Subject: [GIT PULL] First batch of KVM changes for Linux 6.10 merge window
Linus,
The following changes since commit dd5a440a31fae6e459c0d6271dddd62825505361:
Linux 6.9-rc7 (2024-05-05 14:06:01 -0700)
are available in the Git repository at:
https://git.kernel.org/pub/scm/virt/kvm/kvm.git tags/for-linus

selftests/kvm: remove dead file (2024-05-15 13:40:16 -0400)
(Yes, the top commit is something I noticed right now while preparing
this message and reviewing the diffstat. The patch itself is innocuous,
but still---guilty as charged).
There is a small semantic conflict that you will have to fix on merge:
diff --git a/arch/x86/kvm/vmx/main.c b/arch/x86/kvm/vmx/main.c
index 7c546ad3e4c9..d4ed681785fd 100644

#include "nested.h"
#include "pmu.h"
+#include "posted_intr.h"
#define VMX_REQUIRED_APICV_INHIBITS \
(BIT(APICV_INHIBIT_REASON_DISABLE)| \
What happened is that commit 699f67512f04 ("KVM: VMX: Move posted
interrupt descriptor out of VMX code", from the tip tree) removed the
posted_intr.h include from vmx.h, and now the line has to be added back
into a .c file that is new in this merge.
Compared to the kvm/next branch which is included in linux-next, support
for AMD SEV-SNP is missing from this pull request. I prepared this
tag a few days ago and at the time I wanted to double check that my
comaintainer agreed it was ready---both implementation and UAPI-wise.
I left it out of the tag for the time being, but we have discussed it
since and it will arrive early next week.
Thanks,
Paolo
----------------------------------------------------------------
ARM:
* Move a lot of state that was previously stored on a per vcpu
basis into a per-CPU area, because it is only pertinent to the
host while the vcpu is loaded. This results in better state
tracking, and a smaller vcpu structure.
* Add full handling of the ERET/ERETAA/ERETAB instructions in
nested virtualisation. The last two instructions also require
emulating part of the pointer authentication extension.
As a result, the trap handling of pointer authentication has
been greatly simplified.
* Turn the global (and not very scalable) LPI translation cache
into a per-ITS, scalable cache, making non directly injected
LPIs much cheaper to make visible to the vcpu.
* A batch of pKVM patches, mostly fixes and cleanups, as the
upstreaming process seems to be resuming. Fingers crossed!
* Allocate PPIs and SGIs outside of the vcpu structure, allowing
for smaller EL2 mapping and some flexibility in implementing
more or less than 32 private IRQs.
* Purge stale mpidr_data if a vcpu is created after the MPIDR
map has been created.
* Preserve vcpu-specific ID registers across a vcpu reset.
* Various minor cleanups and improvements.
LoongArch:
* Add ParaVirt IPI support.
* Add software breakpoint support.
* Add mmio trace events support.
RISC-V:
* Support guest breakpoints using ebreak
* Introduce per-VCPU mp_state_lock and reset_cntx_lock
* Virtualize SBI PMU snapshot and counter overflow interrupts
* New selftests for SBI PMU and Guest ebreak
* Some preparatory work for both TDX and SNP page fault handling.
This also cleans up the page fault path, so that the priorities
of various kinds of fauls (private page, no memory, write
to read-only slot, etc.) are easier to follow.
x86:
* Minimize amount of time that shadow PTEs remain in the special
REMOVED_SPTE state. This is a state where the mmu_lock is held for
reading but concurrent accesses to the PTE have to spin; shortening
its use allows other vCPUs to repopulate the zapped region while
the zapper finishes tearing down the old, defunct page tables.
* Advertise the max mappable GPA in the "guest MAXPHYADDR" CPUID field,
which is defined by hardware but left for software use. This lets KVM
communicate its inability to map GPAs that set bits 51:48 on hosts
without 5-level nested page tables. Guest firmware is expected to
use the information when mapping BARs; this avoids that they end up at
a legal, but unmappable, GPA.
* Fixed a bug where KVM would not reject accesses to MSR that aren't
supposed to exist given the vCPU model and/or KVM configuration.
* As usual, a bunch of code cleanups.
x86 (AMD):
* Implement a new and improved API to initialize SEV and SEV-ES VMs, which
will also be extendable to SEV-SNP. The new API specifies the desired
encryption in KVM_CREATE_VM and then separately initializes the VM.
The new API also allows customizing the desired set of VMSA features;
the features affect the measurement of the VM's initial state, and
therefore enabling them cannot be done tout court by the hypervisor.
While at it, the new API includes two bugfixes that couldn't be
applied to the old one without a flag day in userspace or without
affecting the initial measurement. When a SEV-ES VM is created with
the new VM type, KVM_GET_REGS/KVM_SET_REGS and friends are
rejected once the VMSA has been encrypted. Also, the FPU and AVX
state will be synchronized and encrypted too.
* Support for GHCB version 2 as applicable to SEV-ES guests. This, once
more, is only accessible when using the new KVM_SEV_INIT2 flow for
initialization of SEV-ES VMs.
x86 (Intel):
* An initial bunch of prerequisite patches for Intel TDX were merged.
They generally don't do anything interesting. The only somewhat user
visible change is a new debugging mode that checks that KVM's MMU
never triggers a #VE virtualization exception in the guest.
* Clear vmcs.EXIT_QUALIFICATION when synthesizing an EPT Misconfig VM-Exit to
L1, as per the SDM.
Generic:
* Use vfree() instead of kvfree() for allocations that always use vcalloc()
or __vcalloc().
* Remove .change_pte() MMU notifier - the changes to non-KVM code are
small and Andrew Morton asked that I also take those through the KVM
tree. The callback was only ever implemented by KVM (which was also the
original user of MMU notifiers) but it had been nonfunctional ever since
calls to set_pte_at_notify were wrapped with invalidate_range_start
and invalidate_range_end... in 2012.
Selftests:
* Enhance the demand paging test to allow for better reporting and stressing
of UFFD performance.
* Convert the steal time test to generate TAP-friendly output.
* Fix a flaky false positive in the xen_shinfo_test due to comparing elapsed
time across two different clock domains.
* Skip the MONITOR/MWAIT test if the host doesn't actually support MWAIT.
* Avoid unnecessary use of "sudo" in the NX hugepage test wrapper shell
script, to play nice with running in a minimal userspace environment.
* Allow skipping the RSEQ test's sanity check that the vCPU was able to
complete a reasonable number of KVM_RUNs, as the assert can fail on a
completely valid setup. If the test is run on a large-ish system that is
otherwise idle, and the test isn't affined to a low-ish number of CPUs, the
vCPU task can be repeatedly migrated to CPUs that are in deep sleep states,
which results in the vCPU having very little net runtime before the next
migration due to high wakeup latencies.
* Define _GNU_SOURCE for all selftests to fix a warning that was introduced by
a change to kselftest_harness.h late in the 6.9 cycle, and because forcing
every test to #define _GNU_SOURCE is painful.
* Provide a global pseudo-RNG instance for all tests, so that library code can
generate random, but determinstic numbers.
* Use the global pRNG to randomly force emulation of select writes from guest
code on x86, e.g. to help validate KVM's emulation of locked accesses.
* Allocate and initialize x86's GDT, IDT, TSS, segments, and default exception
handlers at VM creation, instead of forcing tests to manually trigger the
related setup.
Documentation:
* Fix a goof in the KVM_CREATE_GUEST_MEMFD documentation.
