perf tools arm64: Add support for VG register
Add the name of the VG register so it can be used in --user-regs The event will fail to open if the register is requested but not available so only add it to the mask if the kernel supports sve and also if it supports that specific register. Committer notes: Add conditional definition of HWCAP_SVE, as suggested by Leo Yan, to build on older systems where this is not available in the system headers.

perf unwind arm64: Decouple Libunwind register names from Perf
DWARF register numbers and real register numbers on aarch64 are equivalent. Remove the references to the register names from Libunwind so that new registers are supported without having to add build time feature checks for each new register. The unwinder won't ask for a register that it doesn't know about and Perf will already report an error for an unknown or unrecorded register in the perf_reg_value() function so extra validation isn't needed. After this change the new VG register can be read by libunwind.

perf unwind: Use dynamic register set for DWARF unwind
Architectures can detect availability of extra registers at runtime so
use this more complete set for unwinding. This will include the VG
register on arm64 in a later commit.
If the function isn't implemented then PERF_REGS_MASK is returned and
there is no change.
Committer notes:
Added util/perf_regs.c to tools/perf/util/python-ext-sources so that
'perf test python' passes, i.e. the perf python binding has all the
symbols it needs, addressing:
$ perf test -v python
19: 'import perf' in python :
--- start ---
test child forked, pid 2037817
python usage test: "echo "import sys ; sys.path.append('/tmp/build/perf/python'); import perf" | '/usr/bin/python3' "

perf c2c: Use stdio interface if slang is not supported
If the slang lib is not installed on the system, perf c2c tool disables TUI
mode and roll back to use stdio mode; but the flag 'c2c.use_stdio' is
missed to set true and thus it wrongly applies UI quirks in the function
ui_quirks().
This commit forces to use stdio interface if slang is not supported, and
it can avoid to apply the UI quirks and show the correct metric header.

perf record: Add cgroup support for off-cpu profiling
This covers two different use cases. The first one is cgroup
filtering given by -G/--cgroup option which controls the off-cpu
profiling for tasks in the given cgroups only.
The other use case is cgroup sampling which is enabled by
--all-cgroups option and it adds PERF_SAMPLE_CGROUP to the sample_type
to set the cgroup id of the task in the sample data.
Example output.
$ sudo perf record -a --off-cpu --all-cgroups sleep 1
$ sudo perf report --stdio -s comm,cgroup --call-graph=no

perf record: Enable off-cpu analysis with BPF
Add --off-cpu option to enable the off-cpu profiling with BPF. It'd
use a bpf_output event and rename it to "offcpu-time". Samples will
be synthesized at the end of the record session using data from a BPF
map which contains the aggregated off-cpu time at context switches.
So it needs root privilege to get the off-cpu profiling.
Each sample will have a separate user stacktrace so it will skip
kernel threads. The sample ip will be set from the stacktrace and
other sample data will be updated accordingly. Currently it only
handles some basic sample types.
The sample timestamp is set to a dummy value just not to bother with
other events during the sorting. So it has a very big initial value
and increase it on processing each samples.
Good thing is that it can be used together with regular profiling like
cpu cycles. If you don't want to that, you can use a dummy event to
enable off-cpu profiling only.
Example output:
$ sudo perf record --off-cpu perf bench sched messaging -l 1000
$ sudo perf report --stdio --call-graph=no
# Total Lost Samples: 0
#
# Samples: 41K of event 'cycles'
# Event count (approx.): 42137343851
...
# Samples: 1K of event 'offcpu-time'
# Event count (approx.): 587990831640

As you can see it spent most of off-cpu time in read and write in
bench_sched_messaging(). The --call-graph=no was added just to make
the output concise here.
It uses perf hooks facility to control BPF program during the record
session rather than adding new BPF/off-cpu specific calls.

perf report: Do not extend sample type of bpf-output event
Currently evsel__new_idx() sets more sample_type bits when it finds a BPF-output event. But it should honor what's recorded in the perf data file rather than blindly sets the bits. Otherwise it could lead to a parse error when it recorded with a modified sample_type.

