      perf record: Prevent override of attr->sample_period for libpfm4 events · ae5dcc8a

      Before:
      
        $ perf record -c 10000 --pfm-events=cycles:period=77777

      This was due to an ordering issue between libpfm4 parsing

      perf record: Set PERF_RECORD_PERIOD if attr->freq is set. · ce4326d2
      David Sharp authored
      evsel__config() would only set PERF_RECORD_PERIOD if it set attr->freq
      from perf record options. When it is set by libpfm events, it would not
      get set. This changes evsel__config to see if attr->freq is set outside
      of whether or not it changes attr->freq itself.

      perf test: Fix the "signal" test inline assembly · 8a39e8c4
      Jiri Olsa authored
      When compiling with DEBUG=1 on Fedora 32 I'm getting crash for 'perf

      It's caused by the symbol __test_function being in the ".bss" section:

      I guess most of the time we're just lucky the inline asm ended up in the

      section clauses.

      KVM: SVM: Periodically schedule when unregistering regions on destroy · 7be74942
      David Rientjes authored
      There may be many encrypted regions that need to be unregistered when a
      SEV VM is destroyed.  This can lead to soft lockups.  For example, on a
      host running 4.15:
      
      watchdog: BUG: soft lockup - CPU#206 stuck for 11s! [t_virtual_machi:194348]
      CPU: 206 PID: 194348 Comm: t_virtual_machi
      RIP: 0010:free_unref_page_list+0x105/0x170
      ...
      Call Trace:
       [<0>] release_pages+0x159/0x3d0
       [<0>] sev_unpin_memory+0x2c/0x50 [kvm_amd]

       [<0>] do_signal+0x31/0x130
      
      Although the CLFLUSH is no longer issued on every encrypted region to be
      unregistered, there are no other changes that can prevent soft lockups for
      very large SEV VMs in the latest kernel.
      
      Periodically schedule if necessary.  This still holds kvm->lock across the
      resched, but since this only happens when the VM is destroyed this is
      assumed to be acceptable.

      KVM: MIPS: Change the definition of kvm type · 15e9e35c
      Huacai Chen authored
      MIPS defines two kvm types:
      
       #define KVM_VM_MIPS_TE          0
       #define KVM_VM_MIPS_VZ          1
      
      In Documentation/virt/kvm/api.rst it is said that "You probably want to
      use 0 as machine type", which implies that type 0 be the "automatic" or
      "default" type. And, in user-space libvirt use the null-machine (with
      type 0) to detect the kvm capability, which returns "KVM not supported"
      on a VZ platform.
      
      I try to fix it in QEMU but it is ugly:
      https://lists.nongnu.org/archive/html/qemu-devel/2020-08/msg05629.html
      
      And Thomas Huth suggests me to change the definition of kvm type:
      https://lists.nongnu.org/archive/html/qemu-devel/2020-09/msg03281.html
      
      So I define like this:
      
       #define KVM_VM_MIPS_AUTO        0
       #define KVM_VM_MIPS_VZ          1
       #define KVM_VM_MIPS_TE          2
      
      Since VZ and TE cannot co-exists, using type 0 on a TE platform will
      still return success (so old user-space tools have no problems on new
      kernels); the advantage is that using type 0 on a VZ platform will not
      return failure. So, the only problem is "new user-space tools use type
      2 on old kernels", but if we treat this as a kernel bug, we can backport
      this patch to old stable kernels.
