      devlink: trivial names cleanup
      
      This is a follow-up to Jakub's devlink code split and dump iteration
      helper patchset. No functional changes, just couple of renames to makes
      things consistent and perhaps easier to follow.

      devlink: rename and reorder instances of struct devlink_cmd · 8589ba4e
      Jiri Pirko authored
      In order to maintain naming consistency, rename and reorder all usages
      of struct struct devlink_cmd in the following way:
      1) Remove "gen" and replace it with "cmd" to match the struct name
      2) Order devl_cmds[] and the header file to match the order
         of enum devlink_command
      3) Move devl_cmd_rate_get among the peers
      4) Remove "inst" for DEVLINK_CMD_GET
      5) Add "_get" suffix to all to match DEVLINK_CMD_*_GET (only rate had it
         done correctly)

      ====================
      net: ipa: remaining IPA v5.0 support
      
      This series includes almost all remaining IPA code changes required
      to support IPA v5.0.  IPA register definitions and configuration
      data for IPA v5.0 will be sent later (soon).  Note that the GSI
      register definitions still require work.  GSI for IPA v5.0 supports
      up to 256 (rather than 32) channels, and this changes the way GSI
      register offsets are calculated.  A few GSI register fields also
      change.
      
      The first patch in this series increases the number of IPA endpoints
      supported by the driver, from 32 to 36.  The next updates the width
      of the destination field for the IP_PACKET_INIT immediate command so
      it can represent up to 256 endpoints rather than just 32.  The next
      adds a few definitions of some IPA registers and fields that are
      first available in IPA v5.0.
      
      The next two patches update the code that handles router and filter
      table caches.  Previously these were referred to as "hashed" tables,
      and the IPv4 and IPv6 tables are now combined into one "unified"
      table.  The sixth and seventh patches add support for a new pulse
      generator, which allows time periods to be specified with a wider
      range of clock resolution.  And the last patch just defines two new
      memory regions that were not previously used.

      net: ipa: support a third pulse register · 2cdbcbfd
      Alex Elder authored
      The AP has third pulse generator available starting with IPA v5.0.
      Redefine ipa_qtime_val() to support that possibility.  Pass the IPA
      pointer as an argument so the version can be determined.  And stop
      using the sign of the returned tick count to indicate which of two
      pulse generators to use.
      
      Instead, have the caller provide the address of a variable that will
      hold the selected pulse generator for the Qtime value.  And for
      version 5.0, check whether the third pulse generator best represents
      the time period.
      
      Add code in ipa_qtime_config() to configure the fourth pulse
      generator for IPA v5.0+; in that case configure both the third and
      fourth pulse generators to use 10 msec granularity.
      
      Consistently use "ticks" for local variables that represent a tick
      count.

      net: ipa: greater timer granularity options · 32079a4a
      Alex Elder authored
      Starting with IPA v5.0, the head-of-line blocking timer has more
      than two pulse generators available to define timer granularity.
      To prepare for that, change the way the field value is encoded
      to use ipa_reg_encode() rather than ipa_reg_bit().
      
      The aggregation granularity selection could (in principle) also use
      an additional pulse generator starting with IPA v5.0.  Encode the
      AGGR_GRAN_SEL field differently to allow that as well.

      net: ipa: support zeroing new cache tables · a08cedc3
      Alex Elder authored
      IPA v5.0+ separates the configuration of entries in the cached
      (previously "hashed") routing and filtering tables into distinct
      registers.  Previously a single "filter and router" register updated
      entries in both tables at once; now the routing and filter table
      caches have separate registers that define their content.
      
      This patch updates the code that zeroes entries in the cached filter
      and router tables to support IPA versions including v5.0+.

      Alex Elder authored
      Define some new registers that appear starting with IPA v5.0, along
      with enumerated types identifying their fields.  Code that uses
      these will be added by upcoming patches.
      
      Most of the new registers are related to filter and routing tables,
      and in particular, their "hashed" variant.  These tables are better
      described as "cached", where a hash value determines which entries
      are cached.  From now on, naming related to this functionality will
      use "cache" instead of "hash", and that is reflected in these new
      register names.  Some registers for managing these caches and their
      contents have changed as well.
      
      A few other new field definitions for registers (unrelated to table
      caches) are also defined.

      net: ipa: support more endpoints · 07abde54
      Alex Elder authored
      Increase the number of endpoints supported by the driver to 36,
      which IPA v5.0 supports.  This makes it impossible to check at build
      time whether the supported number is too big to fit within the
      (5-bit) PACKET_INIT destination endpoint field.  Instead, convert
      the build time check to compare against what fits in 8 bits.
      
