- Add support for 'slot' based PMU events, paired with new UAPI that
compels the user to select a specific PMU implementation
- Lazy save/restore of vCPU state for pKVM, along with various fixes
and cleanups to the management of vCPU state between the untrusted
host and pKVM hypervisor
- Disable traps of EL1 registers for nested hypervisors when FEAT_NV2p1
is present, guaranteeing that EL2-specific register bits are stateful
in the EL1 counterpart
- Leverage FEAT_NV3 to avoid unnecessary ERET/TLBI traps when the scope
of those instructions remains 'in host' (i.e. L1 kernel/userspace)
- Pile of fixes for the management of the VNCR pseudo-TLB, such as
under-invalidations and races with concurrent TLBIs on other vCPUs
- Consolidate the non-protected and pKVM view of ICH_VTR_EL2 to a
runtime-patched constant, allowing the same data to be shared with
pKVM prior to dropping host privileges
- Considerable pile of LLM-assisted fixes around the shop but mostly in
the VGIC, our in-kernel generator of bugs (and sometimes interrupts)
