      ASoC: SOF: Intel: hda-mlink: fix sublink refcounting · 7430dea4
      Pierre-Louis Bossart authored
      In hindsight it was a very bad idea to use the same refcount for
      Extended and 'legacy' HDaudio multi-links. The existing solution only
      powers-up the first sublink, which causes SoundWire and SSP tests to
      fail when more than one DAI is used concurrently. Solving this problem
      requires per-sublink refcounting, as suggested in this patch.
      
      The existing refcounting remains for 'legacy' HdAudio links, mainly to
      avoid changing the obscure programming sequence in
      snd_hdac_ext_bus_link_put().

      ASoC: ssm2602: Add workaround for playback distortions · f63550e2
      Paweł Anikiel authored
      Apply a workaround for what appears to be a hardware quirk.
      
      The problem seems to happen when enabling "whole chip power" (bit D7
      register R6) for the very first time after the chip receives power. If
      either "output" (D4) or "DAC" (D3) aren't powered on at that time,
      playback becomes very distorted later on.
      
      This happens on the Google Chameleon v3, as well as on a ZYBO Z7-10:
      https://ez.analog.com/audio/f/q-a/543726/solved-ssm2603-right-output-offset-issue/480229
      I suspect this happens only when using an external MCLK signal (which
      is the case for both of these boards).
      
      Here are some experiments run on a Google Chameleon v3. These were run
      in userspace using a wrapper around the i2cset utility:
      ssmset() {
              i2cset -y 0 0x1a $(($1*2)) $2
      }
      
      For each of the following sequences, we apply power to the ssm2603
      chip, set the configuration registers R0-R5 and R7-R8, run the selected
      sequence, and check for distortions on playback.
      
        ssmset 0x09 0x01 # core
        ssmset 0x06 0x07 # chip, out, dac

        ssmset 0x06 0x17 # chip, dac
        ssmset 0x06 0x07 # out
        NOT OK
      
      For each of the following sequences, we apply power to the ssm2603
      chip, run the selected sequence, issue a reset with R15, configure
      R0-R5 and R7-R8, run one of the NOT OK sequences from above, and check
      for distortions.
      
        ssmset 0x09 0x01 # core
        ssmset 0x06 0x07 # chip, out, dac

      ASoC: dt-bindings: Adjust #sound-dai-cells on TI's single-DAI codecs · efb2bfd7
      Martin Povišer authored
      A bunch of TI's codecs have binding schemas which force #sound-dai-cells
      to one despite those codecs only having a single DAI. Allow for bindings
      with zero DAI cells and deprecate the former non-zero value.

      ASoC: jz4740-i2s: Make I2S divider calculations more robust · ad721bc9
      Aidan MacDonald authored
      When the CPU supplies bit/frame clocks, the system clock (clk_i2s)
      is divided to produce the bit clock. This is a simple 1/N divider
      with a fairly limited range, so for a given system clock frequency
      only a few sample rates can be produced. Usually a wider range of
      sample rates is supported by varying the system clock frequency.
      
      The old calculation method was not very robust and could easily
      produce the wrong clock rate, especially with non-standard rates.
      For example, if the system clock is 1.99x the target bit clock
      rate, the divider would be calculated as 1 instead of the more
      accurate 2.
      
      Instead, use a more accurate method that considers two adjacent
      divider settings and selects the one that produces the least error
      versus the requested rate. If the error is 5% or higher then the
      rate setting is rejected to prevent garbled audio.
      
      Skip divider calculation when the codec is supplying both the bit
      and frame clock; in that case, the divider outputs are unused and
      we don't want to constrain the sample rate.

      Merge tag 'perf-tools-for-v6.4-3-2023-05-06' of git://git.kernel.org/pub/scm/linux/kernel/git/acme/linux
      
      Pull perf tool updates from Arnaldo Carvalho de Melo:
       "Third version of perf tool updates, with the build problems with with
        using a 'vmlinux.h' generated from the main build fixed, and the bpf
        skeleton build disabled by default.
      
        Build:
      
         - Require libtraceevent to build, one can disable it using
           NO_LIBTRACEEVENT=1.
      
           It is required for tools like 'perf sched', 'perf kvm', 'perf
           trace', etc.
      
           libtraceevent is available in most distros so installing
           'libtraceevent-devel' should be a one-time event to continue
           building perf as usual.
      
           Using NO_LIBTRACEEVENT=1 produces tooling that is functional and
           sufficient for lots of users not interested in those libtraceevent
           dependent features.
      
         - Allow Python support in 'perf script' when libtraceevent isn't
           linked, as not all features requires it, for instance Intel PT does
           not use tracepoints.
      
         - Error if the python interpreter needed for jevents to work isn't
           available and NO_JEVENTS=1 isn't set, preventing a build without
           support for JSON vendor events, which is a rare but possible
           condition. The two check error messages:
      
              $(error ERROR: No python interpreter needed for jevents generation. Install python or build with NO_JEVENTS=1.)
              $(error ERROR: Python interpreter needed for jevents generation too old (older than 3.6). Install a newer python or build with NO_JEVENTS=1.)
      
         - Make libbpf 1.0 the minimum required when building with out of
           tree, distro provided libbpf.
      
         - Use libsdtc++'s and LLVM's libcxx's __cxa_demangle, a portable C++
           demangler, add 'perf test' entry for it.
      
         - Make binutils libraries opt in, as distros disable building with it
           due to licensing, they were used for C++ demangling, for instance.
      
         - Switch libpfm4 to opt-out rather than opt-in, if libpfm-devel (or
           equivalent) isn't installed, we'll just have a build warning:
      
             Makefile.config:1144: libpfm4 not found, disables libpfm4 support. Please install libpfm4-dev
      
         - Add a feature test for scandirat(), that is not implemented so far
           in musl and uclibc, disabling features that need it, such as
           scanning for tracepoints in /sys/kernel/tracing/events.
      
        perf BPF filters:
      
         - New feature where BPF can be used to filter samples, for instance:
      
            $ sudo ./perf record -e cycles --filter 'period > 1000' true
            $ sudo ./perf script

         - In addition to 'period' (PERF_SAMPLE_PERIOD), the other
           PERF_SAMPLE_ can be used for filtering, and also some other sample
           accessible values, from tools/perf/Documentation/perf-record.txt:
      
              Essentially the BPF filter expression is:
      
              <term> <operator> <value> (("," | "||") <term> <operator> <value>)*
      
           The <term> can be one of:
              ip, id, tid, pid, cpu, time, addr, period, txn, weight, phys_addr,
              code_pgsz, data_pgsz, weight1, weight2, weight3, ins_lat, retire_lat,
              p_stage_cyc, mem_op, mem_lvl, mem_snoop, mem_remote, mem_lock,
              mem_dtlb, mem_blk, mem_hops
      
           The <operator> can be one of:
              ==, !=, >, >=, <, <=, &
      
           The <value> can be one of:
              <number> (for any term)
              na, load, store, pfetch, exec (for mem_op)
              l1, l2, l3, l4, cxl, io, any_cache, lfb, ram, pmem (for mem_lvl)
              na, none, hit, miss, hitm, fwd, peer (for mem_snoop)
              remote (for mem_remote)
              na, locked (for mem_locked)
              na, l1_hit, l1_miss, l2_hit, l2_miss, any_hit, any_miss, walk, fault (for mem_dtlb)
              na, by_data, by_addr (for mem_blk)

        perf top:
      
         - Add --branch-history (LBR: Last Branch Record) option, just like
           already available for 'perf record'.
      
         - Fix segfault in thread__comm_len() where thread->comm was being
           used outside thread->comm_lock.
      
        perf annotate:
      
         - Allow configuring objdump and addr2line in ~/.perfconfig., so that
           you can use alternative binaries, such as llvm's.
      
        perf kvm:
      
         - Add TUI mode for 'perf kvm stat report'.
      
        Reference counting:
      
         - Add reference count checking infrastructure to check for use after
           free, done to the 'cpumap', 'namespaces', 'maps' and 'map' structs,
           more to come.
      
           To build with it use -DREFCNT_CHECKING=1 in the make command line
           to build tools/perf. Documented at:
      
             https://perf.wiki.kernel.org/index.php/Reference_Count_Checking
      
         - The above caught, for instance, fix, present in this series:
      
              - Fix maps use after put in 'perf test "Share thread maps"':
      
                'maps' is copied from leader, but the leader is put on line 79
                and then 'maps' is used to read the reference count below - so
                a use after put, with the put of maps happening within
                thread__put.
      
           Fixed by reversing the order of puts so that the leader is put
           last.
      
         - Also several fixes were made to places where reference counts were
           not being held.
      
         - Make this one of the tests in 'make -C tools/perf build-test' to
           regularly build test it and to make sure no direct access to the
           reference counted structs are made, doing that via accessors to
           check the validity of the struct pointer.
      
