I'll have a "late" 6.1-rc1 pull for you that removes the now unused prandom_u32_max() function, just in case any other trees add a new use case of it that needs to converted. According to linux-next, there may be two trivial cases of prandom_u32_max() reintroductions that are fixable with a 's/.../.../'. So I'll have for you a final conversion patch doing that alongside the removal patch during the second week. This is a treewide change that touches many files throughout. - More consistent use of get_random_canary(). - Updates to comments, documentation, tests, headers, and simplification in configuration. - The arch_get_random*_early() abstraction was only used by arm64 and wasn't entirely useful, so this has been replaced by code that works in all relevant contexts. - The kernel will use and manage random seeds in non-volatile EFI variables, refreshing a variable with a fresh seed when the RNG is initialized. The RNG GUID namespace is then hidden from efivarfs to prevent accidental leakage. These changes are split into random.c infrastructure code used in the EFI subsystem, in this pull request, and related support inside of EFISTUB, in Ard's EFI tree. These are co-dependent for full functionality, but the order of merging doesn't matter. - Part of the infrastructure added for the EFI support is also used for an improvement to the way vsprintf initializes its siphash key, replacing an sleep loop wart. - The hardware RNG framework now always calls its correct random.c input function, add_hwgenerator_randomness(), rather than sometimes going through helpers better suited for other cases. - The add_latent_entropy() function has long been called from the fork handler, but is a no-op when the latent entropy gcc plugin isn't used, which is fine for the purposes of latent entropy. But it was missing out on the cycle counter that was also being mixed in beside the latent entropy variable. So now, if the latent entropy gcc plugin isn't enabled, add_latent_entropy() will expand to a call to add_device_randomness(NULL, 0), which adds a cycle counter, without the absent latent entropy variable. - The RNG is now reseeded from a delayed worker, rather than on demand when used. Always running from a worker allows it to make use of the CPU RNG on platforms like S390x, whose instructions are too slow to do so from interrupts. It also has the effect of adding in new inputs more frequently with more regularity, amounting to a long term transcript of random values. Plus, it helps a bit with the upcoming vDSO implementation (which isn't yet ready for 6.2). - The jitter entropy algorithm now tries to execute on many different CPUs, round-robining, in hopes of hitting even more memory latencies and other unpredictable effects. It also will mix in a cycle counter when the entropy timer fires, in addition to being mixed in from the main loop, to account more explicitly for fluctuations in that timer firing. And the state it touches is now kept within the same cache line, so that it's assured that the different execution contexts will cause latencies. * tag 'random-6.2-rc1-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/crng/random: (23 commits) random: include <linux/once.h> in the right header random: align entropy_timer_state to cache line random: mix in cycle counter when jitter timer fires random: spread out jitter callback to different CPUs random: remove extraneous period and add a missing one in comments efi: random: refresh non-volatile random seed when RNG is initialized vsprintf: initialize siphash key using notifier random: add back async readiness notifier random: reseed in delayed work rather than on-demand random: always mix cycle counter in add_latent_entropy() hw_random: use add_hwgenerator_randomness() for early entropy random: modernize documentation comment on get_random_bytes() random: adjust comment to account for removed function random: remove early archrandom abstraction random: use random.trust_{bootloader,cpu} command line option only stackprotector: actually use get_random_canary() stackprotector: move get_random_canary() into stackprotector.h treewide: use get_random_u32_inclusive() when possible treewide: use get_random_u32_{above,below}() instead of manual loop treewide: use get_random_u32_below() instead of deprecated function ...

