[PATCH 0/3] ACPI: Serialize battery methods and INT3403 _TMP
From: Ali Ahmet Memiş
Date: Wed Oct 14 2026 - 09:49:41 EST
As discussed in [1], add exclusive variants of acpi_evaluate_object()
and acpi_evaluate_integer() and use them for the battery methods and
INT3403 _TMP, which interleave badly on ThinkPad P1 Gen2 and P53.
UCSI (bko221065) is not converted. There the contention is on a
firmware AML mutex that _Qxx EC queries also take, which a wrapper
around acpi_evaluate_object() cannot cover, and Rong's notification
merging in 7.3 already reduces it on the battery side.
