Linus Torvalds b1f8ccdaae - Significant refactoring and fixing of how DM core does bio-based IO
accounting with focus on fixing wildly inaccurate IO stats for
   dm-crypt (and other DM targets that defer bio submission in their
   own workqueues). End result is proper IO accounting, made possible
   by targets being updated to use the new dm_submit_bio_remap()
   interface.
 
 - Add hipri bio polling support (REQ_POLLED) to bio-based DM.
 
 - Reduce dm_io and dm_target_io structs so that a single dm_io (which
   contains dm_target_io and first clone bio) weighs in at 256 bytes.
   For reference the bio struct is 128 bytes.
 
 - Various other small cleanups, fixes or improvements in DM core and
   targets.
 
 - Update MAINTAINERS with my kernel.org email address to allow
   distinction between my "upstream" and "Red" Hats.

Linus Torvalds 85c7000fda The highlights are:
- several changes to how snap context and snap realms are tracked
   (Xiubo Li).  In particular, this should resolve a long-standing
   issue of high kworker CPU usage and various stalls caused by
   needless iteration over all inodes in the snap realm.
 
 - async create fixes to address hangs in some edge cases (Jeff Layton)
 
 - support for getvxattr MDS op for querying server-side xattrs, such
   as file/directory layouts and ephemeral pins (Milind Changire)
 
 - average latency is now maintained for all metrics (Venky Shankar)
 
 - some tweaks around handling inline data to make it fit better with
   netfs helper library (David Howells)
 
 Also a couple of memory leaks got plugged along with a few assorted
 fixups.  Last but not least, Xiubo has stepped up to serve as a CephFS
 co-maintainer.

2022-03-24 16:19:43 -07:00
Linus Torvalds 169e77764a Networking changes for 5.18.
Core
 ----
 
  - Introduce XDP multi-buffer support, allowing the use of XDP with
    jumbo frame MTUs and combination with Rx coalescing offloads (LRO).
 
  - Speed up netns dismantling (5x) and lower the memory cost a little.
    Remove unnecessary per-netns sockets. Scope some lists to a netns.
    Cut down RCU syncing. Use batch methods. Allow netdev registration
    to complete out of order.
 
  - Support distinguishing timestamp types (ingress vs egress) and
    maintaining them across packet scrubbing points (e.g. redirect).
 
  - Continue the work of annotating packet drop reasons throughout
    the stack.
 
  - Switch netdev error counters from an atomic to dynamically
    allocated per-CPU counters.
 
  - Rework a few preempt_disable(), local_irq_save() and busy waiting
    sections problematic on PREEMPT_RT.
 
  - Extend the ref_tracker to allow catching use-after-free bugs.
 
 BPF
 ---
 
  - Introduce "packing allocator" for BPF JIT images. JITed code is
    marked read only, and used to be allocated at page granularity.
    Custom allocator allows for more efficient memory use, lower
    iTLB pressure and prevents identity mapping huge pages from
    getting split.
 
  - Make use of BTF type annotations (e.g. __user, __percpu) to enforce
    the correct probe read access method, add appropriate helpers.
 
  - Convert the BPF preload to use light skeleton and drop
    the user-mode-driver dependency.
 
  - Allow XDP BPF_PROG_RUN test infra to send real packets, enabling
    its use as a packet generator.
 
  - Allow local storage memory to be allocated with GFP_KERNEL if called
    from a hook allowed to sleep.
 
  - Introduce fprobe (multi kprobe) to speed up mass attachment (arch
    bits to come later).
 
  - Add unstable conntrack lookup helpers for BPF by using the BPF
    kfunc infra.
 
  - Allow cgroup BPF progs to return custom errors to user space.
 
  - Add support for AF_UNIX iterator batching.
 
  - Allow iterator programs to use sleepable helpers.
 
  - Support JIT of add, and, or, xor and xchg atomic ops on arm64.
 
  - Add BTFGen support to bpftool which allows to use CO-RE in kernels
    without BTF info.
 
  - Large number of libbpf API improvements, cleanups and deprecations.
 
 Protocols
 ---------
 
  - Micro-optimize UDPv6 Tx, gaining up to 5% in test on dummy netdev.
 
  - Adjust TSO packet sizes based on min_rtt, allowing very low latency
    links (data centers) to always send full-sized TSO super-frames.
 
  - Make IPv6 flow label changes (AKA hash rethink) more configurable,
    via sysctl and setsockopt. Distinguish between server and client
    behavior.
 
  - VxLAN support to "collect metadata" devices to terminate only
    configured VNIs. This is similar to VLAN filtering in the bridge.
 
  - Support inserting IPv6 IOAM information to a fraction of frames.
 
  - Add protocol attribute to IP addresses to allow identifying where
    given address comes from (kernel-generated, DHCP etc.)
 
  - Support setting socket and IPv6 options via cmsg on ping6 sockets.
 
  - Reject mis-use of ECN bits in IP headers as part of DSCP/TOS.
    Define dscp_t and stop taking ECN bits into account in fib-rules.
 
  - Add support for locked bridge ports (for 802.1X).
 
  - tun: support NAPI for packets received from batched XDP buffs,
    doubling the performance in some scenarios.
 
  - IPv6 extension header handling in Open vSwitch.
 
  - Support IPv6 control message load balancing in bonding, prevent
    neighbor solicitation and advertisement from using the wrong port.
    Support NS/NA monitor selection similar to existing ARP monitor.
 
  - SMC
    - improve performance with TCP_CORK and sendfile()
    - support auto-corking
    - support TCP_NODELAY
 
  - MCTP (Management Component Transport Protocol)
    - add user space tag control interface
    - I2C binding driver (as specified by DMTF DSP0237)
 
  - Multi-BSSID beacon handling in AP mode for WiFi.
 
