Commit 0b0393d59eb4a ("media: uapi: h264: clarify expected scaling_list_4x4/8x8 order") improved the documentation on H264 scaling lists order. This commit improves the documentation by clarifying that the lists themselves are expected in raster scan order.

2020-09-01media: uapi: h264: Update reference listsJernej Skrabec1-2/+42
When dealing with interlaced frames, reference lists must tell if each particular reference is meant for top or bottom field. This info is currently not provided at all in the H264 related controls. Change reference lists to hold a structure, which specifies an index into the DPB array and the field/frame specification for the picture. Currently the only user of these lists is Cedrus which is just compile fixed here. Actual usage of will come in a following commit.

2020-09-01Documentation/x86: Add documentation for /proc/cpuinfo feature flagsKyung Min Park2-0/+156
/proc/cpuinfo shows features which the kernel supports. Some of these flags are derived from CPUID, and others are derived from other sources, including some that are entirely software-based. Currently, there is not any documentation in the kernel about how /proc/cpuinfo flags are generated and what it means when they are missing. Add documentation for /proc/cpuinfo feature flags enumeration. Document how and when x86 feature flags are used. Also discuss what their presence or absence mean for the kernel and users.

2020-09-01dma-contiguous: provide the ability to reserve per-numa CMABarry Song1-0/+11
Right now, drivers like ARM SMMU are using dma_alloc_coherent() to get coherent DMA buffers to save their command queues and page tables. As there is only one default CMA in the whole system, SMMUs on nodes other than node0 will get remote memory. This leads to significant latency. This patch provides per-numa CMA so that drivers like SMMU can get local memory. Tests show localizing CMA can decrease dma_unmap latency much. For instance, before this patch, SMMU on node2 has to wait for more than 560ns for the completion of CMD_SYNC in an empty command queue; with this patch, it needs 240ns only. A positive side effect of this patch would be improving performance even further for those users who are worried about performance more than DMA security and use iommu.passthrough=1 to skip IOMMU. With local CMA, all drivers can get local coherent DMA buffers. Also, this patch changes the default CONFIG_CMA_AREAS to 19 in NUMA. As 1+CONFIG_CMA_AREAS should be quite enough for most servers on the market even they enable both hugetlb_cma and pernuma_cma. 2 numa nodes: 2(hugetlb) + 2(pernuma) + 1(default global cma) = 5 4 numa nodes: 4(hugetlb) + 4(pernuma) + 1(default global cma) = 9 8 numa nodes: 8(hugetlb) + 8(pernuma) + 1(default global cma) = 17 Signed-off-by: Barry Song <song.bao.hua@hisilicon.com> Signed-off-by: Christoph Hellwig <hch@lst.de>
2020-08-31Documentation: clarify driver licensing rulesDave Hansen1-4/+5
Greg has challenged some recent driver submitters on their license choices. He was correct to do so, as the choices in these instances did not always advance the aims of the submitters. But, this left submitters (and the folks who help them pick licenses) a bit confused. They have read things like Documentation/process/license-rules.rst which says: individual source files can have a different license which is required to be compatible with the GPL-2.0 and Documentation/process/submitting-drivers.rst: We don't insist on any kind of exclusive GPL licensing, and if you wish ... you may well wish to release under multiple licenses. As written, these appear a _bit_ more laissez faire than we've been in practice lately. It sounds like we at least expect submitters to make a well-reasoned license choice and to explain their rationale. It does not appear that we blindly accept anything that is simply GPLv2-compatible. Drivers appear to be the most acute source of misunderstanding, so fix the driver documentation first. Update it to clarify expectations.

Based on a vote at the LLVM BoF at Plumbers 2020, we decided to start small, supporting just one formal upstream release of LLVM for now. We can probably widen the support window of supported versions over time. Also, note that LLVM's release process is different than GCC's. GCC tends to have 1 major release per year while releasing minor updates to the past 3 major versions. LLVM tends to support one major release and one minor release every six months.

2020-08-31Documentation/llvm: Improve formatting of commands, variables, and argumentsNathan Chancellor1-13/+13
While reviewing a separate patch, I noticed that the formatting of the commands, variables, and arguments was not in a monospaced font like the rest of the Kbuild documentation (see kbuild/kconfig.rst for an example). This is due to a lack of "::" before indented command blocks and single backticks instead of double backticks for inline formatting. Add those so that the document looks nicer in an HTML format, while not ruining the look in plain text. As a result of this, we can remove the escaped backslashes in the last code block and move them to single backslashes.

Pull irq fixes from Thomas Gleixner: "A set of fixes for interrupt chip drivers: - Revert the platform driver conversion of interrupt chip drivers as it turned out to create more problems than it solves. - Fix a trivial typo in the new module helpers which made probing reliably fail. - Small fixes in the STM32 and MIPS Ingenic drivers - The TI firmware rework which had badly managed dependencies and had to wait post rc1" * tag 'irq-urgent-2020-08-30' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip: irqchip/ingenic: Leave parent IRQ unmasked on suspend irqchip/stm32-exti: Avoid losing interrupts due to clearing pending bits by mistake irqchip: Revert modular support for drivers using IRQCHIP_PLATFORM_DRIVER helperse irqchip: Fix probing deferal when using IRQCHIP_PLATFORM_DRIVER helpers arm64: dts: k3-am65: Update the RM resource types arm64: dts: k3-am65: ti-sci-inta/intr: Update to latest bindings arm64: dts: k3-j721e: ti-sci-inta/intr: Update to latest bindings irqchip/ti-sci-inta: Add support for INTA directly connecting to GIC irqchip/ti-sci-inta: Do not store TISCI device id in platform device id field dt-bindings: irqchip: Convert ti, sci-inta bindings to yaml dt-bindings: irqchip: ti, sci-inta: Update docs to support different parent. irqchip/ti-sci-intr: Add support for INTR being a parent to INTR dt-bindings: irqchip: Convert ti, sci-intr bindings to yaml dt-bindings: irqchip: ti, sci-intr: Update bindings to drop the usage of gic as parent firmware: ti_sci: Add support for getting resource with subtype firmware: ti_sci: Drop unused structure ti_sci_rm_type_map firmware: ti_sci: Drop the device id to resource type translation

Pull powerpc fixes from Michael Ellerman: - Revert our removal of PROT_SAO, at least one user expressed an interest in using it on Power9. Instead don't allow it to be used in guests unless enabled explicitly at compile time. - A fix for a crash introduced by a recent change to FP handling. - Revert a change to our idle code that left Power10 with no idle support. - One minor fix for the new scv system call path to set PPR. - Fix a crash in our "generic" PMU if branch stack events were enabled. - A fix for the IMC PMU, to correctly identify host kernel samples. - The ADB_PMU powermac code was found to be incompatible with VMAP_STACK, so make them incompatible in Kconfig until the code can be fixed. - A build fix in drivers/video/fbdev/controlfb.c, and a documentation fix.
