Pull ARM devicetree updates from Arnd Bergmann: "There are six new SoCs added this time. Apple M1 and Nuvoton WPCM450 have separate branches because they are new SoC families that require changes outside of device tree files. The other four are variations of already supported chips and get merged through this branch: - STMicroelectronics STM32H750 is one of many variants of STM32 microcontrollers based on the Cortex-M7 core. This is particularly notable since we rarely add support for new MMU-less chips these days. In this case, the board that gets added along with the platform is not a SoC reference platform but the "Art Pi" (https://art-pi.gitee.io/website/) machine that was originally design for the RT-Thread RTOS. - NXP i.MX8QuadMax is a variant of the growing i.MX8 embedded/industrial SoC family, using two Cortex-A72 and four Cortex-A53 cores. It gets added along with its reference board, the "NXP i.MX8QuadMax Multisensory Enablement Kit". - Qualcomm SC7280 is a Laptop SoC following the SC7180 (Snapdragon 7c) that is used in some Chromebooks and Windows laptops. Only a reference board is added for the moment. - TI AM64x Sita4ra is a new version of the K3 SoC family for industrial control, motor control, remote IO, IoT gateway etc., similar to the older AM65x family. Two reference machines are added alongside. Among the newly added machines, there is a very clear skew towards 64-bit machines now, with 12 32-bit machines compared to 23 64-bit machines. The full list sorted by SoC is: - ASpeed AST2500 BMC: ASRock E3C246D4I Xeon server board - Allwinner A10: Topwise A721 Tablet - Amlogic GXL: MeCool KII TV box - Amlogic GXM: Mecool KIII, Minix Neo U9-H TV boxes - Broadcom BCM4908: TP-Link Archer C2300 V1 router - MStar SSD202D: M5Stack UnitV2 camera - Marvell Armada 38x: ATL-x530 ethernet switch - Mediatek MT8183 Chromebooks: Lenovo 10e, Acer Spin 311, Asus Flip CM3, Asus Detachable CM3 - Mediatek MT8516/MT8183: OLogic Pumpkin Board - NXP i.MX7: reMarkable Tablet - NXP i.MX8M: Kontron pitx-imx8m, Engicam i.Core MX8M Mini - Nuvoton NPCM730: Quanta GBS BMC - Qualcomm X55: Telit FN980 TLB SoM, Thundercomm TurboX T55 SoM - Qualcomm MSM8998: OnePlus 5/5T phones - Qualcomm SM8350: Snapdragon 888 Mobile Hardware Development Kit - Rockchip RK3399: NanoPi R4S board - STM32MP1: Engicam MicroGEA STM32MP1 MicroDev 2.0 and SOM, EDIMM2.2 Starter Kit, Carrier, SOM - TI AM65: Siemens SIMATIC IOT2050 gateway There is notable work going into extending already supported machines and SoCs: - ASpeed AST2500 - Allwinner A23, A83t, A31, A64, H6 - Amlogic G12B - Broadcom BCM4908 - Marvell Armada 7K/8K/CN91xx - Mediatek MT6589, MT7622, MT8173, MT8183, MT8195 - NXP i.MX8Q, i.MX8MM, i.MX8MP - Qualcomm MSM8916, SC7180, SDM845, SDX55, SM8350 - Renesas R-Car M3, V3U - Rockchip RK3328, RK3399 - STEricsson U8500 - STMicroelectronics STM32MP141 - Samsung Exynos 4412 - TI K3-AM65, K3-J7200 - TI OMAP3 Among the treewide cleanups and bug fixes, two parts stand out: - There are a number of cleanups for issues pointed out by 'make dtbs_check' this time, and I expect more to come in the future as we increasingly check for regressions. - After a change to the MMC subsystem that can lead to unpredictable device numbers, several platforms add 'aliases' properties for these to give each MMC controller a fixed number" * tag 'arm-dt-5.13' of git://git.kernel.org/pub/scm/linux/kernel/git/soc/soc: (516 commits) dt-bindings: mali-bifrost: add dma-coherent arm64: dts: amlogic: misc DT schema fixups arm64: dts: qcom: sc7180: Update iommu property for simultaneous playback arm64: dts: qcom: sc7180: pompom: Add "dmic_clk_en" + sound model arm64: dts: qcom: sc7180: coachz: Add "dmic_clk_en" ARM: dts: mstar: Add a dts for M5Stack UnitV2 dt-bindings: arm: mstar: Add compatible for M5Stack UnitV2 dt-bindings: vendor-prefixes: Add vendor prefix for M5Stack arm64: dts: mt8183: fix dtbs_check warning arm64: dts: mt8183-pumpkin: fix dtbs_check warning ARM: dts: aspeed: tiogapass: add hotplug controller ARM: dts: aspeed: amd-ethanolx: Enable all used I2C busses ARM: dts: aspeed: Rainier: Update to pass 2 hardware ARM: dts: aspeed: Rainier 1S4U: Fix fan nodes ARM: dts: aspeed: Rainier: Fix humidity sensor bus address ARM: dts: aspeed: Rainier: Fix PCA9552 on bus 8 ARM: dts: qcom: sdx55: add IPA information ARM: dts: qcom: sdx55: Add basic devicetree support for Thundercomm T55 dt-bindings: arm: qcom: Add binding for Thundercomm T55 kit ARM: dts: qcom: sdx55: Add basic devicetree support for Telit FN980 TLB ...