  - Bluetooth:
    - handle MSFT Monitor Device Event
    - add MGMT Adv Monitor Device Found/Lost events
 
  - Multi-Path TCP:
    - add support for the SO_SNDTIMEO socket option
    - lots of selftest cleanups and improvements
 
  - Increase the max PDU size in CAN ISOTP to 64 kB.
 
 Driver API
 ----------
 
  - Add HW counters for SW netdevs, a mechanism for devices which
    offload packet forwarding to report packet statistics back to
    software interfaces such as tunnels.
 
  - Select the default NIC queue count as a fraction of number of
    physical CPU cores, instead of hard-coding to 8.
 
  - Expose devlink instance locks to drivers. Allow device layer of
    drivers to use that lock directly instead of creating their own
    which always runs into ordering issues in devlink callbacks.
 
  - Add header/data split indication to guide user space enabling
    of TCP zero-copy Rx.
 
  - Allow configuring completion queue event size.
 
  - Refactor page_pool to enable fragmenting after allocation.
 
  - Add allocation and page reuse statistics to page_pool.
 
  - Improve Multiple Spanning Trees support in the bridge to allow
    reuse of topologies across VLANs, saving HW resources in switches.
 
  - DSA (Distributed Switch Architecture):
    - replay and offload of host VLAN entries
    - offload of static and local FDB entries on LAG interfaces
    - FDB isolation and unicast filtering

Pull networking updates from Jakub Kicinski:
 "The sprinkling of SPI drivers is because we added a new one and Mark
  sent us a SPI driver interface conversion pull request.

  Core
  ----

   - Introduce XDP multi-buffer support, allowing the use of XDP with
     jumbo frame MTUs and combination with Rx coalescing offloads (LRO).

   - Speed up netns dismantling (5x) and lower the memory cost a little.
     Remove unnecessary per-netns sockets. Scope some lists to a netns.
     Cut down RCU syncing. Use batch methods. Allow netdev registration
     to complete out of order.

   - Support distinguishing timestamp types (ingress vs egress) and
     maintaining them across packet scrubbing points (e.g. redirect).

   - Continue the work of annotating packet drop reasons throughout the
     stack.

   - Switch netdev error counters from an atomic to dynamically
     allocated per-CPU counters.

   - Rework a few preempt_disable(), local_irq_save() and busy waiting
     sections problematic on PREEMPT_RT.

   - Extend the ref_tracker to allow catching use-after-free bugs.

  BPF
  ---

   - Introduce "packing allocator" for BPF JIT images. JITed code is
     marked read only, and used to be allocated at page granularity.
     Custom allocator allows for more efficient memory use, lower iTLB
     pressure and prevents identity mapping huge pages from getting
     split.

   - Make use of BTF type annotations (e.g. __user, __percpu) to enforce
     the correct probe read access method, add appropriate helpers.

   - Convert the BPF preload to use light skeleton and drop the
     user-mode-driver dependency.

   - Allow XDP BPF_PROG_RUN test infra to send real packets, enabling
     its use as a packet generator.

   - Allow local storage memory to be allocated with GFP_KERNEL if
     called from a hook allowed to sleep.

   - Introduce fprobe (multi kprobe) to speed up mass attachment (arch
     bits to come later).

   - Add unstable conntrack lookup helpers for BPF by using the BPF
     kfunc infra.

   - Allow cgroup BPF progs to return custom errors to user space.

   - Add support for AF_UNIX iterator batching.

   - Allow iterator programs to use sleepable helpers.

   - Support JIT of add, and, or, xor and xchg atomic ops on arm64.

   - Add BTFGen support to bpftool which allows to use CO-RE in kernels
     without BTF info.

   - Large number of libbpf API improvements, cleanups and deprecations.

  Protocols
  ---------

   - Micro-optimize UDPv6 Tx, gaining up to 5% in test on dummy netdev.

   - Adjust TSO packet sizes based on min_rtt, allowing very low latency
     links (data centers) to always send full-sized TSO super-frames.

   - Make IPv6 flow label changes (AKA hash rethink) more configurable,
     via sysctl and setsockopt. Distinguish between server and client
     behavior.

   - VxLAN support to "collect metadata" devices to terminate only
     configured VNIs. This is similar to VLAN filtering in the bridge.

   - Support inserting IPv6 IOAM information to a fraction of frames.

   - Add protocol attribute to IP addresses to allow identifying where
     given address comes from (kernel-generated, DHCP etc.)

   - Support setting socket and IPv6 options via cmsg on ping6 sockets.

   - Reject mis-use of ECN bits in IP headers as part of DSCP/TOS.
     Define dscp_t and stop taking ECN bits into account in fib-rules.

   - Add support for locked bridge ports (for 802.1X).

   - tun: support NAPI for packets received from batched XDP buffs,
     doubling the performance in some scenarios.

   - IPv6 extension header handling in Open vSwitch.

   - Support IPv6 control message load balancing in bonding, prevent
     neighbor solicitation and advertisement from using the wrong port.
     Support NS/NA monitor selection similar to existing ARP monitor.

   - SMC
      - improve performance with TCP_CORK and sendfile()
      - support auto-corking
      - support TCP_NODELAY

   - MCTP (Management Component Transport Protocol)
      - add user space tag control interface
      - I2C binding driver (as specified by DMTF DSP0237)

   - Multi-BSSID beacon handling in AP mode for WiFi.

   - Bluetooth:
      - handle MSFT Monitor Device Event
      - add MGMT Adv Monitor Device Found/Lost events

   - Multi-Path TCP:
      - add support for the SO_SNDTIMEO socket option
      - lots of selftest cleanups and improvements

   - Increase the max PDU size in CAN ISOTP to 64 kB.

  Driver API
  ----------

   - Add HW counters for SW netdevs, a mechanism for devices which
     offload packet forwarding to report packet statistics back to
     software interfaces such as tunnels.