        ARM64:
      
         - Fix 'perf report' segfault when filtering coresight traces by
           sparse lists of CPUs.
      
         - Add support for 'simd' as a sort field for 'perf report', to show
           ARM's NEON SIMD's predicate flags: "partial" and "empty".
      
        arm64 vendor events:
      
         - Add N1 metrics.
      
        Intel vendor events:
      
         - Add graniterapids, grandridge and sierraforrest events.
      
         - Refresh events for: alderlake, aldernaken, broadwell, broadwellde,
           broadwellx, cascadelakx, haswell, haswellx, icelake, icelakex,
           jaketown, meteorlake, knightslanding, sandybridge, sapphirerapids,
           silvermont, skylake, tigerlake and westmereep-dp
      
         - Refresh metrics for alderlake-n, broadwell, broadwellde,
           broadwellx, haswell, haswellx, icelakex, ivybridge, ivytown and
           skylakex.
      
        perf stat:
      
         - Implement --topdown using JSON metrics.
      
         - Add TopdownL1 JSON metric as a default if present, but disable it
           for now for some Intel hybrid architectures, a series of patches
           addressing this is being reviewed and will be submitted for v6.5.
      
         - Use metrics for --smi-cost.
      
         - Update topdown documentation.
      
        Vendor events (JSON) infrastructure:
      
         - Add support for computing and printing metric threshold values. For
           instance, here is one found in thesapphirerapids json file:
      
             {
                 "BriefDescription": "Percentage of cycles spent in System Management Interrupts.",
                 "MetricExpr": "((msr@aperf@ - cycles) / msr@aperf@ if msr@smi@ > 0 else 0)",
                 "MetricGroup": "smi",
                 "MetricName": "smi_cycles",
                 "MetricThreshold": "smi_cycles > 0.1",
                 "ScaleUnit": "100%"
             },
      
         - Test parsing metric thresholds with the fake PMU in 'perf test
           pmu-events'.
      
         - Support for printing metric thresholds in 'perf list'.
      
         - Add --metric-no-threshold option to 'perf stat'.
      
         - Add rand (reverse and) and has_pmem (optane memory) support to
           metrics.
      
         - Sort list of input files to avoid depending on the order from
           readdir() helping in obtaining reproducible builds.
      
        S/390:
      
         - Add common metrics: - CPI (cycles per instruction), prbstate (ratio
           of instructions executed in problem state compared to total number
           of instructions), l1mp (Level one instruction and data cache misses
           per 100 instructions).
      
         - Add cache metrics for z13, z14, z15 and z16.
      
         - Add metric for TLB and cache.
      
        ARM:
      
         - Add raw decoding for SPE (Statistical Profiling Extension) v1.3 MTE
           (Memory Tagging Extension) and MOPS (Memory Operations) load/store.
      
        Intel PT hardware tracing:
      
         - Add event type names UINTR (User interrupt delivered) and UIRET
           (Exiting from user interrupt routine), documented in table 32-50
           "CFE Packet Type and Vector Fields Details" in the Intel Processor
           Trace chapter of The Intel SDM Volume 3 version 078.
      
         - Add support for new branch instructions ERETS and ERETU.
      
         - Fix CYC timestamps after standalone CBR
      
        ARM CoreSight hardware tracing:
      
         - Allow user to override timestamp and contextid settings.
      
         - Fix segfault in dso lookup.
      
         - Fix timeless decode mode detection.
      
         - Add separate decode paths for timeless and per-thread modes.
      
        auxtrace:
      
         - Fix address filter entire kernel size.
      
        Miscellaneous:
      
         - Fix use-after-free and unaligned bugs in the PLT handling routines.
      
         - Use zfree() to reduce chances of use after free.
      
         - Add missing 0x prefix for addresses printed in hexadecimal in 'perf
           probe'.

         - Add support for printing PERF_MEM_LVLNUM_UNC (Uncached access) in
           'perf mem'.
      
         - Fix wrong size expectation for perf test 'Setup struct
           perf_event_attr' caused by the patch adding
           perf_event_attr::config3.

       "A single fix for debugobjects:
      
        The recent fix to ensure atomicity of lookup and allocation
        inadvertently broke the pool refill mechanism, so that debugobject
        OOMs now in certain situations. The reason is that the functions which
        got updated no longer invoke debug_objecs_init(), which is now the
        only place to care about refilling the tracking object pool.
      
        Restore the original behaviour by adding explicit refill opportunities
        to those places"
