| Testing Error Detection and Correction |
| ###################################### |
| Tests verify API and use error injection method to inject |
| errors. |
| |
| Prerequisites |
| ************* |
| IBECC should be enabled in BIOS. This is usually enabled in the default |
| BIOS configuration. Verify following: |
| Intel Advanced Menu -> Memory Configuration -> In-Band ECC -> <Enabled>. |
| Verify also operational mode with: |
| Intel Advanced Menu -> Memory Configuration -> In-Band ECC Operation Mode -> 2 |
| |
| For injection test Error Injection should be enabled. |
| |
| Error Injection |
| =============== |
| IBECC includes a feature to ease the verification effort such as Error |
| Injection capability. This helps to test the error checking, logging and |
| reporting mechanism within IBECC. |
| |
| In order to use Error Injection user need to use BIOS Boot Guard 0 profile. |
| |
| Additionally Error Injection need to be enabled in the following BIOS menu: |
| Intel Advanced Menu -> Memory Configuration -> In-Band ECC Error -> <Enabled>. |
| |
| Configurations |
| ************** |
| Due to high security risk Error Injection capability should not be |
| enabled for production. Due to this reason test has production configuration |
| and debug configuration. The main difference is that debug configuration |
| includes Error Injection. |