   - Select the default NIC queue count as a fraction of number of
     physical CPU cores, instead of hard-coding to 8.

   - Expose devlink instance locks to drivers. Allow device layer of
     drivers to use that lock directly instead of creating their own
     which always runs into ordering issues in devlink callbacks.

   - Add header/data split indication to guide user space enabling of
     TCP zero-copy Rx.

   - Allow configuring completion queue event size.

   - Refactor page_pool to enable fragmenting after allocation.

   - Add allocation and page reuse statistics to page_pool.

   - Improve Multiple Spanning Trees support in the bridge to allow
     reuse of topologies across VLANs, saving HW resources in switches.

   - DSA (Distributed Switch Architecture):
      - replay and offload of host VLAN entries
      - offload of static and local FDB entries on LAG interfaces
      - FDB isolation and unicast filtering

Linus Torvalds ed4643521e ARM: DT updates for 5.18
After a somewhat quiet 5.17 release, the size of the DT changes
 is a bit larger again. There are nine new SoC that get added,
 all of them related to existing platforms:
 
  - Airoha (formerly Mediatek/EcoNet) EN7523 networking SoC and EVB
 
  - Mediatek mt6582 tablet platform with the Prestigio PMT5008 3G tablet
 
  - Microchip Lan966 networking SoC and it evaluation board
 
  - Qualcomm Snapdragon 625/632 midrange phone SoCs, with the
    LG Nexus 5X and Fairphone FP3 phones
 
  - Renesas RZ/G2LC and RZ/V2L general-purpose embedded SoCs,
    along with their evaluation boards
 
  - Samsung Exynos 850 phone SoC and reference board
 
  - Samsung Exynos7885 with the Samsung Galaxy A8 (2018) phone
 
  - Tesla FSD (Fully Self-Driving), an automotive SoC losely derived
    from the Samsung Exynos family.
 
  - TI K3/AM62 SoC and reference board
 
 Support for additional functionality in existing dts files is added all
 over the place: Samsung, Renesas, Mstar, wpcm450, OMAP, AT91, Allwinner,
 i.MX, Tegra, Aspeed, Oxnas, Qualcomm, Mediatek, and Broadcom.
 
 Samsung has a rework for its pinctrl schema that is a bit tricky and
 requires driver changes to be included here.
 
 A few more platforms only have smaller cleanups and DT Schema fixes,
 this includes SoCFPGA, ux500, ixp4xx, STi, Xilinx Zynq, LG, and Juno.
 
 The new machines are really too many to list, but I'll do it anyway:
 
  Allwinner:
    - A20-Marsboard development board
 
  Amlogic
   - Amediatek X96-AIR (Amlogic S905X3)
   - CYX A95XF3-AIR (Amlogic S905X3)
   - Haochuangy H96-Max (Amlogic S905X3)
   - Amlogic AQ222 (Amlogic S4)
   - OSMC Vero 4K+ (Amlogic S905D)
 
  Arm Juno
   - Separate DT depending on SCMI firmware version
 
  Aspeed:
   - Quanta S6Q BMC (AST2600)

   - Miyoo Mini handheld game console
 
  NXP i.MX:
   - Numerous i.MX8M Mini based boards in even more variations, but
     none based on other SoCs this time:
     Protonic PRT8MM, emCON-MX8M Mini, Toradex Verdin, and
     Gateworks GW7903
 
  Qualcomm:
   - Google Herobrine R1 Chromebook platform (Snapdragon 7c Gen 3)

Linus Torvalds baaa68a979 ARM: SoC updates for 5.18
SoC specific code is generally used for older platforms that don't (yet)
 use device tree to do the same things.
 
  - Support is added for i.MXRT10xx, a Cortex-M7 based microcontroller
    from NXP. At the moment this is still incomplete as other portions
    are merged through different trees.
 
  - Long abandoned support for running NOMMU ARMv4 or ARMv5 platforms
    gets removed, now the Arm NOMMU platforms are limited to the
    Cortex-M family of microcontrollers
 
  - Two old PXA boards get removed, along with corresponding driver
    bits.
 
  - Continued cleanup of the Intel IXP4xx platforms, removing some
    remnants of the old board files.
 
  - Minor Cleanups and fixes for Orion, PXA, MMP, Mstar, Samsung
 
  - CPU idle support for AT91
 
  - A system controller driver for Polarfire

Linus Torvalds 194dfe88d6 asm-generic updates for 5.18
There are three sets of updates for 5.18 in the asm-generic tree:
 
  - The set_fs()/get_fs() infrastructure gets removed for good. This
    was already gone from all major architectures, but now we can
    finally remove it everywhere, which loses some particularly
    tricky and error-prone code.
    There is a small merge conflict against a parisc cleanup, the
    solution is to use their new version.
 
  - The nds32 architecture ends its tenure in the Linux kernel. The
    hardware is still used and the code is in reasonable shape, but
    the mainline port is not actively maintained any more, as all
    remaining users are thought to run vendor kernels that would never
    be updated to a future release.
    There are some obvious conflicts against changes to the removed
    files.
 
  - A series from Masahiro Yamada cleans up some of the uapi header
    files to pass the compile-time checks.

Rafał Miłecki 5db1c2dbc0 dt-bindings: nvmem: add U-Boot environment variables binding
U-Boot uses environment variables for storing device setup data. It
usually needs to be accessed by a bootloader, kernel and often
user-space.

This binding allows describing environment data located in a raw flash
partition. It's treated as NVMEM device and can be reused later for
other storage devices.

Using DT should be cleaner than hardcoding & duplicating such info in
multiple places. Bootloader & kernel can share DTS and user-space can
try reading it too or just have correct data exposed by a kernel.

A custom "compatible" string allows system to automatically load
relevant NVMEM driver but phandle can be also used for reading raw
location.

