Subject: [PATCH 0/4] ACPI: Serialize EC queries, UCSI and ideapad methods
Date: Wed, 14 Oct 2026 22:04:52 +0300	[thread overview]
Message-ID: <20261014190544.150093-1-aliamemis@disroot.org> (raw)

This goes on top of [1] and uses its exclusive helpers for the other
users of the shared EC mutex in bko221065: the _Qxx methods, the UCSI
_DSM and the ideapad-laptop methods, as discussed in [2].

Patches 3 and 4 depend on patch 1 and on [1], so it is probably easiest
to take the whole set through the ACPI tree.

The ideapad part is only build-tested, so it would be great if someone
with one of the bko221065 machines could try both series together.
