| |
When 'osc_sb_apei_support_acked' is set, it indicates that the platform supports APEI, firmware-first mode, as ACPI _OSC capability bit 4, APEI Support, was set in query. While _OSC is an optional method, platforms with APEI support should implement it to inform its capability to the OS properly.
Add check to 'osc_sb_apei_support_acked' before calling ghes_edac_register() to restrict that ghes_edac is enabled on platforms with APEI support capability set in _OSC.