Lukas Bulwahn 11cddee9c1 MAINTAINERS: remove section LIBNVDIMM BLK: MMIO-APERTURE DRIVER
Commit f8669f1d6a ("nvdimm/blk: Delete the block-aperture window driver")
removes the file drivers/nvdimm/blk.c, but misses to adjust MAINTAINERS.

Hence, ./scripts/get_maintainer.pl --self-test=patterns complains about a
broken reference.

The section LIBNVDIMM BLK: MMIO-APERTURE DRIVER refers to the driver in
blk.c, and some more generic nvdimm code in region_devs.c.

As the driver is deleted, delete the section LIBNVDIMM BLK: MMIO-APERTURE
DRIVER in MAINTAINERS as well.

The remaining file region_devs.c is still covered by the section LIBNVDIMM:
NON-VOLATILE MEMORY DEVICE SUBSYSTEM, and all patches to region_devs.c will
still reach the same developers as before.

Linus Torvalds ad9c6ee642 spi: Updates for v5.18
The overwhelming bulk of this pull request is a change from Uwe
 Kleine-König which changes the return type of the remove() function to
 void as part of some wider work he's doing to do this for all bus types,
 causing updates to most SPI device drivers.  The branch with that on has
 been cross merged with a couple of other trees which added new SPI
 drivers this cycle, I'm not expecting any build issues resulting from
 the change.
 
 Otherwise it's been a relatively quiet release with some new device
 support, a few minor features and the welcome completion of the
 conversion of the subsystem to use GPIO descriptors rather than numbers:
 
  - Change return type of remove() to void.
  - Completion of the conversion of SPI controller drivers to use GPIO
    descriptors rather than numbers.
  - Quite a few DT schema conversions.
  - Support for multiple SPI devices on a bus in ACPI systems.
  - Big overhaul of the PXA2xx SPI driver.
  - Support for AMD AMDI0062, Intel Raptor Lake, Mediatek MT7986 and
    MT8186, nVidia Tegra210 and Tegra234, Renesas RZ/V2L, Tesla FSD and
    Sunplus SP7021.

Pull random number generator updates from Jason Donenfeld:
 "There have been a few important changes to the RNG's crypto, but the
  intent for 5.18 has been to shore up the existing design as much as
  possible with modern cryptographic functions and proven constructions,
  rather than actually changing up anything fundamental to the RNG's
  design.

  So it's still the same old RNG at its core as before: it still counts
  entropy bits, and collects from the various sources with the same
  heuristics as before, and so forth. However, the cryptographic
  algorithms that transform that entropic data into safe random numbers
  have been modernized.

  Just as important, if not more, is that the code has been cleaned up
  and re-documented. As one of the first drivers in Linux, going back to
  1.3.30, its general style and organization was showing its age and
  becoming both a maintenance burden and an auditability impediment.

  Hopefully this provides a more solid foundation to build on for the
  future. I encourage you to open up the file in full, and maybe you'll
  remark, "oh, that's what it's doing," and enjoy reading it. That, at
  least, is the eventual goal, which this pull begins working toward.

  Here's a summary of the various patches in this pull:

   - /dev/urandom and /dev/random now do the same thing, per the patch
     we discussed on the list. I think this is worth trying out. If it
     does appear problematic, I've made sure to keep it standalone and
     revertible without any conflicts.

   - Fixes and cleanups for numerous integer type problems, locking
     issues, and general code quality concerns.

   - The input pool's LFSR has been replaced with a cryptographically
     secure hash function, which has security and performance benefits
     alike, and consequently allows us to count entropy bits linearly.

   - The pre-init injection now uses a real hash function too, instead
     of an LFSR or vanilla xor.

   - The interrupt handler's fast_mix() function now uses one round of
     SipHash, rather than the fake crypto that was there before.

   - All additions of RDRAND and RDSEED now go through the input pool's
     hash function, in part to mitigate ridiculous hypothetical CPU
     backdoors, but more so to have a consistent interface for ingesting
     entropy that's easy to analyze, making everything happen one way,
     instead of a potpourri of different ways.

   - The crng now works on per-cpu data, while also being in accordance
     with the actual "fast key erasure RNG" design. This allows us to
     fix several boot-time race complications associated with the prior
     dynamically allocated model, eliminates much locking, and makes our
     backtrack protection more robust.

   - Batched entropy now erases doled out values so that it's backtrack
     resistant.

   - Working closely with Sebastian, the interrupt handler no longer
     needs to take any locks at all, as we punt the
     synchronized/expensive operations to a workqueue. This is
     especially nice for PREEMPT_RT, where taking spinlocks in irq
     context is problematic. It also makes the handler faster for the
     rest of us.

   - Also working with Sebastian, we now do the right thing on CPU
     hotplug, so that we don't use stale entropy or fail to accumulate
     new entropy when CPUs come back online.

   - We handle virtual machines that fork / clone / snapshot, using the
     "vmgenid" ACPI specification for retrieving a unique new RNG seed,
     which we can use to also make WireGuard (and in the future, other
     things) safe across VM forks.

   - Around boot time, we now try to reseed more often if enough entropy
     is available, before settling on the usual 5 minute schedule.

   - Last, but certainly not least, the documentation in the file has
     been updated considerably"

Pull power management updates from Rafael Wysocki:
 "These are mostly fixes and cleanups all over the code and a new piece
  of documentation for Intel uncore frequency scaling.

  Functionality-wise, the intel_idle driver will support Sapphire Rapids
  Xeons natively now (with some extra facilities for controlling
  C-states more precisely on those systems), virtual guests will take
  the ACPI S4 hardware signature into account by default, the
  intel_pstate driver will take the defualt EPP value from the firmware,
  cpupower utility will support the AMD P-state driver added in the
  previous cycle, and there is a new tracer utility for that driver.

  Specifics:

   - Allow device_pm_check_callbacks() to be called from interrupt
     context without issues (Dmitry Baryshkov).

