selftests/pstore: add pstore test scripts going with reboot

2015-10-16T02:00:32Z

To test pstore in earnest, we have to cause kernel crash and check pstore filesystem after reboot. We add two scripts: - pstore_crash_test This script causes kernel crash and reboot. It is executed by 'make run_pstore_crash' in selftests. It can also be used with kdump. - pstore_post_reboot_tests This script includes test cases which check pstore's behavior after crash and reboot. It is executed together with pstore_tests by 'make run_tests [-C pstore]' in selftests. The test cases in pstore_post_reboot_tests are currently following. - Check pstore backend is registered - Mount pstore filesystem - Check dmesg/console/pmsg files exist in pstore filesystem - Check dmesg/console files contain oops end marker - Check pmsg file properly keeps the content written before crash - Remove all files in pstore filesystem Example usage is following. (before reboot) # cd /path/to/selftests # make run_tests -C pstore === Pstore unit tests (pstore_tests) === UUID=b49b02cf-b0c2-4309-be43-b08c3971e37f ... selftests: pstore_tests [PASS] === Pstore unit tests (pstore_post_reboot_tests) === UUID=953eb1bc-8e03-48d7-b27a-6552b24c5b7e Checking pstore backend is registered ... ok backend=ramoops cmdline=console=ttyS0,115200 root=/dev/mmcblk0p2 rw rootwait mem=768M ramoops.mem_address=0x30000000 ramoops.mem_size=0x10000 pstore_crash_test has not been executed yet. we skip further tests. selftests: pstore_post_reboot_tests [PASS] # make run_pstore_crash === Pstore unit tests (pstore_crash_test) === UUID=93c8972d-1466-430b-8c4a-28d8681e74c6 Checking pstore backend is registered ... ok backend=ramoops cmdline=console=ttyS0,115200 root=/dev/mmcblk0p2 rw rootwait mem=768M ramoops.mem_address=0x30000000 ramoops.mem_size=0x10000 Causing kernel crash ...
