3 write is serializing. The fences are as usual enabled conditionally and can be completely disabled on the kernel command line. The Spectre V1 documentation is updated accordingly. A big "Thank You!" goes to Josh for doing the heavy lifting for this round of hardware misfeature 'repair'. Of course also "Thank You!" to everybody else who contributed in one way or the other" * 'x86/grand-schemozzle' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip: Documentation: Add swapgs description to the Spectre v1 documentation x86/speculation/swapgs: Exclude ATOMs from speculation through SWAPGS x86/entry/64: Use JMP instead of JMPQ x86/speculation: Enable Spectre v1 swapgs mitigations x86/speculation: Prepare entry code for Spectre v1 swapgs mitigations