   - Modify devm_pm_runtime_enable() to automatically handle
     pm_runtime_dont_use_autosuspend() at driver exit time (Douglas
     Anderson).

   - Make the schedutil cpufreq governor use to_gov_attr_set() instead
     of open coding it (Kevin Hao).

   - Replace acpi_bus_get_device() with acpi_fetch_acpi_dev() in the
     cpufreq longhaul driver (Rafael Wysocki).

   - Unify show() and store() naming in cpufreq and make it use
     __ATTR_XX (Lianjie Zhang).

   - Make the intel_pstate driver use the EPP value set by the firmware
     by default (Srinivas Pandruvada).

   - Re-order the init checks in the powernow-k8 cpufreq driver (Mario
     Limonciello).

   - Make the ACPI processor idle driver check for architectural support
     for LPI to avoid using it on x86 by mistake (Mario Limonciello).

   - Add Sapphire Rapids Xeon support to the intel_idle driver (Artem
     Bityutskiy).

   - Add 'preferred_cstates' module argument to the intel_idle driver to
     work around C1 and C1E handling issue on Sapphire Rapids (Artem
     Bityutskiy).

   - Add core C6 optimization on Sapphire Rapids to the intel_idle
     driver (Artem Bityutskiy).

   - Optimize the haltpoll cpuidle driver a bit (Li RongQing).

   - Remove leftover text from intel_idle() kerneldoc comment and fix up
     white space in intel_idle (Rafael Wysocki).

   - Fix load_image_and_restore() error path (Ye Bin).

   - Fix typos in comments in the system wakeup hadling code (Tom Rix).

   - Clean up non-kernel-doc comments in hibernation code (Jiapeng
     Chong).

   - Fix __setup handler error handling in system-wide suspend and
     hibernation core code (Randy Dunlap).

   - Add device name to suspend_report_result() (Youngjin Jang).

   - Make virtual guests honour ACPI S4 hardware signature by default
     (David Woodhouse).

   - Block power off of a parent PM domain unless child is in deepest
     state (Ulf Hansson).

   - Use dev_err_probe() to simplify error handling for generic PM
     domains (Ahmad Fatoum).

   - Fix sleep-in-atomic bug caused by genpd_debug_remove() (Shawn Guo).

   - Document Intel uncore frequency scaling (Srinivas Pandruvada).

   - Add DTPM hierarchy description (Daniel Lezcano).

   - Change the locking scheme in DTPM (Daniel Lezcano).

   - Fix dtpm_cpu cleanup at exit time and missing virtual DTPM pointer
     release (Daniel Lezcano).

   - Make dtpm_node_callback[] static (kernel test robot).

   - Fix spelling mistake "initialze" -> "initialize" in
     dtpm_create_hierarchy() (Colin Ian King).

   - Add tracer tool for the amd-pstate driver (Jinzhou Su).

   - Fix PC6 displaying in turbostat on some systems (Artem Bityutskiy).

   - Add AMD P-State support to the cpupower utility (Huang Rui)"

ASoC: Updates for v5.18

Quite a quiet release for ASoC, lots of work on drivers and platforms
but nothing too groundbreaking but not much on the core itself:

 - Start of moving SoF to support multiple IPC mechanisms.
 - Use of NHLT ACPI table to reduce the amount of quirking required for
   Intel systems.
 - Some building blocks for use in forthcoming Intel AVS driver for
   legacy Intel DSP firmwares.
 - Support for AMD PDM, Atmel PDMC, Awinic AW8738, i.MX cards with
   TLV320AIC31xx, Intel machines with CS35L41 and ESSX8336, Mediatek
   MT8181 wideband bluetooth, nVidia Tegra234, Qualcomm SC7280, Renesas
   RZ/V2L, Texas Instruments TAS585M

Markuss Broks a23ba3c043 Input: add Imagis touchscreen driver
Add support for the IST3038C touchscreen IC from Imagis, based on
downstream driver. The driver supports multi-touch (10 touch points)
The IST3038C IC supports touch keys, but the support isn't added
because the touch screen used for testing doesn't utilize touch keys.
Looking at the downstream driver, it is possible to add support
for other Imagis ICs of IST30**C series.

Greg Kroah-Hartman cc6ce5ac2c First set of new device support, fixes, cleanups and features for IIO in 5.18
This cycle we had quite a few series that applied similar changes
 to lots of drivers. To keep this description manageable I have
 called those out in their own section rather than per driver.
 
 Particularly pleased to see the long running AFE precision series
 going in this cycle.
 
 Series includes some late breaking fixes.
 
 New device support
 * adi,ada4250 amplifier
   - New driver and dt bindings for this programmable gain amplifier.
 * adi,admv1014 microwave down-converter
   - New driver, dt bindings and some device specific ABI that
     may be generalized as more drivers for devices similar to this
     are added.
 * adi,admv4420 K Band down-converter.
   - New driver and dt bindings.
 * adi,adxl367 accelerometer driver.
   - New driver, dt-bindings + some new IIO ABI definitions to support
     reference magnitude events where an estimate of the acceleration
     due to gravity has been removed.
   - A few fixes as follow up patches.
 * adi,ltc2688 DAC with toggle and dither modes.
   - New driver and bindings. Includes some new driver specific (for now)
     ABI for handling toggle mode and the addition of a dither waveform to
     the DAC output.
 * AFE (analog front end) add support for additional types of analog device
   in front of an ADC.
   - RTD temperature sensors with dt bindings.
   - Temperature transducers wit dt bindings.
   - Related cleanup and features listed in other sections below.
 * maxim,ds3502 potentiometer.
   - Add support to ds1803 driver which required significant rework.
 * mediatek,mt2701-auxadc driver
   - Add mediatek,mt8186-auxadc - id table and chip specific info only.
 * semtech,sx9324, semtech,ax9360
   - Substantial refactoring of sx9310 to extract core logic for reuse
     into a separate module
   - New driver using this supporting sx9324 proximity sensors.
   - New driver using this supporting sx9360 proximity sensors.
 * silan,sc7a20
   - Compatible with the st,lis2dh (or nearly anyway) so add ID and
     chip specific info to enable support. Also silan vendor ID added
     for dt-bindings.
 
