| These are some standalone test programs for various parts of the |
| machine check code: |
| |
| They can be all tested together by running "make test" |
| This requires root rights and a kernel with soft offlining and hard |
| offlining support. |
| |
| To use ttable and tcases you need to specify a linux source tree |
| with the mce improvements patchkit added with make LSRC=/path/to/linux |
| or symlink the linux tree to ../linux |
| |
| The programs requiring kernel sources are not in the all make target. |
| If you want to build them use make requireskernel after you |
| set up the kernel sources or specified LSRC. |
| |
| tcases |
| |
| Simple tester of a few test cases by running the machine check grader code |
| in user space. This is an alternative to the more complete coverage |
| in the main mce-test test cases. |
| |
| Doesn't aim to be complete, but more a quick sanity check, that |
| can be done without booting a kernel. |
| |
| ttable |
| |
| Generate a table of the output of the machine check grader. This gives |
| an overview how all the status bits in the machine check architecture |
| are processed. Note that a few bits are tested outside the grader |
| and this doesn't apply to corrected machine check interrupts. |
| |
| Use make see to render the output using links -g (note this doesn't work |
| with elinks as it is used on many distributions, in this case specify |
| a different browser with make BROWSER=browserbinary see) |
| |
| tinjpage |
| |
| tinjpage is a coverage test for the hwpoison page recovery code |
| in the kernel. It tests different cases by putting pages |
| into different stages, triggering poison injection on them |
| and verifies the results. |
| |
| tinjpage requires a kernel with MADV_POISON injection support and the |
| hwpoison testkit, but doesn't require a kernel tree and can be built directly with |
| make tinjpage |
| |
| A few of the test cases are timing dependent and might require adjustment |
| to run successfully. |
| |
| tinjpage-working |
| |
| Old version of tinjpage that tests much less cases, but might be more reliable. |
| |
| tring |
| |
| Old unit test program for the ring buffer used in mca recovery. |
| Not in default Makefile target. |