This solves conceptual problems of the current PCI/MSI design which are in the way of providing support for PCI/MSI[-X] and the upcoming PCI/IMS mechanism on the same device. IMS (Interrupt Message Store] is a new specification which allows device manufactures to provide implementation defined storage for MSI messages (as opposed to PCI/MSI and PCI/MSI-X that has a specified message store which is uniform accross all devices). The PCI/MSI[-X] uniformity allowed us to get away with "global" PCI/MSI domains. IMS not only allows to overcome the size limitations of the MSI-X table, but also gives the device manufacturer the freedom to store the message in arbitrary places, even in host memory which is shared with the device. There have been several attempts to glue this into the current MSI code, but after lengthy discussions it turned out that there is a fundamental design problem in the current PCI/MSI-X implementation. This needs some historical background. When PCI/MSI[-X] support was added around 2003, interrupt management was completely different from what we have today in the actively developed architectures. Interrupt management was completely architecture specific and while there were attempts to create common infrastructure the commonalities were rudimentary and just providing shared data structures and interfaces so that drivers could be written in an architecture agnostic way. The initial PCI/MSI[-X] support obviously plugged into this model which resulted in some basic shared infrastructure in the PCI core code for setting up MSI descriptors, which are a pure software construct for holding data relevant for a particular MSI interrupt, but the actual association to Linux interrupts was completely architecture specific. This model is still supported today to keep museum architectures and notorious stragglers alive. In 2013 Intel tried to add support for hot-pluggable IO/APICs to the kernel, which was creating yet another architecture specific mechanism and resulted in an unholy mess on top of the existing horrors of x86 interrupt handling. The x86 interrupt management code was already an incomprehensible maze of indirections between the CPU vector management, interrupt remapping and the actual IO/APIC and PCI/MSI[-X] implementation. At roughly the same time ARM struggled with the ever growing SoC specific extensions which were glued on top of the architected GIC interrupt controller. This resulted in a fundamental redesign of interrupt management and provided the today prevailing concept of hierarchical interrupt domains. This allowed to disentangle the interactions between x86 vector domain and interrupt remapping and also allowed ARM to handle the zoo of SoC specific interrupt components in a sane way. The concept of hierarchical interrupt domains aims to encapsulate the functionality of particular IP blocks which are involved in interrupt delivery so that they become extensible and pluggable. The X86 encapsulation looks like this: |--- device 1 [Vector]---[Remapping]---[PCI/MSI]--|... |--- device N where the remapping domain is an optional component and in case that it is not available the PCI/MSI[-X] domains have the vector domain as their parent. This reduced the required interaction between the domains pretty much to the initialization phase where it is obviously required to establish the proper parent relation ship in the components of the hierarchy. While in most cases the model is strictly representing the chain of IP blocks and abstracting them so they can be plugged together to form a hierarchy, the design stopped short on PCI/MSI[-X]. Looking at the hardware it's clear that the actual PCI/MSI[-X] interrupt controller is not a global entity, but strict a per PCI device entity. Here we took a short cut on the hierarchical model and went for the easy solution of providing "global" PCI/MSI domains which was possible because the PCI/MSI[-X] handling is uniform across the devices. This also allowed to keep the existing PCI/MSI[-X] infrastructure mostly unchanged which in turn made it simple to keep the existing architecture specific management alive. A similar problem was created in the ARM world with support for IP block specific message storage. Instead of going all the way to stack a IP block specific domain on top of the generic MSI domain this ended in a construct which provides a "global" platform MSI domain which allows overriding the irq_write_msi_msg() callback per allocation. In course of the lengthy discussions we identified other abuse of the MSI infrastructure in wireless