 Staging graduation
 * adi,ad7280a monitoring ADC for stacked lithium-ion batteries in
   electric cars and similar.
   - Substantial rework of driver required to bring inline with current
     IIO best practice. An unusual device in IIO so some interesting features
     we may see more of in future.
 
 Multiple driver/core cleanup
 - Use sysfs_emit() in simple locations where there is no path to change
   to various core created attributes.
 - Trivial white space fixes around inconsistency between space after { and
   before } in id tables.
 - Introduce new handling for fractional types to avoid repeated similar
   implementations. Use this in 3 drivers. Note this is also targeted
   at future use in the AFE driver and was motivated by discussions
   around the precision related work on that driver.
 - of related header cleanups - drop of*.h and add mod_devicetable.h as
   appropriate.
 - Move a number of symbol exports into IIO_* namespaces.  Two categories,
   1) Library used by multiple drivers e.g. st_sensors
   2) Core driver module exporting functions used by bus specific modules.
   A few related cleanups in this set.
 - Switch from CONFIG_PM_* guards to new DEFINE_SIMPLE_DEV_PM_OPS() and
   similar to simplify drivers and take advantage of these new macros
   allowing the compiler to do the job or removing unused code without
   the need for __maybe_unused markings. Conversion of other drivers to
   these new macros ongoing.
 
 Features
 * adi,adf4350
   - Switch from of specific to generic device properties enabling use with
     other firmware types.
 * adi,adx345
   - Switch from of specific to generic device properties.
   - Add ACPI ID ADS0345
   - Related driver cleanup.

     ever access.
   - Use struct_size() rather than open coding in industrialio-hw-consumer
 * adi,axl355
   - Use units.h definitions instead of local versions.
 * adi,adis-lib
   - Simplify *updated_bits() macro
   - Whitespace cleanup.
 * afe - Note many of these fixes only apply to particular configurations
   so the problems have probably not been seen in the wild, but will be
   visible with new usecases enabled this cycle.
   - Fix application of consumer scale for IIO_VAL_INT.
   - Apply a scale of 1 when no scale is provided.
   - Make best effort to establish a valid offset value for fractional

Pratyush Yadav 8148baabd1 media: platform: re-structure TI drivers
The ti-vpe/ sub-directory does not only contain the VPE-specific things.
It also contains the CAL driver, which is a completely different
subsystem. This is also not a good place to add new drivers for other TI
platforms since they will all get mixed up.

Separate the VPE and CAL parts into different sub-directories and rename
the ti-vpe/ sub-directory to ti/. This is now the place where new TI
platform drivers can be added.

Jonathan Neuschäfer a1d1e0e3d8 pinctrl: nuvoton: Add driver for WPCM450
This driver is based on the one for NPCM7xx, because the WPCM450 is a
predecessor of those SoCs. Notable differences:

- On WPCM450, the GPIO registers are not organized in multiple banks,
  but rather placed continually into the same register block. This
  affects how register offsets are computed.
- Pinmux nodes can explicitly select GPIO mode, whereas in the npcm7xx
  driver, this happens automatically when a GPIO is requested.

Some functionality implemented in the hardware was (for now) left unused
in the driver, specifically blinking and pull-up/down.

Ioana Ciornei 8f73b37cf3 phy: add support for the Layerscape SerDes 28G
This patch adds a new generic PHY driver to support the Lynx 28G SerDes
block found on some of the Layerscape SoCs such as LX2160A.
At the moment, only the following Ethernet protocols are supported:
SGMII/1000Base-X and 10GBaseR.

SerDes lanes which are not running an Ethernet protocol or a currently
supported Ethenet protocol will be left as it was configured through the
RCW (Reset Configuration Word) at boot time.

At probe time, the platform driver will read the current
configuration of both PLLs found on a SerDes block and will determine
what protocols are supported using that PLL.

For example, if a PLL is configured to generate a clock net (frate) of
5GHz the only protocols sustained by that PLL are SGMII/1000Base-X
(using a quarter of the full clock rate) and QSGMII using the full clock
net frequency on the lane.

On the .set_mode() callback, the PHY driver will first check if the

Jason A. Donenfeld af6b54e2b5 virt: vmgenid: notify RNG of VM fork and supply generation ID
VM Generation ID is a feature from Microsoft, described at
<https://go.microsoft.com/fwlink/?LinkId=260709>, and supported by
Hyper-V and QEMU. Its usage is described in Microsoft's RNG whitepaper,
<https://aka.ms/win10rng>, as:

    If the OS is running in a VM, there is a problem that most
    hypervisors can snapshot the state of the machine and later rewind
    the VM state to the saved state. This results in the machine running
    a second time with the exact same RNG state, which leads to serious
    security problems.  To reduce the window of vulnerability, Windows
    10 on a Hyper-V VM will detect when the VM state is reset, retrieve
    a unique (not random) value from the hypervisor, and reseed the root
    RNG with that unique value.  This does not eliminate the
    vulnerability, but it greatly reduces the time during which the RNG
    system will produce the same outputs as it did during a previous
    instantiation of the same VM state.

Linux has the same issue, and given that vmgenid is supported already by
multiple hypervisors, we can implement more or less the same solution.
So this commit wires up the vmgenid ACPI notification to the RNG's newly
added add_vmfork_randomness() function.