      Add a check in ipa_endpoint_config() to also ensure the hardware
      reports an endpoint count that's in the expected range.  Just
      open-code 32 as the limit (the PACKET_INIT field mask is not
      available where we'd want to use it).

      ====================
      mlx5-updates-2023-01-30
      
      Add fast update encryption key
      
      Jianbo Liu Says:
      ================
      
      Data encryption keys (DEKs) are the keys used for data encryption and
      decryption operations. Starting from version 22.33.0783, firmware is
      optimized to accelerate the update of user keys into DEK object in
      hardware. The support for bulk allocation and destruction of DEK
      objects is added, and the bulk allocated DEKs are uninitialized, as
      the bulk creation requires no input key. When offload
      encryption/decryption, user gets one object from a bulk, and updates
      key by a new "modify DEK" command. This command is the same as create
      DEK object, but requires no heavy context memory allocation in
      firmware, which consumes most cpu cycles of the create DEK command.
      
      DEKs are cached internally by the NIC, so invalidating internal NIC
      caches is required before reusing DEKs. The SYNC_CRYPTO command is
      added to support it. DEK object can be reused, the keys in it can be
      updated after this command is executed.
      
      This patchset enhances the key creation and destruction flow, to get
      use of this new feature. Any user, for example, ktls, ipsec and
      macsec, can use it to offload keys. But, only ktls uses it, as others
      don't need many keys, and caching two many DEKs in pool is wasteful.
      
      There are two new data struts added:
          a. DEK pool. One pool is created for each key type. The bulks by
      the type, are placed in the pool's different bulk lists, according to
      the number of available and in_used DEKs in the bulk.
          b. DEK bulk. All DEKs in one bulk allocation are store here. There
      are two bitmaps to indicate the state of each DEK.
      
      New APIs are then added. When user need a DEK object,
          a. Fetch one bulk with avail DEKs, from the partial_list or
      avail_list, otherwise create new one.
          b. Pick one DEK, and set its need_sync and in_used bits to 1.
      Move the bulk to full_list if no more available keys, or put it to
      partial_list if the bulk is newly created.
          c. Update DEK object's key with user key, by the "modify DEK"
      command.
          d. Return DEK struct to user, then it gets the object id and fills
      it into the offload commands.
      When user free a DEK,
          a. Set in_use bit to 0. If all need_sync bits are 1 and all in_use
      bits of this bulk are 0, move it to sync_list.
          b. If the number of DEKs, which are freed by users, is over the
      threshold (128), schedule a workqueue to do the sync process.
      
      For the sync process, the SYNC_CRYPTO command is executed first. Then,
      for each bulks in partial_list, full_list and sync_list, reset
      need_sync bits of the freed DEK objects. If all need_sync bits in one
      bulk are zero, move it to avail_list.
      
      We already supported TIS pool to recycle the TISes. With this series
      and TIS pool, TLS CPS performance is improved greatly.
      And we tested https on the system:
          CPU: dual AMD EPYC 7763 64-Core processors
          RAM: 512G
          DEV: ConnectX-6 DX, with FW ver 22.33.0838 and TLS_OPTIMISE=true
      TLS CPS performance numbers are:
          Before: 11k connections/sec
          After: 101 connections/sec

      ====================
      net: mdio: add amlogic gxl mdio mux support
      
      Add support for the MDIO multiplexer found in the Amlogic GXL SoC family.
      This multiplexer allows to choose between the external (SoC pins) MDIO bus,
      or the internal one leading to the integrated 10/100M PHY.
      
      This multiplexer has been handled with the mdio-mux-mmioreg generic driver
      so far. When it was added, it was thought the logic was handled by a
      single register.
      
      It turns out more than a single register need to be properly set.
      As long as the device is using the Amlogic vendor bootloader, or upstream
      u-boot with net support, it is working fine since the kernel is inheriting
      the bootloader settings. Without net support in the bootloader, this glue
      comes unset in the kernel and only the external path may operate properly.
      
      With this driver (and the associated change in
      arch/arm64/boot/dts/amlogic/meson-gxl.dtsi), the kernel no longer relies
      on the bootloader to set things up, fixing the problem.

      ====================
      tools: ynl: more docs and basic ethtool support
      
      I got discouraged from supporting ethtool in specs, because
      generating the user space C code seems a little tricky.
      The messages are ID'ed in a "directional" way (to and from
      kernel are separate ID "spaces"). There is value, however,
      in having the spec and being able to for example use it
      in Python.
      
      After paying off some technical debt - add a partial
      ethtool spec. Partial because the header for ethtool is almost
      a 1000 LoC, so converting in one sitting is tough. But adding
      new commands should be trivial now.
      
