testing: net-drv: use stats64 for testing
Testing a network device that has large numbers of bytes/packets may
overflow. Using stats64 when comparing fixes this problem.
I tripped on this while iterating on a qstats patch for mlx5. See below
for confirmation without my added code that this is a bug.
Before this patch (with added debugging output):
$ NETIF=eth0 tools/testing/selftests/drivers/net/stats.py
KTAP version 1
1..4
ok 1 stats.check_pause
ok 2 stats.check_fec
rstat: 481708634 qstat: 666201639514 key: tx-bytes
not ok 3 stats.pkt_byte_sum
ok 4 stats.qstat_by_ifindex
Note the huge delta above ^^^ in the rtnl vs qstats.
After this patch:
$ NETIF=eth0 tools/testing/selftests/drivers/net/stats.py
KTAP version 1
1..4
ok 1 stats.check_pause
ok 2 stats.check_fec
ok 3 stats.pkt_byte_sum
ok 4 stats.qstat_by_ifindex
It looks like rtnl_fill_stats in net/core/rtnetlink.c will attempt to
copy the 64bit stats into a 32bit structure which is probably why this
behavior is occurring.
To show this is happening, you can get the underlying stats that the
stats.py test uses like this:
$ ./cli.py --spec ../../../Documentation/netlink/specs/rt_link.yaml \
--do getlink --json '{"ifi-index": 7}'
And examine the output (heavily snipped to show relevant fields):
'stats': {
'multicast': 3739197,
'rx-bytes': 1201525399,
'rx-packets': 56807158,
'tx-bytes': 492404458,
'tx-packets': 1200285371,
'stats64': {
'multicast': 3739197,
'rx-bytes': 35561263767,
'rx-packets': 56807158,
'tx-bytes': 666212335338,
'tx-packets': 1200285371,
The stats.py test prior to this patch was using the 'stats' structure
above, which matches the failure output on my system.
Comparing side by side, rx-bytes and tx-bytes, and getting ethtool -S
output:
rx-bytes stats: 1201525399
rx-bytes stats64: 35561263767
rx-bytes ethtool: 36203402638
tx-bytes stats: 492404458
tx-bytes stats64: 666212335338
tx-bytes ethtool: 666215360113
Note that the above was taken from a system with an mlx5 NIC, which only
exposes ndo_get_stats64.
Based on the ethtool output and qstat output, it appears that stats.py
should be updated to use the 'stats64' structure for accurate
comparisons when packet/byte counters get very large.
To confirm that this was not related to the qstats code I was iterating
on, I booted a kernel without my driver changes and re-ran the test
which shows the qstats are skipped (as they don't exist for mlx5):
NETIF=eth0 tools/testing/selftests/drivers/net/stats.py
KTAP version 1
1..4
ok 1 stats.check_pause
ok 2 stats.check_fec
ok 3 stats.pkt_byte_sum # SKIP qstats not supported by the device
ok 4 stats.qstat_by_ifindex # SKIP No ifindex supports qstats
But, fetching the stats using the CLI
$ ./cli.py --spec ../../../Documentation/netlink/specs/rt_link.yaml \
--do getlink --json '{"ifi-index": 7}'
Shows the same issue (heavily snipped for relevant fields only):
'stats': {
'multicast': 105489,
'rx-bytes': 530879526,
'rx-packets': 751415,
'tx-bytes': 2510191396,
'tx-packets': 27700323,
'stats64': {
'multicast': 105489,
'rx-bytes': 530879526,
'rx-packets': 751415,
'tx-bytes': 15395093284,
'tx-packets': 27700323,
Comparing side by side with ethtool -S on the unmodified mlx5 driver:
tx-bytes stats: 2510191396
tx-bytes stats64: 15395093284
tx-bytes ethtool: 17718435810

- A series ("kbuild: enable more warnings by default") from Arnd
Bergmann which enables a number of additional build-time warnings. We
fixed all the fallout which we could find, there may still be a few
stragglers.
- Samuel Holland has developed the series "Unified cross-architecture
kernel-mode FPU API". This does a lot of consolidation of
per-architecture kernel-mode FPU usage and enables the use of newer AMD
GPUs on RISC-V.

perf tools fixes and improvements for v6.10:
- 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->b->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.
- 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.
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'.

