Subject: [GIT PULL] First batch of KVM changes for Linux 6.12
Linus,
The following changes since commit da3ea35007d0af457a0afc87e84fddaebc4e0b63:
Linux 6.11-rc7 (2024-09-08 14:50:28 -0700)
are available in the Git repository at:
https://git.kernel.org/pub/scm/virt/kvm/kvm.git tags/for-linus-non-x86
for you to fetch changes up to 0cdcc99eeaedf2422c80d75760293fdbb476cec1:
Merge tag 'kvm-riscv-6.12-1' of https://github.com/kvm-riscv/linux into HEAD (2024-09-15 02:43:17 -0400)
These are the non-x86 changes (mostly ARM, as is usually the case).
The generic and x86 changes will come later, in the meanwhile
here is what's ready in case it helps you intersecting the
travelling and pulling schedule. There is a trivial conflict in
arch/arm64/include/asm/kvm_host.h with the arm64 tree.
I'll also send a revert for 6.11 in a few minutes.
Thanks,
Paolo
----------------------------------------------------------------
ARM:
* New Stage-2 page table dumper, reusing the main ptdump infrastructure
* FP8 support
* Nested virtualization now supports the address translation (FEAT_ATS1A)
family of instructions
* Add selftest checks for a bunch of timer emulation corner cases
* Fix multiple cases where KVM/arm64 doesn't correctly handle the guest
trying to use a GICv3 that wasn't advertised
* Remove REG_HIDDEN_USER from the sysreg infrastructure, making
things little simpler
* Prevent MTE tags being restored by userspace if we are actively
logging writes, as that's a recipe for disaster
* Correct the refcount on a page that is not considered for MTE tag
copying (such as a device)
* When walking a page table to split block mappings, synchronize only
at the end the walk rather than on every store
* Fix boundary check when transfering memory using FFA
* Fix pKVM TLB invalidation, only affecting currently out of tree
code but worth addressing for peace of mind
LoongArch:
* Revert qspinlock to test-and-set simple lock on VM.
* Add Loongson Binary Translation extension support.
* Add PMU support for guest.
* Enable paravirt feature control from VMM.
* Implement function kvm_para_has_feature().
RISC-V:
* Fix sbiret init before forwarding to userspace
* Don't zero-out PMU snapshot area before freeing data
* Allow legacy PMU access from guest
* Fix to allow hpmcounter31 from the guest
