From mboxrd@z Thu Jan 1 00:00:00 1970 From: ratbert.chuang@gmail.com (Po-Yu Chuang) Date: Fri, 8 Apr 2011 17:35:53 +0800 Subject: [PATCH RFC] util-linux: readprofile: don't stop parsing at __init_end Message-ID: <1302255353-1622-1-git-send-email-ratbert.chuang@gmail.com> To: linux-arm-kernel@lists.infradead.org List-Id: linux-arm-kernel.lists.infradead.org From: Po-Yu Chuang Some architectures like ARM place __init_end before .text section. If any function in .init section is hit while profiling, readprofile stops at __init_end. That means if we enable profiling at boot time, the profiler probably hits init functions and readprofile does not work well unless we reset profiling buffer with -r option.