Merge tag 'perf-tools-for-v6.10-1-2024-05-21' of git://git.kernel.org/pub/scm/linux/kernel/git/perf/perf-tools
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->b->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

selftest: af_unix: Make SCM_RIGHTS into OOB data.
scm_rights.c covers various test cases for inflight file descriptors and garbage collector for AF_UNIX sockets. Currently, SCM_RIGHTS messages are sent with 3-bytes string, and it's not good for MSG_OOB cases, as SCM_RIGTS cmsg goes with the first 2-bytes, which is non-OOB data. Let's send SCM_RIGHTS messages with 1-byte character to pack SCM_RIGHTS into OOB data.

selftests/net: use tc rule to filter the na packet
Test arp_ndisc_untracked_subnets use tcpdump to filter the unsolicited
and untracked na messages. It set -e before calling tcpdump. But if
tcpdump filters 0 packet, it will return none zero, and cause the script
to exit.
Instead of using slow tcpdump to capture packets, let's using tc rule
to filter out the na message.
At the same time, fix function setup_v6 which only needs one parameter.
Move all the related helpers from forwarding lib.sh to net lib.sh.

asm-generic cleanups for 6.10
These are a few cross-architecture cleanup patches:
- Thomas Zimmermann works on separating fbdev support from the asm/video.h
contents that may be used by either the old fbdev drivers or the
newer drm display code.
- Thorsten Blum contributes cleanups for the generic bitops code
and asm-generic/bug.h
- I remove the orphaned include/asm-generic/page.h header that used to

Android was seeing a compilation error because its C library does not
define LINE_MAX. Since LINE_MAX is only used to determine the size of
test_name[] and 1024 should be enough for the test name, use 1024 instead
of LINE_MAX.

The usual shower of singleton fixes and minor series all over MM,
documented (hopefully adequately) in the respective changelogs. Notable
series include:
- Lucas Stach has provided some page-mapping
cleanup/consolidation/maintainability work in the series "mm/treewide:
Remove pXd_huge() API".
- In the series "Allow migrate on protnone reference with
MPOL_PREFERRED_MANY policy", Donet Tom has optimized mempolicy's
MPOL_PREFERRED_MANY mode, yielding almost doubled performance in one
test.
- In their series "Memory allocation profiling" Kent Overstreet and
Suren Baghdasaryan have contributed a means of determining (via
/proc/allocinfo) whereabouts in the kernel memory is being allocated:
number of calls and amount of memory.
- Matthew Wilcox has provided the series "Various significant MM
patches" which does a number of rather unrelated things, but in largely
similar code sites.
- In his series "mm: page_alloc: freelist migratetype hygiene" Johannes
Weiner has fixed the page allocator's handling of migratetype requests,
with resulting improvements in compaction efficiency.
- In the series "make the hugetlb migration strategy consistent" Baolin
Wang has fixed a hugetlb migration issue, which should improve hugetlb
allocation reliability.
- Liu Shixin has hit an I/O meltdown caused by readahead in a
memory-tight memcg. Addressed in the series "Fix I/O high when memory
almost met memcg limit".
- In the series "mm/filemap: optimize folio adding and splitting" Kairui
Song has optimized pagecache insertion, yielding ~10% performance
improvement in one test.
- Baoquan He has cleaned up and consolidated the early zone
initialization code in the series "mm/mm_init.c: refactor
free_area_init_core()".

Pull mm updates from Andrew Morton:
"The usual shower of singleton fixes and minor series all over MM,
documented (hopefully adequately) in the respective changelogs.
Notable series include:
- Lucas Stach has provided some page-mapping cleanup/consolidation/
maintainability work in the series "mm/treewide: Remove pXd_huge()
API".
- In the series "Allow migrate on protnone reference with
MPOL_PREFERRED_MANY policy", Donet Tom has optimized mempolicy's
MPOL_PREFERRED_MANY mode, yielding almost doubled performance in

Suren Baghdasaryan have contributed a means of determining (via
/proc/allocinfo) whereabouts in the kernel memory is being
allocated: number of calls and amount of memory.
- Matthew Wilcox has provided the series "Various significant MM
patches" which does a number of rather unrelated things, but in
largely similar code sites.
- In his series "mm: page_alloc: freelist migratetype hygiene"
Johannes Weiner has fixed the page allocator's handling of
migratetype requests, with resulting improvements in compaction
efficiency.
- In the series "make the hugetlb migration strategy consistent"
Baolin Wang has fixed a hugetlb migration issue, which should
improve hugetlb allocation reliability.
- Liu Shixin has hit an I/O meltdown caused by readahead in a
memory-tight memcg. Addressed in the series "Fix I/O high when
memory almost met memcg limit".
- In the series "mm/filemap: optimize folio adding and splitting"
Kairui Song has optimized pagecache insertion, yielding ~10%
performance improvement in one test.

