Subject: [PATCH v3 7/7] perf trace: Update beautifier script for clone flags
Date: Sun, 10 May 2026 13:23:46 -0700 [thread overview]
Message-ID: <20260510202346.49853-8-namhyung@kernel.org> (raw)
In-Reply-To: <20260510202346.49853-1-namhyung@kernel.org>
According to the change in the sched.h, update the script to generate
the flags array like below. Note that '+1' is needed to detect bitmask
pattern at index 0.
$ cat tools/perf/trace/beauty/generated/clone_flags_array.c
static const char *clone_flags[] = {
[ilog2(0x00000100) + 1] = "VM",
[ilog2(0x00000200) + 1] = "FS",
[ilog2(0x00000400) + 1] = "FILES",
[ilog2(0x00000800) + 1] = "SIGHAND",
[ilog2(0x00001000) + 1] = "PIDFD",
[ilog2(0x00002000) + 1] = "PTRACE",
[ilog2(0x00004000) + 1] = "VFORK",
[ilog2(0x00008000) + 1] = "PARENT",
[ilog2(0x00010000) + 1] = "THREAD",
[ilog2(0x00020000) + 1] = "NEWNS",
[ilog2(0x00040000) + 1] = "SYSVSEM",
[ilog2(0x00080000) + 1] = "SETTLS",
[ilog2(0x00100000) + 1] = "PARENT_SETTID",
[ilog2(0x00200000) + 1] = "CHILD_CLEARTID",
[ilog2(0x00400000) + 1] = "DETACHED",
[ilog2(0x00800000) + 1] = "UNTRACED",
[ilog2(0x01000000) + 1] = "CHILD_SETTID",
[ilog2(0x02000000) + 1] = "NEWCGROUP",
[ilog2(0x04000000) + 1] = "NEWUTS",
[ilog2(0x08000000) + 1] = "NEWIPC",
[ilog2(0x10000000) + 1] = "NEWUSER",
[ilog2(0x20000000) + 1] = "NEWPID",
[ilog2(0x40000000) + 1] = "NEWNET",
[ilog2(0x80000000) + 1] = "IO",
[ilog2(0x00000080) + 1] = "NEWTIME",
[32 + 1] = "CLEAR_SIGHAND",
[33 + 1] = "INTO_CGROUP",
[34 + 1] = "AUTOREAP",
[35 + 1] = "NNP",
[36 + 1] = "PIDFD_AUTOKILL",
[37 + 1] = "EMPTY_MNTNS",
};
This was found by Sashiko during review.
