Subject: [PATCH v2 3/7] ACPI / APEI: add OSC APEI bit check for ghes_edac
Date: Thu, 3 Aug 2017 15:57:49 -0600 [thread overview]
Message-ID: <20170803215753.30553-4-toshi.kani@hpe.com> (raw)
In-Reply-To: <20170803215753.30553-1-toshi.kani@hpe.com>
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.