perf test: Add checking for perf stat CSV output.
Counts expected fields for various commands. No testing added for
summary mode since it is broken.
An example of the summary output is:
summary,263831,,instructions:u,1435072,100.0,0.46,insn per cycle
,,,,,1.37,stalled cycles per insn
This should be:
summary,263831,,instructions:u,1435072,100.0,0.46,insn per cycle
summary,,,,,,1.37,stalled cycles per insn
The output has 7 fields when it should have 8. Additionally, the newline
spacing is wrong, so it was excluded from testing until a fix is made.
Committer testing:
$ perf test "perf stat CSV output"
88: perf stat CSV output linter : Ok

perf stat: Add requires_cpu flag for uncore
Uncore events require a CPU i.e. it cannot be -1. The evsel system_wide flag is intended for events that should be on every CPU, which does not make sense for uncore events because uncore events do not map one-to-one with CPUs. These 2 requirements are not exactly the same, so introduce a new flag 'requires_cpu' for the uncore case.

perf build: Fix btf__load_from_kernel_by_id() feature check
The btf__load_from_kernel_by_id() only takes one arg, not two.
Committer notes:
I tested it just with an older libbpf, one where
btf__load_from_kernel_by_id() wasn't introduced yet.
A test with a newer dynamic libbpf would fail because the
btf__load_from_kernel_by_id() is there, but takes just one arg.
Fixes:

xfs: Changes for 5.19-rc1
This update includes:
- support for printk message indexing.
- large extent counts to provide support for up to 2^47 data extents and 2^32
attribute extents, allowing us to scale beyond 4 billion data extents
to billions of xattrs per inode.
- conversion of various flags fields to be consistently declared as
unsigned bit fields.
- improvements to realtime extent accounting and converts them to per-cpu
counters to match all the other block and inode accounting.
- reworks core log formatting code to reduce iterations, have a shorter, cleaner
fast path and generally be easier to understand and maintain.
- improvements to rmap btree searches that reduce overhead by up
to 30% resulting in xfs_scrub runtime reductions of 15%.
- improvements to reflink that remove the size limitations in remapping operations
and greatly reduce the size of transaction reservations.
- reworks the minimum log size calculations to allow us to change transaction
reservations without changing the minimum supported log size.
- removal of quota warning support as it has never been used on Linux.
- intent whiteouts to allow us to cancel intents that are completed entirely
in memory rather than having use CPU and disk bandwidth formatting and writing
them into the journal when it is not necessary. This makes rmap, reflink and
extent freeing slightly more efficient, but provides massive improvements
for....
- Logged Attribute Replay feature support. This is a fundamental change to the
way we modify attributes, laying the foundation for future integration of
attribute modifications as part of other atomic transactional operations the
filesystem performs.
- Lots of cleanups and fixes for the logged attribute replay functionality.

Merge tag 'xfs-5.19-for-linus' of git://git.kernel.org/pub/scm/fs/xfs/xfs-linux
Pull xfs updates from Dave Chinner:
"This is a big update with lots of new code. The summary below them
all, so I'll just touch on teh higlights. The two main new features
are Large Extent Counts and Logged Attribute Replay - these are two
new foundational features that we are building more complex future
features on top of.
For upcoming functionality, we need to be able to store hundreds of
millions of xattrs per inode. The Large Extent Count feature removes
the limits that prevent this scale of xattr storage, and while we were
modifying the on disk extent count format we also increased the number
of data extents we support per inode from 2^32 to 2^47.
We also need to be able to modify xattrs as part of larger atomic
transactions rather than as standalone transactions. The Logged
Attribute Replay feature introduces the infrastructure that allows us
to use intents to record the attribute modifications in the journal
before we start them, hence allowing other atomic transactions to log
attribute modification intents and then defer the actual modification
to later. If we then crash, log recovery then guarantees that the
attribute is replayed in the context of the atomic transaction that
logged the intent.
A significant chunk of the commits in this merge are for the base
attribute replay functionality along with fixes, improvements and
cleanups related to this new functioanlity. Allison deserves a big
round of thanks for her ongoing work to get this functionality into
XFS.
There are also many other smaller changes and improvements, so overall
this is one of the bigger XFS merge requests in some time.
I will be following up next week with another smaller pull request -
we already have another round of fixes and improvements to the logged
attribute replay functionality just about ready to go. They'll soak
and test over the next week, and I'll send a pull request for them
near the end of the merge window.
Summary:
- support for printk message indexing.
- large extent counts to provide support for up to 2^47 data extents
and 2^32 attribute extents, allowing us to scale beyond 4 billion
data extents to billions of xattrs per inode.

