| Subject | [PATCH V2] arm64: kconfig: allow support for memory failure handling |
| Message-ID | <tdslX-1bG-5@gated-at.bofh.it> |
From: "Jonathan (Zhixiong) Zhang" <zjzhang@codeaurora.org> If ACPI_APEI and MEMORY_FAILURE is configured, select ACPI_APEI_MEMORY_FAILURE. This enables memory failure recovery when such memory failure is reported through ACPI APEI. APEI (ACPI Platform Error Interfaces) provides a means for the platform to convey error information to the kernel. Declare ARCH_SUPPORTS_MEMORY_FAILURE, as arm64 does support memory failure recovery attempt.

Yap, looks ok to me: we're basically enabling
ghes_handle_memory_failure() to queue a memory address at fault for
possibly offlining on arm64. And since the arch supports it...
