- hid-multitouch devices should be put into high-latency mode when
suspended in order to be in line with Windows Precision Touchpad
guidelines. From Blaž Hrastnik.
- improved handling of generic HID keyboard (no more splitting system
and consumer controls away), in order to make it easier for userspace
to figure out the details of the device easier. From Dmitry Torokhov.
- report data sanitization fixes from Will McVicker and Randy Dunlap
The common cros-ec keymap has been defined as macros. This patch uses
the macros to simply linux,keymap in cros-ec-keyboard.dtsi file.
This patch also creates an alias for keyboard-controller to make it
easier to override the keymap in board-specific dts later.

In Chrome OS, the keyboard matrix can be split to two groups:
The keymap for the top row keys can be customized based on OEM
preference, while the keymap for the other keys is generic/fixed
across boards.
This patch creates marcos for the keymaps of these two groups, making
it easier to reuse the generic portion of keymap when we override the
keymap in the board-specific dts for custom top row design.

The top-row keys in a keyboard usually have dual functionalities.
E.g. A function key "F1" is also an action key "Browser back".
Therefore, when an application receives an action key code from
a top-row key press, the application needs to know how to correlate
the action key code with the function key code and do the conversion
whenever necessary.
Since the userpace already knows the key scanlines (row/column)
associated with a received key code. Essentially, the userspace only
needs a mapping between the key row/column and the matching physical
location in the top row.
So, enhance the cros-ec-keyb driver to create such a mapping
and expose it to userspace in the form of a function_row_physmap
attribute. The attribute would be a space separated ordered list of
row/column codes for the keys in the function row, in a left-to-right
order.
The attribute will only be present when the device has a custom design
for the top-row keys.

- Update to the way irqs and preemption is tracked via the trace event PC field
- Fix handling of unregistering event failing due to allocate memory.
This is only triggered by failure injection, as it is pretty much guaranteed
to have less than a page allocation succeed.
- Do not show the useless "filter" or "enable" files for the "ftrace" trace
system, as they have no effect on doing anything.
- Add a warning if kprobes are registered more than once.
- Synthetic events now have their fields parsed by semicolons.
Old formats without semicolons will still work, but new features will
require them.
- New option to allow trace events to show %p without hashing in trace file.
The trace file can only be read by root, and reading the raw event buffer
did not have any pointers hashed, so this does not expose anything new.
- New directory in tools called tools/tracing, where a new tool that reads
sequential latency reports from the ftrace latency tracers.
- Other minor fixes and cleanups.

- Support instruction latency in 'perf report', with both memory latency
(weight) and instruction latency information, users can locate expensive load
instructions and understand time spent in different stages.
- Extend 'perf c2c' to display the number of loads which were blocked by data
or address conflict.
- Add 'perf stat' support for L2 topdown events in systems such as Intel's
Sapphire rapids server.
- Add support for PERF_SAMPLE_CODE_PAGE_SIZE in various tools, as a sort key, for instance:
perf report --stdio --sort=comm,symbol,code_page_size
- New 'perf daemon' command to run long running sessions while providing a way to control
the enablement of events without restarting a traditional 'perf record' session.
- Enable counting events for BPF programs in 'perf stat' just like for other
targets (tid, cgroup, cpu, etc), e.g.:
# perf stat -e ref-cycles,cycles -b 254 -I 1000
1.487903822 115,200 ref-cycles
1.487903822 86,012 cycles
2.489147029 80,560 ref-cycles
2.489147029 73,784 cycles
^C#
The example above counts 'cycles' and 'ref-cycles' of BPF program of id 254.
It is similar to bpftool-prog-profile command, but more flexible.
- Support the new layout for PERF_RECORD_MMAP2 to carry the DSO build-id using infrastructure
generalised from the eBPF subsystem, removing the need for traversing the perf.data file
to collect build-ids at the end of 'perf record' sessions and helping with long running
sessions where binaries can get replaced in updates, leading to possible mis-resolution
of symbols.
- Support filtering by hex address in 'perf script'.
- Support DSO filter in 'perf script', like in other perf tools.
- Add namespaces support to 'perf inject'
- Add support for SDT (Dtrace Style Markers) events on ARM64.
perf record:
- Fix handling of eventfd() when draining a buffer in 'perf record'.
- Improvements to the generation of metadata events for pre-existing threads (mmaps, comm, etc),
speeding up the work done at the start of system wide or per CPU 'perf record' sessions.
Hardware tracing:
- Initial support for tracing KVM with Intel PT.
- Intel PT fixes for IPC
- Support Intel PT PSB (synchronization packets) events.
- Automatically group aux-output events to overcome --filter syntax.
- Enable PERF_SAMPLE_DATA_SRC on ARMs SPE.
- Update ARM's CoreSight hardware tracing OpenCSD library to v1.0.0.
perf annotate TUI:
- Fix handling of 'k' ("show line number") hotkey
- Fix jump parsing for C++ code.
perf probe:
- Add protection to avoid endless loop.
cgroups:
- Avoid reading cgroup mountpoint multiple times, caching it.
- Fix handling of cgroup v1/v2 in mixed hierarchy.
Symbol resolving:
- Add OCaml symbol demangling.
- Further fixes for handling PE executables when using perf with Wine and .exe/.dll files.
- Fix 'perf unwind' DSO handling.
- Resolve symbols against debug file first, to deal with artifacts related to LTO.
- Fix gap between kernel end and module start on powerpc.
Reporting tools:
- The DSO filter shouldn't show samples in unresolved maps.
- Improve debuginfod support in various tools.
build ids:
- Fix 16-byte build ids in 'perf buildid-cache', add a 'perf test' entry for that case.
perf test:
- Support for PERF_SAMPLE_WEIGHT_STRUCT.
- Add test case for PERF_SAMPLE_CODE_PAGE_SIZE.
- Shell based tests for 'perf daemon's commands ('start', 'stop, 'reconfig', 'list', etc).
- ARM cs-etm 'perf test' fixes.
- Add parse-metric memory bandwidth testcase.
Compiler related:
- Fix 'perf probe' kretprobe issue caused by gcc 11 bug when used with -fpatchable-function-entry.
- Fix ARM64 build with gcc 11's -Wformat-overflow.
- Fix unaligned access in sample parsing test.
- Fix printf conversion specifier for IP addresses on arm64, s390 and powerpc.
Arch specific:
- Support exposing Performance Monitor Counter SPRs as part of extended regs on powerpc.
- Add JSON 'perf stat' metrics for ARM64's imx8mp, imx8mq and imx8mn DDR, fix imx8mm ones.
- Fix common and uarch events for ARM64's A76 and Ampere eMag

