Subject: [PATCH v2 00/17] arm64: Use EL2 virtual timer when running VHE
Date: Thu, 14 May 2026 16:09:28 +0100 [thread overview]
Message-ID: <20260514150945.3917510-1-maz@kernel.org> (raw)
This is the second version of the series initially posted at [1],
which
- updates the ACPI GTDT parsing to deal the v3 layout and the EL2
virtual timer,
- moves the architected timer driver to use it when running VHE,
- fixes a number of DTs to reflect the reality of the HW.
Patches based on -rc3, tested on Amlogic SM1, QC X1E, Ampere Altra,
and Apple M2.
* From v1:
- Now also using the EL2 virtual counter, which further improve
things when running at a deeper nesting level
- Updated consistency checks for the platform timers when finding a
GTDTv3
- Collected ABs and RBs, with thanks
