Hi Anju ,

The above test kernel add issue while setting up, so rebuilt the upstream kernel with the patches mentioned above.

=> Perf fuzzer works fine and issue is not seen.

=> Thread IMC also works fine.

root@ltc-wspoon4:/usr/lib/linux-tools-4.15.0-20# ./perf stat -e '{emulation-faults, thread_imc/CPM_CCYC/, thread_imc/CPM_CS_32MHZ_CYC/, thread_imc/CPM_CS_BRU_CMPL_KERNEL/}' yes > /dev/null

^Cyes: Interrupt