drivers, NTB etc. where support for implementation specific message storage was just mindlessly glued into the existing infrastructure. Some of this just works by chance on particular platforms but will fail in hard to diagnose ways when the driver is used on platforms where the underlying MSI interrupt management code does not expect the creative abuse. Another shortcoming of today's PCI/MSI-X support is the inability to allocate or free individual vectors after the initial enablement of MSI-X. This results in an works by chance implementation of VFIO (PCI pass-through) where interrupts on the host side are not set up upfront to avoid resource exhaustion. They are expanded at run-time when the guest actually tries to use them. The way how this is implemented is that the host disables MSI-X and then re-enables it with a larger number of vectors again. That works by chance because most device drivers set up all interrupts before the device actually will utilize them. But that's not universally true because some drivers allocate a large enough number of vectors but do not utilize them until it's actually required, e.g. for acceleration support. But at that point other interrupts of the device might be in active use and the MSI-X disable/enable dance can just result in losing interrupts and therefore hard to diagnose subtle problems. Last but not least the "global" PCI/MSI-X domain approach prevents to utilize PCI/MSI[-X] and PCI/IMS on the same device due to the fact that IMS is not longer providing a uniform storage and configuration model. The solution to this is to implement the missing step and switch from global PCI/MSI domains to per device PCI/MSI domains. The resulting hierarchy then looks like this: |--- [PCI/MSI] device 1 [Vector]---[Remapping]---|... |--- [PCI/MSI] device N which in turn allows to provide support for multiple domains per device: |--- [PCI/MSI] device 1 |--- [PCI/IMS] device 1 [Vector]---[Remapping]---|... |--- [PCI/MSI] device N |--- [PCI/IMS] device N This work converts the MSI and PCI/MSI core and the x86 interrupt domains to the new model, provides new interfaces for post-enable allocation/free of MSI-X interrupts and the base framework for PCI/IMS. PCI/IMS has been verified with the work in progress IDXD driver. There is work in progress to convert ARM over which will replace the platform MSI train-wreck. The cleanup of VFIO, NTB and other creative "solutions" are in the works as well.

The most notable changes, by SoC platform, are: - The Apple T6000 (M1 Pro), T6001 (M1 Max) and T6002 (M1 Ultra) chips now have initial support. This is particularly nice as I am typing this on a T6002 Mac Studio with only a small number of driver patches. - Qualcomm MSM8996 Pro (Snapdragon 821), SM6115 (Snapdragon 662), SM4250 (Snapdragon 460), SM6375 (Snapdragon 695), SDM670 (Snapdragon 670), MSM8976 (Snapdragon 652) and MSM8956 (Snapdragon 650) are all mobile phone chips that are closely related to others we already support. Adding those helps support more phones and we add several models from Sony (Xperia 10 IV, 5 IV, X, and X compact), OnePlus (One, 3, 3T, and Nord N100), Xiaomi (Poco F1, Mi6), Huawei (Watch) and Google (Pixel 3a). There are also new variants of the Herobrine and Trogdor chromebook motherboards. SA8540P is an automotive SoC used in the Qdrive-3 development platform - Rockchips gains no new SoC variants, but a lot of new boards: three mobile gaming systems based on RK3326 Odroid-Go/rg351 family, two more Anbernic gaming systems based on RK3566 and a number of other RK356x based single-board computers. - Renesas RZ/G2UL (r9a07g043) was already supported for arm64, but as the newly added RZ/Five is based on the same design, this now gets reorganized in order to share most of the dts description between the two and add the RZ/Five SMARC EVK board support. Aside from that, there are the usual changes all over the tree: - New boards on other platforms contain two ASpeed BMC users, two Broadcom based Wifi routers, Zyxel NSA310S NAS, the i.MX6 based Kobo Aura2 ebook reader, two i.MX8 based development boards, two Uniphier Pro5 development boards, the STM32MP1 testbench board from DHCOR, the TI K3 based BeagleBone AI-64 board, and the Mediatek Helio X10 based Sony Xperia M5 phone. - The Starfive JH7100 source gets reorganized in order to support the VisionFive V1 board. - Minor updates and cleanups for Intel SoCFPGA, Marvell PXA168, TI, ST, NXP, Apple, Broadcom, Juno, Marvell MVEBU, at91, nuvoton, Tegra, Mediatek, Renesas, Hisilicon, Allwinner, Samsung, ux500, spear, ... The treewide cleanups now have a lot of fixes for cache nodes and other binding violoations. - Somewhat larger sets of reworks for NVIDIA Tegra, Qualcomm and Renesas platforms, adding a lot more on-chip device support - A rework of the way that DTB overlays are built" * tag 'soc-dt-6.2' of git://git.kernel.org/pub/scm/linux/kernel/git/soc/soc: (979 commits) arm64: dts: apple: t6002: Fix GPU power domains arm64: dts: apple: t600x-pmgr: Fix search & replace typo arm64: dts: apple: Add t8103 L1/L2 cache properties and nodes arm64: dts: apple: Rename dart-sio* to sio-dart* arch: arm64: apple: t600x: Use standard "iommu" node name arch: arm64: apple: t8103: Use standard "iommu" node name ARM: dts: socfpga: Fix pca9548 i2c-mux node name dt-bindings: iio: adc: qcom,spmi-vadc: fix PM8350 define dt-bindings: iio: adc: qcom,spmi-vadc: extend example arm64: dts: qcom: sc8280xp: fix UFS DMA coherency arm64: dts: qcom: sc7280: Add DT for sc7280-herobrine-zombie arm64: dts: qcom: sm8250-sony-xperia-edo: fix no-mmc property for SDHCI arm64: dts: qcom: sdm845-sony-xperia-tama: fix no-mmc property for SDHCI arm64: dts: qcom: sda660-inforce-ifc6560: fix no-mmc property for SDHCI arm64: dts: qcom: sa8155p-adp: fix no-mmc property for SDHCI arm64: dts: qcom: qrb5165-rb: fix no-mmc property for SDHCI arm64: dts: qcom: sm8450: align MMC node names with dtschema arm64: dts: qcom: sc7180-trogdor: use generic node names arm64: dts: qcom: sm8450-hdk: add sound support arm64: dts: qcom: sm8450: add Soundwire and LPASS ...

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | We face some regressions on a few IXP42x systems when accessing flash, the following unrelated error prints appear from the PCI driver: ixp4xx-pci c0000000.pci: PCI: abort_handler addr = 0xff9ffb5f, isr = 0x0, status = 0x22a0 ixp4xx-pci c0000000.pci: imprecise abort (...) It turns out that while bit 7 is masked "reserved" it is not unused, so masking it off as zero is dangerous, and breaks flash access on some systems such as the NSLU2. Be more careful and avoid masking off any of the reserved bits 7, 8, 9 or 30. Only keep masking EXP_WORD (bit 2) on IXP43x which is necessary in some setups.

So instead of allocating and destroying the IRQs all the time, let's just enable/disable IRQs during power up/down. The IRQs will be allocated during mhi_register_controller() and freed during mhi_unregister_controller(). This works well for things like PCI hotplug also as once the PCI device gets removed, the controller will get unregistered. And once it comes back, it will get registered back and even if the IRQ configuration changes (MSI), that will get accounted.

This will help to eliminate the children list head from struct acpi_device as it is redundant and it is used in questionable ways in some places (in particular, locking is needed for walking the list pointed to it safely, but it is often missing). While at it, simplify hisi_lpc_acpi_set_io_res() by making it accept a struct acpi_device pointer from the caller, instead of going to struct device and back to get the same result, and clean up confusion regarding hostdev and its ACPI companion in that function. Also remove a redundant check from it. Signed-off-by: Rafael J.

Lots of tiny driver core changes and cleanups happened this cycle, but the two major things are: - firmware_loader reorganization and additions including the ability to have XZ compressed firmware images and the ability for userspace to initiate the firmware load when it needs to, instead of being always initiated by the kernel. FPGA devices specifically want this ability to have their firmware changed over the lifetime of the system boot, and this allows them to work without having to come up with yet-another-custom-uapi interface for loading firmware for them. - physical location support added to sysfs so that devices that know this information, can tell userspace where they are located in a common way. Some ACPI devices already support this today, and more bus types should support this in the future. Smaller changes include: - driver_override api cleanups and fixes - error path cleanups and fixes - get_abi script fixes - deferred probe timeout changes. It's that last change that I'm the most worried about. It has been reported to cause boot problems for a number of systems, and I have a tested patch series that resolves this issue. But I didn't get it merged into my tree before 5.18-final came out, so it has not gotten any linux-next testing. I'll send the fixup patches (there are 2) as a follow-on series to this pull request.
