| OPAL_UNREGISTER_DUMP_REGION |
| =========================== |
| |
| While OPAL_REGISTER_DUMP_REGION registers a region, OPAL_UNREGISTER_DUMP_REGION |
| will unregister a region by region ID. |
| |
| OPAL_UNREGISTER_DUMP_REGION takes one argument: the region ID. |
| |
| A host OS should check OPAL_UNREGISTER_DUMP_REGION is supported through a call to |
| OPAL_CHECK_TOKEN. |
| |
| If OPAL_UNREGISTER_DUMP_REGION is called on a system where the call is present but |
| unsupported, it will return OPAL_UNSUPPORTED. |
| |
| BUGS |
| ---- |
| Some skiboot versions incorrectly returned OPAL_SUCCESS in the case of |
| OPAL_UNREGISTER_DUMP_REGION being supported on a platform (so the call was present) |
| but the call being unsupported for some reason (e.g. on an IBM POWER7 machine). |
