It always passes a whitespace to the function, thus we can just add it to the function body. Furthermore, it's only used in the normal output mode. Well, actually CSV used it but it doesn't need to since we don't care about the indentation or alignment in the CSV output. Signed-off-by:

We don't care about the alignment in the CSV output as it's intended for machine processing. Let's get rid of it to make the output more compact.

It caused some troubles when a lock inside kmalloc is contended because task local storage would allocate memory using kmalloc. It'd create a recusion and even crash in my system. There could be a couple of workarounds but I think the simplest one is to use a pre-allocated hash map. We could fix the task local storage to use the safe BPF allocator, but it takes time so let's change this until it happens actually. Signed-off-by:

augmented_raw_syscalls.c defines the bpf map 'syscalls' which is initialized by perf tool in user space to indicate which system calls are enabled for tracing, on the other flip eBPF program relies on the map to filter out the trace events which are not enabled. The map also includes a field 'string_args_len[6]' which presents the string length if the corresponding argument is a string type. Now the map 'syscalls' is not used, bpf program doesn't use it as filter anymore, this is replaced by using the function bpf_tail_call() and PROG_ARRAY syscalls map. And we don't need to explicitly set the string length anymore, bpf_probe_read_str() is smart to copy the string and return string length. Therefore, it's safe to remove the bpf map 'syscalls'. To consolidate the code, this patch removes the definition of map 'syscalls' from augmented_raw_syscalls.c and drops code for using the map in the perf trace. Note, since function trace__set_ev_qualifier_bpf_filter() is removed, calling trace__init_syscall_bpf_progs() from it is also removed. We don't need to worry it because trace__init_syscall_bpf_progs() is still invoked from trace__init_syscalls_bpf_prog_array_maps() for initialization the system call's bpf program callback.

On Arm64 a case is perf tools fails to find the corresponding trace point folder for system calls listed in the table 'syscalltbl_arm64', e.g. the generated system call table contains "lookup_dcookie" but we cannot find out the matched trace point folder for it. We need to figure out if there have any issue for the generated system call table, on the other hand, we need to handle the case when trace point folder is missed under sysfs, this patch sets the flag syscall::nonexistent as true and returns the error from trace__read_syscall_info(). Another problem is for trace__syscall_info(), it returns two different values if a system call doesn't exist: at the first time calling trace__syscall_info() it returns NULL when the system call doesn't exist, later if call trace__syscall_info() again for the same missed system call, it returns pointer of syscall. trace__syscall_info() checks the condition 'syscalls.table[id].name == NULL', but the name will be assigned in the first invoking even the system call is not found. So checking system call's name in trace__syscall_info() is not the right thing to do, this patch simply checks flag syscall::nonexistent to make decision if a system call exists or not, finally trace__syscall_info() returns the consistent result (NULL) if a system call doesn't existed.

When a system call is not detected, the reason is either because the system call ID is out of scope or failure to find the corresponding path in the sysfs, trace__read_syscall_info() returns zero. Finally, without returning an error value it introduces confusion for the caller. This patch lets the function trace__read_syscall_info() to return -EEXIST when a system call doesn't exist.

Rather than controlling the list output with passed flags, add callbacks that are called when an event or metric are encountered. State is passed to the callback so that command line options can be respected, alternatively the callbacks can be changed. Fix a few bugs: - wordwrap to columns metric descriptions and expressions; - remove unnecessary whitespace after PMU event names; - the metric filter is a glob but matched using strstr which will always fail, switch to using a proper globmatch, - the detail flag gives details for extra kernel PMU events like branch-instructions. In metricgroup.c switch from struct mep being a rbtree of metricgroups containing a list of metrics, to the tree directly containing all the metrics. In general the alias for a name is passed to the print routine rather than being contained in the name with OR.

The sqrtloop creates a child process to run an infinite loop calling sqrt() with rand(). This is needed for ARM SPE fork test. $ perf test -w sqrtloop It can take an optional argument to specify how long it will run in seconds (default: 1). Committer notes: Explicitely ignored the sqrt() return to fix the build on systems where the compiler complains it isn't being used. And added a sqrtloop specific CFLAGS to disable optimizations to make this a bit more robust wrt dead code elimination. Doing that a -U_FORTIFY_SOURCE needs to be added, as -O0 is incompatible with it. Signed-off-by:
