Hi Linu,
You need to add this path into TARGETS for make install to work:
TARGETS += drivers/dma-buf
+TARGETS += drivers/hwtracing/coresight
TARGETS += drivers/s390x/uvdevice
create mode 100755 tools/testing/selftests/drivers/hwtracing/coresight/sysfs_test_trace.sh

Looks like you still need the skip for TPIU here the same as the Perf
test. It's an external sink and doesn't have a readable file so the test
fails.
With those changes, looks good. Thanks for adding the first sysfs test.
Hopefully we can expand them more in the future.