      Last but not least I add more docs, I realized that I've been
      sending a similar "instructions" email to people working on
      new families. It's now intro-specs.rst.

      netlink: specs: add partial specification for ethtool · b784db7a
      Jakub Kicinski authored
      Ethtool is one of the most actively developed families.
      With the changes to the CLI it should be possible to use
      the YNL based code for easy prototyping and development.
      Add a partial family definition. I've tested the string
      set and rings. I don't have any MAC Merge implementation
      to test with, but I added the definition for it, anyway,
      because it's last. New commands can simply be added at
      the end without having to worry about manually providing
      IDs / values.
      
      Set (with notification support - None is the response,
      the data is from the notification):
      
      $ sudo ./tools/net/ynl/cli.py \
          --spec Documentation/netlink/specs/ethtool.yaml \
          --do rings-set \
          --json '{"header":{"dev-name":"enp0s31f6"}, "rx":129}' \
          --subscribe monitor
      None
      [{'msg': {'header': {'dev-index': 2, 'dev-name': 'enp0s31f6'},
                'rx': 136,
                'rx-max': 4096,
                'tx': 256,
                'tx-max': 4096,
                'tx-push': 0},
        'name': 'rings-ntf'}]
      
      Do / dump (yes, the kernel requires that even for dump and even
      if empty - the "header" nest must be there):
      
      $ ./tools/net/ynl/cli.py \
          --spec Documentation/netlink/specs/ethtool.yaml \
          --do rings-get \
          --json '{"header":{"dev-index": 2}}'
      {'header': {'dev-index': 2, 'dev-name': 'enp0s31f6'},
       'rx': 136,
       'rx-max': 4096,
       'tx': 256,
       'tx-max': 4096,
       'tx-push': 0}
      
      $ ./tools/net/ynl/cli.py \
          --spec Documentation/netlink/specs/ethtool.yaml \
          --dump rings-get \
          --json '{"header":{}}'
      [{'header': {'dev-index': 2, 'dev-name': 'enp0s31f6'},
        'rx': 136,
        'rx-max': 4096,
        'tx': 256,
        'tx-max': 4096,
        'tx-push': 0},
       {'header': {'dev-index': 3, 'dev-name': 'wlp0s20f3'}, 'tx-push': 0},
       {'header': {'dev-index': 19, 'dev-name': 'enp58s0u1u1'},
        'rx': 100,
        'rx-max': 4096,
        'tx-push': 0}]
      
      And error reporting:
      
      $ ./tools/net/ynl/cli.py \
          --spec Documentation/netlink/specs/ethtool.yaml \
          --dump rings-get \

      netlink: specs: finish up operation enum-models · 8403bf04
      Jakub Kicinski authored
      I had a (bright?) idea of introducing the concept of enum-models
      to account for all the weird ways families enumerate their messages.
      I've never finished it because generating C code for each of them
      is pretty daunting. But for languages which can use ID values directly
      the support is simple enough, so clean this up a bit.
      
      "unified" model is what I recommend going forward.
      "directional" model is what ethtool uses.
      "notify-split" is used by the proposed DPLL code, but we can just
      make them use "unified", it hasn't been merged :)

      Jakub Kicinski authored
      The CLI script tries to validate jsonschema by default.
      It's seems better to validate too many times than too few.
      However, when copying the scripts to random servers having
      to install jsonschema is tedious. Load jsonschema via
      importlib, and let the user opt out.

      tools: ynl: use operation names from spec on the CLI · 8dfec0a8
      Jakub Kicinski authored
      When I wrote the first version of the Python code I was quite
      excited that we can generate class methods directly from the
      spec. Unfortunately we need to use valid identifiers for method
      names (specifically no dashes are allowed). Don't reuse those
      names on the CLI, it's much more natural to use the operation
      names exactly as listed in the spec.
      
      Instead of:
        ./cli --do rings_get
      use:
        ./cli --do rings-get

      tools: ynl: support pretty printing bad attribute names · 4cd2796f
      Jakub Kicinski authored
      One of my favorite features of the Netlink specs is that they
      make decoding structured extack a ton easier.
      Implement pretty printing bad attribute names in YNL.
      
      For example it will now say:
      
        'bad-attr': '.header.flags'
      
      rather than the useless:
      
        'bad-attr-offs': 32
      
      Proof:
      
        $ ./cli.py --spec ethtool.yaml --do rings_get \
           --json '{"header":{"dev-index":1, "flags":4}}'
        Netlink error: Invalid argument
        nl_len = 68 (52) nl_flags = 0x300 nl_type = 2
