When the radix fault handler has no page from the process address space (e.g., for IO memory), it looks up the process pte and sets partition table pte using that to get attributes like CI and guarded. If the process table entry is to be writable, set _PAGE_DIRTY as well to avoid an RC update. If not, then ensure _PAGE_DIRTY does not come across. Set _PAGE_ACCESSED as well to avoid RC update.

The radix guest code can has fewer restrictions about what context it can run in, so move this flushing out of assembly and have it use the Linux TLB flush implementations introduced previously. This allows powerpc:tlbie trace events to be used. This changes the tlbiel sequence to only execute RIC=2 flush once on the first set flushed, then RIC=0 for the rest of the sets. The end result of the flush should be unchanged. This matches the local PID flush pattern that was introduced in a5998fcb ("powerpc/mm/radix: Optimise tlbiel flush all case"). Signed-off-by:

When partition scope mappings are unmapped with kvm_unmap_radix, the pte is cleared, but the page table structure is left in place. If the next page fault requests a different page table geometry (e.g., due to THP promotion or split), kvmppc_create_pte is responsible for changing the page tables. When a page table entry is to be converted to a large pte, the page table entry is cleared, the PWC flushed, then the page table it points to freed. This will cause pte page tables to leak when a 1GB page is to replace a pud entry points to a pmd table with pte tables under it: The pmd table will be freed, but its pte tables will be missed. Fix this by replacing the simple clear and free code with one that walks down the page tables and frees children. Care must be taken to clear the root entry being unmapped then flushing the PWC before freeing any page tables, as explained in comments. This requires PWC flush to logically become a flush-all-PWC (which it already is in hardware, but the KVM API needs to be changed to avoid confusion). This code also checks that no unexpected pte entries exist in any page table being freed, and unmaps those and emits a WARN. This is an expensive operation for the pte page level, but partition scope changes are rare, so it's unconditional for now to iron out bugs. It can be put under a CONFIG option or removed after some time. Signed-off-by:

tlbies to an LPAR do not have to be serialised since POWER4/PPC970, after which the MMU_FTR_LOCKLESS_TLBIE feature was introduced to avoid tlbie locking. Since commit c17b98cf ("KVM: PPC: Book3S HV: Remove code for PPC970 processors"), KVM no longer supports processors that do not have this feature, so the tlbie locking can be removed completely. A sanity check for the feature is put in kvmppc_mmu_hv_init. Testing was done on a POWER9 system in HPT mode, with a -smp 32 guest in HPT mode. 32 instances of the powerpc fork benchmark from selftests were run with --fork, and the results measured. Without this patch, total throughput was about 13.5K/sec, and this is the top of the host profile: 74.52% [k] do_tlbies 2.95% [k] kvmppc_book3s_hv_page_fault 1.80% [k] calc_checksum 1.80% [k] kvmppc_vcpu_run_hv 1.49% [k] kvmppc_run_core After this patch, throughput was about 51K/sec, with this profile: 21.28% [k] do_tlbies 5.26% [k] kvmppc_run_core 4.88% [k] kvmppc_book3s_hv_page_fault 3.30% [k] _raw_spin_lock_irqsave 3.25% [k] gup_pgd_range Signed-off-by:

When KVM emulates VMX store, it will invoke kvmppc_get_vmx_data() to retrieve VMX reg val. kvmppc_get_vmx_data() will check mmio_host_swabbed to decide which double word of vr[] to be used. But the mmio_host_swabbed can be uninitialized during VMX store procedure: kvmppc_emulate_loadstore \- kvmppc_handle_store128_by2x64 \- kvmppc_get_vmx_data So vcpu->arch.mmio_host_swabbed is not meant to be used at all for emulation of store instructions, and this patch makes that true for VMX stores. This patch also initializes mmio_host_swabbed to avoid possible future problems. Signed-off-by:

Although it does not seem possible to break the host by passing bad parameters when creating a TCE table in KVM, it is still better to get an early clear indication of that than debugging weird effect this might bring. This adds some sanity checks that the page size is 4KB..16GB as this is what the actual LoPAPR supports and that the window actually fits 64bit space. Signed-off-by:

At the moment we only support in the host the IOMMU page sizes which the guest is aware of, which is 4KB/64KB/16MB. However P9 does not support 16MB IOMMU pages, 2MB and 1GB pages are supported instead. We can still emulate bigger guest pages (for example 16MB) with smaller host pages (4KB/64KB/2MB). This allows the physical IOMMU pages to use a page size smaller or equal than the guest visible IOMMU page size. Signed-off-by:

The other TCE handlers use page shift from the guest visible TCE table (described by kvmppc_spapr_tce_iommu_table) so let's make H_STUFF_TCE handlers do the same thing. This should cause no behavioral change now but soon we will allow the iommu_table::it_page_shift being different from from the emulated table page size so this will play a role. Signed-off-by:

Although Linux doesn't use PURR and SPURR ((Scaled) Processor Utilization of Resources Register), other OSes depend on them. On POWER8 they count at a rate depending on whether the VCPU is idle or running, the activity of the VCPU, and the value in the RWMR (Region-Weighting Mode Register). Hardware expects the hypervisor to update the RWMR when a core is dispatched to reflect the number of online VCPUs in the vcore. This adds code to maintain a count in the vcore struct indicating how many VCPUs are online. In kvmppc_run_core we use that count to set the RWMR register on POWER8. If the core is split because of a static or dynamic micro-threading mode, we use the value for 8 threads. The RWMR value is not relevant when the host is executing because Linux does not use the PURR or SPURR register, so we don't bother saving and restoring the host value. For the sake of old userspace which does not set the KVM_REG_PPC_ONLINE register, we set online to 1 if it was 0 at the time of a KVM_RUN ioctl. Signed-off-by:

This adds a new KVM_REG_PPC_ONLINE register which userspace can set to 0 or 1 via the GET/SET_ONE_REG interface to indicate whether it considers the VCPU to be offline (0), that is, not currently running, or online (1). This will be used in a later patch to configure the register which controls PURR and SPURR accumulation. Signed-off-by:

A radix guest can execute tlbie instructions to invalidate TLB entries. After a tlbie or a group of tlbies, it must then do the architected sequence eieio; tlbsync; ptesync to ensure that the TLB invalidation has been processed by all CPUs in the system before it can rely on no CPU using any translation that it just invalidated. In fact it is the ptesync which does the actual synchronization in this sequence, and hardware has a requirement that the ptesync must be executed on the same CPU thread as the tlbies which it is expected to order. Thus, if a vCPU gets moved from one physical CPU to another after it has done some tlbies but before it can get to do the ptesync, the ptesync will not have the desired effect when it is executed on the second physical CPU. To fix this, we do a ptesync in the exit path for radix guests. If there are any pending tlbies, this will wait for them to complete. If there aren't, then ptesync will just do the same as sync.

When a vcpu priority (CPPR) is set to a lower value (masking more interrupts), we stop processing interrupts already in the queue for the priorities that have now been masked. If those interrupts were previously re-routed to a different CPU, they might still be stuck until the older one that has them in its queue processes them. In the case of guest CPU unplug, that can be never. To address that without creating additional overhead for the normal interrupt processing path, this changes H_CPPR handling so that when such a priority change occurs, we scan the interrupt queue for that vCPU, and for any interrupt in there that has been re-routed, we replace it with a dummy and force a re-trigger.

Currently, the HV KVM guest entry/exit code adds the timebase offset from the vcore struct to the timebase on guest entry, and subtracts it on guest exit. Which is fine, except that it is possible for userspace to change the offset using the SET_ONE_REG interface while the vcore is running, as there is only one timebase offset per vcore but potentially multiple VCPUs in the vcore. If that were to happen, KVM would subtract a different offset on guest exit from that which it had added on guest entry, leading to the timebase being out of sync between cores in the host, which then leads to bad things happening such as hangs and spurious watchdog timeouts. To fix this, we add a new field 'tb_offset_applied' to the vcore struct which stores the offset that is currently applied to the timebase. This value is set from the vcore tb_offset field on guest entry, and is what is subtracted from the timebase on guest exit. Since it is zero when the timebase offset is not applied, we can simplify the logic in kvmhv_start_timing and kvmhv_accumulate_time. In addition, we had secondary threads reading the timebase while running concurrently with code on the primary thread which would eventually add or subtract the timebase offset from the timebase. This occurred while saving or restoring the DEC register value on the secondary threads. Although no specific incorrect behaviour has been observed, this is a race which should be fixed. To fix it, we move the DEC saving code to just before we call kvmhv_commence_exit, and the DEC restoring code to after the point where we have waited for the primary thread to switch the MMU context and add the timebase offset. That way we are sure that the timebase contains the guest timebase value in both cases. Signed-off-by:
