When acpi_evaluate_dsm() fails, 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 fails, 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) 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) ACPI: \: failed to evaluate _DSM bf0212f2-788f-c64d-a5b3-1f738e285ade (0x1001) ACPI: \: failed to evaluate _DSM bf0212f2-788f-c64d-a5b3-1f738e285ade (0x1001) With this change, 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:6 (0x1001) ACPI: \: failed to evaluate _DSM bf0212f2-788f-c64d-a5b3-1f738e285ade rev:0 func:7 (0x1001) ACPI: \: failed to evaluate _DSM bf0212f2-788f-c64d-a5b3-1f738e285ade rev:0 func:8 (0x1001) ACPI: \: failed to evaluate _DSM bf0212f2-788f-c64d-a5b3-1f738e285ade rev:0 func:3 (0x1001) ACPI: \: failed to evaluate _DSM bf0212f2-788f-c64d-a5b3-1f738e285ade rev:0 func:9 (0x1001) ACPI: \: failed to evaluate _DSM bf0212f2-788f-c64d-a5b3-1f738e285ade rev:0 func:10 (0x1001) ACPI: \: failed to evaluate _DSM bf0212f2-788f-c64d-a5b3-1f738e285ade rev:0 func:12 (0x1001) Signed-off-by: David Wang <00107082@163.com> Link: https://patch.msgid.link/20240826233437.19632-1-00107082@163.com [ rjw: Subject and changelog edits ] Signed-off-by: Rafael J.

Linux kernel ============ There are several guides for kernel developers and users. These guides can be rendered in a number of formats, like HTML and PDF. Please read Documentation/admin-guide/README.rst first. In order to build the documentation, use ``make htmldocs`` or ``make pdfdocs``. The formatted documentation can also be read online at: https://www.kernel.org/doc/html/latest/ There are various text files in the Documentation/ subdirectory, several of them using the reStructuredText markup notation. Please read the Documentation/process/changes.rst file, as it contains the requirements for building and running the kernel, and information about the problems which may result by upgrading your kernel.
