Thanks for the reply. It's not very easy to see. It's just a bit down from the link you sent. It's the last possible action in the Serialization Actions table: https://uefi.org/specs/ACPI/6.5/18_Platform_Error_Interfaces.html#serialization-actions 18.5.1.1. Serialization Actions GET_EXECUTE-_OPERATION_TIMINGS Returns an encoded QWORD: [63:32] value in microseconds that the platform expects would be the maximum amount of time it will take to process and complete an EXECUTE_OPERATION. [31:0] value in microseconds that the platform expects would be the nominal amount of time it will take to process and complete an EXECUTE_OPERATION. -----Original Message----- From: Luck, Tony <tony.luck@xxxxxxxxx> Sent: Friday, August 4, 2023 10:31 AM To: Jeshua Smith <jeshuas@xxxxxxxxxx>; keescook@xxxxxxxxxxxx; gpiccoli@xxxxxxxxxx; rafael@xxxxxxxxxx; lenb@xxxxxxxxxx; james.morse@xxxxxxx; bp@xxxxxxxxx Cc: linux-acpi@xxxxxxxxxxxxxxx; linux-kernel@xxxxxxxxxxxxxxx; linux-hardening@xxxxxxxxxxxxxxx; linux-tegra@xxxxxxxxxxxxxxx; Thierry Reding <treding@xxxxxxxxxx>; Jonathan Hunter <jonathanh@xxxxxxxxxx> Subject: RE: [PATCH V2] ACPI: APEI: Use ERST timeout for slow devices External email: Use caution opening links or attachments > Can the maintainers please respond to my patch?
