<content type='text'>
When clone3() was introduced, it was not obvious how each architecture
deals with setting up the stack and keeping the register contents in
a fork()-like system call, so this was left for the architecture
maintainers to implement, with __ARCH_WANT_SYS_CLONE3 defined by those
that already implement it.

Five years later, we still have a few architectures left that are missing
clone3(), and the macro keeps getting in the way as it's fundamentally
different from all the other __ARCH_WANT_SYS_* macros that are meant
to provide backwards-compatibility with applications using older
syscalls that are no longer provided by default.

Address this by reversing the polarity of the macro, adding an
__ARCH_BROKEN_SYS_CLONE3 macro to all architectures that don't
already provide the syscall, and remove __ARCH_WANT_SYS_CLONE3
from all the other ones.

<title>tools/x86/kcpuid: Add missing dir via Makefile</title>

So far the Makefile just installed the csv into $(HWDATADIR)/cpuid.csv, which
made it unaware about $DESTDIR. Add $DESTDIR to the install command and while
at it also create the directory, should it not exist already. This eases the
packaging of kcpuid and allows i.e. for the install on Arch to look like this:

  $ make BINDIR=/usr/bin DESTDIR="$pkgdir" -C tools/arch/x86/kcpuid install

Some background on DESTDIR:

DESTDIR is commonly used in packaging for staged installs (regardless of the
used package manager):

  https://www.gnu.org/prep/standards/html_node/DESTDIR.html

So the package is built and installed into a directory which the package
manager later picks up and creates some archive from it.

What is specific to Arch Linux here is only the usage of $pkgdir in the
example, DESTDIR itself is widely used.

    coding standards thing. ]

<title>tools headers arm64: Sync arm64's cputype.h with the kernel sources</title>

<id>dc6abbbde4b099e936cd5428e196d86a5e119aae</id>
<content type='text'>
To get the changes in:

  0ce85db6c2141b7f ("arm64: cputype: Add Neoverse-V3 definitions")
  02a0a04676fa7796 ("arm64: cputype: Add Cortex-X4 definitions")
  f4d9d9dcc70b96b5 ("arm64: Add Neoverse-V2 part")

That makes this perf source code to be rebuilt:

  CC      /tmp/build/perf-tools/util/arm-spe.o

The changes in the above patch add MIDR_NEOVERSE_V[23] and
MIDR_NEOVERSE_V1 is used in arm-spe.c, so probably we need to add those
and perhaps MIDR_CORTEX_X4 to that array? Or maybe we need to leave this
for later when this is all tested on those machines?

  static const struct midr_range neoverse_spe[] = {
          MIDR_ALL_VERSIONS(MIDR_NEOVERSE_N1),
          MIDR_ALL_VERSIONS(MIDR_NEOVERSE_N2),
          MIDR_ALL_VERSIONS(MIDR_NEOVERSE_V1),
          {},
  };

Mark Rutland recommended about arm-spe.c:

"I would not touch this for now -- someone would have to go audit the
TRMs to check that those other cores have the same encoding, and I think
it'd be better to do that as a follow-up."

That addresses this perf build warning:

  Warning: Kernel ABI header differences:

          {},
  };

Mark Rutland recommended about arm-spe.c:

"I would not touch this for now -- someone would have to go audit the
TRMs to check that those other cores have the same encoding, and I think
it'd be better to do that as a follow-up."

That addresses this perf build warning:

  Warning: Kernel ABI header differences:

To pick the changes in:

  4af663c2f64a8d25 ("KVM: SEV: Allow per-guest configuration of GHCB protocol version")
  4f5defae708992dd ("KVM: SEV: introduce KVM_SEV_INIT2 operation")
  26c44aa9e076ed83 ("KVM: SEV: define VM types for SEV and SEV-ES")
  ac5c48027bacb1b5 ("KVM: SEV: publish supported VMSA features")
  651d61bc8b7d8bb6 ("KVM: PPC: Fix documentation for ppc mmu caps")

That don't change functionality in tools/perf, as no new ioctl is added
for the 'perf trace' scripts to harvest.

