Subject: [PATCH v2 0/3] KVM: arm64: Fixes for timers and pKVM
Date: Sat,  8 Aug 2026 08:58:21 +0000	[thread overview]
Message-ID: <20260808085824.732659-1-smostafa@google.com> (raw)

What started as a  small patch ended up as a 3 patch series thanks
to Sashiko.

First patch from Marc to consolidate the offset calculation,
follow up patches fix issues with non-protected VM and timer
offset and protected VM running with broken CNTVOFF_EL2.

The patches have all the information so I will keep this short.

v1: https://lore.kernel.org/all/20260806150105.4010701-1-smostafa@google.com/
Main changes:
- Add comment based on Fuad review
- Add prefix patches that also fix the non-protected hang properly.

Marc Zyngier (1):
  KVM: arm64: Make timer_get_offset() work in all contexts

Mostafa Saleh (2):
  KVM: arm64: Fix timer offsets for non-protected VMs
  KVM: arm64: Fix hvhe and broken CNTVOFF_EL2
