2023-09-26tests/shell: Fix shellcheck warnings for SC2153 in multiple scriptsAthira Rajeev5-0/+5
Running shellcheck on some of the shell scripts, throws below warning on shellcheck v0.6. Example: In tests/shell/coresight/asm_pure_loop.sh line 14: DATA="$DATD/perf-$TEST-$DATV.data" ^---^ SC2153: Possible misspelling: DATD may not be assigned, but DATA is. Here, DATD is exported from "lib/coresight.sh" and this warning can be ignored. Use "shellcheck disable=" to ignore this check.

2022-10-06perf test: Add build infra for perf test tools for ARM CoreSight testsCarsten Haitzler2-0/+39
This adds the initial build infrastructure (makefiles maintainers information) for adding follow-on tests for CoreSight. Committer notes: Remove the installation of tests/shell/coresight/*.sh, as there are no files there yet and thus, at this point, make install fails. Use $(QUIET_CLEAN) to avoid having extraneous output in the 'make clean' output. Also use @$(MAKE) in tools/perf/tests/shell/coresight/Makefile as $(Q) is not turning into @ when V=1 isn't used, i.e. in the default case it is not being quiet. The >/dev/null in the all for tools/perf/tests/shell/coresight/Makefile is to avoid this: make[4]: Nothing to be done for 'all'. make[4]: Nothing to be done for 'all'. make[4]: Nothing to be done for 'all'. DESCEND plugins GEN /tmp/build/perf/python/perf.so make[4]: Nothing to be done for 'all'. INSTALL trace_plugins On !arm64 where nothing is done on the main target for tools/perf/tests/shell/coresight/*/Makefile.
