It's a pseudo data type and has no field.

Like 'perf report', it can take a while to process samples.
Show a progress window to inform users how that it is not stuck.

Support data type profiling output on TUI.
Testing from Arnaldo:
First make sure that the debug information for your workload binaries
in embedded in them by building it with '-g' or install the debuginfo
packages, since our workload is 'find':
root@number:~# type find
find is hashed (/usr/bin/find)
root@number:~# rpm -qf /usr/bin/find
findutils-4.9.0-5.fc39.x86_64
root@number:~# dnf debuginfo-install findutils
<SNIP>
root@number:~#
Then collect some data:
root@number:~# echo 1 > /proc/sys/vm/drop_caches
root@number:~# perf mem record find / > /dev/null
[ perf record: Woken up 1 times to write data ]
[ perf record: Captured and wrote 0.331 MB perf.data (3982 samples) ]
root@number:~#
Finally do data-type annotation with the following command, that will
default, as 'perf report' to the --tui mode, with lines colored to
highlight the hotspots, etc.
root@number:~# perf annotate --data-type
Annotate type: 'struct predicate' (58 samples)

Like in stdio, it should print all events in a group together.
Committer notes:
Collect it:
root@number:~# perf record -a -e '{cpu_core/mem-loads,ldlat=30/P,cpu_core/mem-stores/P}'
^C[ perf record: Woken up 8 times to write data ]
[ perf record: Captured and wrote 4.980 MB perf.data (55825 samples) ]
root@number:~#
Then do it in stdio:
root@number:~# perf annotate --stdio --data-type
Annotate type: 'union ' in /usr/lib64/libc.so.6 (1131 samples):
event[0] = cpu_core/mem-loads,ldlat=30/P
event[1] = cpu_core/mem-stores/P
============================================================================
Percent offset size field
100.00 100.00 0 40 union {
100.00 100.00 0 40 struct __pthread_mutex_s __data {
48.61 23.46 0 4 int __lock;
0.00 0.48 4 4 unsigned int __count;
6.38 41.32 8 4 int __owner;
8.74 34.02 12 4 unsigned int __nusers;
35.66 0.26 16 4 int __kind;
0.61 0.45 20 2 short int __spins;
0.00 0.00 22 2 short int __elision;
0.00 0.00 24 16 __pthread_list_t __list {
0.00 0.00 24 8 struct __pthread_internal_list* __prev;
0.00 0.00 32 8 struct __pthread_internal_list* __next;
};
};
0.00 0.00 0 0 char* __size;
48.61 23.94 0 8 long int __align;
};
Now with TUI before this patch:
root@number:~# perf annotate --tui --data-type
Annotate type: 'union ' (790 samples)
Percent Offset Size Field
100.00 0 40 union {
100.00 0 40 struct __pthread_mutex_s __data {
48.61 0 4 int __lock;
0.00 4 4 unsigned int __count;
6.38 8 4 int __owner;
8.74 12 4 unsigned int __nusers;
35.66 16 4 int __kind;
0.61 20 2 short int __spins;
0.00 22 2 short int __elision;
0.00 24 16 __pthread_list_t __list {
0.00 24 8 struct __pthread_internal_list* __prev;
0.00 32 8 struct __pthread_internal_list* __next;
0.00 0 0 char* __size;
48.61 0 8 long int __align;
};
And now after this patch:
Annotate type: 'union ' (790 samples)
Percent Offset Size Field
100.00 100.00 0 40 union {
100.00 100.00 0 40 struct __pthread_mutex_s __data {
48.61 23.46 0 4 int __lock;
0.00 0.48 4 4 unsigned int __count;
6.38 41.32 8 4 int __owner;
8.74 34.02 12 4 unsigned int __nusers;
35.66 0.26 16 4 int __kind;
0.61 0.45 20 2 short int __spins;
0.00 0.00 22 2 short int __elision;
0.00 0.00 24 16 __pthread_list_t __list {
0.00 0.00 24 8 struct __pthread_internal_list* __prev;
0.00 0.00 32 8 struct __pthread_internal_list* __next;
};
};
0.00 0.00 0 0 char* __size;
48.61 23.94 0 8 long int __align;
};
On a followup patch the --tui output should have this that is present in
--stdio:
And the --stdio has all the missing info in TUI:
Annotate type: 'union ' in /usr/lib64/libc.so.6 (1131 samples):
event[0] = cpu_core/mem-loads,ldlat=30/P
event[1] = cpu_core/mem-stores/P

When the hist entry has the type info, it should be able to display the
annotation browser for the type like in `perf annotate --data-type`.

The data type profiling alone doesn't need the sample histogram for
functions. It only needs the histogram for the types.
Let's remove the condition in the report_callback to check if data type
profiling is selected and make sure the annotation has the 'struct
annotated_source' instantiated before calling symbol__disassemble().

Thanks, applied.
