Hi, To run the Kselftest pstore test suite I use following: Hardware: Freedom U540 Architecture: RISCV Kernel: 5.4.3 Steps followed to run the test: 1.Cloning linux kernel sources from https://github.com/torvalds/linux.git 2.Extracting it. 3.From the cloned kernel source top directory running: # make -C tools/testing/selftests/ TARGETS=pstore run_tests Following is the log: make: Entering directory '/mnt/linux-master/tools/testing/selftests' make --no-builtin-rules ARCH=riscv -C ../../.. headers_install make[1]: Entering directory '/mnt/linux-master' INSTALL ./usr/include make[1]: Leaving directory '/mnt/linux-master' make[1]: Entering directory '/mnt/linux-master/tools/testing/selftests/pstore' make[1]: Nothing to be done for 'all'. make[1]: Leaving directory '/mnt/linux-master/tools/testing/selftests/pstore' make[1]: Entering directory '/mnt/linux-master/tools/testing/selftests/pstore' TAP version 13 1..2 # selftests: pstore: pstore_tests # === Pstore unit tests (pstore_tests) === # UUID=a5947bf3-bc04-4175-ac85-4056024cbc4b # Checking pstore backend is registered ... ok # backend=(null) # cmdline=earlycon=sbi earlycon=sbi root=/dev/mmcblk0p3 rootwait console=ttySIF0 console=tty0 # Checking pstore console is registered ...
