Subject: [GIT PULL] KVM/arm64 updates for 7.2
Date: Fri, 12 Jun 2026 09:48:35 +0100 [thread overview]
Message-ID: <20260612084835.2992552-1-maz@kernel.org> (raw)
Paolo,
This is a bit of an odd merge window on the KVM/arm64 front. There is
absolutely no new feature in the pull request. It is purely fixes,
because it is simply becoming too hard to review new stuff when so
many AI-fuelled fixes hit the list. And even then, I've arbitrarily
tagged the branch today, knowing that there is quite a backlog of
fixes that I will send very shortly, probably before -rc1.
So here it is: only fixes and very minor improvements, all over the
place. Details in the tag below.
Please pull,
M.
The following changes since commit 5200f5f493f79f14bbdc349e402a40dfb32f23c8:

Merge branch kvm-arm64/nv-mmu-7.2 into kvmarm-master/next (2026-06-12 09:29:34 +0100)
----------------------------------------------------------------
KVM/arm64 updates for 7.2
* New features:
- None. Zilch. Nada. Que dalle.
* Fixes and other improvements:
- Significant cleanup of the vgic-v5 PPI support which was merged in
7.1. This makes the code more maintainable, and squashes a couple
of bugs in the meantime.
- Set of fixes for the handling of the MMU in an NV context,
particularly VNCR-triggered faults. S1POE support is fixed
as well.
- Large set of pKVM fixes, mostly addressing recurring issues
around hypervisor tracking of donated pages in obscure cases
where the donation could fail and leave things in a bizarre
state.
- Fixes for the so-called "lazy vgic init", which resulted in
sleeping operations in non-preemptible sections. This turned
out to be far more invasive than initially expected...
- Reduce the overhead of L1/L2 context switch by not touching
the FP registers.
- Fix the way non-implemented page sizes are dealt with when
a guest insist on using them for S2 translation.
- The usual set of low-impact fixes and cleanups all over the map.
