      afs: Fix afs_getattr() to refetch file status if callback break occurred · 2aeb8c86
      David Howells authored
      If a callback break occurs (change notification), afs_getattr() needs to
      issue an FS.FetchStatus RPC operation to update the status of the file
      being examined by the stat-family of system calls.
      
      Fix afs_getattr() to do this if AFS_VNODE_CB_PROMISED has been cleared
      on a vnode by a callback break.  Skip this if AT_STATX_DONT_SYNC is set.
      
      This can be tested by appending to a file on one AFS client and then
      using "stat -L" to examine its length on a machine running kafs.  This
      can also be watched through tracing on the kafs machine.  The callback
      break is seen:
      
           kworker/1:1-46      [001] .....   978.910812: afs_cb_call: c=0000005f YFSCB.CallBack
           kworker/1:1-46      [001] ...1.   978.910829: afs_cb_break: 100058:23b4c:242d2c2 b=2 s=1 break-cb
           kworker/1:1-46      [001] .....   978.911062: afs_call_done:    c=0000005f ret=0 ab=0 [0000000082994ead]
      
      And then the stat command generated no traffic if unpatched, but with
      this ...

      perf session: Fix Intel LBR callstack entries and nr print message · 51d0bf99
      Chengdong Li authored and Arnaldo Melo's avatar Arnaldo Melo committed
      
      
      When generating callstack information from branch_stack(Intel LBR), the
      actual number of callstack entry should be bigger than the number of
      branch_stack, for example:
      
      	branch_stack records:
      		B() -> C()
      		A() -> B()
      	converted callstack records should be:
      		C()
      		B()
      		A()
      though, the number of callstack equals
      to the number of branch stack plus 1.
      
      This patch fixes above issue in branch_stack__printf(). For example,
      
      	# echo 'scale=2000; 4*a(1)' > cmd
      	# perf record --call-graph lbr bc -l < cmd

      perf test bpf: Skip test if clang is not present · 8994e97b

      Perf BPF filter test fails in environment where "clang" is not
      installed.

      <<>>
      
      Here subtests, "BPF pinning" and "BPF prologue generation" failed and
      logs shows clang/llvm is needed. After installing clang, testcase
      passes.
      
      Reason on why subtest failure happens though logs has proper debug
      information:
      
      Main function __test__bpf calls test_llvm__fetch_bpf_obj by
      passing 4th argument as true ( 4th arguments maps to parameter
      "force" in test_llvm__fetch_bpf_obj ). But this will cause
      test_llvm__fetch_bpf_obj to skip the check for clang/llvm.
      
      Snippet of code part which checks for clang based on
      parameter "force" in test_llvm__fetch_bpf_obj:
      
      <<>>
      if (!force && (!llvm_param.user_set_param &&
      <<>>
      
      Since force is set to "false", test won't get skipped and fails to
      compile test case. The BPF code compilation needs clang, So pass the
      fourth argument as "false" and also skip the test if reason for return
      is "TEST_SKIP"
      
      After the patch:
      
      <<>>
       42: BPF filter                    :
       42.1: Basic BPF filtering         : Skip
       42.2: BPF pinning                 : Skip

      The session topology test fails in powerpc pSeries platform.
      
      Test logs:
      
        <<>>
        Session topology : FAILED!
        <<>>
      
      This testcases tests cpu topology by checking the core_id and socket_id
      stored in perf_env from perf session. The data from perf session is
      compared with the cpu topology information from
      "/sys/devices/system/cpu/cpuX/topology" like core_id,
      physical_package_id.
      
      In case of virtual environment, detail like physical_package_id is
      restricted to be exposed. Hence physical_package_id is set to -1. The
      testcase fails on such platforms since socket_id can't be fetched from
      topology info.
      
      Skip the testcase in powerpc if physical_package_id returns -1.

      perf test: Avoid shell test description infinite loop · caaaa554
      Ian Rogers authored and Arnaldo Melo's avatar Arnaldo Melo committed
      
      
      for_each_shell_test() is already strict in expecting tests to be files
      and executable. It is sometimes possible when it iterates over all files
      that it finds one that is executable and lacks a newline character. When
      this happens the loop never terminates as it doesn't check for EOF.
      
      Add the EOF check to make this loop at least bounded by the file size.
      
      If the description is returned as NULL then also skip the test.

      perf regs x86: Fix arch__intr_reg_mask() for the hybrid platform · 01b28e4a
      Kan Liang authored and Arnaldo Melo's avatar Arnaldo Melo committed
      The X86 specific arch__intr_reg_mask() is to check whether the kernel
      and hardware can collect XMM registers. But it doesn't work on some
      hybrid platform.
      
      Without the patch on ADL-N:
      
        $ perf record -I?
        available registers: AX BX CX DX SI DI BP SP IP FLAGS CS SS R8 R9 R10
        R11 R12 R13 R14 R15
      
      The config of the test event doesn't contain the PMU information. The
      kernel may fail to initialize it on the correct hybrid PMU and return
      the wrong non-supported information.
      
      Add the PMU information into the config for the hybrid platform. The
      same register set is supported among different hybrid PMUs. Checking
      the first available one is good enough.
      
      With the patch on ADL-N:
      
        $ perf record -I?
        available registers: AX BX CX DX SI DI BP SP IP FLAGS CS SS R8 R9 R10
        R11 R12 R13 R14 R15 XMM0 XMM1 XMM2 XMM3 XMM4 XMM5 XMM6 XMM7 XMM8 XMM9

      perf test: Fix "all PMU test" to skip hv_24x7/hv_gpci tests on powerpc · 451ed805
      athira-rajeev authored and Arnaldo Melo's avatar Arnaldo Melo committed
      "perf all PMU test" picks the input events from "perf list --raw-dump
      pmu" list and runs "perf stat -e" for each of the event in the list. In
      case of powerpc, the PowerVM environment supports events from hv_24x7
      and hv_gpci PMU which is of example format like below:
      
      - hv_24x7/CPM_ADJUNCT_INST,domain=?,core=?/
      - hv_gpci/event,partition_id=?/
      
      The value for "?" needs to be filled in depending on system and
      respective event. CPM_ADJUNCT_INST needs have core value and domain
      value. hv_gpci event needs partition_id.  Similarly, there are other
      events for hv_24x7 and hv_gpci having "?" in event format. Hence skip
      these events on powerpc platform since values like partition_id, domain
      is specific to system and event.

      i2c: ismt: Provide a DMA buffer for Interrupt Cause Logging · 17a0f3ac
      Mika Westerberg authored and Wolfram Sang's avatar Wolfram Sang committed
      
      
      Before sending a MSI the hardware writes information pertinent to the
      interrupt cause to a memory location pointed by SMTICL register. This
      memory holds three double words where the least significant bit tells
      whether the interrupt cause of master/target/error is valid. The driver
      does not use this but we need to set it up because otherwise it will
      perform DMA write to the default address (0) and this will cause an
      IOMMU fault such as below:
      
        DMAR: DRHD: handling fault status reg 2
        DMAR: [DMA Write] Request device [00:12.0] PASID ffffffff fault addr 0
              [fault reason 05] PTE Write access is not set
      
      To prevent this from happening, provide a proper DMA buffer for this
      that then gets mapped by the IOMMU accordingly.