This addresses these perf build warnings:

Pull perf tools updates from Arnaldo Carvalho de Melo:
 "General:

   - Integrate the shellcheck utility with the build of perf to allow
     catching shell problems early in areas such as 'perf test', 'perf
     trace' scrape scripts, etc

   - Add 'uretprobe' variant in the 'perf bench uprobe' tool

   - Add script to run instances of 'perf script' in parallel

   - Allow parsing tracepoint names that start with digits, such as
     9p/9p_client_req, etc. Make sure 'perf test' tests it even on
     systems where those tracepoints aren't available

   - Add Kan Liang to MAINTAINERS as a perf tools reviewer

   - Add support for using the 'capstone' disassembler library in
     various tools, such as 'perf script' and 'perf annotate'. This is
     an alternative for the use of the 'xed' and 'objdump' disassemblers

  Data-type profiling improvements:

   - Resolve types for a-&gt;b-&gt;c by backtracking the assignments until it
     finds DWARF info for one of those members

   - Support for global variables, keeping a cache to speed up lookups

   - Handle the 'call' instruction, dealing with effects on registers
     and handling its return when tracking register data types

   - Handle x86's segment based addressing like %gs:0x28, to support
     things like per CPU variables, the stack canary, etc

   - Data-type profiling got big speedups when using capstone for
     disassembling. The objdump outoput parsing method is left as a
     fallback when capstone fails or isn't available. There are patches
     posted for 6.11 that to use a LLVM disassembler

   - Support event group display in the TUI when annotating types with
     --data-type, for instance to show memory load and store events for
     the data type fields

   - Optimize the 'perf annotate' data structures, reducing memory usage

   - Add a initial 'perf test' for 'perf annotate', checking that a
     target symbol appears on the output, specifying objdump via the
     command line, etc

  Vendor Events:

   - Update Intel JSON files for Cascade Lake X, Emerald Rapids, Grand
     Ridge, Ice Lake X, Lunar Lake, Meteor Lake, Sapphire Rapids, Sierra
     Forest, Sky Lake X, Sky Lake and Snow Ridge X. Remove info metrics
     erroneously in TopdownL1

   - Add AMD's Zen 5 core and uncore events and metrics. Those come from
     the "Performance Monitor Counters for AMD Family 1Ah Model 00h- 0Fh
     Processors" document, with events that capture information on op
     dispatch, execution and retirement, branch prediction, L1 and L2
     cache activity, TLB activity, etc

   - Mark L1D_CACHE_INVAL impacted by errata for ARM64's AmpereOne/
     AmpereOneX

  Miscellaneous:

   - Sync header copies with the kernel sources

   - Move some header copies used only for generating translation string
     tables for ioctl cmds and other syscall integer arguments to a new
     directory under tools/perf/beauty/, to separate from copies in
     tools/include/ that are used to build the tools

   - Introduce scrape script for several syscall 'flags'/'mask'
     arguments

   - Improve cpumap utilization, fixing up pairing of refcounts, using
     the right iterators (perf_cpu_map__for_each_cpu), etc

   - Give more details about raw event encodings in 'perf list', show
     tracepoint encoding in the detailed output

   - Refactor the DSOs handling code, reducing memory usage

   - Document the BPF event modifier and add a 'perf test' for it

   - Improve the event parser, better error messages and add further
     'perf test's for it

   - Add reference count checking to 'struct comm_str' and 'struct
     mem_info'

   - Make ARM64's 'perf test' entries for the Neoverse N1 more robust

   - Tweak the ARM64's Coresight 'perf test's

   - Improve ARM64's CoreSight ETM version detection and error reporting

   - Fix handling of symbols when using kcore

   - Fix PAI (Processor Activity Instrumentation) counter names for s390
     virtual machines in 'perf report'

   - Fix -g/--call-graph option failure in 'perf sched timehist'

   - Add LIBTRACEEVENT_DIR build option to allow building with
     libtraceevent installed in non-standard directories, such as when
     doing cross builds

   - Various 'perf test' and 'perf bench' fixes

   - Improve 'perf probe' error message for long C++ probe names"
