Clarification on support of arm32 with kernel4.1 for oprofile 1.2.0

Hello Team,

Good Day!!!


Cross Compiled the oprofile-1.2.0 in ubuntu.

Configure parameter below :

./configure --host=arm-buildroot-linux-gnueabi \
                --build=i686-linux \

CC=/opt/toolchains/crosstools-arm-gcc-5.3-linux-4.1-glibc-2.22-binutils-2.25/usr/bin/arm-buildroot-linux-gnueabi-gcc
\

CXX=/opt/toolchains/crosstools-arm-gcc-5.3-linux-4.1-glibc-2.22-binutils-2.25/usr/bin/arm-buildroot-linux-gnueabi-g++
\
                --with-binutils=/home/test_binutils_080218/binutils-2.29/ \
                --prefix=$(INSTALL_DIR)/lib/oprofile

once compiled,tested the oprofile binaries in target (arm32 hw running on
kernel-4.1)
Received the following error

*# operf*
*Your kernel does not implement a required syscall for the operf program.*


While checking found that CONFIG_PERF_EVENTS is not set, So enabled the
same and tested the orpfile resulted the following error.


*# operf --help*
*Your kernel's Performance Events Subsystem does not support your processor
type.*


if i change the oprofile-1.2.0 with oprofile 0.9.9 it works fine (oprofile
running in legacy mode)

Can anyone let me understand why oprofile-1.2.0 give " Your kernel's
Performance Events Subsystem does not support your processor type. " error.

Is arm32 not supported in  oprofile-1.2.0  with kernel -4.1?

Please explain this !!!

Thanks in Advance..

Thanks and Regards,
Vinoth Natarajan.