It can be used from qemu via the `-device vmgenid,guid=auto` parameter.
After setting that, use `savevm` in the monitor to save the VM state,
then quit QEMU, start it again, and use `loadvm`. That will trigger this
driver's notify function, which hands the new UUID to the RNG. This is
described in <https://git.qemu.org/?p=qemu.git;a=blob;f=docs/specs/vmgenid.txt>.
And there are hooks for this in libvirt as well, described in
<https://libvirt.org/formatdomain.html#general-metadata>.

Note, however, that the treatment of this as a UUID is considered to be
an accidental QEMU nuance, per
<https://github.com/libguestfs/virt-v2v/blob/master/docs/vm-generation-id-across-hypervisors.txt>,
so this driver simply treats these bytes as an opaque 128-bit binary
blob, as per the spec. This doesn't really make a difference anyway,
considering that's how it ends up when handed to the RNG in the end.

Commit 0e5f897708 ("dt-bindings: Remove Netlogic bindings") removes the

Hence, ./scripts/get_maintainer.pl --self-test=patterns complains about a

Remove the file reference to i2c-xlp9xx.txt in XLP9XX I2C DRIVER.

As commit ef99066c7d ("i2c: Remove Netlogic XLP variant") explains, the
i2c-xlp9xx driver is still used by the Cavium ThunderX2 platform. So, keep

Hector Martin ab1fd5abb7 dt-bindings: interrupt-controller: apple,aic2: New binding for AICv2
This new incompatible revision of the AIC peripheral introduces
multi-die support. This binding is based on apple,aic, but
changes interrupt-cells to add a new die argument.

Also adds a second reg entry to specify the offset of the event
register. Inexplicably, the capability registers allow us to compute
other register offsets, but not this one. This allows us to keep
forward-compatibility with future SoCs that will likely implement
different die counts, thus shifting the event register. Apple also
specify the offset explicitly in their device tree...

cpuidle: Add RISC-V SBI CPU idle driver
The RISC-V SBI HSM extension provides HSM suspend call which can
be used by Linux RISC-V to enter platform specific low-power state.

This patch adds a CPU idle driver based on RISC-V SBI calls which
will populate idle states from device tree and use SBI calls to
entry these idle states.

Alan Kao aec499c75c nds32: Remove the architecture
The nds32 architecture, also known as AndeStar V3, is a custom 32-bit
RISC target designed by Andes Technologies. Support was added to the
kernel in 2016 as the replacement RISC-V based V5 processors were
already announced, and maintained by (current or former) Andes
employees.

As explained by Alan Kao, new customers are now all using RISC-V,
and all known nds32 users are already on longterm stable kernels
provided by Andes, with no development work going into mainline
support any more.

While the port is still in a reasonably good shape, it only gets
worse over time without active maintainers, so it seems best
to remove it before it becomes unusable. As always, if it turns
out that there are mainline users after all, and they volunteer
to maintain the port in the future, the removal can be reverted.

Samuel Holland 75853406fa power: supply: Add a driver for Injoinic power bank ICs
This driver supports several chip variants which all share the same I2C
register interface. Since the chip will turn off and become inaccessible
under conditions outside of software control (e.g. upon button press or
input voltage removal), some special handling is needed to delay the
initialization of the IC until it is accessible.

Add driver for the Intersil ISL7998x Analog to MIPI CSI-2/BT656 decoder.
This chip supports 1/2/4 analog video inputs and converts them into
1/2/4 VCs in MIPI CSI2 stream.

This driver currently supports ISL79987 and both 720x480 and 720x576
resolutions, however as per specification, all inputs must use the
same resolution and standard. The only supported pixel format is now
YUYV/YUV422. The chip should support RGB565 on the CSI2 as well, but
this is currently unsupported.

Yishai Hadas 6fadb02126 vfio/mlx5: Implement vfio_pci driver for mlx5 devices
This patch adds support for vfio_pci driver for mlx5 devices.

It uses vfio_pci_core to register to the VFIO subsystem and then
implements the mlx5 specific logic in the migration area.

The migration implementation follows the definition from uapi/vfio.h and
uses the mlx5 VF->PF command channel to achieve it.

This patch implements the suspend/resume flows.

set of mailbox registers.

More details on the interface can be found in chapter
"7 Host System Management Port (HSMP)" of the following PPR
https://www.amd.com/system/files/TechDocs/55898_B1_pub_0.50.zip

This patch adds new amd_hsmp module under the drivers/platforms/x86/
which creates miscdevice with an IOCTL interface to the user space.
/dev/hsmp is for running the hsmp mailbox commands.

    handling and compilation
 
  - Fix a clock disabling imbalance in gpcv2 driver.
 
  - Arm Juno DMA coherency issue
 
  - Trivial firmware driver fixes for op-tee and scmi firmware
 
 The remaining changes address issues in the devicetree files:

    the alternative timer.
 
  - A hang in the i.MX8MM power domain configuration
 
  - Multiple fixes for the Rockchip RK3399 addressing issues
    with sound and eMMC

drm/tiny: Add MIPI DBI compatible SPI driver
Add a driver that will work with most MIPI DBI compatible SPI panels.
This avoids adding a driver for every new MIPI DBI compatible controller
that is to be used by Linux. The 'compatible' Device Tree property with
a '.bin' suffix will be used to load a firmware file that contains the
controller configuration.

Example (driver will load sainsmart18.bin):

display@0 {
	compatible = "sainsmart18", "panel-mipi-dbi-spi";
...
};

v5:
- kconfig: s/DRM_KMS_CMA_HELPER/DRM_GEM_CMA_HELPER/ (Sam)
- kconfig: Add select VIDEOMODE_HELPERS (Sam)
- kconfig: Add wiki url in the description (Sam)
- Split out and use of_get_drm_panel_display_mode()(Sam)
- Only use the first compatible to look for a firmware file since the
  binding mandates 2 compatibles.
- Make having a firmware file mandatory so we can print an error
  message if it's missing to improve the user experience. It's very
  unlikely that a controller doesn't need to be initialized and if
  it doesn't, it's possible to have a firmware file containing only
  a DCS NOP.

v4:
- Move driver to drm/tiny where the other drivers of its kind are located.
  The driver module will not be shared with a future DPI driver after all.

v3:
- Move properties to DT (Maxime)
- The MIPI DPI spec has optional support for DPI where the controller is
  configured over DBI. Rework the command functions so they can be moved
  to drm_mipi_dbi and shared with a future panel-mipi-dpi-spi driver

v2:
- Drop model property and use compatible instead (Rob)
- Add wiki entry in MAINTAINERS

Eugene Shalygin d0ddfd241e hwmon: (asus-ec-sensors) add driver for ASUS EC
This driver provides the same data as the asus_wmi_ec_sensors driver
(and gets it from the same source) but does not use WMI, polling
the ACPI EC directly.

That provides two enhancements: sensor reading became quicker (on some
systems or kernel configuration it took almost a full second to read
all the sensors, that transfers less than 15 bytes of data), the driver
became more flexible. The driver now relies on ACPI mutex to lock access
to the EC in the same way as the WMI code does.

Arnd Bergmann 4d9b86eb38 Samsung pinctrl DTS and driver changes for v5.18
Conversion of Samsung pinctrl bindings to dtschema followed up with
 alignment of DTS files to the dtschema.
 
 The entire work consists of three parts but everything should be merged
 at once to avoid dtschema check errors:
 1. Samsung pinctrl driver change necessary to accept new DTS (driver
    depends on node names and this has to be adjusted because of dtschema).
 2. Conversion to dtschema which brings requirement of different naming
    of the GPIO nodes.
 3. DTS commits depending on driver (1) above, which convert all GPIO pin
    bank names to new naming, required by dtschema.
    This also includes few cleanups around DTS which are here to avoid
    any merge conflicts.
 
 The Samsung pinctrl driver changes are backwards compatible.  However
 the DTS changes (renaming nodes) could cause problems in out-of-tree or
 other project implementations of the driver.

Thorsten Leemhuis 1ecf393fc5 docs: add two documents about regression handling
Create two documents explaining various aspects around regression
handling and tracking; one is aimed at users, the other targets
developers.

The texts among others describes the first rule of Linux kernel
development and what it means in practice. They also explain what a
regression actually is and how to report one properly.

Both texts additionally provide a brief introduction to the bot the
kernel's regression tracker uses to facilitate the work, but mention the
use is optional.

To sum things up, provide a few quotes from Linus in the document for
developers to show how serious we take regressions.

Rename the imx7-mipi-csis.c driver to remove the reference to i.MX7.

The driver is for an IP core found on i.MX7 and i.MX8 SoC, so do not
specify a SoC version number in the driver name.

Remove the references to the i.MX7 SoC in the driver symbols and expand
the driver's header with more information about the IP core the driver
controls.

Also rename the associated bindings documentation.

Cosmin Tanislav cbab791c5e iio: accel: add ADXL367 driver
The ADXL367 is an ultralow power, 3-axis MEMS accelerometer.

The ADXL367 does not alias input signals to achieve ultralow power
consumption, it samples the full bandwidth of the sensor at all
data rates. Measurement ranges of +-2g, +-4g, and +-8g are available,
with a resolution of 0.25mg/LSB on the +-2 g range.

In addition to its ultralow power consumption, the ADXL367
has many features to enable true system level power reduction.
It includes a deep multimode output FIFO, a built-in micropower
temperature sensor, and an internal ADC for synchronous conversion
of an additional analog input.

David E. Box 2546c60004 platform/x86: Add Intel Software Defined Silicon driver
Intel Software Defined Silicon (SDSi) is a post manufacturing mechanism for
activating additional silicon features. Features are enabled through a
license activation process.  The SDSi driver provides a per socket, sysfs
attribute interface for applications to perform 3 main provisioning
functions:

1. Provision an Authentication Key Certificate (AKC), a key written to
   internal NVRAM that is used to authenticate a capability specific
   activation payload.

2. Provision a Capability Activation Payload (CAP), a token authenticated
   using the AKC and applied to the CPU configuration to activate a new
   feature.

3. Read the SDSi State Certificate, containing the CPU configuration
   state.

The operations perform function specific mailbox commands that forward the
requests to SDSi hardware to perform authentication of the payloads and
enable the silicon configuration (to be made available after power
cycling).

The SDSi device itself is enumerated as an auxiliary device from the
intel_vsec driver and as such has a build dependency on CONFIG_INTEL_VSEC.

Linus Torvalds 83e3966411 ARM: SoC fixes for 5.17
This is a fairly large set of bugfixes, most of which had
 been sent a while ago but only now made it into the soc tree:
 
 Maintainer file updates:
 
  - Claudiu Beznea now co-maintains the at91 soc family,
    replacing Ludovic Desroches.
 
  - Michael Walle maintains the sl28cpld drivers
 
  - Alain Volmat and Raphael Gallais-Pou take over some
    drivers for ST platforms
 
  - Alim Akhtar is an additional reviewer for Samsung platforms
 
 Code fixes:
 
  - Op-tee had a problem with object lifetime that needs
    a slightly complex fix, as well as another bug with
    error handling.
 
  - Several minor issues for the OMAP platform, including
    a regression with the timer
 
  - A Kconfig change to fix a build-time issue on Intel
    SoCFPGA
 
 Device tree fixes:
 
  - The Amlogic Meson platform fixes a boot regression on
    am1-odroid, a spurious interrupt, and a problem with
    reserved memory regions
 
  - In the i.MX platform, several bug fixes are needed to
    make devices work correctly: SD card detection,
    alarmtimer, and sound card on some board. One patch
    for the GPU got in there by accident and gets reverted
    again.
 
  - TI K3 needs a fix for J721S2 serial port numbers
 
  - ux500 needs a fix to mount the SD card as root on
    the Skomer phone.