Not much dramatic changes at this time, but we've received quite
a lot of changes for ASoC, while there are still a few fixes and
quirks for usual HD- and USB-auido. Here are some highlights.
* ASoC:
- Overhaul of endianness specification for data formats, avoiding
needless restrictions due to CODECs
- Initial stages of Intel AVS driver merge
- Introduction of v4 IPC mechanism for SOF
- TDM mode support for AK4613
- Support for Analog Devices ADAU1361, Cirrus Logic CS35L45, Maxim
MAX98396, MediaTek MT8186, NXP i.MX8 micfil and SAI interfaces,
nVidia Tegra186 ASRC, and Texas Instruments TAS2764 and TAS2780
* Others
- A few regression fixes after the USB-audio endpoint management
refactoring
- More enhancements for Cirrus HD-audio codec support (still ongoing)
- Addition of generic serial MIDI driver

Add new functions to alloc check for 5.19-rc1
Hi Linus, Please, pull the following patch that adds new alloc functions to alloc with multiplies check. kvmalloc() and kvzalloc() functions have now 2-factor multiplication argument forms kvmalloc_array() and kvcalloc().

Networking changes for 5.19.
Core
----
- Support TCPv6 segmentation offload with super-segments larger than
64k bytes using the IPv6 Jumbogram extension header (AKA BIG TCP).
- Generalize skb freeing deferral to per-cpu lists, instead of
per-socket lists.
- Add a netdev statistic for packets dropped due to L2 address
mismatch (rx_otherhost_dropped).
- Continue work annotating skb drop reasons.
- Accept alternative netdev names (ALT_IFNAME) in more netlink
requests.
- Add VLAN support for AF_PACKET SOCK_RAW GSO.
- Allow receiving skb mark from the socket as a cmsg.
- Enable memcg accounting for veth queues, sysctl tables and IPv6.
BPF
---
- Add libbpf support for User Statically-Defined Tracing (USDTs).
- Speed up symbol resolution for kprobes multi-link attachments.
- Support storing typed pointers to referenced and unreferenced
objects in BPF maps.
- Add support for BPF link iterator.
- Introduce access to remote CPU map elements in BPF per-cpu map.
- Allow middle-of-the-road settings for the
kernel.unprivileged_bpf_disabled sysctl.
- Implement basic types of dynamic pointers e.g. to allow for
dynamically sized ringbuf reservations without extra memory copies.
Protocols
---------
- Retire port only listening_hash table, add a second bind table
hashed by port and address. Avoid linear list walk when binding
to very popular ports (e.g. 443).
- Add bridge FDB bulk flush filtering support allowing user space
to remove all FDB entries matching a condition.
- Introduce accept_unsolicited_na sysctl for IPv6 to implement
router-side changes for RFC9131.
- Support for MPTCP path manager in user space.
- Add MPTCP support for fallback to regular TCP for connections
that have never connected additional subflows or transmitted
out-of-sequence data (partial support for RFC8684 fallback).
- Avoid races in MPTCP-level window tracking, stabilize and improve
throughput.
- Support lockless operation of GRE tunnels with seq numbers enabled.
- WiFi support for host based BSS color collision detection.
- Add support for SO_TXTIME/SCM_TXTIME on CAN sockets.
- Support transmission w/o flow control in CAN ISOTP (ISO 15765-2).
- Support zero-copy Tx with TLS 1.2 crypto offload (sendfile).
- Allow matching on the number of VLAN tags via tc-flower.
- Add tracepoint for tcp_set_ca_state().
Driver API
----------
- Improve error reporting from classifier and action offload.
- Add support for listing line cards in switches (devlink).
- Add helpers for reporting page pool statistics with ethtool -S.
- Add support for reading clock cycles when using PTP virtual clocks,
instead of having the driver convert to time before reporting.
This makes it possible to report time from different vclocks.
- Support configuring low-latency Tx descriptor push via ethtool.
- Separate Clause 22 and Clause 45 MDIO accesses more explicitly.
