perf record: Support sample-read topdown metric group
With the hardware TopDown metrics feature, sample-read feature should be supported for a topdown group, e.g., sample a non-topdown event and read a topdown metric group. But the current perf record code errors out. For a topdown metric group, the slots event must be the leader of the group, but the leader slots event doesn't support sampling. To support sample-read the topdown metric group, use the 2nd event of the group as the "leader" for the purposes of sampling. Only the platform with Topdown metic feature supports sample-read the topdown group. Add arch_topdown_sample_read() to indicate whether the topdown group supports sample-read.

perf tools: Rename group to topdown
The group.h/c only include TopDown group related functions. The name "group" is too generic and inaccurate. Use the name "topdown" to replace it. Move topdown related functions to a dedicated file, topdown.c.

perf tools fixes for v5.9: 3rd batch
- Set PERF_SAMPLE_PERIOD if attr->freq is set.
- Remove trailing commas from AMD JSON vendor event files.
- Don't clear event's period if set by a event definition term.
- Leader sampling shouldn't clear sample period in 'perf test'.
- Fix the "signal" test inline assembly when built with DEBUG=1.
- Fix memory leaks detected by ASAN, some in normal paths, some in error
paths.
- Fix 2 memory sanitizer warnings in 'perf bench'.
- Fix the ratio comments of miss-events in 'perf stat'.
- Prevent override of attr->sample_period for libpfm4 events.
- Sync kvm.h and in.h headers with the kernel sources.

Test results:
The first ones are container based builds of tools/perf with and without libelf
support. Where clang is available, it is also used to build perf with/without
libelf, and building with LIBCLANGLLVM=1 (built-in clang) with gcc and clang
when clang and its devel libraries are installed.
The objtool and samples/bpf/ builds are disabled now that I'm switching from
using the sources in a local volume to fetching them from a http server to
build it inside the container, to make it easier to build in a container cluster.
Those will come back later.
Several are cross builds, the ones with -x-ARCH and the android one, and those
may not have all the features built, due to lack of multi-arch devel packages,
available and being used so far on just a few, like
debian:experimental-x-{arm64,mipsel}.
The 'perf test' one will perform a variety of tests exercising
tools/perf/util/, tools/lib/{bpf,traceevent,etc}, as well as run perf commands
with a variety of command line event specifications to then intercept the
sys_perf_event syscall to check that the perf_event_attr fields are set up as
expected, among a variety of other unit tests.
Then there is the 'make -C tools/perf build-test' ones, that build tools/perf/
with a variety of feature sets, exercising the build with an incomplete set of
features as well as with a complete one. It is planned to have it run on each
of the containers mentioned above, using some container orchestration
infrastructure. Get in contact if interested in helping having this in place.

perf stat: Fix the ratio comments of miss-events
'perf stat' displays miss ratio of L1-dcache, L1-icache, dTLB cache, iTLB cache and LL-cache. Take L1-dcache for example, miss ratio is caculated as "L1-dcache-load-misses/L1-dcache-loads". So "of all L1-dcache hits" is unsuitable to describe it, and "of all L1-dcache accesses" seems better. The comments of L1-icache, dTLB cache, iTLB cache and LL-cache are fixed in the same way.

perf metric: Do not free metric when failed to resolve
It's dangerous to free the original metric when it's called from
resolve_metric() as it's already in the metric_list and might have other
resources too. Instead, it'd better let them bail out and be released
properly at the later stage.
So add a check when it's called from metricgroup__add_metric() and
release it. Also make sure that mp is set properly.

perf record: Don't clear event's period if set by a term
If events in a group explicitly set a frequency or period with leader
sampling, don't disable the samples on those events.
Prior to 5.8:
perf record -e '{cycles/period=12345000/,instructions/period=6789000/}:S'
would clear the attributes then apply the config terms. In commit

perf record: Prevent override of attr->sample_period for libpfm4 events
Before: $ perf record -c 10000 --pfm-events=cycles:period=77777 Would yield a cycles event with period=10000, instead of 77777. the event string and perf record initializing the event. This was due to an ordering issue between libpfm4 parsing events with attr->sample_period != 0 by the time intent of the author. perf_evsel__config() is invoked.

It's caused by the symbol __test_function being in the ".bss" section:

I guess most of the time we're just lucky the inline asm ended up in the

fbcon: remove soft scrollback code
This (and the VGA soft scrollback) turns out to have various nasty small special cases that nobody really is willing to fight. The soft scrollback code was really useful a few decades ago when you typically used the console interactively as the main way to interact with the machine, but that just isn't the case any more. So it's not worth dragging along.

btrfs: fix wrong address when faulting in pages in the search ioctl
When faulting in the pages for the user supplied buffer for the search ioctl, we are passing only the base address of the buffer to the function fault_in_pages_writeable(). This means that after the first iteration of the while loop that searches for leaves, when we have a non-zero offset, stored in 'sk_offset', we try to fault in a wrong page range. So fix this by adding the offset in 'sk_offset' to the base address of the user supplied buffer when calling fault_in_pages_writeable(). Several users have reported that the applications compsize and bees have started to operate incorrectly since commit |
