When boot with "init=/sbin/bootchartd" as below: # runqemu qemux86 bootparams="init=/sbin/bootchartd" There are two bootchartd process after boot [1]. # ps -ef | grep bootchart root 101 1 0 03:27 ? 00:00:00 /bin/sh /sbin/bootchartd root 103 101 8 03:27 ? 00:00:02 /lib64/bootchart/bootchart-collector 50 root 106 1 0 03:27 ? 00:00:00 /bin/sh /sbin/bootchartd root 792 106 0 03:27 ? 00:00:00 /lib64/bootchart/bootchart-collector --usleep 1000000 root 794 725 0 03:27 ttyS0 00:00:00 grep bootchart # /sbin/bootchartd stop [bootchart] bootchart-collector started as pid 596 with 2 args: [bootchart] '--dump' [bootchart] '/tmp/bootchart.3lXpVDAq3v' [bootchart] Extracting profile data from pid 204 [bootchart] map 0xbed9a000 -> 0xbedbb000 size: 132k from 'bed9a000' 'bedbb000' [bootchart] read 135168 bytes of 135168 [bootchart] reading 150 chunks (of 150) ...

After patch: # ps -ef | grep bootchart root 101 1 0 03:36 ? 00:00:00 /bin/sh /sbin/bootchartd root 103 101 6 03:36 ? 00:00:04 /lib64/bootchart/bootchart-collector 50 root 596 592 0 03:37 ttyS0 00:00:00 grep bootchart [1] https://github.com/xrmx/bootchart/issues/94 (From OE-Core rev: 058d6f5e6186c136c834fdb1303e28c6b9402ccd) Signed-off-by: Mingli Yu <mingli.yu@windriver.com> Signed-off-by: Richard Purdie <richard.purdie@linuxfoundation.org> (cherry picked from commit cc34e3bdedc045baf97ebc2258295d9433cb332e) Signed-off-by: Steve Sakoman <steve@sakoman.com> Signed-off-by: Richard Purdie <richard.purdie@linuxfoundation.org>
QEMU Emulation Targets ====================== To simplify development, the build system supports building images to work with the QEMU emulator in system emulation mode. Several architectures are currently supported in 32 and 64 bit variants: * ARM (qemuarm + qemuarm64) * x86 (qemux86 + qemux86-64) * PowerPC (qemuppc only) * MIPS (qemumips + qemumips64) Use of the QEMU images is covered in the Yocto Project Reference Manual. The appropriate MACHINE variable value corresponding to the target is given in brackets.