In the log, revokes are stored as a revoke descriptor (struct
gfs2_log_descriptor), followed by zero or more additional revoke blocks
(struct gfs2_meta_header). On filesystems with a blocksize of 4k, the
revoke descriptor contains up to 503 revokes, and the metadata blocks
contain up to 509 revokes each. We've so far been reserving space for
revokes in transactions in block granularity, so a lot more space than
necessary was being allocated and then released again.
This patch switches to assigning revokes to transactions individually
instead. Initially, space for the revoke descriptor is reserved and
handed out to transactions. When more revokes than that are reserved,
additional revoke blocks are added. When the log is flushed, the space
for the additional revoke blocks is released, but we keep the space for
the revoke descriptor block allocated.
Transactions may still reserve more revokes than they will actually need
in the end, but now we won't overshoot the target as much, and by only
returning the space for excess revokes at log flush time, we further
reduce the amount of contention between processes.
Signed-off-by: Andreas Gruenbacher <agruenba@redhat.com>
The current log space allocation logic is hard to understand or extend.
The principle it that when the log is flushed, we may or may not have a
transaction active that has space allocated in the log. To deal with
that, we set aside a magical number of blocks to be used in case we
don't have an active transaction. It isn't clear that the pool will
always be big enough. In addition, we can't return unused log space at
the end of a transaction, so the number of blocks allocated must exactly
match the number of blocks used.
Simplify this as follows:
* When transactions are allocated or merged, always reserve enough
blocks to flush the transaction (err on the safe side).
* In gfs2_log_flush, return any allocated blocks that haven't been used.
* Maintain a pool of spare blocks big enough to do one log flush, as
before.
* In gfs2_log_flush, when we have no active transaction, allocate a
suitable number of blocks. For that, use the spare pool when
called from logd, and leave the pool alone otherwise. This means
that when the log is almost full, logd will still be able to do one
more log flush, which will result in more log space becoming
available.
This will make the log space allocator code easier to work with in
the future.

Another fairly small set of changes of changes this cycle. The most
significant functional change is a fix to better manage the flags
when allocating memory.
Additionally there is the removal of some unused code (which is
slightly more dramatic than it sounds given it means there are now no
tasklets in kgdb) together with a tidy up of the debug prints and some
spelling corrections for the documentation.

Merge tag 'docs-5.12' of git://git.lwn.net/linux
Pull documentation updates from Jonathan Corbet:
"It has been a relatively quiet cycle in docsland.
- As promised, the minimum Sphinx version to build the docs is now
1.7, and we have dropped support for Python 2 entirely. That
allowed the removal of a bunch of compatibility code.
- A set of treewide warning fixups from Mauro that I applied after it
became clear nobody else was going to deal with them.
- The automarkup mechanism can now create cross-references from
relative paths to RST files.
- More translations, typo fixes, and warning fixes"
