2020-03-20perf/x86/intel/uncore: Add box_offsets for free-running countersKan Liang1-1/+4
The offset between uncore boxes of free-running counters varies, e.g. IIO free-running counters on Ice Lake server. Add box_offsets, an array of offsets between adjacent uncore boxes.

2020-03-20perf/core: Fix reversed NULL check in perf_event_groups_less()Dan Carpenter1-1/+1
This NULL check is reversed so it leads to a Smatch warning and presumably a NULL dereference. kernel/events/core.c:1598 perf_event_groups_less() error: we previously assumed 'right->cgrp->css.cgroup' could be null (see line 1590) Fixes: 95ed6c707f26 ("perf/cgroup: Order events in RB tree by cgroup id") Signed-off-by: Dan Carpenter <[email protected]> Signed-off-by: Peter Zijlstra (Intel) <[email protected]> Link: https://lkml.kernel.org/r/20200312105637.GA8960@mwanda

2020-03-20x86/optprobe: Fix OPTPROBE vs UACCESSPeter Zijlstra2-0/+26
While looking at an objtool UACCESS warning, it suddenly occurred to me that it is entirely possible to have an OPTPROBE right in the middle of an UACCESS region. In this case we must of course clear FLAGS.AC while running the KPROBE. Luckily the trampoline already saves/restores [ER]FLAGS, so all we need to do is inject a CLAC. Unfortunately we cannot use ALTERNATIVE() in the trampoline text, so we have to frob that manually.

2020-03-17perf report: Fix no branch type statistics report issueJin Yao1-5/+4
Previously we could get the report of branch type statistics. For example: # perf record -j any,save_type ... # t perf report --stdio # # Branch Statistics: # COND_FWD: 40.6% COND_BWD: 4.1% CROSS_4K: 24.7% CROSS_2M: 12.3% COND: 44.7% UNCOND: 0.0% IND: 6.1% CALL: 24.5% RET: 24.7% But now for the recent perf, it can't report the branch type statistics. It's a regression issue caused by commit 40c39e304641 ("perf report: Fix a no annotate browser displayed issue"), which only counts the branch type statistics for browser mode. This patch moves the branch_type_count() outside of ui__has_annotation() checking, then branch type statistics can work for stdio mode.

2020-03-17perf/amd/uncore: Add support for Family 19h L3 PMUKim Phillips2-8/+27
Family 19h introduces change in slice, core and thread specification in its L3 Performance Event Select (ChL3PmcCfg) h/w register. The change is incompatible with Family 17h's version of the register. Introduce a new path in l3_thread_slice_mask() to do things differently for Family 19h vs. Family 17h, otherwise the new hardware doesn't get programmed correctly. Instead of a linear core--thread bitmask, Family 19h takes an encoded core number, and a separate thread mask. There are new bits that are set for all cores and all slices, of which only the latter is used, since the driver counts events for all slices on behalf of the specified CPU. Also update amd_uncore_init() to base its L2/NB vs. L3/Data Fabric mode decision based on Family 17h or above, not just 17h and 18h: the Family 19h Data Fabric PMC is compatible with the Family 17h DF PMC.

2020-03-14KVM: nVMX: avoid NULL pointer dereference with incorrect EVMCS GPAsVitaly Kuznetsov1-2/+3
When an EVMCS enabled L1 guest on KVM will tries doing enlightened VMEnter with EVMCS GPA = 0 the host crashes because the evmcs_gpa != vmx->nested.hv_evmcs_vmptr condition in nested_vmx_handle_enlightened_vmptrld() will evaluate to false (as nested.hv_evmcs_vmptr is zeroed after init). The crash will happen on vmx->nested.hv_evmcs pointer dereference. Another problematic EVMCS ptr value is '-1' but it only causes host crash after nested_release_evmcs() invocation. The problem is exactly the same as with '0', we mistakenly think that the EVMCS pointer hasn't changed and thus nested.hv_evmcs_vmptr is valid. Resolve the issue by adding an additional !vmx->nested.hv_evmcs check to nested_vmx_handle_enlightened_vmptrld(), this way we will always be trying kvm_vcpu_map() when nested.hv_evmcs is NULL and this is supposed to catch all invalid EVMCS GPAs. Also, initialize hv_evmcs_vmptr to '0' in nested_release_evmcs() to be consistent with initialization where we don't currently set hv_evmcs_vmptr to '-1'.

