The 'type' sort key is to aggregate hist entries by data type they
access. Add mem_type field to hist_entry struct to save the type. If
hist_entry__get_data_type() returns NULL, it'd use the 'unknown_type'
instance.

It's the function to find out the type info from the given sample data
and will be called from the hist_entry sort logic when 'type' sort key
is used.
It first calls objdump to disassemble the instructions and figure out
information about memory access at the location. Maybe we can do it
better by analyzing the instruction directly, but I'll leave it for
later work.
The memory access is determined by checking instruction operands to
have "(" and then extract register name and offset. It'll return NULL
if no data type is found.

The annotate_get_insn_location() is to get the detailed information of
instruction locations like registers and offset. It has source and
target operands locations in an array. Each operand can have a register
and an offset. The offset is meaningful when mem_ref flag is set.

The evsel__get_arch() is to get architecture info from the environment.
It'll be used by other places later so let's factor it out.
Also add arch__is() to check the arch info by name.
Committer notes:
"get" is usually associated with refcounting, so we better rename this
at some point to a better name.

To aggregate accesses to the same data type, add 'data_types' tree in
DSO to maintain data types and find it by name and size.
It might have different data types that happen to have the same name,
so it also compares the size of the type.
Even if it doesn't 100% guarantee, it reduces the possibility of
mis-handling of such conflicts.
And I don't think it's common to have different types with the same
name.
Committer notes:
Very few cases on the Linux kernel, but there are some different types
with the same name, unsure if there is a debug mode in libbpf dedup that
warns about such cases, but there are provisions in pahole for that,
see:
"emit: Notice type shadowing, i.e. multiple types with the same name (enum, struct, union, etc)"

The find_data_type() is to get a data type from the memory access at the
given address (IP) using a register and an offset.
It requires DWARF debug info in the DSO and searches the list of
variables and function parameters in the scope.
In a pseudo code, it does basically the following:
find_data_type(dso, ip, reg, offset)
{
pc = map__rip_2objdump(ip);
CU = dwarf_addrdie(dso->dwarf, pc);
scopes = die_get_scopes(CU, pc);
for_each_scope(S, scopes) {
V = die_find_variable_by_reg(S, pc, reg);
if (V && V.type == pointer_type) {
T = die_get_real_type(V);
if (offset < T.size)
return T;
}
}
return NULL;
}
Committer notes:
The 'size' variable in check_variable() is 64-bit, so use PRIu64 and
inttypes.h to debug it.
Ditto at find_data_type_die().

The get_dwarf_regnum() returns a DWARF register number from a register
name string according to the psABI. Also add two pseudo encodings of
DWARF_REG_PC which is a register that are used by PC-relative addressing
and DWARF_REG_FB which is a frame base register. They need to be
handled in a special way.

The die_get_typename_from_type() is to get the name of the given DIE in
C-style type name.
The difference from die_get_typename() is that it does not retrieve the
DW_AT_type and use the given DIE directly. This will be used when users
know the type DIE already.

Maps are sometimes made overlapping, in particular kernel maps. If the
end of a map overlaps the start of the next, shorten the overlapping
map. This should remove potential non-determinism in maps__find, ie

Some dumping call backs need to be passed a FILE*. Expose debug file
via an accessor API for a consistent way to do this. Catch the
unlikely failure of it not being set. Switch two cases where stderr
was being used instead of debug_file.

Removing maps wasn't being done under the write lock. Similar to
maps__for_each_map(), iterate the entries but in this case remove the
entry based on the result of the callback. If an entry was removed
then maps_by_name() also needs updating, so add missed flush.
In dso__load_kcore(), the test of map to save would always be false with
REFCNT_CHECKING because of a missing RC_CHK_ACCESS/RC_CHK_EQUAL.

For exectable ELF file, which e_type is ET_EXEC, dso start address is a
absolute address other than offset. Just set vm_start to zero when dso
start is 0x400000, which means it is a exectable file.

Archives generated by the command 'perf archive' have to be unpacked
manually.
Following the addition of option '--all' now there also exist a nested
structure of tars, and after further discussion with Red Hat Global
Support Services, they found a feature correctly unpacking archives of
'perf archive' convenient.
Option '--unpack' of 'perf archive' unpacks archives generated by the
command 'perf archive' as well as archives generated when used with
option '--all'.
The 'perf.data' file is placed in the current directory, while debug
symbols are unpacked in '~/.debug' directory. A tar filename can be
passed as an argument, and if not provided the command tries to find a
viable perf.tar file for unpacking.

'perf archive' has limited functionality and people from Red Hat Global
Support Services sent a request for a new feature that would pack
perf.data file together with an archive with debug symbols created by
the command 'perf archive' as customers were being confused and often
would forget to send perf.data file with the debug symbols.
With this patch 'perf archive' now accepts an option '--all' that
generates archive 'perf.all-hostname-date-time.tar.bz2' that holds file
'perf.data' and a sub-tar 'perf.symbols.tar.bz2' with debug symbols. The
functionality of the command 'perf archive' was not changed.
Committer testing:
Run 'perf record' on a Intel 14900K machine, hybrid:
root@number:~# perf record -a sleep 5s
[ perf record: Woken up 1 times to write data ]
[ perf record: Captured and wrote 4.006 MB perf.data (15427 samples) ]
root@number:~# perf archive --all
Now please run:
$ tar xvf perf.all-number-20231219-104854.tar.bz2 && tar xvf perf.symbols.tar.bz2 -C ~/.debug
wherever you need to run 'perf report' on.

The macro maps__for_each_entry is error prone as it doesn't require
holding the maps lock.
Add a new function that iterates the maps holding the read lock.
Convert maps__find_symbol_by_name() and maps__fprintf() to use callbacks,
the latter being an example of where the read lock wasn't being held.

perf_cpu_map__nr()'s behavior around an empty CPU map is strange as it
returns that there is 1 CPU. Changing code that may rely on this
behavior is hard, we can at least document the behavior.

PMU name
When turning an event with attributes to the format including the PMU we
need to move the "event:attributes" format to "event/attributes/" so
that we can copy the event displayed and use it in the command line,
i.e. in 'perf top' we had:
1K cpu_atom/cycles:P/
11K cpu_core/cycles:P/
If I try to use that on the command line:
# perf top -e cpu_atom/cycles:P/
event syntax error: 'cpu_atom/cycles:P/'
\___ Bad event or PMU
Unable to find PMU or event on a PMU of 'cpu_atom'
Initial error:
event syntax error: 'cpu_atom/cycles:P/'
\___ unknown term 'cycles:P' for pmu
'cpu_atom'
valid terms:
event,pc,edge,offcore_rsp,ldlat,inv,umask,cmask,config,config1,config2,config3,name,period,freq,branch_type,time,call-graph,stack-size,no-inherit,inherit,max-stack,nr,no-overwrite,overwrite ,driver-config,percore,aux-output,aux-sample-size,metric-id,raw,legacy-cache,hardware

Usage: perf top [<options>]

lockdep reports.