It triggers #DB and is restricted to operations in user space. Kernel side split lock access can only be detected by the #AC based variant. Contrary to the #AC based mechanism the #DB based variant triggers _after_ the instruction was executed.

git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip Pull entry code update from Thomas Gleixner: "Provide support for randomized stack offsets per syscall to make stack-based attacks harder which rely on the deterministic stack layout. The feature is based on the original idea of PaX's RANDSTACK feature, but uses a significantly different implementation. The offset does not affect the pt_regs location on the task stack as this was agreed on to be of dubious value. The offset is applied before the actual syscall is invoked. The offset is stored per cpu and the randomization happens at the end of the syscall which is less predictable than on syscall entry. The mechanism to apply the offset is via alloca(), i.e. abusing the dispised VLAs. This comes with the drawback that stack-clash-protection has to be disabled for the affected compilation units and there is also a negative interaction with stack-protector. Those downsides are traded with the advantage that this approach does not require any intrusive changes to the low level assembly entry code, does not affect the unwinder and the correct stack alignment is handled automatically by the compiler. The feature is guarded with a static branch which avoids the overhead when disabled. Currently this is supported for X86 and ARM64" * tag 'x86-entry-2021-04-26' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip: arm64: entry: Enable random_kstack_offset support lkdtm: Add REPORT_STACK for checking stack offsets x86/entry: Enable random_kstack_offset support stack: Optionally randomize kernel stack offset each syscall init_on_alloc: Optimize static branches jump_label: Provide CONFIG-driven build state defaults

git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip Pull irq updates from Thomas Gleixner: "The usual updates from the irq departement: Core changes: - Provide IRQF_NO_AUTOEN as a flag for request*_irq() so drivers can be cleaned up which either use a seperate mechanism to prevent auto-enable at request time or have a racy mechanism which disables the interrupt right after request. - Get rid of the last usage of irq_create_identity_mapping() and remove the interface. - An overhaul of tasklet_disable(). Most usage sites of tasklet_disable() are in task context and usually in cleanup, teardown code pathes. tasklet_disable() spinwaits for a tasklet which is currently executed. That's not only a problem for PREEMPT_RT where this can lead to a live lock when the disabling task preempts the softirq thread. It's also problematic in context of virtualization when the vCPU which runs the tasklet is scheduled out and the disabling code has to spin wait until it's scheduled back in. There are a few code pathes which invoke tasklet_disable() from non-sleepable context. For these a new disable variant which still spinwaits is provided which allows to switch tasklet_disable() to a sleep wait mechanism. For the atomic use cases this does not solve the live lock issue on PREEMPT_RT. That is mitigated by blocking on the RT specific softirq lock. - The PREEMPT_RT specific implementation of softirq processing and local_bh_disable/enable(). On RT enabled kernels soft interrupt processing happens always in task context and all interrupt handlers, which are not explicitly marked to be invoked in hard interrupt context are forced into task context as well. This allows to protect against softirq processing with a per CPU lock, which in turn allows to make BH disabled regions preemptible. Most of the softirq handling code is still shared. The RT/non-RT specific differences are addressed with a set of inline functions which provide the context specific functionality. The local_bh_disable() / local_bh_enable() mechanism are obviously seperate. - The usual set of small improvements and cleanups Driver changes: - New drivers for Nuvoton WPCM450 and DT 79rc3243x interrupt controllers - Extended functionality for MStar, STM32 and SC7280 irq chips - Enhanced robustness for ARM GICv3/4.1 drivers - The usual set of cleanups and improvements all over the place" * tag 'irq-core-2021-04-26' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip: (53 commits) irqchip/xilinx: Expose Kconfig option for Zynq/ZynqMP irqchip/gic-v3: Do not enable irqs when handling spurious interrups dt-bindings: interrupt-controller: Add IDT 79RC3243x Interrupt Controller irqchip: Add support for IDT 79rc3243x interrupt controller irqdomain: Drop references to recusive irqdomain setup irqdomain: Get rid of irq_create_strict_mappings() irqchip/jcore-aic: Kill use of irq_create_strict_mappings() ARM: PXA: Kill use of irq_create_strict_mappings() irqchip/gic-v4.1: Disable vSGI upon (GIC CPUIF < v4.1) detection irqchip/tb10x: Use 'fallthrough' to eliminate a warning genirq: Reduce irqdebug cacheline bouncing kernel: Initialize cpumask before parsing irqchip/wpcm450: Drop COMPILE_TEST irqchip/irq-mst: Support polarity configuration irqchip: Add driver for WPCM450 interrupt controller dt-bindings: interrupt-controller: Add nuvoton, wpcm450-aic dt-bindings: qcom,pdc: Add compatible for sc7280 irqchip/stm32: Add usart instances exti direct event support irqchip/gic-v3: Fix OF_BAD_ADDR error handling irqchip/sifive-plic: Mark two global variables __ro_after_init ...

2021-04-15Documentation: dev-tools: Add Testing OverviewDavid Gow2-0/+121
The kernel now has a number of testing and debugging tools, and we've seen a bit of confusion about what the differences between them are. Add a basic documentation outlining the testing tools, when to use each, and how they interact. This is a pretty quick overview rather than the idealised "kernel testing guide" that'd probably be optimal, but given the number of times questions like "When do you use KUnit and when do you use Kselftest?" are being asked, it seemed worth at least having something. Hopefully this can form the basis for more detailed documentation later.