2020-03-14KVM: x86: Initializing all kvm_lapic_irq fields in ioapic_write_indirectNitesh Narayan Lal1-2/+5
Previously all fields of structure kvm_lapic_irq were not initialized before it was passed to kvm_bitmap_or_dest_vcpus(). Which will cause an issue when any of those fields are used for processing a request. For example not initializing the msi_redir_hint field before passing to the kvm_bitmap_or_dest_vcpus(), may lead to a misbehavior of kvm_apic_map_get_dest_lapic(). This will specifically happen when the kvm_lowest_prio_delivery() returns TRUE due to a non-zero garbage value of msi_redir_hint, which should not happen as the request belongs to APIC fixed delivery mode and we do not want to deliver the interrupt only to the lowest priority candidate. This patch initializes all the fields of kvm_lapic_irq based on the values of ioapic redirect_entry object before passing it on to kvm_bitmap_or_dest_vcpus().

2020-03-14KVM: VMX: Condition ENCLS-exiting enabling on CPU support for SGX1Sean Christopherson1-2/+14
Enable ENCLS-exiting (and thus set vmcs.ENCLS_EXITING_BITMAP) only if the CPU supports SGX1. Per Intel's SDM, all ENCLS leafs #UD if SGX1 is not supported[*], i.e. intercepting ENCLS to inject a #UD is unnecessary. Avoiding ENCLS-exiting even when it is reported as supported by the CPU works around a reported issue where SGX is "hard" disabled after an S3 suspend/resume cycle, i.e. CPUID.0x7.SGX=0 and the VMCS field/control are enumerated as unsupported. While the root cause of the S3 issue is unknown, it's definitely _not_ a KVM (or kernel) bug, i.e. this is a workaround for what is most likely a hardware or firmware issue. As a bonus side effect, KVM saves a VMWRITE when first preparing vmcs01 and vmcs02. Note, SGX must be disabled in BIOS to take advantage of this workaround [*] The additional ENCLS CPUID check on SGX1 exists so that SGX can be globally "soft" disabled post-reset, e.g. if #MC bits in MCi_CTL are cleared. Soft disabled meaning disabling SGX without clearing the primary CPUID bit (in leaf 0x7) and without poking into non-SGX CPU paths, e.g. for the VMCS controls.

2020-03-14iommu/amd: Fix IOMMU AVIC not properly update the is_run bit in IRTESuravee Suthikulpanit1-2/+2
Commit b9c6ff94e43a ("iommu/amd: Re-factor guest virtual APIC (de-)activation code") accidentally left out the ir_data pointer when calling modity_irte_ga(), which causes the function amd_iommu_update_ga() to return prematurely due to struct amd_ir_data.ref is NULL and the "is_run" bit of IRTE does not get updated properly. This results in bad I/O performance since IOMMU AVIC always generate GA Log entry and notify IOMMU driver and KVM when it receives interrupt from the PCI pass-through device instead of directly inject interrupt to the vCPU. Fixes by passing ir_data when calling modify_irte_ga() as done previously.

2020-03-14iommu/vt-d: Ignore devices with out-of-spec domain numberDaniel Drake1-0/+8
VMD subdevices are created with a PCI domain ID of 0x10000 or higher. These subdevices are also handled like all other PCI devices by dmar_pci_bus_notifier(). However, when dmar_alloc_pci_notify_info() take records of such devices, it will truncate the domain ID to a u16 value (in info->seg). The device at (e.g.) 10000:00:02.0 is then treated by the DMAR code as if it is 0000:00:02.0. In the unlucky event that a real device also exists at 0000:00:02.0 and also has a device-specific entry in the DMAR table, dmar_insert_dev_scope() will crash on:   BUG_ON(i >= devices_cnt); That's basically a sanity check that only one PCI device matches a single DMAR entry; in this case we seem to have two matching devices. Fix this by ignoring devices that have a domain number higher than what can be looked up in the DMAR table. This problem was carefully diagnosed by Jian-Hong Pan.
