|
KVM/riscv changes for 6.11
- Redirect AMO load/store access fault traps to guest
- Perf kvm stat support for RISC-V
- Use guest files for IMSIC virtualization, when available
ONE_REG support for the Zimop, Zcmop, Zca, Zcf, Zcd, Zcb and Zawrs ISA
extensions is coming through the RISC-V tree.

Pre-population has been requested several times to mitigate KVM page faults
during guest boot or after live migration. It is also required by TDX
before filling in the initial guest memory with measured contents.
Introduce it as a generic API.
|
|
Add a test case to exercise KVM_PRE_FAULT_MEMORY and run the guest to access the
pre-populated area. It tests KVM_PRE_FAULT_MEMORY ioctl for KVM_X86_DEFAULT_VM
and KVM_X86_SW_PROTECTED_VM.

Wire KVM_PRE_FAULT_MEMORY ioctl to kvm_mmu_do_page_fault() to populate guest
memory. It can be called right after KVM_CREATE_VCPU creates a vCPU,
since at that point kvm_mmu_create() and kvm_init_mmu() are called and
the vCPU is ready to invoke the KVM page fault handler.
The helper function kvm_tdp_map_page() takes care of the logic to
process RET_PF_* return values and convert them to success or errno.

Move the accounting of the result of kvm_mmu_do_page_fault() to its
callers, as only pf_fixed is common to guest page faults and async #PFs,
and upcoming support KVM_PRE_FAULT_MEMORY won't bump _any_ stats.

Account stat.pf_taken in kvm_mmu_page_fault(), i.e. the actual page fault
handler, instead of conditionally bumping it in kvm_mmu_do_page_fault().
The "real" page fault handler is the only path that should ever increment
the number of taken page faults, as all other paths that "do page fault"
are by definition not handling faults that occurred in the guest.

Add a new ioctl KVM_PRE_FAULT_MEMORY in the KVM common code. It iterates on the
memory range and calls the arch-specific function. The implementation is
optional and enabled by a Kconfig symbol.

Adds documentation of KVM_PRE_FAULT_MEMORY ioctl. [1]
It populates guest memory. It doesn't do extra operations on the
underlying technology-specific initialization [2]. For example,
CoCo-related operations won't be performed. Concretely for TDX, this API
won't invoke TDH.MEM.PAGE.ADD() or TDH.MR.EXTEND(). Vendor-specific APIs
are required for such operations.
The key point is to adapt of vcpu ioctl instead of VM ioctl. First,
populating guest memory requires vcpu. If it is VM ioctl, we need to pick
one vcpu somehow. Secondly, vcpu ioctl allows each vcpu to invoke this
ioctl in parallel. It helps to scale regarding guest memory size, e.g.,
hundreds of GB.

A rename and refactoring extracted from the preparatory series for
Intel TDX support in KVM's MMU.
|

The flags AS_UNMOVABLE and AS_INACCESSIBLE were both added just for guest_memfd;
AS_UNMOVABLE is already in existing versions of Linux, while AS_INACCESSIBLE was
acked for inclusion in 6.11.
But really, they are the same thing: only guest_memfd uses them, at least for
now, and guest_memfd pages are unmovable because they should not be
accessed by the CPU.
So merge them into one; use the AS_INACCESSIBLE name which is more comprehensive.
At the same time, this fixes an embarrassing bug where AS_INACCESSIBLE was used
as a bit mask, despite it being just a bit index.
The bug was mostly benign, because AS_INACCESSIBLE's bit representation (1010)
corresponded to setting AS_UNEVICTABLE (which is already set) and AS_ENOSPC
(except no async writes can happen on the guest_memfd). So the AS_INACCESSIBLE
flag simply had no effect.
Fixes: 1d23040caa8b ("KVM: guest_memfd: Use AS_INACCESSIBLE when creating guest_memfd inode")
Fixes: c72ceafbd12c ("mm: Introduce AS_INACCESSIBLE for encrypted/confidential memory")

Per-cpu struct kvm_steal_time is added here, its size is 64 bytes and
also defined as 64 bytes, so that the whole structure is in one physical
page.
When a VCPU is online, function pv_enable_steal_time() is called. This
function will pass guest physical address of struct kvm_steal_time and
tells hypervisor to enable steal time. When a vcpu is offline, physical
address is set as 0 and tells hypervisor to disable steal time.
Here is an output of vmstat on guest when there is workload on both host
and guest. It shows steal time stat information.

Add ParaVirt steal time feature in host side, VM can search supported
features provided by KVM hypervisor, a feature KVM_FEATURE_STEAL_TIME
is added here. Like x86, steal time structure is saved in guest memory,
one hypercall function KVM_HCALL_FUNC_NOTIFY is added to notify KVM to
enable this feature.
One CPU attr ioctl command KVM_LOONGARCH_VCPU_PVTIME_CTRL is added to
save and restore the base address of steal time structure when a VM is
migrated.

Function kvm_map_page_fast() is fast path of secondary mmu page fault
flow, pfn is parsed from secondary mmu page table walker. However the
corresponding page reference is not added, it is dangerious to access
page out of mmu_lock.
Here page ref is added inside mmu_lock, function kvm_set_pfn_accessed()
and kvm_set_pfn_dirty() is called with page ref added, so that the page
will not be freed by others.
Also kvm_set_pfn_accessed() is removed here since it is called in the
following function kvm_release_pfn_clean().

When updating pmd entry such as allocating new pmd page or splitting
huge page into normal page, it is necessary to firstly update all pte
entries, and then update pmd entry.
It is weak order with LoongArch system, there will be problem if other
VCPUs see pmd update firstly while ptes are not updated. Here smp_wmb()
is added to assure this.

