            "32.2.4
      
             Event Trace is a capability that exposes details about the
             asynchronous events, when they are generated, and when their
             corresponding software event handler completes execution. These
             include:
      
              o Interrupts, including NMI and SMI, including the interrupt
                vector when defined.
      
              o Faults, exceptions including the fault vector.
      
                 - Page faults additionally include the page fault address,
                   when in context.
      
              o Event handler returns, including IRET and RSM.
      
              o VM exits and VM entries.¹
      
                 - VM exits include the values written to the “exit reason”
                   and “exit qualification” VMCS fields. INIT and SIPI events.
      
              o TSX aborts, including the abort status returned for the RTM
                instructions.
      
              o Shutdown.
      
             Additionally, it provides indication of the status of the
             Interrupt Flag (IF), to indicate when interrupts are masked"
      
        ARM CoreSight:
      
         - Use advertised caps/min_interval as default sample_period on ARM

        perf stat:
      
         - Fix forked applications enablement of counters.
      
         - The 'slots' should only be printed on a different order than the
           one specified on the command line when 'topdown' events are
           present, fix it.
      
        Miscellaneous:
      
         - Sync msr-index, cpufeatures header files with the kernel sources.

        is limited to 2 instructions (and typically fewer) on branch targets

      Revert "swiotlb: rework "fix info leak with DMA_FROM_DEVICE"" · bddac7c1
      Linus Torvalds authored
      This reverts commit aa6f8dcb.
      
      It turns out this breaks at least the ath9k wireless driver, and
      possibly others.
      
      What the ath9k driver does on packet receive is to set up the DMA
      transfer with:
      
        int ath_rx_init(..)
        ..
                      bf->bf_buf_addr = dma_map_single(sc->dev, skb->data,
                                                       common->rx_bufsize,
                                                       DMA_FROM_DEVICE);
      
      and then the receive logic (through ath_rx_tasklet()) will fetch
      incoming packets
      
        static bool ath_edma_get_buffers(..)
        ..
              dma_sync_single_for_cpu(sc->dev, bf->bf_buf_addr,
                                      common->rx_bufsize, DMA_FROM_DEVICE);
      
              ret = ath9k_hw_process_rxdesc_edma(ah, rs, skb->data);
              if (ret == -EINPROGRESS) {
                      /*let device gain the buffer again*/
                      dma_sync_single_for_device(sc->dev, bf->bf_buf_addr,
                                      common->rx_bufsize, DMA_FROM_DEVICE);
                      return false;
              }
      
      and it's worth noting how that first DMA sync:
      
          dma_sync_single_for_cpu(..DMA_FROM_DEVICE);
      
      is there to make sure the CPU can read the DMA buffer (possibly by
      copying it from the bounce buffer area, or by doing some cache flush).
      The iommu correctly turns that into a "copy from bounce bufer" so that
      the driver can look at the state of the packets.
      
      In the meantime, the device may continue to write to the DMA buffer, but
      we at least have a snapshot of the state due to that first DMA sync.
      
      But that _second_ DMA sync:
      
          dma_sync_single_for_device(..DMA_FROM_DEVICE);
      
      is telling the DMA mapping that the CPU wasn't interested in the area
      because the packet wasn't there.  In the case of a DMA bounce buffer,
      that is a no-op.
      
      Note how it's not a sync for the CPU (the "for_device()" part), and it's
      not a sync for data written by the CPU (the "DMA_FROM_DEVICE" part).
      
      Or rather, it _should_ be a no-op.  That's what commit aa6f8dcb
      broke: it made the code bounce the buffer unconditionally, and changed
      the DMA_FROM_DEVICE to just unconditionally and illogically be
      DMA_TO_DEVICE.
      
      [ Side note: purely within the confines of the swiotlb driver it wasn't
        entirely illogical: The reason it did that odd DMA_FROM_DEVICE ->
        DMA_TO_DEVICE conversion thing is because inside the swiotlb driver,
        it uses just a swiotlb_bounce() helper that doesn't care about the
        whole distinction of who the sync is for - only which direction to
        bounce.
      
        So it took the "sync for device" to mean that the CPU must have been
        the one writing, and thought it meant DMA_TO_DEVICE. ]
      
      Also note how the commentary in that commit was wrong, probably due to
      that whole confusion, claiming that the commit makes the swiotlb code
      
                                        "bounce unconditionally (that is, also
          when dir == DMA_TO_DEVICE) in order do avoid synchronising back stale
          data from the swiotlb buffer"
      
      which is nonsensical for two reasons:
      
       - that "also when dir == DMA_TO_DEVICE" is nonsensical, as that was
         exactly when it always did - and should do - the bounce.
      
       - since this is a sync for the device (not for the CPU), we're clearly
         fundamentally not coping back stale data from the bounce buffers at
         all, because we'd be copying *to* the bounce buffers.
      
      So that commit was just very confused.  It confused the direction of the
      synchronization (to the device, not the cpu) with the direction of the
      DMA (from the device).

      perf tools: Enhance the matching of sub-commands abbreviations · ae0f4eb3
      Wei Li authored
      We support short command 'rec*' for 'record' and 'rep*' for 'report' in
      lots of sub-commands, but the matching is not quite strict currnetly.
      
      It may be puzzling sometime, like we mis-type a 'recport' to report but
      it will perform 'record' in fact without any message.
      
      To fix this, add a check to ensure that the short cmd is valid prefix
      of the real command.

       "Kbuild -std=gnu11 updates for v5.18
      
        Linus pointed out the benefits of C99 some years ago, especially
        variable declarations in loops [1]. At that time, we were not ready
        for the migration due to old compilers.
      
        Recently, Jakob Koschel reported a bug in list_for_each_entry(), which
        leaks the invalid pointer out of the loop [2]. In the discussion, we
        agreed that the time had come. Now that GCC 5.1 is the minimum
        compiler version, there is nothing to prevent us from going to
        -std=gnu99, or even straight to -std=gnu11.
      
        Discussions for a better list iterator implementation are ongoing, but
        this patch set must land first"

      perf lock: Add --synth=no option for record · 67b61f59
      Namhyung Kim authored
      The perf lock command has nothing to symbolize and lock names come
      from the tracepoint.  Moreover, kernel symbols are available even the
      --synth=no option is given.
      
      This will reduce the startup time by avoiding unnecessary synthesis.