Specific for timerlat:
- Improves the output of timerlat top by adding a missing \n,
and by avoiding printing color-formatting characters where
they are translated to regular characters.
- Improves timerlat auto-analysis output by replacing '\t'
with spaces to avoid copy-and-paste issues when reporting
problems.
- For timerlat, make the user-space (-u) option the default,
as it is the most complete test. Add a -k option to use
the in-kernel workload.
- On timerlat top and hist, add a summary with the overall
results. For instance, the minimum value for all CPUs,
the overall average and the maximum value from all CPUs.
- timerlat hist was printing initial values (i.e., 0 as max,
and ~0 as min) if the trace stopped before the first Ret-User
event. This problem was fixed by printing the " - "
no value string to the output if that was the case.
For all RTLA tools:
- Add a --warm-up <seconds> option, allowing the workload to
run for <seconds> before starting to collect results.
- Add a --trace-buffer-size option, allowing the user to set
the tracing buffer size for -t option. This option is mainly
useful for reducing the trace file. Now rtla depends on
libtracefs >= 1.6.
- Fix the -t [trace_file] parsing, now it does not require
the '=' before the option parameter, and better handles the
multiple ways a user can pass the trace_file.txt

user-event updates for v6.10:
- Minor update to the user_events interface The ABI of creating a user event states that the fields are separated by semicolons, and spaces should be ignored. But the parsing expected at least one space to be there (which was incorrect). Fix the reading of the string to handle fields separated by semicolons but no space between them. This does extend the API sightly as now "field;field" will now be parsed and not cause an error. But it should not cause any regressions as no logic should expect it to fail. Note, that the logic that parses the event fields to create the trace_event works with no spaces after the semi-colon. It is the logic that tests against existing events that is inconsistent. This causes registering an event without using spaces to succeed if it doesn't exist, but makes the same call that tries to register to the same event, but doesn't use spaces, fail. -----BEGIN PGP SIGNATURE----- iIoEABYIADIWIQRRSw7ePDh/lE+zeZMp5XQQmuv6qgUCZkZN1hQccm9zdGVkdEBn b29kbWlzLm9yZwAKCRAp5XQQmuv6qvCXAQDO8b2GeCuAMa2SW7PMFdpB2Tc2F5v4 WPBEKaLb0TU+7AEAwR0rCm22p9rpke754lcpZDz7xJNcyiyMkyXeJWCauQA= =PYwP -----END PGP SIGNATURE----- Merge tag 'trace-user-events-v6.10' of git://git.kernel.org/pub/scm/linux/kernel/git/trace/linux-trace Pull tracing user-event updates from Steven Rostedt: - Minor update to the user_events interface The ABI of creating a user event states that the fields are separated by semicolons, and spaces should be ignored.

tracing ring buffer updates for v6.10:
- Add ring_buffer memory mappings The tracing ring buffer was created based on being mostly used with the splice system call. It is broken up into page ordered sub-buffers and the reader swaps a new sub-buffer with an existing sub-buffer that's part of the write buffer. It then has total access to the swapped out sub-buffer and can do copyless movements of the memory into other mediums (file system, network, etc). The buffer is great for passing around the ring buffer contents in the kernel, but is not so good for when the consumer is the user space task itself. A new interface is added that allows user space to memory map the ring buffer. It will get all the write sub-buffers as well as reader sub-buffer (that is not written to). It can send an ioctl to change which sub-buffer is the new reader sub-buffer. The ring buffer is read only to user space. It only needs to call the ioctl when it is finished with a sub-buffer and needs a new sub-buffer that the writer will not write over. A self test program was also created for testing and can be used as an example for the interface to user space. The libtracefs (external to the kernel) also has code that interacts with this, although it is disabled until the interface is in a official release. It can be enabled by compiling the library with a special flag. This was used for testing applications that perform better with the buffer being mapped. Memory mapped buffers have limitations. The main one is that it can not be used with the snapshot logic. If the buffer is mapped, snapshots will be disabled. If any logic is set to trigger snapshots on a buffer, that buffer will not be allowed to be mapped. -----BEGIN PGP SIGNATURE----- iIoEABYIADIWIQRRSw7ePDh/lE+zeZMp5XQQmuv6qgUCZkYzDRQccm9zdGVkdEBn b29kbWlzLm9yZwAKCRAp5XQQmuv6qttNAQCj3I0OpeI1vms85ShIa7Eha2qes5uC Yml2fnapkmRSwAEAp5UTGxtDctycWOk9B9PA7/oJmLgATaQwRKoEeTUwfAA= =TyEB -----END PGP SIGNATURE----- Merge tag 'trace-ringbuffer-v6.10' of git://git.kernel.org/pub/scm/linux/kernel/git/trace/linux-trace Pull tracing ring buffer updates from Steven Rostedt: "Add ring_buffer memory mappings.

The buffer is great for passing around the ring buffer contents in the kernel, but is not so good for when the consumer is the user space task itself. A new interface is added that allows user space to memory map the ring buffer. It will get all the write sub-buffers as well as reader sub-buffer (that is not written to). It can send an ioctl to change which sub-buffer is the new reader sub-buffer. The ring buffer is read only to user space. It only needs to call the ioctl when it is finished with a sub-buffer and needs a new sub-buffer that the writer will not write over. A self test program was also created for testing and can be used as an example for the interface to user space. The libtracefs (external to the kernel) also has code that interacts with this, although it is disabled until the interface is in a official release. It can be enabled by compiling the library with a special flag. This was used for testing applications that perform better with the buffer being mapped. Memory mapped buffers have limitations. The main one is that it can not be used with the snapshot logic. If the buffer is mapped, snapshots will be disabled. If any logic is set to trigger snapshots on a buffer, that buffer will not be allowed to be mapped" * tag 'trace-ringbuffer-v6.10' of git://git.kernel.org/pub/scm/linux/kernel/git/trace/linux-trace: ring-buffer: Add cast to unsigned long addr passed to virt_to_page() ring-buffer: Have mmapped ring buffer keep track of missed events ring-buffer/selftest: Add ring-buffer mapping test Documentation: tracing: Add ring-buffer mapping tracing: Allow user-space mapping of the ring-buffer ring-buffer: Introducing ring-buffer mapping functions ring-buffer: Allocate sub-buffers with __GFP_COMP |

Probes updates for v6.10:
- tracing/probes: Adding new pseudo-types %pd and %pD support for dumping
dentry name from 'struct dentry *' and file name from 'struct file *'.
- uprobes: Some performance optimizations have been done.
. Speed up the BPF uprobe event by delaying the fetching of the uprobe
event arguments that are not used in BPF.
. Avoid locking by speculatively checking whether uprobe event is valid.
. Reduce lock contention by using read/write_lock instead of spinlock for
uprobe list operation. This improved BPF uprobe benchmark result 43% on
average.
- rethook: Removes non-fatal warning messages when tracing stack from BPF
and skip rcu_is_watching() validation in rethook if possible.
- objpool: Optimizing objpool (which is used by kretprobes and fprobe as
rethook backend storage) by inlining functions and avoid caching nr_cpu_ids
because it is a const value.
- fprobe: Add entry/exit callbacks types (code cleanup)
- kprobes: Check ftrace was killed in kprobes if it uses ftrace.

Vladimir said when adding this test:
The bridge driver fares particularly badly [...] mainly because
it does not implement IFF_UNICAST_FLT.