Currently page level selection about secondary mmu depends on memory
slot and page level about host mmu. There will be problems if page level
of secondary mmu is zero already. Huge page cannot be selected if there is
normal page mapped in secondary mmu already, since it is not supported to
merge normal pages into huge pages now.
So page level selection should depend on the following three conditions.
1. Memslot is aligned for huge page and vm is not migrating.
2. Page level of host mmu is also huge page.
3. Page level of secondary mmu is suituable for huge page.

With hardware assisted virtualization, there are two level HW mmu, one
is GVA to GPA mapping, the other is GPA to HPA mapping which is called
secondary mmu in generic. If there is page fault for secondary mmu,
there needs tlb flush operation indexed with fault GPA address and VMID.
VMID is stored at register CSR.GSTAT and will be reload or recalculated
before guest entry.
Currently CSR.GSTAT is not saved and restored during VCPU context
switch, instead it is recalculated during guest entry. So CSR.GSTAT is
effective only when a VCPU runs in guest mode, however it may not be
effective if the VCPU exits to host mode. Since register CSR.GSTAT may
be stale, it may records the VMID of the last schedule-out VCPU, rather
than the current VCPU.
Function kvm_flush_tlb_gpa() should be called with its real VMID, so
here move it to the guest entrance. Also an arch-specific request id
KVM_REQ_TLB_FLUSH_GPA is added to flush tlb for secondary mmu, and it
can be optimized if VMID is updated, since all guest tlb entries will
be invalid if VMID is updated.

Currently interrupts are posted and cleared with the asynchronous mode,
meanwhile they are saved in SW state vcpu::arch::irq_pending and vcpu::
arch::irq_clear. When vcpu is ready to run, pending interrupt is written
back to CSR.ESTAT register from SW state vcpu::arch::irq_pending at the
guest entrance.
During VM migration stage, vcpu is put into stopped state, however
pending interrupts are not synced to CSR.ESTAT register. So there will
be interrupt lost when VCPU is migrated to another host machines.
Here in this patch when ESTAT CSR register is read from VMM user mode,
pending interrupts are synchronized to ESTAT also. So that VMM can get
correct pending interrupts.

Currently building the powerpc selftests with USERCFLAGS set to anything
causes the build to break:
$ make -C tools/testing/selftests/powerpc V=1 USERCFLAGS=-Wno-error
...
gcc -Wno-error cache_shape.c ...
cache_shape.c:18:10: fatal error: utils.h: No such file or directory
18 | #include "utils.h"
| ^~~~~~~~~
compilation terminated.
This happens because the USERCFLAGS are added to CFLAGS in lib.mk, which
causes the check of CFLAGS in powerpc/flags.mk to skip setting CFLAGS at
all, resulting in none of the usual CFLAGS being passed. That can
be seen in the output above, the only flag passed to the compiler is
-Wno-error.
Fix it by dropping the conditional setting of CFLAGS in flags.mk.
Instead always set CFLAGS, but also append USERCFLAGS if they are set.
Note that appending to CFLAGS (with +=) wouldn't work, because flags.mk
is included by multiple Makefiles (to support partial builds), causing
CFLAGS to be appended to multiple times. Additionally that would place
the USERCFLAGS prior to the standard CFLAGS, meaning the USERCFLAGS
couldn't override the standard flags. Being able to override the
standard flags is desirable, for example for adding -Wno-error.
With the fix in place, the CFLAGS are set correctly, including the
USERCFLAGS:
$ make -C tools/testing/selftests/powerpc V=1 USERCFLAGS=-Wno-error
...

git://git.kernel.org/pub/scm/linux/kernel/git/andi.shyti/linux into i2c/for-current
This tag includes a nice fix in the PNX driver that has been
pending for a long time. Piotr has replaced a potential lock in
the interrupt context with a more efficient and straightforward
handling of the timeout signaling.

DTS for Nokia N900 incorrectly specifies "active high" polarity for
the reset line, while the chip documentation actually specifies it as
"active low". In the past the driver fudged gpiod API and inverted
the logic internally, but it was changed in d0d89493bff8.

Unless tpm_chip_bootstrap() was called by the driver, !chip->auth can
cause a null derefence in tpm_buf_hmac_session*(). Thus, address
!chip->auth in tpm_buf_hmac_session*() and remove the fallback
implementation for !TCG_TPM2_HMAC.

Pull networking fixes from Jakub Kicinski:
"Including fixes from bluetooth, wireless and netfilter.
There's one fix for power management with Intel's e1000e here,
Thorsten tells us there's another problem that started in v6.9. We're
trying to wrap that up but I don't think it's blocking.
Current release - new code bugs:
- wifi: mac80211: disable softirqs for queued frame handling
- af_unix: fix uninit-value in __unix_walk_scc(), with the new
garbage collection algo
Previous releases - regressions:
- Bluetooth:
- qca: fix BT enable failure for QCA6390 after warm reboot
- add quirk to ignore reserved PHY bits in LE Extended Adv Report,
abused by some Broadcom controllers found on Apple machines
- wifi: wilc1000: fix ies_len type in connect path
Previous releases - always broken:
- tcp: fix DSACK undo in fast recovery to call tcp_try_to_open(),
avoid premature timeouts
- net: make sure skb_datagram_iter maps fragments page by page, in
case we somehow get compound highmem mixed in
- eth: bnx2x: fix multiple UBSAN array-index-out-of-bounds when more
queues are used
Misc:
- MAINTAINERS: Remembering Larry Finger"
