Subject: [PATCH] acpi/_DSM: Add rev/func to warning message when acpi_evaluate_dsm failed.
Date: Tue, 27 Aug 2024 07:34:37 +0800 [thread overview]
Message-ID: <20240826233437.19632-1-00107082@163.com> (raw)
When acpi_evaluate_dsm failed, the warning message lacks the rev
and func information which is available and helpful.
For example, iwlwifi would make _DSM queries for lari config,
and when it failed, all warning messages are all the same:
ACPI: \: failed to evaluate _DSM bf0212f2-788f-c64d-a5b3-1f738e285ade (0x1001)
ACPI: \: failed to evaluate _DSM bf0212f2-788f-c64d-a5b3-1f738e285ade (0x1001)

ACPI: \: failed to evaluate _DSM bf0212f2-788f-c64d-a5b3-1f738e285ade (0x1001)
With this patch, the warnings would be more informative:
ACPI: \: failed to evaluate _DSM bf0212f2-788f-c64d-a5b3-1f738e285ade rev:0 func:1 (0x1001)

ACPI: \: failed to evaluate _DSM bf0212f2-788f-c64d-a5b3-1f738e285ade rev:0 func:12 (0x1001)