rtla: Fix -t\--trace[=file]
The -t option has an optional argument.
The usual case is for a short option to be specified without an '='
and for the long version to be specified with an '='
Various forms of this do not work as expected.
For example:
rtla timerlat hist -T50 -tfile.txt
will result in a truncated file name of "ile.txt"
Another example is that the long form without the '=' will result in the
default file name instead of the requested file name.
This patch properly parses the optional argument with and without '='
and with and without spaces for the short form.
This patch was also tested using -t and --trace without providing a file
name both as the last requested option and with a following long and
short option.
For example:
rtla timerlat hist -T50 -t -u
rtla timerlat hist -T50 --trace -u
This fix is applied to both timerlat top and hist
and to osnoise top and hist.
Here is the full testing for rtla timerlat hist.
Before applying the patch
rtla timerlat hist -T50 -t=file.txt
Works as expected, "file.txt"
rtla timerlat hist -T50 -tfile.txt
Truncated file name "ile.txt"
rtla timerlat hist -T50 -t file.txt
Default file name instead of file.txt
rtla timerlat hist -T50 --trace=file.txt
Truncated file name "ile.txt"
rtla timerlat hist -T50 --trace file.txt
Default file name "timerlat_trace.txt" instead of "file.txt"
After applying the patch:
rtla timerlat hist -T50 -t=file.txt
Works as expected, "file.txt"
rtla timerlat hist -T50 -tfile.txt
Works as expected, "file.txt"
rtla timerlat hist -T50 -t file.txt
Works as expected, "file.txt"
rtla timerlat hist -T50 --trace=file.txt
Works as expected, "file.txt"
rtla timerlat hist -T50 --trace file.txt
Works as expected, "file.txt"
In addition the following tests were performed to make sure that
the default file name worked as expected including with trailing
options.
rtla timerlat hist -T50 -t
Works as expected "timerlat_trace.txt"
rtla timerlat hist -T50 --trace
Works as expected "timerlat_trace.txt"
rtla timerlat hist -T50 -t -u
Works as expected "timerlat_trace.txt"
rtla timerlat hist -T50 --trace -u
Works as expected "timerlat_trace.txt"

rtla/timerlat: Fix histogram report when a cpu count is 0
On short runs it is possible to get no samples on a cpu, like this:
# rtla timerlat hist -u -T50
Index IRQ-001 Thr-001 Usr-001 IRQ-002 Thr-002 Usr-002
2 1 0 0 0 0 0
33 0 1 0 0 0 0
36 0 0 1 0 0 0
49 0 0 0 1 0 0
52 0 0 0 0 1 0
over: 0 0 0 0 0 0
count: 1 1 1 1 1 0
min: 2 33 36 49 52 18446744073709551615
avg: 2 33 36 49 52 -
max: 2 33 36 49 52 0
rtla timerlat hit stop tracing
IRQ handler delay: (exit from idle) 48.21 us (91.09 %)
IRQ latency: 49.11 us
Timerlat IRQ duration: 2.17 us (4.09 %)
Blocking thread: 1.01 us (1.90 %)
swapper/2:0 1.01 us
------------------------------------------------------------------------
Thread latency: 52.93 us (100%)
Max timerlat IRQ latency from idle: 49.11 us in cpu 2
Note, the value 18446744073709551615 is the same as ~0.
Fix this by reporting no results for the min, avg and max if the count
is 0.

rtla: Add --trace-buffer-size option
Add the option allow the users to set a different buffer size for the trace. For example, in large systems, the user might be interested on reducing the trace buffer to avoid large tracing files. The buffer size is specified in kB, and it is only affecting the tracing instance. The function trace_set_buffer_size() appears on libtracefs v1.6, so increase the minimum required version on Makefile.config.

tools/power turbostat: Avoid possible memory corruption due to sparse topology IDs
Save the highest core and package id when parsing topology to allocate enough memory when get_rapl_counters() is called with a core or a package id as a domain. Note that RAPL domains are per-package on Intel, but per-core on AMD. Thus, the RAPL code effectively runs in different modes on those two product lines.

tools/power turbostat: Add columns for clustered uncore frequency
New machines have multiple uncore frequencies per package, visible in /sys/devices/system/cpu/intel_uncore_frequency/uncore##/ turbostat now samples these frequencies each measurement interval. For each package, turbostat now prints "UMHzX.Y" columns, where X = domain_id, and Y = fabric_cluster_id. The system summary for each UMHzX.Y column is the average value for across all of the packages in the system. Signed-off-by: Len Brown <len.brown@intel.com> |

cgroup: Changes for v6.10
- The locking around cpuset hotplug processing has always been a bit of mess
which was worked around by making hotplug processing asynchronous. The
asynchronity isn't great and led to other issues. We tried to make the
behavior synchronous a while ago but that led to lockdep splats. Waiman
took another stab at cleaning up and making it synchronous. The patch has
been in -next for well over a month and there haven't been any complaints,
so fingers crossed.
- Tracepoints added to help understanding rstat lock contentions.
- A bunch of minor changes - doc updates, code cleanups and selftests.
